SPECIFICATIONS
PERFORMANCE: In an installation of 4 lamp 40 W luminaires in a room cavity
ratio of 1, with reflectance of 80% ceiling, 50% walls, 20% floor, the C.U. shall
not be less than .78. To reduce glare the VCP shall be not less than 42 either
lengthwise or crosswise (at 100 fc level) and the average brightness at 65 shall
not exceed 718 footlamberts. To control veiling reflections, luminaire output in
the 30°-90° zone shall be not less than 66%.
MATERIALS: Chassis parts are die-formed code gauge cold rolled steel.
Housing is embossed for added strength and rigidity with all edges rolled over
ratio of 1, with reflectance of 80% ceiling, 50% walls, 20% floor, the C.U. shall
not be less than .78. To reduce glare the VCP shall be not less than 42 either
lengthwise or crosswise (at 100 fc level) and the average brightness at 65 shall
not exceed 718 footlamberts. To control veiling reflections, luminaire output in
the 30°-90° zone shall be not less than 66%.
MATERIALS: Chassis parts are die-formed code gauge cold rolled steel.
Housing is embossed for added strength and rigidity with all edges rolled over
for safe handling. Lens frames—(XT) flat full-size steel frame, (XR) regressed
full-size aluminum frame.
FINISH: Chassis exterior—white baked polyester enamel. Cavity—white
baked polyester enamel minimum 86% reflectance. Phosphate undercoating.
LENS: Extruded virgin acrylic 3/16" square based female cones, running 45° to
the panel edge, .095" nominal thickness (similar to pattern 12).
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. Listed by Underwriters Laboratories.
