SPECIFICATIONS

PERFORMANCE: In an installation of 2 lamp 17W luminaires in a room cavity ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .68 with a spacing to mounting ratio of 1.4 perpendicular to the lamps. To meet IES RP1 preferred requirements for VDT areas the VCP (visual comfort proba- bility) shall not be less than 90 either crosswise or lengthwise and the maximum average brightness at 55°, 65°, 75° and 85° shall not exceed 637, 32, 13 and 0 candelas per square meter respectively in the 0°, 45°, and 90° horizontal planes.

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).
