LED Lighting,
Capabilities Today
and Tomorrow
• The most important citizens in the USA are our men and women serving currently and the Vets that went before them!
Learning Objectives
Questions??
1. There have been at least 15 TLED recalls worldwide since 2013?
2. Haitz’s Law dictates how many LED products will be available in 2016?
3. LIFI might replace WIFI soon?
4. LED is more efficient in high Kelvin temperatures?
Sustainability Defined
Actual NO!, Really
Haitz’s Law
• Every 10 years, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light.
• Similar to Moore's law, which states that the number of transistors in a given integrated circuit doubles every 18 to 24 month, i.e. computers.
Where is LED today, tomorrow?
What about cost?
Is there any opportunity out there?
Highbay Areas?
Albeo, 137 lm/w Orion, 179 lm/w
Linear Fixtures
Old, 6L, T8. 192 watts, 135-170 FC
NEW, LED retrofit, 38 watts, 130-170 FC
Are TLEDs the answer? NO!!!
• Generator sparks recently killed all 3,000 driver integrated tubes in a hospital!
• Reusing the ballasts, ok, but existing ballasts MUST be replaced.
• Recalls are now over 15 since 2013, including 2 well-known lighting companies.
• New fixtures, anything good above your ceiling??
• NO rebates with Title 24 when the sockets are re-used. No real retrofit would ever not replace the sockets!
A Proud moment in TLED history.
Economics?
• Major Retailer with over 18,000 locations
• Must maintain FC levels and reduce energy
• Moved from 133 fixtures to 81
• First cost moved up approximately 25%
• 10 year LCCA, $43,300 versus 37,400, 13.6% better
• Energy consumption reduced by 16.9%

Future
• Costs continue to drop, efficiency improves. • Manufacturers consolidate and dramatically change. • LIFI, visual light communication, instead of WIFI,
digitizing light. • UV lighting to disinfect anything you touch, imagine
killing Legionella, Merca at the sink! • Controls on light poles, including tracking you! Big
Brother will be watching! • New TM-30 to assign CRI valuations. • IoT • POE, Power Over Ethernet
Future
• Digital Ceiling
• Light fixtures are everywhere! They won’t be “dumb” anymore
• Sensors to monitor and control everything, temperature, air quality, security, everything!
• Cost savings, no more camera systems, HVAC controls, intercom systems. ALL IN ONE, lighting.
• Individualized, human-centric comfort outside of human involvement.
