SPECIFICATIONS

PERFORMANCE: In an installation of 1 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 .79 with a spacing to mounting ratio of 1.6 perpendicular to the lamps. To meet IES RP-1 preferred for VDT areas the VCP (visual comfort probability) shall not be less than 94 either crosswise or lengthwise, and the maximum average

brightness at 55°, 65°, 75° and 85° shall not exceed 664,109, 0, and 0 candelas per square meter respectively in the 0°, 45° and 90° horizontal planes. Candelas at nadir (0°) not to exceed 967.

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 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—specular low iridescence pre-anodized reflector sheet.

REFLECTOR: Low-iridescence,semi-specular with low iridescence specular center section. 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.
