Crisp,compact lensesprovide uniform lightdistribution, using
fewerwatts and fewerfixtures.
Trim Prismawrap lenses distribute abroader light pattern than
conventionalwraparound lenses, and achieve uniformfootcandle levels
with the 1,2,3 or 4 lampunits spaced farther apart.This means lower
initial costs andreduced energy consumption forcontinued
savings.Optics minimize glare.Specially engineered sidewall
opticsdeliver an upward component thatreduces ceiling contrast, and
adownward component below the glarezone that directs more useful
light intothe work area.This is achieved by precise
Holophaneprismatic design and advancedinjection -molding
techniques. Thus,glare is minimized.The uplight prismatic component
and thebollom Lransverse ano rongitudinal pr,srdesign of the 6100-A
make it idealforcontinuous-row application in corridorsand aisles
up to 10' wide. Uniqueprismatic array of the 7100-A and7400-A
provides a widespread lightdistribution, obscures lamp images
andmasks dark lamp ends for clean, crispluminaire
appearance.Performance.tested.Prismawrap lenses are manuf
acturedfrom tough, crystal clear acrylic.Performance -tested in
thousands ofapplicatlons, Prismawrap is the logicalchoice for
highly efficient wraparoundfluorescent lenses.lmpact-reslstant
option.The standard acrylic Prismawrap lensesare exceptionally
srrorg. But for pLblrcareas such as schools and halwayswhere
vandalism can create severebreakage problems, 7100-DR-A and7400-DF
-A high-impact resistant lensesare also available.These Plexiglas
DR. lenses, molded ofhigh-impact resistant acrylic, offer thesame
light distribution as the standardPrismawrap lenses, yet have 3 to
5 timesthe impact strength ol standard ones.Thus, costly
replacement of vandalizedlenses and lamps can be
greatlyreduced.'Plexiglas and DR are registered lrademarks of
Cutaway seclion of Holophane Prismawrap 7100-A ens,showing
