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 .72 with a spacing to mounting ratio of 1.5 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 745, 0, 0 and 0 can-
delas per square meter respectively in the 0°, 45°, and 90° horizontal planes.

AIR HANDLING:

(VPA 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

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 specular anodized vertical grain aluminum reflector

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 C-UL.
