Dirty old river, must you keep rolling; Flowing into

the night… That’s the opening line to the Kink’s

“Waterloo Sunset,” as its composer, Dave Davies,

observed the world in 1967 from Waterloo Bridge

over the Thames in London. The bridge, FYI, is

near Waterloo Station, a destination I had some

diffi culty fi nding about a year ago when I was

in London to meet with UK lighting designers

Speirs and Major about a cool SSL product they

were helping develop with Cree—the Aeroblades

fi xtures we profi led in July.

Why am I musing about British bridges and

train stations, or lighting designers for that mat-

ter? Just the other day the lighting consultants

sent me a press release about a project involving

LED they’re doing at the city’s University of Arts.

It got me thinking about my trip, a year ago, and

the aforementioned tune popped in my head,

which in turn, triggered another memory from

a November past: Back in 2009, coming off the

second ArchLED conference, I relayed a story

from the old Rocky and Bullwinkle show about a

race between one of the fi rst steam locomotive

prototypes and a horse and buggy. The cartoon-

ish humor lied in the fact that while the train

was doing well against the horse, it crashed to

spectacular sound effects and explosive visual

symbols when it came through a tunnel that,

unfortunately, was completed only half way.

Later in the episode, after the train got going

again after overcoming the tunnel obstacle, the

cartoon’s protagonist, in approaching an upcom-

ing river chasm, asks the locomotive’s inventor

about foreseeable problems they might encounter

with the bridge. The inventor calmly notes that

it might indeed be an issue, as in this instance,

plans for the bridge were only 50% complete.

More spectacular sound effects and explosive

visual symbols…

So three years later, what’s the status on

that 50% tunnel and bridge? I observe the steam

engine—or LED engine—prototypes are almost

fully developed. That’s the good news, but much

of the track, tunnels and bridges remain unfi n-

ished as this technology continues to develop.

Not to despair, I have a notion I believe may

help, at least with the laying of infrastructure:

Like that Kinks song that keeps popping into

my head when I think of London, the power

of psychographics should not to be underesti-

mated. But the association that matters, in this

case, is connecting SSL with a powerful ally: the

zero-energy building movement. SSL, I believe,

needs something to differentiate it from the rest

of the crowd, and that differentiator is the fact

that SSL so neatly fi ts into the net-zero model.

Let’s begin with the critical net-zero tenet that

buildings should generate more power on their

own, independent of the grid. LED lighting, which

can operate on low-voltage DC-DC systems, as the

EMerge Alliance has so effectively demonstrated,

means LED fi xtures can directly be powered by a

photovoltaic source, even wind energy—providing

a direct, and achievable function for the rather

nebulous role alternative and renewable power

devices have to play in net-zero projects—at least

from the aspect of doing so without having to

construct giant wind farms or cover every sq. ft.

of one’s facility with solar panels.

Add to the equation its low energy consump-

tion, controllability, color tunability, long life

and modularity for future scalability—SSL is the

logical electric illumination source of net zero. So,

what I’m getting at is the SSL community must

work on developing a catchy Waterloo Sunset-like

melody, one that will bridge one with the other.

Of course, we must also get to work on fi nishing

that bridge design, and building it for that matter,

before we all end up in the drink.•

The 50% Bridge Revisited

Despite rapid product improvement, a great deal of supporting LED infrastructure remains to be laid. Perhaps it’s time to switch this train to the Net-Zero track.

ABOVE: The performance range was similar to LED Lighting Facts, and in general, the LED lamps had higher effi cacy

than both incandescent and CFL BR30/R30 lamps. The lumen output has increased over time; many lamps now match

the lumen output of 65- or 75-watt incandescent BR30/R30 lamps.

ABOVE: Excluding one product with very high effi cacy (91 lm/watt), the Series 16 products had luminous effi cacies between 51 and 65 lm/watt. This is favorable compared to other light source types commonly used in directional lamps, and should continue to rise.

Round 16 of DOE’s latest CALiPER testing focuses on directional BR30 and R30 Edison-base LED lamp retrofi ts. While this is a smaller category than the PAR lamp target, the use of the R and BR lamp is widespread in residential and cost-sensitive commercial spaces. The lamps tested are direct replacements for ineffi cient incandescent and CFL refl ector lamp products, where energy savings is the primary value added. The report reveals several signifi cant issues, most notably the disconnect between some LED products entering the market and market reality. In this case, while the LED products do duplicate the light output, and deliver energy savings, their high cost misses the mark for customers who choose “R” and “BR” lamps mainly due to their price. While some may purchase the lamps due to interest in LEDs, there are numerous “PAR” retrofi t products that will perform better at the same or lower initial cost. As far as testing results, for clarity, rather than lumping all directional sources into a single category, it is best considered when divided into two sub-categories: Semi-directional—products without focusing optics; and Focused-directional—products that produce a distinct directional emis-sion. The former include “R,” “ER” and “BR” lamps. The original form of these lamps utilizes internal silvering and a blown-glass envelope to produce hemispherical distributions. This classifi cation now includes CFL refl ector lamps. Focused directional sources, identifi ed as “MR” and “PAR” lamp forms, use molded-glass refl ectors with specular alumi-nized coating and glass lenses to produce high center beam energy and greater control. Round 16 focused exclusively on the LED products targeted as replacements to the lower performing BR30 and R30 semi-directional lamps. The application of these lamps includes recessed down-lighting,

directional display and accent lighting. as the overly broad light distri-bution is cut off by baffl es and fi xture bodies. Lacking a center beam focus, these lamps are frequently low performing in application.

Cost ConsiderationsA key consideration in R and BR lamps is that they are primarily chosen for fi rst-cost over performance. The LED versions tested in Round 16 range in price from $35 to $104 (mean $55.39), opposed to the incum-bent incandescent lamp cost of $2.80, or a CFL BR30 cost of $9.90. This raises the question of whether these products will be accepted in the highly cost-sensitive target market they are designed to satisfy. The lamps tested consumed between 6 and 14.3 watts, with a mean effi cacy of 59 lm. per watt—only slightly better than the CFL replace-ment benchmarks which tested at 39-51 lm. per watt. In comparing the CFL to an LED R or BR lamp with identical optical distribution, there is little to support the premium cost of the LED products in this category. Six of the 13 LED lamps tested produced distributions virtually identical to the CFL replacement it was being benchmarked against, while only one came near the slightly narrower incandescent bench-mark. This seems at odds with the application of the inherently directional LED light source, which is erased by use of diff users, which destroys any justifi cation of their high price premium beyond potentially longer service life.

Photometric PerformanceUltimately, how well a lamp performs in application falls on its pho-tometric performance. In this case, the majority of the tested LED replacements were apparently designed under the assumption that the CFL replacement R lamp was the desired target—which appears to be designed to replace the 65-watt BR lamp. However, four of the LED re-placements delivered greater optical control with slightly narrower beam patterns and moderately improved fi eld angle control. Compared to the other lamps, these products would produce improved performance in enclosed fi xture designs, representing a composite improvement in fi x-ture effi ciency. However, for the same price, a PAR30 LED replacement product with even greater optical control and directional energy could be obtained that will outperform all of the lamps tested in application. Round 16 illustrates the disconnect that exists between some LED products entering the market and actual market reality. In this case, while the LED products do duplicate the light output, and deliver energy savings, their high cost misses the mark for customers who choose “R” and “BR” lamps mainly due to their price. While some may purchase the lamps due to interest in LEDs, there are numerous “PAR” retrofi t products that will perform better at the same or lower initial cost. For this reason, one must question the need for this class of LED replace-ment lamps altogether.•

Combining a grid-based structure with a dazzling display of Mylar balloons and LED lighting arrays from Traxon Technologies, Cloudscape also served as a popular meeting place. Designers connected the company’s fl exible Dot XL and String RGB products to motion sensors to produce light shows that grew in intensity with the crowd’s movements below.

