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 .81. To reduce glare the VCP shall not be less than 43 either lengthwise or crosswise (at 100 fc level) and the average brightness at 65° shall not exceed 1411 footlamberts. To control veiling reflections, luminaire output in the 30°-90° zone shall be not less than 68.6%.

MATERIALS: Chassis parts are die-formed code gauge cold rolled steel. Housing is reinforced for rigidity. Refractor—one-piece virgin acrylic.

FINISH: Chassis exterior—white baked polyester enamel. Cavity— white baked polyester enamel minimum 86% reflectance. Phosphate undercoating.

LENS: One-piece injection molded full re-entrant virgin acrylic with Catadioptric sides, ends and wall design with diamond sharp square base male conical prisms on horizontal surface.

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.

We reserve the right to change design, materials and finish in any way that will not alter installed appearance or reduce function and performance.
