Specifications

Performance: In an installation of 3 lamp, 31W 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 78. To prevent glare the VCP shall not be less than 79 either lengthwise or crosswise (at 100fc level) and the average brightness at 65° shall not exceed 1078 footlamberts. To control veiling reflections, luminaire output in the 30° - 90° zone shall not be less than 67.3%.

Air Return: Designed to provide optimum air return. Air is returned through the

Specifications (continued)

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). rails hemmed over and housing ends turned-in for safe handling.

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.
