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 .59.
To prevent glare the VCP shall be not less than 71 either lengthwise or crosswise (at 100fc
level) and the average brightness at 65° shall not exceed 1338 candelas per square meter.
To control veiling reflections, luminaire output in the 30°-90° zone shall not be less than
62.7%.
AIR HANDLING
(MPA only) side air passages for air supply or air return. Supply air is
discharged vertically. Optional side closure strips. Air return is also provided through the
lamp compartment through fixture body ends.
MATERIALS
:
Chassis parts
are die-formed code gauge cold rolled steel. Housing is
ribbed for rigidity with side rails hemmed over and housing ends turned-in for safe handling.
Louver
is pre-anodized
aluminum (Coilzak
®
or equal).
FINISH
:
Chassis exterior
–black baked polyester enamel.
Cavity
– white baked poly-
ester enamel minimum 86% reflectance. Phosphate undercoating.
Louver
–low irides-
cence semi-specular anodized vertical grain aluminum reflector sheet is standard.
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.
