SPECIFICATIONS

PERFORMANCE: In an installation of 2 lamp 31W luminaires in a room cavity

ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be
less than .73. To prevent glare the VCP shall be not less than 40 either length­wise or crosswise (at 100fc level) and the average brightness at 65° shall not
exceed 2144 candelas per square meter. To control veiling reflections, luminaire
output in the 30°-90° zone shall not be less than 66.0%.

SPECIFICATIONS (continued)

MATERIALS: Chassis parts are die-formed code gauge cold rolled steel.

Housing with side rails hemmed over and housing ends turned-in for safe han­dling.
FINISH: Chassis exterior—black baked polyester enamel. Cavity—white
baked polyester enamel minimum 86% reflectance. Phosphate undercoating.
LENS: (VK) prismatic lens is 3/16" thick, pattern 12, minimum impact strength,
130 foot pounds.
ELECTRICAL: Thermally protected class "P” ballast C.B.M. approved, non PCB.
