Specifications
Performance: In an installation of 2 lamp 31W luminaires in a room cavity ratio of 1, reflectance
80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .76. To prevent glare the VCP shall
be not less than 41 either lengthwise or crosswise (at 100fc level) and the average brightness at 65°
shall not exceed 2572 candelas per square meter. To control veiling reflections, luminaire output in
the 30°-90° zone shall not be less than 66.9%.
Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing with side rails hemmed
over and housing ends turned-in for safe handling.
Specifications (continued)
Finish: Chassis exterior–black baked polyester enamel. Cavity–white baked polyester enamel
minimum 86% reflectance. Rust preventative undercoating.
Lenses: VA (standard) extruded virgin acrylic, 3/16" square based female cones, running 45° to the
panel edge, .095" nominal thickness (similar to pattern 12). VY (optional) .125" nominal pattern 12
with 7.8 oz. average weight per square foot. VI (optional) .125" nominal pattern 12 with 6.8 oz. aver-
age weight per square foot.
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.
