SPECIFICATIONS:

PERFORMANCE: In an installation of 4 lamp 32W 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 .80. To reduce glare the average bright­ness at 65° shall not exceed 3388 footlamberts. To control veiling
reflections, luminaire output in the 30°-90° zone shall be not less than

66.4%.
MATERIALS: Chassis parts are die-formed code gauge cold rolled
steel. Housing is reinforced for rigidity. Refractor–one-piece virgin
acrylic..

FINISH: Chassis exterior–white baked polyester enamel. Cavity–white
baked polyester enamel minimum reflectance 86%. Phosphate under­coating.
LENS: One-piece extruded prismatic pattern 12 bottom and linear prism
side walls.
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.
