SPECIFICATIONS
PERFORMANCE:
Luminaire distribution is to be a minimum of 97.5% in the 0°-
60° zone. In an installation of 2 lamp 32W luminaires in a room cavity ratio of 1,
reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .80
with a spacing to mounting ratio of 1.6 perpendicular to the lamps. To meet IES RP1
recommended (basic) requirements for VDT areas the VCP (visual comfort probabili-
ty) shall not be less than 90 either crosswise or lengthwise, and the maximum
SPECIFICATIONS (continued)
average brightness at 65°, 75° and 85° shall not exceed 617, 191 and 162 can-
delas per square meter respectively in the 0°, 45° and 90° horizontal planes.
AIR HANDLING:
(STA only) side air passages for air supply or air return.
Optional side closure strips. Air return is also provided through the lamp com-
partment through fixture body ends.
MATERIALS: Chassis parts
are die-formed embossed cold rolled steel.
Housing
is embossed for rigidity with all edges turned-in for safe handling.
LOUVER:
Pre-anodized aluminum (Coilzak® or equal).
FINISH: Louver
—semi-specular low iridescence pre-anodized reflector sheet.
Reflector
—95% reflective specular. 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 C-UL.
