Specifications

Performance: In an installation of 2 lamp 28W semi-specular luminaires in a room cavity ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .56 with a spacing to mounting ratio of 1.3 perpendicular to the lamps. To meet IES RP-1 for VDT areas the VCP (visual comfort probability) shall not be less than 87 either crosswise or lengthwise and the candela value between 55° and 90° in the 0° to 90° planes shall not exceed 2858. Candelas at Nadir (0°) not to exceed 1373.

Air Handling-(LIA) side air passages for air return. Materials: Chassis parts are die-formed cold rolled steel. Louver: Pre-anodized aluminum (Coilzak® or equal).

Specifications (continued)

Finish: Louver—specular or semi-specular low iridescence pre-anodized

reflector sheet. Reflector: White baked polyester enamel or specular reflector. 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.
