SPECIFICATIONS

PERFORMANCE: In an installation of 3 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 .70 with a spacing to mounting ratio of 1.4 perpendicular to the lamps. To meet IES RP1 recommended (basic) requirements for VDT areas the VCP (visual comfort probability) shall not be less than 94 either crosswise or lengthwise and the maximum average brightness at 65°, 75° and 85° shall not exceed 304, 147, and 0 candelas per square meter respectively in the 0°, 45°, and 90° horizontal planes.

SPECIFICATIONS (continued)

AIR HANDLING: (VRA 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 embossed cold rolled steel. Housing side rails hemmed over and housing ends turned-in for safe handling. LOUVER: 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 semi-specular anodized vertical grain aluminum reflec- tor 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.
