SPECIFICATIONS

PERFORMANCE: Luminaire distribution is to be a minimum of 97.5% in the 0°- 60° zone. 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 .80 with a spacing to mounting ratio of 1.6 perpendicular to the lamps. To meet IES RP1 recommended (basic) requirements for VDT areas the VCP (visual comfort probabili- ty) shall not be less than 90 either crosswise or lengthwise, and the maximum

SPECIFICATIONS (continued)

average brightness at 65°, 75° and 85° shall not exceed 617, 191 and 162 can- delas per square meter respectively in the 0°, 45° and 90° horizontal planes. AIR HANDLING: (STA 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 is embossed for rigidity with all edges turned-in for safe handling. LOUVER: Pre-anodized aluminum (Coilzak® or equal).

FINISH: Louver—semi-specular low iridescence pre-anodized reflector sheet. Reflector—95% reflective specular. Phosphate undercoating.

Chassis exterior—black baked polyester enamel.

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.
