Specifications

Performance: In an installation of 2 lamp 24W luminaires in a room cavity of 1, with reflectance of 80% ceiling, 50% walls, 20% floor, the C.U. shall not be less than .88. To reduce glare the average brightness at 65° shall not exceed 3629 candelas per square meter. To control veiling reflections, luminaire output in the 30°-90° zone shall not be less than 74.8%.

Materials: Housing is die-formed 20 gauge steel.

Finish: Chassis exterior–baked white acrylic enamel. Reflector–baked flat white acrylic enamel, minimum 86% reflectance. Phosphate undercoating. Lamp Shield–white virgin acrylic lens.

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.
