Bantam Prismatiteuses a prismatic refractor,instead of a conventionalglobe, for more lightand better light control.

Optics engineers know that refractor design determines how efficienta luminaire will be.Conventional vertical-ribbed or clear globes simply transmit Iight raysvirtually unimpeded, with about 40Va of lhe light emitted upward. Formost outdoor applications, such upward light is wasted.PRISMATITE, on the other hand, bends the light into desired areas. Thiseffect is achieved by a combination of the complex optical train of pre-cisely-formed prisms and the carefully designed contour of the glassrefractor itself. (Fig. 1)

CHOICE OF LIGHT DISTRIBUTIONS.Asymmetrical refractor series isideal for lighting long, narrowareas, such as walkways, loadingplatformg and parking structures.It allows spacing up to 2t/2 limesas far apart as other units. Forinstance, PRTSMATITE spaced on25' centers will provide the sameuniformity of light as conven-tional units spacerl on 10' centers-while prcducing higher lightlevels. It is also unnecessary totilt the luminaire to achieve theproper illumination on a catwalk,for instance, when using a stan-chion mount.S'.mmetrical refractor series isideal for lighting general areassuch as open storage and outdoorstairs. Because the refractor di-rects more light downward andoutward, the number of lumi-naires required to achieve a givenlight level is reduced by as muchas one third,With either refractor, thismeans lower luminaire cost, lowerinstallation cost, lower mainte-nance cost and less power con-sumption,BETTER 'SEE.ABILITY".Since glare reduces the ability tosee, a decrease in glare becomesparticularly important in hazard-ous areas where safety is critical.The PRISMATITE refractor re-duces brightness - the chief causeof glare - by spreading the lampimage over a total surface arealhat is 50ak greater than that ofa conventional globe, while pro-viding increased useful light,OVERCOMES MINIMAL HEADROOMPROBLEMS.Depth of the small PRISMATITEis only 12 inches (12% incheswith wireguard) to solve lowheadroom problems-REFRACTOR IS SHOCK"RESISTANT.The refractor is made of ENDU-RAL@ borosilicate glass, tailoredto the most demanding require-ments for thermal shock resist-ance and mechanical strength,Reduced likelihooal of refractorbreakage through vandalism oraccident also means less lampbreakage.
