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 compartment 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).