The project involved replacing CFL downlights and linear fl uorescent fi xtures with CR22 architectural troff ers from Cree. The new luminaires were installed in the building’s American Grill, sundry shop and main hallway, and should reduce related energy demand by 33%. Plus, the LEDs’ extended life should also help reduce maintenance requirements.•

room for newer innovators. In an ironic twist, one

of the most vocal proponents of LED displacement

of conventional manufacturers, Cree, purchased

Ruud lighting, a manufacturer of conventional

products as well as LED standout brand BetaLED.

The explosion of product and manufacturers

entering the market leads to speculation that this

is the boom that will lead to an inevitable bust.

While it may appear this is the case, SSL is still

a very young technology to the lighting market,

attaining less than 10% market share overall

to date (according to DOE reports). That means

there is plenty of opportunity to grow, even in a

crowded market space. Certainly, at some future

point there will be over-saturation leading to a

bust cycle. This is a self correcting feature of free

markets. However, there is no indication that

2012 is anywhere near this event horizon, so be

prepared for more expansion in the near term.

Of greater concern is the supply of LEDs

themselves. In 2012, shortages of substrate mate-

rials and phosphor supplies, plus limited inven-

tories due to obsolescence cycles, presented very

real obstacles to deployment efforts. If left uncor-

rected, this will put the brakes on market expan-

sion, regardless of demand growth. To answer

this, in 2012 many LED vendors shifted focus to

luminance volume has dropped signifi cantly.

Roadway and area luminaires once employ-

ing hundreds of LEDs are giving way to newer

approaches using less a fraction of that num-

ber. The result is more compact designs and

lower luminaire costs. High intensity sources

also increase optical effi ciency. However, the

downside to brighter LEDs is potential for glare,

and eye damaging intensity. IEC Standards

62471-2006 and ANSI/IES RP-27 have evolved to

address this issue directly, with test procedures

and exposure limits defi ned, including blue light

emission associated with white LED sources.

Use More Low and Mid Power, Lower Cost LEDs per LuminaireThe improvement in LED effi cacy applies to

products at all energy levels. This has given rise

to products utilizing low and mid-power LEDs

in tightly spaced arrays to deliver more uniform

luminous presence. This is made possible by the

low cost of the lesser LEDs. The end result is the

potential to create luminous surfaces without vis-

ible dots and spots, while thermal control issues

are reduced. This applies well to soft general light

sources and linear strips, where individual LED

visibility detracts from visual appearance.

PRODUCT AVAILABILITYBetween 2010 and 2012, there has been an explo-

sion in available SSL product. Conventional and

new entry SSL manufacturers have increased the

number of introduced offerings of SSL products

signifi cantly. This is refl ected in the listings at

Lighting Facts, which has ballooned from a few

hundred to thousands—as has the number of

Energy Star products available. Lightfair and

Light+Build were overwhelming in their array of

LED products, components, sources, replacement

lamps, and supporting controls. The growing

demand from customers to for LED products, and

building customers asking for LED alternatives in

lighting decision making is driving manufacturers

to accelerate product development efforts.

Most noteworthy is the mix of new and

incumbent players, with no signs of LED induced

attrition. This is counter to the assertion that the

transition to solid-state would create a wholesale

washout of conventional manufacturers to make

metrics. While the discussion of CQS continues

in the CIE, CRI remains the only established

standard for defi ning color quality. The longer

this process takes to be resolved, the more costly

it will be for manufacturers to re-test or recalcu-

late products and update literature and web sites.

Because of this, and a seemingly soft demand

from the market to address this, there is no pro-

jected end to this issue in sight.

WINNING HEARTS AND MINDSOf all areas of weakness in the current deploy-

ment approach to solid-state lighting, there

remains a persistence to apply the technology

within the myopic focus on energy savings

through retrofi tting the Edison socket inventory,

and directly displacing conventional products

with like SSL products. Because of this, many of

the greatest successes in SSL deployment are

hidden from view. By pursuing a one-for-one

replacement strategy—which is the easiest from

a marketing and sales perspective—spotting a

solid-state application requires a trained eye to

see where they actually are. Some contend that

this is desirable, as it removes any negative reac-

tion, similar to that CFL experienced. However,

this dilution of visibility conceals the technology,

which makes all the hype seem out of proportion

to observable reality.

Further, every effort to make SSL products

mimic conventional sources assumes the conven-

tional is more desirable to all new alternatives

where SSL can shine as a superior choice.

In the consumer market, this is aggravated

by big box retailers displaying LED products

alongside CFL sold at a fraction the price, on

shelves shared with familiar incandescent prod-

ucts even lower in cost.

As has been stated in this publication

many times, dismissing approaches to employ

solid-state to improve visual performance, and

superior aesthetics creates a price disadvantage

to LED technology that will take several more

years to overcome. With a few exceptions, as of

2012 solid-state lighting remains short of enticing

customers to see it as a “must-have” value. When

a T8 or T5 fl uorescent lamp costing a few dollars

STANDARDS DEVELOPMENT2012 was a slower year for rolling out new

standards than has been experienced in the

period from 2008 to 2011. While several com-

mittees made progress on topics of color, fl icker,

and safety, the most notable standards progress

occurred with the launch of the Energy Star

Luminaire section, and the fi rst of Zhaga Consor-

tium module release. Another related release

was by the Federal Trade Commission, who put in

place their Lighting Facts labeling requirements

effective January 2012. This differs from the DOE

Lighting Facts program, which is voluntary. The

FTC requirements are mandatory on SSL replace-

ment lamps sold through consumer outlets. The

slower pace of new standards released is a good

sign, as it indicates most of the larger issues of

testing and communication of color, life, per-

formance, and power consumption have been

addressed.

for SSL is for replacement of halogen MR, R and

and energy consumption of HID lamps.

There are exceptions to the replacement

exterior products have seen widespread success.

These products deliver value through tunability

of in light output and optics, in a modular format

well suited to cove, display, accent and wash

applications. Further, lower profi les, hardier envi-

ronmental enclosures, long life and low energy

use add up to advantages that have energized

this category of SSL product. Color LED effects

also remain a solid value-adding proposition.

steadily while performance continues to improve.

Further, color consistency in LED devices has

advanced dramatically with improved binning

and production controls, as well as new technolo-

gies in the application and composition of phos-

phors employed. The proliferation of greater-

than 90CRI LEDs in desirable CCT colors has also

expanded appreciably.

Another signifi cant area of improvement

in 2012 has been the availability of LED prod-

ucts able to operate effectively on conventional

controls (dimmers). Several products now offer

full range dimming from Triac controls. This,

alongside advancements in dimming availability

overall, development of wireless technologies,

and intuitive intelligent controls is putting LED a

step up on conventional products.

OLED AND PLASMA SOURCES2012 saw the introduction of several OLED

products. The most notable were from Acuity

(see above), which presented several innovative

designs using the new technology to create light

forms of distinct and unique character.

While cost, availability, color and life issues

remain concerns, 2012 was a turning point for

OLED from being a lab concept to a viable candi-

date to step into the realm of the practical.


