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 .76 with a spacing to mounting ratio of 1.8 perpendicular to the lamps. To meet IES RP1 preferred requirements for VDT areas the VCP (visual comfort proba- bility) shall not be less than 93 either crosswise or lengthwise and the maximum average brightness at 55°, 65°, 75° and 85° shall not exceed 834, 0, 0 and 0 can- delas per square meter respectively in the 0°, 45°, and 90° horizontal planes. Candelas at Nadir (0°) not to exceed 1437.

SPECIFICATIONS (continued)

AIR HANDLING: (VPA only) side air passages for air supply or air return. Optional side closure strips. Air return is also provided through the lamp com- partment through fixture body ends.

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

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

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

LABELS: I.B.E.W./UL and C-UL.
