Specifications

Performance: In an installation of 2 lamp 32W luminaires in a room cavity ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .85. To prevent glare the VCP shall be not less than 75 either lengthwise or crosswise (at 100fc level) and the average brightness at 65° shall not exceed 1606 candelas per square meter. To control veiling reflections, luminaire output in the 30°-90° zone shall not be less than 72.0%.

Air Handling (DPA only) side air pasaages for air supply or air return. Supply air is discharged vertically. Optional side closure strips. Air return is also provided through the lamp compartment through fixture body ends.

Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing is ribbed for rigidity with side rails hemmed over and housing ends turned-in for safe handling. Louver is pre-anodized aluminum (Coilzak® or equal.

Specifications (continued)

Finish: Chassis exterior–black baked polyester enamel. Cavity–white baked polyester enamel minimum 86% reflectance. Phosphate undercoating. Louver–low iridescence semi- specular anodized vertical grain aliminum reflector sheet is standard.

Electrical: Thermally protected class “P” ballast C.B.M. approved, non PCB. If K.O. is with- in 3" of ballast, use wire suitable for at least 90°.

Labels: I.B.E.W. UL and ULc Listed.