OLED TURNS A CORNEROLED development is seeing tangible results. Acuity,

this past year, introduced a number of OLED luminaires,

including the Revel KIndred (left), and the Canvis, a fl exible

fi xture that can be manipulated in its shape. While OLED

as a whole still has some uphill battles—cost, availability,

color and life issues—2012 was defi nitely a turning point

from OLED being a primarily a lab concept to a fi rst-time

candidate for practicality. Images courtesy of Acuity.

Advancements in Plasma light sources also

saw improvement in 2012. Now available in 90+

CRI and colors more appropriate to broad lighting

use, plasma presents a signifi cant improvement

in optical control and compact source archi-

tecture that HID and LED are unable to equal.

While limited in real utility to applications where

greater than 10,000 lumens are needed, such as

open area, roadway interchange, large fl ood, and

sports lighting, plasma is an excellent companion

to LED technology.

A COMPLEX VISION - CONCLUSIONPerhaps the most noteworthy development of

2012 was that advancements occurred in many

areas, from the technology to improvements in

the market itself. The raw proliferation of solid-

sate products is a signifi cant and needed stage

for the technology to move from slow to rapid

advancement.

With a larger number of players compet-

ing for customer attention, innovation will shift

from simplistic metrics and low-hanging fruit, to

delivery of greater value-added offerings.

While there are many manufacturers offer-

ing solid-state products concentrated on large-

volume segment opportunities. This is an obvious

marketing ploy, and sells well to non-lighting

investors who respond to big numbers over

esoteric design values. This has begun to shift

in 2012 as privately owned and conventional

manufacturers who know the inner workings of

lighting have become more active. The result is

an emergence of new product designs of unique

and special character. From lighting that changes

color in response to its dimming state, wireless

roadway lighting that communicates condition

states to a central database, lighting controls that

harvest their own power for operation, and BIM

integration, solid-state lighting is maturing in

both sophistication as well as price and perfor-

mance.

If 2010 was a tipping point of attention

toward SSL, 2012 marks the beginning of true

transformation. There are a few more hurdles to

be overcome. However, the next four will be when

solid-state becomes the source of choice for all

but a few segments of lighting.•

GREAT NEW PRODUCTSA number of LED products are beginning to diff erenti-

ate themselves from the pack, taking advantage of SSL's

unique properties. For example, Philips' Ledalite introduced

its TruGroove luminaire, a sleek, recessed LED fi xture that

fi ts unobtrusively into the ceiling providing a value archi-

tects have clamored for, for years .

A MATURING INDUSTRYLED manufacturers are beginning to take a very diff erent

approach to marketing their products. For example, Holo-

phane is putting its money where its mouth is, so to speak,

in the creation of its night time interactive demo, where

customers are able to walk through a series of outdoor il-

luminated environments at their Granville, Ohio campus, to

experience, fi rst hand, the quality of diff erent LED sources.

2. Energy-use restrictions

have made retail owners consider

not only energy costs to light their

stores, but what lighting does to

enhance the sales appeal of prod-

ucts on display.

3. Retail lighting presents

today’s lighting practitioners the

opportunity to utilize the palette

of lighting options as an applied

art form in the built environ-

ment, enhancing everyday living

experiences.

The Arrow is Pointing Up

The scope of activity of the retail

store design and construction

market is still growing. As the

industry is moving into its high-

grossing fourth quarter, U.S. retail

industry sales have already risen

to $2.57 trillion, up 3.5% year-to-

date. “Pent-up demand is turning

desires into needs, which is one

reason why consumers have begun

opening up their wallets,” says NRF

chief economist Jack Kleinhenz.

Other observers predict a

year-end increase of up to 4.5%,

citing a strong back-to-school

season. Retailers are closely track-

ing factors such as unemployment,

election results, and inventory

levels that could throw a wrench in

holiday results.

Jerry Storch, Toys R Us chair-

man and CEO, also dismisses the

notion that stores like his are a

dying breed to be replaced by Inter-

net-only giants. He put the cost of

“Direct-to-Home” e-commerce 1.5×

to 2× higher than that of the classic

method of shipping inventory to

stores where customers purchase

items and take them home.

Still, in other countries and

income levels, retail’s current vol-

ume is spotty. Sales are down 19%

in Australia, and up just 1.8% in the

U.K. At the top end of the market,

however, most luxury labels are

tallying strong numbers. Prada,

which in the past year opened 28

stores in countries such as Brazil,

Morocco and the Ukraine, acknowl-

edges the effects of political

troubles on the southern shores of

the Mediterranean, but according

to CEO Patrick Bertelli, signs for

these problems have been evident

for years. Prada experienced a 60%

leap in total volume for the current

fi scal period.

Stephen I. Sadove, CEO of

Saks Inc., is also concerned about

the global economic situation,

elections, and the fi scal situation.

“But we feel confi dent about the

long-term health of luxury, about

growth in the sector and the oppor-

tunities that are out there.”

The Forces Of Retail

The global economy is a force moving retailers and wholesal-ers to expand scope and reach to increase market share, revenue and customer base. Investment in employees, prod-uct design, new store openings, and marketing are paying off for retailers who are expanding their international presence in order to become less depen-dent upon a local, regional or national economy. That said, the U.S. is still considered a mecca for retailers seeking an international presence in a stable marketplace. Advances in technology are another force transforming retailing itself as well as the shopping experience. Respond-ing to increasing customer de-mands, retailers are giving local, national and global customers access to merchandise, service, and product information, tai-lored to their requests. Many retailers and whole-salers are also being smarter about their real estate, opening smaller stores, minimizing their footprint while increasing their sales-to-square foot ratio. Designers and manufactur-ers with a desire to tell their own brand story and infl uence the customer experience are increasingly becoming retailers, creating an upscale environ-ment for their luxury and aspirational products. These signifi cant trends, growing in momentum in the U.S. and internationally, are the drivers that signify that retail is undergoing global transforma-tion, prompting predictions that within fi ve years the current business model will be nearly unrecognizable.

Vitrashop Group, Birsfelden, Swit-

most likely to accept sustainability

as a strategy if tangible results are

apparent. “Some of the key aspects

are energy-effi cient lighting,

thermally insulated glazing, and

state-of-the-art air conditioning

technologies that save energy.”

Additionally, a growing num-

ber of retail decision-makers, he

indicates, are asking suppliers how

their products are made, and how

the products can be safely disposed

of. The store design industry is cer-

tainly in the "awareness" phase as

far as sustainability is concerned.

Rapid progress is being made in

areas where energy consumption—

and thus costs—can be reduced

measurably, for lighting, and in

food retail, for refrigeration and

think-tank, EHI, found that 25% of

energy costs in the food retail sec-

tor go toward lighting, and in the

non-food section, lighting accounts

for up to 75% of energy costs.

“Against a background of rising

energy prices," EHI attests, "there's

a renewed focus on more effi cient

lighting, including LED."

In concert, big box and

department stores are shrinking

the footprints of new stores, while

shuttering older outlets, and reduc-

ing the size of existing outlets. For

example, Neiman Marcus, with

stores typically in the 200,000-sq.-

ft. category, is monitoring the

success of its recently opened

87,000-sq.-ft. store in Walnut Creek,

California. Similarly, Staples is

cutting the size of 30 of its U.S.

stores—1% of its U.S. total. Wal-

Mart, too, is embracing this trend,

opening fi ve Neighborhood Market

stores in California’s Central Valley,

ranging in size from 31,000 to

55,000 sq .ft., bringing the total for

of this smaller-sized format to 200

nationwide. Kohl’s, which operates

1,146 stores, is unveiling 11 small-

format stores.

