ORDERING INFORMATION
Explanation of Catalog Number. Example: CBS232120SO
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 .81. To reduce glare the VCP shall not be less
than 43 either lengthwise or crosswise (at 100 fc level) and the average
brightness at 65° shall not exceed 1411 footlamberts. To control veiling
reflections, luminaire output in the 30°-90° zone shall be not less than
68.6%.
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 86% reflectance. Phosphate
undercoating.
LENS
: One-piece injection molded full re-entrant virgin acrylic with
Catadioptric sides, ends and wall design with diamond sharp square
base male conical prisms on horizontal surface.
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.
We reserve the right to change design, materials and finish in any way that will not alter installed appearance or reduce function and performance.
