Specifications
Performance: In an installation of 2 lamp 32W Iuminaires in a room cavity ratio
of 1, with reflectance of 80% ceiling, 50% wall, 20% floor, the C.U shall not be
less than 84. To prevent glare the VCP shall not be less than 86 either lengthwise
or crosswise (at 100fc level) and the average brightness at 65° shall not exceed
1347 foot-Iamberts. To control veiling reflections, luminaire output in the 3C°-90°
zone shall not be less than 72.1%.
Specifications (continued)
Air Return: Designed to provide optimum air return. Air is returned through the
lamp compartment for all ceiling systems and direct to plenum through slots in
slot grid and narrow grid ceiling systems.
Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing
is embossed for rigidity with all edges turned up for safe handling. Louver is
pre-anodized aluminum (Coilzak
®
or equal).
Finish: Louver–semi-specular anodized low iridescence, vertical grain reflector
sheet. Cavity–white baked polyester minimum 86% reflectance. Phosphate
undercoating. Chassis exterior–black baked polyester enamel.
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.