Catering to the Shoe Lover

Perhaps one item that's recession-

proof at a global level is shoes.

Shoes have become the high-prof-

itable, fast-turnover darling of the

retail industry, at all price points.

“The footwear market was the last

to feel the pain of the recession and

is the fi rst to feel the gain of the

recovery, and women are leading

the charge,” says industry analyst

Marshal Cohen of The NPD Group,

Port Washington, N.Y.

Total shoe sales for 2010

were up 7.2% to $34.6 billion,

with women’s shoe sales account-

ing for approximately 60% of all

sales. Department and high-end


specialty stores are boosting their

shoe operations with extensive

improvements. New York City fl ag-

ships, including Barneys, Saks Fifth

Avenue and Macy’s—in the process

of a $400 million upgrade of its

square-block-long Herald Square

store will devote 63,000 sq. ft. to

shoe selling and stock space.

At the Saks fl agship store, its

high-volume shoe department has

undergone a 17,000-sq.-ft. expan-

passionate about shoes, get a rush

each time they buy a new pair and

love to share that latest shoe-

DSW’s senior vice president of mar-

keting for the $2 billion chain. “It’s

the company’s mission to unlock

the emotional kick consumers get

every time they buy a new pair,”

says Cook.

Last year, DSW sold 30 million

pairs of shoes in their 344 stores.

Architect David Schwing, head of

the retail store design studio at

BAR Architects, San Francisco, has

designed several DSW stores, and

notes lighting plays a critical role.

“A customer will feel comfortable

in the store, understand product

and color choices, and read product

information and sizing easily only

if lighting levels accurately portray

the materials and colors,” says

Schwing.

“Foot Jewelry” is how interna-

tional store design consultant Ken

Nisch categorizes today’s consumer

attitude toward footwear. “Shoes,

along with eyewear, are where the

excitement is at retail now,” says

architect Nisch, CEO of JGA, South-

fi eld, Mich. “From casual to athletic

to dress, shoes have evolved into

an important accessory,” Nisch

observes in his advice to clients

worldwide on merchandise presen-

tation strategy. “Attractive lighting

art of selling footwear,” he says.

Even the traditionally conser-

vative men’s apparel and acces-

sory market has taken on new

life. Joshua Schulman, president

of New York’s Bergdorf Goodman,

says that shoes and men’s wear are

one of the fastest growing areas of

the overall luxury business.

Macy’s has announced a

105,000-sq.-ft. men’s store for 2014

completion in Fashion Show Mall,

Las Vegas. MenScience, makers of

men’s skin care products, opened

its fi rst major branch in New York’s

SoHo section, featuring a bi-level

space and private treatment rooms

on the lower level.

So what's lighting got to do

with it? Retail management execu-

tives understand that track light-

ing and rows of recessed adjustable

lamps aren’t the key to help move

merchandise in today’s hyper-

competitive environment. Creative

solutions devised by lighting

designers can motivate purchasing

at all price points.

For new stores, such as Nei-

man Marcus’ Walnut Creek branch,

the interior has an open, salon look

with plenty of daylight. “Controls

were selected to balance the level

of daylight allowed and the Title

24 code compliance requirement

for all lighting adjacent to daylit

areas,” explains lighting designer

Bernard V. Bauer of Integrated

Lighting Concepts, Westlake Vil-

lage, Calif.

The store is illuminated

approximately one-third with

ceramic metal halide accent light

and two-thirds with Silver IR

incandescent accent lights. LED is

used for casework and specialty

applications.

LEDs for their long life and cali-

brated beam angles.

renovation of the four-level,

100,000-sq.-ft. Bristol store, the

objective was to impart a premium

feel for a value retailer on a site

that has been a landmark build-

ing for other U.K. retailers before

Primark. “The distinctive curved

end of the ‘ship-shape’ plan is

illuminated externally with LEDs to

create a grid of light at night that

follows the contour of the building

with minimal energy consump-

tion,” Dalziel relates. “The general

lighting level is low, with a reliance

on directional rather than ambient

sources to create a more intimate

experience."

Beyond more traditional applica-

tion, retail lighting for exterior

and interior retail spaces can

demonstrate elegant and original

integrated interpretations that

are both artistic and functional. A

prime example is the Wintergar-

den Shopping Centre in Brisbane,

Australia, which has three street

frontages that are a complex

expression of nature, geometry,

layering and illumination. Designed

by Melbourne-based Studio 505

architects, the lighting feature

is created of layers pinned off

the building’s façades. Oversized

butterfl ies alight on the spider-

web-like metal background panels.

snow to autumn, to sunsets.

Sea Change?

Wintergarden is off the charts as

a piece of integrated illuminated

urban art. Overhead lighting for

Breuninger's major shoe depart-

ment is by a light artist. World-

class architects like David Adjaye,

who did Proenza Schouler, are

being commissioned to design for

retail, and they understand the

expertise of someone like Paul

Gregory who did the lighting. It

wasn't always the case, but today

retail lighting is as much of a cre-

ative challenge as is any segment

of the building and construction

industry, and far bigger.

The extraordinary increase

in the amount of stores being

launched or renovated in the past

two years offers business opportu-

nities for design professionals of a

like of which has never been seen.

Finally, the attention to

energy use restrictions is making

retail owners think seriously—not

only about the amount of energy

that lighting accounts for and what

it costs—but what the lighting looks

like on the sales fl oor and what it

does for the products on display.

Just the sampling of designs

featured, shows the great deal of

creativity on the part of designers

and manufacturers to understand

the role of lighting in motivating

retail purchasing, across price

points. Clearly, retail lighting is at

the forefront of practical applica-

tions of augmenting the light-

ing function as art and calling

attention to lighting in the built

environment around the world as

part of enhancing everyday living

The Challenge:Like many older gaming facilities, the Coeur d’Alene Tribal Resort, located near the town of Worley in the northern portion of the Idaho panhandle, was in need of expansion. The casino’s manage-ment was faced with the task of adding something new in order to compete as a true destination, with attractions for non-gamers, and to increase its overall appeal. The goal of the tribe was to cre-ate a complete resort experience, integrating elements and sym-bols of their tribal culture and beautiful natural landscape with modern design trends and light-ing technology. The challenge, therefore, was to create a dra-matic new facility with improved amenities while respecting the tribe’s concern about their impact on the environment.

The Solution:The result is a 110,000-sq.-ft, LEED Gold-certifi ed addition comprised of 100 four-star guest rooms, two restaurants, a lounge, a spa, and the “skycatcher,” a circulation element that connects the new elements of the complex with the existing gaming space and provides a gathering space with sweeping views of the roll-ing hills of the Idaho landscape.


Vision Quest

When it came to approaching

how to illuminate the expansion

and renovation of the Coeur

d’Alene resort, which included an

existing casino, lighting designer

Jill Cody had a specifi c vision:

It would not be Las Vegas-style

glitz, rather, she wanted to inte-

grate the lighting as an addi-

tional layer to help tell the tribal

story and enhance the warmth

usually associated with hospital-

ity settings in a way that harmo-

nized with the rustic elegance of

the materials used. “This meant

the careful illumination of mate-

rials and surfaces, the creation

of contrast to enhance the mood,

and respect and reference to

tribal culture and tradition,” says

Cody.

