Specifications
Performance: In an installation of 2 lamp 31W 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 73. To prevent glare the VCP shall not be less than 83 either
lengthwise or crosswise (at 10Ofc level) and the average brightness at 65° shall
not exceed 2817 candelas per square meter. To control veiling reflections,
Iuminaire output in the 30°-90° zone shall not be less than 68.9%.
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.
