Specifications
Performance: 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 .85. To prevent
glare the VCP shall be not less than 75 either lengthwise or crosswise (at 100fc level) and
the average brightness at 65° shall not exceed 1606 candelas per square meter. To control
veiling reflections, luminaire output in the 30°-90° zone shall not be less than 72.0%.
Air Handling (DPA only) side air pasaages for air supply or air return. Supply air is discharged
vertically. Optional side closure strips. Air return is also provided through the lamp compartment
through fixture body ends.
Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing is ribbed for
rigidity with side rails hemmed over and housing ends turned-in for safe handling. Louver is
pre-anodized aluminum (Coilzak