Since the resort sits 30

miles outside of the eponymous

northern Idaho town, there is no

light pollution in the night skies,

allowing lighting to subtly create

the resort’s environment.

“We were trying to create

an exciting environment, yet not

overwhelm the darkness. We

did not light the exteriors of the

buildings, but went for subtle

light from the interior rather

than Las Vegas-style sparkle,”

says the designer.

For example, bridging the old

building to the new is a courtyard

dubbed the Night Sky Lounge

(above). To spice it up, a blue

acrylic wall, that masks a wall on

the old building, is backlit with

LED puck lights placed randomly

for the effect of a starlit night

with softly twinkling stars. A

blackened and pre-rusted steel.

“It is a very Northwestern ma-

terials palette,” explains Cody,

who wanted to make sure the

materials got their due through

the lighting.

She decided LED RGB was

the appropriate medium for story

telling. “We used color-changing

for three major design elements:

Eagle Staff Tower, the Feather

Bench, and the Skycatcher fl oor.

Color sequences were created

with references to tribal culture,

such as costumes, the night sky,

“It makes you feel as if you are

doing this for a reason, and

makes it amazingly meaningful.

You feel connected to your work

as a lighting designer at the end

of a very long project.”

Color Correction

Color changing was also a big

part of the project as Cody

wanted to match up with archi-

tect Mithun’s choice of building

materials, which she says has

rural overtones, with an empha-

sis on wood, water and stone, plus

and Lake Coeur d’Alene, itself,

the tribe’s ancestral home. These

three color-changing elements

are coordinated with one another

and run on a schedule that tells a

different story each night of the

week,” notes Cody.

The elements are coordi-

nated with the same color at the

same time, which according to

Cody, took complex program-

ming to achieve, with different

palettes to evoke different tribal

references, from the color of their

costumes to a rainbow effect.

ELEMENTALWater is a critical element to the

tribe, as they once lived along the

shores of Lake Coeur d’Alene. The

resin waterfall is backlit with blue

LED to emphasize the element

of water. In fact, the winding

luminous line points directly to

the lake.

THE RIGHT TONENatural colors and elements, in-

cluding wood, were also important

components within the project. In

the facility’s new restaurant, The

Steakhouse, lighting designer Jill

Cody noted there was a particular

emphasis to get the coloration

of the wood right in the dining

establishment.


Eagle Staff Tower

One of the most visible tribal-

inspired elements is Eagle

Staff Tower, a 105-ft.-tall iconic

column of Corten pre-rusted

steel with slots, or lens-covered

openings, that allow the color-

changing light to shine through

as a welcome beacon at night (its

base is visible in the upper right

background of the image to the

right). Each slot can be a differ-

ent color via signage-grade LEDs.

Red beads that adorn the tower

are lit from wells in the ground.

The Water Feature

Approaching the entry to the

resort, a winding, luminous resin

water feature guides guests to

the resort’s front door. Linear

LED fi xtures backlight the resin

and highlight a Corten steel wall

that runs behind the water.

“The tribe used to have land

on Lake Coeur d’Alene, and water

is very important to them,” says

Cody. “The line of light on the

water feature points to the lake.”

In fact, the light shines

through a transparent blue resin

material, using Hydrel fi xtures.

The water is also lit from the

front as well with Boca Flasher

linear submersible LED fi xtures

that reveal the movement of the

water. The light on the water fea-

ture is all white; as Cody points

out, “because the resin is blue,

there is no reason to change

colors on it. I really like the blue

against the rusted color of the

Corten steel.”

The Steakhouse

In the new restaurant, The

Steakhouse, Cody used LED

fi xtures where appropriate, as

well as dimmed incandescent

lamps to meet a one-footcandle

light level.

“The color quality of the

light was really important with

all the wood in the space,” notes

Cody, who used MR16 downlights

on low-voltage tracks in the ceil-

TRANSITIONDaylight is a prominent element

coming into the facility, particu-

larly its “Skycatcher” area. The

casino, however, is much darker

and a transition had to be created

to link the two and create way-

fi nding for casino patrons.

MATCH ON ACTION In the entry there is also an art

installation with abstract time-

lapse photos of tribal members in

traditional costumes. The images

are on laminated glass with a

sandwiched fi lm layer. “The idea

was to take tribal stories and

weave them into the project in

unique ways,” says Cody. “It was

a real education for the design

team; we learned a lot about the

tribe and their history.” Colored

LED was employed in the fl oor

to evoke the legend of “Coyote

Scratches” and match up with the

colors in the art feature.

ing. During the day, a large glass

wall allows a lot of natural light

to enter the space, and low light

levels near the glass minimize

refl ections and allow a clear view

to native plantings outside.

“There is a different quality

to the light during the day,” Cody

adds, noting that the lighting

in the restaurant is actually

bumped up during the day to

make sure the back corner of the

room seems brighter, and to bal-

ance the room.

She also used Winona linear

LED kick-lights and LumenPulse

cove lighting to add accents to

the wood ceiling.

The Casino Entry

The theme of color-changing

light continues at the casino

entry, creating a transition zone

between the bright, day-lit area

of the “skycatcher “and the much

darker gaming fl oor.

In the “skycatcher”area (be-

low, left), a blend ceramic metal

halide uplight and downlight

creates quiet gathering zones to

balance a more active circulation

zone. Uplights and downlights

are turned off during the day in

this well-daylit space.

But in this space, LED

comes alive in communicating

another tribal reference: the

legend of “Coyote Scratches” in

the landscape, which are evoked

in the space with glowing LED

tiles (Lightwild) that reach out

into the “skycatcher” to hint at

the excitement inside the casino.

“We wanted to tell people that

something existed back there,”

says Cody.


In the entry there is also

an art installation with abstract

time-lapse photos of tribal mem-

bers in traditional costumes.

The images are on laminated

glass with a sandwiched fi lm

layer. “The idea was to take tribal

stories and weave them into the

project in unique ways. It was

a real education for the design

team; we learned a lot about the

tribe and their history,” Cody

notes.

The Spa

Adding to the allure of the resort

is a spa where the design is

defi ned by a large stone wall,

uplit with incandescent sources,

which Cody selected for “good

dimming control,” although she

adds it is “unusual” to use incan-

descent on a project at this scale

these days.

The downlighting is a mix

of MR16 and fl uorescent. “We

started designing this project

in 2009. There is a wider choice

of LED fi xtures to choose from

today, but I’m not sure we could

have afforded them for almost

1,000 downlights on this project.

The spa also features a glass

panel that sits atop the stone

wall, allowing light to splash into

the adjoining pool, once again

emphasizing the importance of

daylighting in this project.

The Courtyards

Beyond the centerpiece blue

wall, another signature design

element in one of the outdoor

courtyards is a wooden bench

evoking a feather.

CONNECTED TO THE LAND The tribe carries a deep connec-

tion to the land and the resort

site sits at the confl uence of two

habitat types: grassy hills and a

forest. As a result, exterior views

were important to the architec-

ture. Low light levels near the

glass minimize refl ections and

interior lighting is warm and quiet

to impart an ambiance of refl ec-

tion and healing.


The bench features a center

spine of Corten steel, echoing the

materials palette used else-

where. Color-changing Philips

Color Kinetics EW Powercore

LEDs under the the feather

bench give it the appearance of

fl oating on a cloud of light.

