SPECIFICATIONS

PERFORMANCE: In an installation of 2U lamp 31W luminaires in a room cavi- ty ratio of 1, with a reflectance of 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .64. To prevent glare the VCP shall be not less than 77 either lengthwise or cross wise (at 100fc level) and the average brightness at 65° shall not exceed 2319 footlamberts. To control veiling reflections, luminaire output in the 30°-90° zone shall be not less than 68.4%.

SPECIFICATIONS (continued)

MATERIALS: Chassis parts are die-formed 20 gauge cold rolled steel, stud- welded for rigidity with all seams finished smooth.

LOUVER: pre-anodized aluminum (Coilzak® or equal).

STANDARD FINISH: Louver—low iridescence, semi-specularpre-anodized vertical grain reflector sheet. Cavity—white baked acrylic enamel minimum 86% reflectance. Phosphate undercoating. Chassis exterior—white baked acrylic enamel.

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°.
