LIrr is not the most imporlant {actor in the cost ofiighl, Any lamp manufaciurer can increase lhe averagelile oI an incandescent lamp. This can only be done,however, by decreasing the lighl produced or increas-ing lhe currenl consumed.

Short Lile means More Light. Long LiIe means LessLight, The mosl economical lamp life is arrived at bylaking into consideralion all oI the cosls involved.These are primarily the cost of the lamp and lhe coslof lhe current, The designed lives o{ WesiinghouseMazda lamps are chosen to obtain minimum lightingcosls when the laclors oI lamp replacement and over-head charges are also considered.

Engineers and economists have studied the various

types oI lamps and service and have deiermined themosl economical and salislaclory lile Ior each. TheseIives in our slandard line oI lamps range Irom a frac-lion of a second for the photo{lash lamp 1o 2,000 hoursfor iraffic signal and streei lighiing lamps.

LIGHT OUTPUT MAITTAIITIDDTHROUGHOUT I.I[DTo maintain light output lhroughout lhe life of a lamprequires greal care in manulaclule and selection ofraw maledals. The effect ol lhe crystal slruclure ofIilame wire on lamp perlormance under varyingcondilions makes it necessary lo selecl the filamentwire lrom a dozen dillerenl groups.

Vacuum gauges which measure gas Pressure lowithin lhirty-one billionlhs oI an atmosphere ale usedto check exhaust machines.One drop of moislure distributed within 100,000

lamps is sufficienl lo cause excessive blackening andlhereby reduce the elliciency o{ all these lamps byl0 per cent. To guard againsl moisture and olher im-purilies, lilamenl wire is stored in an air-condiiionedroom and hermelically sealed gas lines are used ioconducl the gas from slorage lanks 1o the lamp makingmachines. In addition to careful handling ol clean lampbulbs, lhey are heated al exhausl by direcl gas llame1o drive oll all impurities and moislure.

This machinery is theullimate in precision and {unctions under the watchfulguidance ol highly lraited operators, mechanics, andengineers.

GENERAL LIGHTING SERVICE-rro, r1s and r2o vortsGENERAL LIGHTING SERVICE lamps lulfill 65per cent ol the lamp requirements {or ordinary usesin homes, stores, ol{ices, schools, factories and lhelike. These lamps will operate in any posilion o{burning, but the liqht maintenance, particularly inIamps of higher wattage sizes, is best when lampsare burned vertically base up. The data on light(lurnen) mainlenance given in the lechnical summaryapply to this burning position only.INSIDE-FROSTED DINISH The liqht absorbedby inside lrosting is so negligible (the lumen output israted the same as {or clear lamps) that these lampsare recommended for most general lighting purposesto provide added dillusion and. in the case of indirectlighting equipment, to eliminate siriations and harshshadow e{lects.

Approximate Screw Base

CLEAR fINISH-CIear bulb lamps are satisfactoryfor use in adequately shielded rellectors or diffusingequipment which protect the eyes lrom the irritatingel{ecls and inel{iciency which glare produces. Theyare used also in {loodlighting and miscellaneousspecial applications requiring reasonably accuratecontlol of light.WHITE BOWL FINISH-The lisht output oI whitebowl lamps is approximately 3 per cent less thanthat of clear or inside-{rosted lamps. They should beburned base up only and are recommended {or usein open-type equipmenl such as the RLM Domereflector to improve the quality o{ illumination byminimizing direct glare, reflected glare and deepshadows. These {actors, as well as adequate amountof liqht, deterrnine the ef{ectiveness oi the illuminatior.

In many instances of colorrendition their use gives sullicient color correclionto be o{ considerable advantage over the warmertones ol unmodilied liqht. For example, they areused in many industrial applications, particularly inlocal lightinq units for sewing machines and lorspecial assembly and inspection processes. Again,the light blends well with natural dayliqht; in {act,in many case6 it is about the same color as the day-

liqht which one gets indoors, taking into accountthe prevalence of warm tones in window shades, wallsand hangings. For this reason the use of daylightlamps in offices, stores and other commercial interiorswill be Iound to correct an unsatis{actory mixtureof ordinary a ilicial light and inadequate dayliqht-The next larger size o{ lamp will be required toproduce approximately the same illumination valueas computed {or a clear or inside-{rosted lamp o{ agiven size.

MAZDATHREE-LITE I.AMPStlO, tls and 120 Volts

I MAZDA Three-Lite lamps, with two separate fila-ments in a single bulb, have introduced a newflexibility in liqhting, since each Iilament of di{{erenty/attage may be lighted separately or in combinationwith the other to produce three levels of illumination.Thus with a single lamp, lhe user can adjust theillumination to suit the needs the lower wattage Ior

decoralive and casual use, an inlermediate step, andup to Jull brilliancy lor lull utility where seeingrequirements dictate higher levels ol illumination.These lamps are particularly applicable to the

newer type study and reading lamps and lo indirecland semi-indirect {loor lamps. The 100 200-300-watt size is designed for base-down burning and isadaptable to wall urns and any use where lamps arenormally operated in base-down position. The 50-I0O-150-watt lamp is designed to burn in anyposition.

The lamps are inside frosted to assure compleledifiusion and to avoid uneven light streaks and harshIines of culoff on ceiling and sidewalls when used inindirect poriabJes a nd wall urns.