“The bench is designed like

an eagle feather, another impor-

tant element of tribal culture,”

says Cody. “The Corten center of

the feather is illuminated with

linear Lightwild white light that

does not change.“

All colored light at the bench

changes at the same time, so the

experience is different from the

tower and Skycatcher, where

multiple colors are visible at a

given time.

“Instead, the sequence of

color takes place over time,” says

Cody.•

TRIPLE AXEL LANDED: SUSTAINABILITY AT A REASONABLE COST& IMPROVED LIGHTING

ERNST & YOUNG OFFICESNew York City

ABOVE: The retrofit dropped wattage consumed by about 40 watts per sq. ft., which cut the office’s total lighting consumption in half. Between energy savings and maintenance savings, the company will save about $1 million annually. A mix of sources were employed, almost a quarter of those being LED. “We didn’t set out to do an LED retrofit, it just evolved that way,” says Lighting designer Stephen Margulies of One Lux Studio.


The professional services firm of Ernst &

Young believes in corporate sustainability.

In fact, the organization hopes to have half it’s

employees in LEED-certified spaces by 2013. But

being accountants, they want to make sure any

such measures reflect financial soundness. A

recent, significantly LED lighting retrofit of the

company’s Manhattan offices proved a fruitful

marriage of both goals—oh with a third benefit of

greatly improving the lighting environment.

As part of their sustainability initiatives,

the company regularly consults energy special-

ist Jim Schwartz of JAS Consulting to keep tabs

on their buildings with an eye toward better

efficiencies where and when possible. In the

course of such due diligence, about three years

ago, Schwartz had a casual conversation about

the company’s Times Square offices with lighting

designer Stephen Margulies of One Lux Studio.

As Ernst & Young was preparing to enter a

new lease on the space they wished to evaluate

a few things, particularly lighting. Following a

walkthrough of the 32 floors of offices, Schwartz

knew “instantly” that “millions of watts” could

be pulled out of the space. That being said, the

consultants also wished to be sensitive to the

original lighting design created by Gensler and

Susan Brady, which was done about 10 years

prior. At the time, the emphasis on the lighting

design was more on the aesthetic, according to

Margulies, and the design was indeed “fantastic,”

but not so efficient from an energy perspective.

“There were lots of MR-16s and lots of mainte-

nance issues,” says the lighting designer.

Not only were there a lot of inefficient

sources—many with old ballasts—but the offices

were generally overlit. In some places they found

light levels as high as 80 footcandles. “We started

This was of great relief to Margulies as

he wished to drop light levels by almost half

in many spaces. Another aspect the designer

is particularly proud of is the fact that all the

retrofitted lamps were UL certified—something

that surprised Ernst & Young’s insurance carrier.

According to Margulies, this due diligence was

important to the design team to not only ensure

safety, but make sure that warranties would not

be voided. This was especially significant as the

project was being delivered turnkey by Philips

Lightolier Energy Service Group, who was not

only supplying product, but providing financing

and a 5-year warranty on all of the products.

As a result of the retrofit, maintenance

costs dropped from $16,500 annually to $3,000.

Combined with the energy savings, this yields a

3.5-year payback. “It all goes back to cost benefit,”

says Margulies.

Philips, who has a long-term relationship

with Ernst & Young, took on the project as it fits

well with their corporate philosophy. CEO of the

Lighting Division, Zia Efeketar notes Philips saw

the project as great example of the “triple axis”

that needs to intersect: the ability to meet sus-

tainability goals; improved energy efficiency at a

reasonable cost; and improved lighting quality.

thinking this was more than a light bulb change,”

says Margulies. The goal became to reduce the

overall power density from roughly 200 watts

per sq. ft., to as low as they dared dream.

That said, both he and Schwartz wanted to

preserve as much of the original design as pos-

sible, including retaining as many of the existing

fixtures as possible. And because of the technol-

ogy available today, notably LED, the pair felt

confident this was not only achievable, but that

they could maintain, even improve the quality of

the lighting environment, particularly in private

offices. “You can’t underestimate lighting qual-

ity,” says Margulies. “We took the non-daylight

spaces and made them great.”

Where possible, the consultants simply

replaced source for source. Where not possible,

the team refitted existing fixtures with new

sources. In some cases, new fixtures were cre-

ated. The team proceeded with mock ups, many

with much lower light levels. To get feedback,

they actually had Ernst & Young employees

evaluate and comment upon the look and feel of

the space.

“I remember it was a rainy Saturday, and

many of them didn’t even notice any difference,

which we took as a compliment,” says Schwartz.

How about first cost? Efeketar says the

project was viewed by the client as an invest-

ment. “So from the beginning, ROI was on the

table and we had to figure out what the payback

had to be—to make that happen, we had to go

with an integrated system,” says Efeketar.

This was an important decision for Ernst

& Young—or any client—as moving away from

decisions based completely on initial cost, to one

that’s a calculation of total cost of ownership,

forces the client to establish “X” return from

the beginning, so the team knows exactly what

needs to be done, and at what cost. “The ultimate

goal is reaching that ROI,” says Efeketar.

Will this project have a domino effect? “The

train has left the station,” says Efeketar. “I feel it

will be a positive endorsement, especially for a

public auditor of its stature. It certainly begs the

question: Why not you [other corporate entities]?”

Regardless, Efeketar says the foundation

for such retrofits has been laid, and it’s a solid

platform, granted the sums must add up.

“There are clearly economic uncertainties

to overcome. That’s where we’re hoping our

internal financing will help,” says Efeketar. “But

if you can’t achieve payback in a period of 18

months to five years, it’s not a proposition.”•

SMOOTH TRANSITIONThe new lighting system reduces annual lighting energy consumption by 54%. More than 3,000 high-wattage CFLs and MR16s were replaced with 20-watt LEDs. Elsewhere, existing fixtures were refit with LED components for greater ef-ficiency. In all, the lighting consultants “touched” nearly 20,000 fixtures—a fourth of that with LED solutions.

THE CHALLENGE:Pull as many watts as feasible out of the client’s

650,000-sq.-ft., nearly 6,000-employee offi ce space

while preserving as much of the space’s original

lighting design as possible.

THE SOLUTION:Three strategies were emploed:

• More effi cient retrofi t lamp sources were

installed where possible—notably among the

existing MR16 and CFL lamps

• As many existing fi xture/luminaires were

retained as possible, but refi t with more effi cient

light source components

• Replace fi xtures where necessary to

accommodate more effi cient sources

As a result, the design cut lighting consumption in half from its whopping original 6.2 million kWh per year, simultaneously reducing CO2 emissions by roughly 2 million pounds.

wide objet ’d’art. A winner of Cooper’s Source

Award earlier this year, the spectacularly illumi-

nated structure resides, where else, but in the

Land of Lights, Las Vegas, where the bar’s draw

is an experience that bathes guests in crystal-

lized light.

Upon entering the hotel’s casino, opulent

strands of crystals drip dramatically from the

ceiling; their luxurious luster beckons gamblers

to pay a visit to one of the fi ve bars and lounges

that are seemingly suspended inside the crystal-

line strands.

The lighting design team from New York-

based Focus Lighting, along with architect the

Rockwell Group, created the unmistakable

illusion of a single internally lit chandelier,

and supplements it with lighting techniques to

achieve sparkle in every delicate strand. With

technical expertise and a larger-than-life mock-

up, the team deliberately aimed light at each of

the kinetic chandelier’s seven million crystals.

