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 length- wise 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 han- dling.

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. If K.O. is within 3" of ballast, use wire suitable for at least 90°.

LABELS: I.B.E.W./UL and C-UL.
