Specifications
PERFORMANCE: In an installation of 3 lamp 40W luminaires in a room cavity
ratio of 1, with reflectance of 80% ceiling, 50% wall, 20% floor, the C.U. shall
not be less than .78. To reduce glare the VCP shall be not less than 48 either
lengthwise or crosswise (at 100fc level) and the average brightness at 65° shall
not exceed 760 footlamberts To prevent veiling reflections, luminaire output in
the 30°-90° zone shall not be less than 64.7%.
MATERIALS: Chassis parts are die-formed code gauge cold rolled steel.
FINISH: Chassis exterior–white baked polyester enamel. Cavity– white baked
polyester enamel minimum 86% reflectance. Phosphate undercoating.
Specifications (continued)
LENS: One-piece extruded virgin acrylic prismatic bottom and side walls.
END CAPS: Injection molded catadioptic end caps separate from 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.
