SPECIFICATIONS
PERFORMANCE: In an installation of 4 lamp 32W luminaires in a room cavity
ratio of 1, with reflectance of 80% ceiling, 50% wall, 20% floor, the C.U. shall
not be less than .67. To prevent glare the VCP shall be not less than 80 either
lengthwise or crosswise (at 100fc level) and the average brightness at 65° shall
not exceed 1098 candelas per square meter. To control veiling reflections,
luminaire output in the 30°-90° zone shall not be less than 64.8%.
AIR HANDLING (MPA only) side air passages 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.

SPECIFICATIONS (continued)
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® or
equal).
FINISH: Chassis exterior–black baked polyester enamel. Cavity– white
baked polyester enamel minimum 86% reflectance. Phosphate undercoating.
Louver–low iridescence semi-specular anodized vertical grain aluminum reflec-
tor sheet is standard.
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 ULc Listed.
