Specifications

Performance: 

In an installation of 3 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 82. To prevent glare the VCP shall not be less than 74 either lengthwise
or crosswise (at 100fc level) and the average brightness at 65° shall not exceed
1645 candelas per square meter. To control veiling reflections, luminaire output in
the 3C°-90° zone shall not be less than 69.7%.

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.
