I More Light for Less Money. Higher light output (up tothree times that of incandescent lamps) for the same wattageconsumption means lower operating costs' Initial installa-tion cost is lower too because you need fewer lamps andfixtures and less rewiring'2 No Obsolescence. Increases in lamp efficiency are accom-plished without changing lamp operating characteristics.This permits users to enjoy the full benefits of new, im-proved mercury lighting without the expense and nuisanceof rewiring, changing older fixtures or replacing ballasts.3 On the Job Under All Kinds of Conditions. Mercury lampsoperate indoors and out, in subfreezing or mid-summerweather - even under conditions that might cut fluorescentoutput by half.

Sylvania Mercury Lamps not only givemore initial light output for the same power, but maintainthe highest light output too. Even at 16'000 hours, SylvaniaMercury Lamps still give up to 87/e of their initial lightoutput.6 Compact, Controllable. Mercury lamps provide a power-ful, pencil-thin light source that allows precise directionalcontrol for best lighting effect, so there's little wastedillumination.7 Reduced Relamping Costs. Because mercury life is so long,and its lumen maintenance so high, servicing and grouprelamping periods are greatly extended . . . to 16,000 hoursor more. In addition, the improved dirt-free constructionof modern luminaires can mean once-a-year cleaning in-stead of twice-a-year.

Notrs Sglaania Dlerearu Lannps tlake Colors Look Tru,er-to-LifeNot only has Sylvania improved life and light output inmercury lamps, but it has also pioneered a striking colorinnovation Silver White that makes Sylvania MercuryLamps adaptable to more applications than ever.

Choiee of eolorsStandard Clear - where color is not a major consideration.Standard Clear mercury lamps produce a blue-white lightwith strong spectral lines in the violet blue' green andyellow regions of the spectrum. This intense light source isthe "work-horse" of the mercury line. The blue-white ofthe Clear mercury lamp is ideal for many applications inindustry and street lighting.Color Improved - where red rendition is important. ColorImproved mercury lamps enhance color rendition, especiallyin the red end of the spectrum with but a small sacrifice inlumens. The warmer more diffuse light of this phosphorcoated lamp is desirable for applications where the richerred rendition is preferred.Silver White - where broad color identification is a factor.Sylvania was fi.rst in the industry to develop the SilverWhite lamp that improves the color of mercury in all regionsof the spectrum with a/l colors visible - yet at no sacrificeof light output.Cornhine with tluorescent lightingTo improve color rendition, 60/6 to 80/6 of the totallight output should be provided by mercury lamps and theremainder by fluorescent tubes.In such combinations fixtureheight must be low enough for effective distribution oflight; for example, in bays up to 35 feet high. Fluorescentfixtures should be located for easy servicing and not ex-posed to excessive dirt.Cornhine with ineand,eseentlightingFor 40-foot bays or higher, incandescent must be com-bined with mercury. At least 75/6 of the total light outputshould be supplied by the mercury. This provides the ad-vantages of uniform fixtures for both types of lamp, mosteffective light control, simple maintenance and cleaning . . .least surface to collect dirt.

in Better Lighting ut Lowest eostm to mercury. The result is Jour times the light output atonly double the wattageFor example, Sylvania's Clear 400-watt, 20,500 lumenmercury lamp produces light at the lowest cost per 1000effective lumens. The chart below compares this to a

620-watt, 10,000 lumen incandescent and a fluorescent fix-ture made up of four 160-watt 6'VHO's (43,600) lumens:

Or compare Sylvania's 775-watt 7600with a 6,000 lumen incandescent andfluorescent :

Or look at mercury's comparative savings in terms ofcost per million lumen hours. With Sylvania's 400-wattmercury, the cost of light production can be $.80 per millionlumen hours, compared with $1.30 for the largest incandes-cent, 860 watt, 15,000 lumen lamp. With Sylvania's77S-watt mercury, it's $1.45 per million lumen hours, com-pared with $1.70 for a widely used incandescent rated at405 watts, (r,000 lumens.On top of all this, you save substantially on maintenancecosts. Mercury's three to five-year burning periodpared with an average incandescent life of 6 months -means you can eliminate at least five replacement servicetrips in the field.Yes, you'll find mercury lighting gives you more light atlower cost - makes more efficient use of power - than anyother source.These three case studies show how much MORE efficiencyand economy you can get with Sylvania mercury lamps thanwith incandescent.

*All Sylvania Mercury Lamps can be 0perated in any burning position. The ratingssiven in the table above are representalive of pholometry of lamps life tesled invertical and horizontal burning positions. The photomelry is ped0rmed with the lampoperated in a vertical burning position. When mercury lamps are operated in a hori-zintal position without wattage or lumen compensated ballasts, the ratings in thetable above should be decreased by 5%.

Sylvania Mercury Lamps are particularly designed forgroup replacement service., Bases are Mogul except PAR Lamps which haveAdmedium bases.

**Used in areas where present luminaires have restricted lamp space.x**Heat-resistant, weather-durable, hard glass outer jacket, is standard in all SylvaniaMercury Lamps.
