SPECIFICATIONS

PERFORMANCE: In an installation of 2 lamp 32W luminaires in a room cavity ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .63. To prevent glare the VCP shall not be less than 55 either length- wise or crosswise (at 100 fc level) and the average brightness at 65° shall not exceed 647 footlamberts. To control veiling reflections, luminaire output in the 30° - 90° zone shall be not less than 63.5%.

SPECIFICATIONS (continued)

MATERIALS: Chassis parts are die-formed 20 gauge cold rolled steel, stud- welded for rigidity. Lens Frame—(FA) flush full-size aluminum frame, (FS) flush full-size steel frame, (RA) regressed full-size aluminum frame, (RF) 1/2" regressed floating aluminum frame with 7/16" black reveal, four sides. FINISH: Chassis exterior—white baked acrylic enamel. Cavity—white baked acrylic enamel minimum reflectance 86%. 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./UL and C-UL.