Their research helped to predict the precise

angle at which each crystal would need to be il-

luminated to achieve the maximum sparkle with

minimum headaches—that is, provide a dramatic

display that is neither nauseating nor glaring to

the casino’s guests.

Being nearly 50-ft. high, the chandelier is

surrounded by a concourse or casino circula-

tion on two levels. It also contains fi ve separate

bars and lounges that seem to hover within the

ethereal space.

The design team chose Cooper Lumière 203

ETHEREAL BEAUTYThrough a combination of color motion and controlled sparkle, guests are able to experience vastly different moods as the chandelier transitions from day to night. The three-story core features 700 crisp, white dimmable LEDs mounted within a sparkling liquor tower and spiral glass stairs, creating a strong contrast to colors on the crystal swags.

multi-head fi xtures are installed vertically in the

perimeter soffi ts of the fl oating fl oors to provide

multiple points of warm, beautiful front light.

Each lighting position was studied in plan and

section and then mocked-up on site to review

precise aiming angles.

A dimmer switch and controls program

transitions the chandelier from daytime to a

night-time lighting scene that intensifi es the

drama throughout the evening hours. As part

of the evening program, light, color washes and

abstract images are projected onto the vertical

crystal drapes, which are supplemented by an

additional layer of vinyl-coated aircraft wire.

Stairway to Heaven?

You’ve heard of a champagne fountain, but how

about a liquor chandelier? A solid light source

runs through the core of the bar (above), which

includes the staircase used to circulate through-

out the three fl oors of the casino. The three-

story illuminated inner core features 700 crisp

white dimmable LEDs mounted within a spar-

kling glass tower that acts as a liquor display

surrounded by a spiraling glass staircase.

Don’t Mock the Mock

A year prior to the chandelier’s erection, Gregory

and the Focus team constructed a full-size, 20-ft.

tall mockup of an entire section of the chan-

delier. The mockup allowed the design team to

analyze the appearance of the lighting on the

crystal from both the outside and inside of the

chandelier. Furthermore, the mockup provided

the opportunity for adjustments in factors such

as lamp type, color, and fi xture positions and

quantities. For example, the effort allowed the

Focus design team to determine that there was a

need for an additional layer of halogen uplights.

It also provided them a substantive mechanism

to demonstrate to the client, that there, indeed,

was a need for 150 of the Lumiere 203s.

For those guests who enjoy an intimate

drink with the barkeep, several softly illumi-

nated enclaves provide a cozy atmosphere with

halogen downlights to give warmth, while a

custom chandelier reinforces the theme.

Visionaries?

Like everything in Vegas, the over-the-top

crystal distraction would have guests feeling like

Alice in Wonderland, but for the expert vision of

Focus Lighting, which has made it into a fi rst-

class spectacle.•

When a new technology emerges, there is a need for an extraordinary

educational effort to create viable customers for it. Since customers

experience technology progressively over time, the demand for

advancing education grows to serve a broadening range of need from

fundamental basics to focused specialty information. Whether

provided as a presentation at a conference, offered on a YouTube

video, or included in sales presentations, there are many opportunities

to participate in building customer knowledge. However, there are a

few fundamental rules that need to be adhered to that separate actual

customer education from simplistic company promotional efforts:

1) Know the Audience

Educational content that has no target audience in mind often

educates no one. Keeping the audience in mind provides guidance

as to what needs to be included, and at what level. If you don’t know

the customer, seek assistance from someone who does. Keep in mind

that the customer is an expert within their own universe, critical of

outsider error that reduces credibility. For example, failing to present

color and uniformity performance metrics as a higher priority than

pure energy saving to interior designers is a failure to understand the

daily demands made on this customer.

2) Present Information Objectively

Objectivity is the difference between promotional marketing presenta-

tions and actual education. Even when educational efforts are pursued

as part of a marketing program, erasing company bias when delivering

information is critical, even if some points in that content are counter

to company messaging. Objectivity includes presenting advantages

and implications of approaches, without distortion. For example,

presenting AC LED light sources as a favorable approach, based solely

on elimination of electronic components without covering fl ickerissues

and possible impact on effi ciency, is a failure to present objectively.

Further, educational programs designed to fi ll space, or masquerade

product presentations as “educational” fail the objectivity test.

3) Provide Contrasting Views or Approaches Positively

One of the most powerful tools for an educator is to present a problem

with several contrasting solutions. The depth of information presented

adds to intrigue and engages the recipients to think about the topic in

greater depth. For example, presenting a review of LED retrofi t lamps

to prove the inferiority of halogen lamps is less valuable than case

studies showing direct comparison of LED and conventional products

applied to lighting restaurants, covering the pros and cons of each.

4) Simplify the Scope and Expand the Detail

There is a measurable difference in value delivered between attempts

to cover a wide range of topics in shallow strokes and focusing on a

few specifi c items in greater depth. That does not mean expanding

complexity by delivering scientifi c data, it means tailoring the

information presented in context to the customer’s needs with depth

of information applicable to making practical decisions.

For example, retail lighting customers really don’t need to know—or

care about—the specifi cs of semi-conductor production yields, but do

need to know how LED color impacts appearance of products

displayed.

5) Lead Recipients through the Topic in Steps

Educational programs should be formatted in a linear, step-by-step

progression. This includes the briefest possible summary of basic infor-

mation, building more and more depth as the program is completed.

The balance of depth of information delivered at each step is an art

that requires careful planning and review. For example, presenting the

basics of human color perception and sensitivity, leading to a summary

of the issues of color metrics used for light sources, provides a progres-

sion of information that builds relevant understanding.

Evolve, Refresh

As technologies grow in familiarity, so do the needs of educational

support. While the very earliest phases of deployment demands basic

technical education, more mature customers will fi nd this content

redundant. This evolution of need provides many opportunities to

remain engaged in education by evolving new content. The key to

successful educational effort is to continually create fresh materials

to meet the growing needs of customers. The reward for participat-

ing as an educator, especially when approached with an objective eye

on customer needs, is growth of understanding in the market as a

whole. In the end, educated customers are more likely to take a risk on

an emerging technology, earlier, than those who are left confused by

marketing noise alone. •

THE WHITE PAGES

Over the past decade, LED lighting technology has continued to evolve

to meet the demands of today’s commercial market, providing users

with high-quality illumination, superior energy effi ciency, lower opera-

tional costs, lower maintenance costs and long service life.

As LED dies and packages continue to evolve, LED luminaires have

improved as well, which has led to a signifi cant increase in adoption

by engineers, architects and lighting designers. However, little has

been done by manufacturers of luminaires to maximize the benefi ts

of this improved technology. Specifi cally, the approach to fi xture and

optical design has not been modifi ed to take full advantage of the new

properties that exist with LED sources. As a result, there are still many

untapped benefi ts to LED lighting that can provide new options and

opportunities for lighting specifi ers.

Hyperbola: A New Approach for a Directional Source

Traditional light sources such as incandescent, CFL and HID lamps are

omni-directional sources, producing light in all directions. In order to

redirect the light down and out of the aperture of a recessed fi xture, a

parabolic refl ector is the most effective shape to maximize effi ciency.

However, due to the uni-directional nature of LED sources, utilizing

parabolic refl ectors has proven diffi cult in terms of minimizing glare

and achieving a uniform beam spread on the work plane. As a result,

additional diffusion is typically required when using a parabolic

refl ector in order to spread the light to achieve the uniform distribu-

tion that lighting designers and commercial building architects desire.

