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 probability) 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 candelas 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 compartment 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).
