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.