Prompted by the demand for low-glare, high-effi ciency LED

luminaires, engineers conducted extensive research and testing,

and discovered that changing the overall shape of the refl ector from

parabolic to hyperbolic provides superior light distribution control for

LED sources. Why? The inherent nature of the hyperbolic shape itself,

which refl ects and spreads light similar to a convex lens—as opposed

to focusing the light—is the reason.

Due to the geometry of the hyperbolic curve, there is no source

image in the refl ector as any refl ected light is directed down toward

the target work plane. By eliminating the need to diffuse the light with

a lens and redirecting the light toward the work plane, the effi cacy of

the luminaire can increase as much as 35%.

In addition, the hyperbolic surface allows the refl ector to block

the light that would be incident on the lower portion of the refl ector,

casting a shadow that dramatically reduces the aperture brightness.

The hyperbolic refl ector shape also reduces the amount of light-source

regression required for glare control by increasing the shielding angle,

thereby reducing the profi le of the downlight housing and permitting it

to fi t in a wide variety of commercial construction applications where

lighting designers are seeking a more natural lighting atmosphere. It

also allows for a more "silent" ceiling, a new architectural buzz word

referring to a simpler ceiling plane, where fi xtures in a space are not

as noticeable or conspicuous.

While parabolic refl ectors are still a high-quality option to

optimize light distribution in commercial applications that require a

more traditional appearance, the newer hyperbolic shapes allow

designers, architects and facilities managers more versatility and

control over the illumination characteristics of an application.

In addition to virtually glare-free, “silent” ceiling effect the

hyperbolic shape provides in commercial spaces, the unique curvature

also produces additional benefi ts to users such as:

• Increased lumens: The hyperbolic shape provides up to 35%

more lumens by directing all light at the target work plane

and eliminating the need for additional diffusing.

• Higher effi cacy: Up to 35% more lumens per watt.

• Increased application fl exibility: Increased lumens to

accommodate higher ceiling heights and better control of

the light allow multiple beam spreads.

• Unique aesthetics: Extremely low brightness

• Very large lumen packages from very small, and silent,

apertures

A New Option for Recessed LED Illumination

With the continued innovation of LED sources and the discovery of the

benefi ts a hyperbolic refl ector can provide in commercial applications,

lighting designers, architects and building owners now have another

option to consider when looking to create the ideal, aesthetic and

energy effi cient environment for building occupants. •

LETTERS TO THE EDITOR:RGB OVER THE EDGE, BUT DOESN’T HAVE TO BE

Just read your LED Insights [from the September issue] and can’t agree more. RGB, since becoming “leading edge,” has gone to “over the edge” in usage. It is often just plain misused in too many applications. That said, we are presently involved in using color changeable LED in a major residential pool and grotto system. In carefully mixing white, and control of the RGB, we, hopefully, will create pools with beautiful effects presently not known. The waterfalls are intentionally always left white so that there is no chance that own-ers can turn the “scene” into visual chaos. I am excited to see intense red water with white falls and white star effects randomly placed in the bottom of the lazy river along with fiber optic delivered LED white lights randomly placed in the ceiling of a rough stone ceiling. Rather than being a “starry sky,” they are to emulate the tiny eyes of unknown underground creatures. So, RGB, if planned well, can be good.

EDITORIAL PREVIEW:IN THE JANUARY ISSUE: We take a look at how SSL is being applied in office environments as general ambi-ent lighting. We’ll stick with our focus on interiors, with a profile on lobby/atrium of the Kansas City Marriott by Bruce Yarnell. Kevin Willmorth addresses proprietary controls issues associated with dimming LED. On the project front, we’ll showcase cool white lighting using exotic fixtures in the Sagafredo Cafe In Greenwich Village, New York. Across the Atlantic, we go inside a storage tank for a truly inspirational retrofit and re-use project. Also, new products, and of course, news.

ABOUT THE AUTHOR:

Kevin Willmorth, a lighting expert and fi xture designer,

has been instrumental in helping create a vision and

mission statement for Architectural SSL.

Let us observe a moment to refl ect on the light of the tungsten register has put upon us: Soon there will be a time when we have only memories of its warm yellow, color-distorting, and energy-hogging glow. So long old friend.

Requiem for theTungsten Resister Light

We have come to a turning point in lighting

where solid-state is poised to displace a tech-

nology we have all come to love—the tungsten

resister light, better known as the incandescent

and halogen lamp. While there remains a strong

bond to these heat sources masquerading as light

sources, the writing is on the wall. The use of

tungsten resistance technology is facing attack

by a superior technology armed to take it down,

and it’s got a silly name, and that is LED.

If only there was a way to make halogen

lamp much more effi cient and long lived. These

simple lamps asked only to be fed a fl ow of cur-

rent, AC or DC, modulated or not, and they lit up

gladly for their brief, power-thirsty life. They

could stand most any environment, hot or cold,

dim with the cheapest dimmers available and

generate a nice warm color, as long as they were

not knocked around. They also have the dignity

to just burn out when they are done with life, the

clearest indication of maintenance need.

Comparatively, LEDs are fussy about the

power you feed them, complain when over-

heated and are easily killed when mis-wired. The

slow death by lumen depreciation is just more

whimpering. And, what’s with all that electronic

gadgetry?—The entourage is unbecoming.

Halogen lamps have existed as long as they

have because they were relevant in compari-

son to other light sources available until just

recently. Fluorescent lamps are bulky and ugly,

impossible to control optically and require big

support gear. HID, Induction and CFL are awful

technologies, period. They are inelegant, hard

to design around, and generate barely tolerable

light qualities. One uses them because of practi-

cal reasons, not because they are great products.

If the world were lighted by tungsten resisters,

the earth would now be covered in a foot deep

layer of spent lamps, the economy destroyed, and

the atmosphere choked with the emissions of

millions of coal fi re plants.

Alas, LEDs bring with them the asset of tiny

kernels of light, halogen’s most precious feature.

Yet LED brings with it fewer liabilities, and an

arsenal of new values beyond the reach of the

obsolete. They deliver scalable light and form,

new optical potential and inherent directionality

coupled to a dizzying array of colors—delivered

with the kill shot of long life and energy

effi ciency. The only comfort one might capture

from the demise of such a loyal friend is that

tungsten resister sources are but the lowest of

hanging fruit. On the branches above are the

CFL, then HID, and linear fl uorescent. They can

hide for some time, but will eventually be pruned

to niche applications beyond the interest or

reach of the coming solid-state swarm. High

power LED, plasma, OLED, and sources yet to

be released from sequestration by non-disclo-

sure agreements, indicate a future essentially

absent of tungsten resisters.

Many will not miss fl uorescent lamps

when they are gone and most can’t wait to

see CFL killed off altogether. The eventual

absence of HID will not cause a second thought

to anyone. However, we will always miss the

simplicity of the halogen lamp. Even though

each individual lamp’s existence is more but a

fl ashbulb on the time line of lighting history,

the technology brought many of us great joy.

For tungsten resister lovers everywhere,

solace can be taken from the fact that LED

intrusion is being slowed by short-sighted

marketers and metrics engineers, who have

yet to discover the secret path to deliver the

true value of solid-state, which will be the fatal

blow—much like the smart phone ended to

popularity of the Princess phone, and digital

imagery devastated the instant camera. For,

as long as the LED is delivered in ways that

remind us of how much we love the tungsten

light source, we will never truly wean our-

selves from its magic embrace.•
