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%.
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.

Specifications (continued)

Finish: Chassis exterior–black baked polyester enamel. Cavity–white baked polyester enamel minimum 86%

reflectance. Rust preventative undercoating. Louver–low iridescence semi-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 ULc Listed.
This product may have a mercury containing lamp.
Manage in accord with Disposal Laws.
