Specifications
Performance:
In an installation of 1 lamp 54W luminaires in a room cavity of 1,
with reflectance of 80% ceiling, 50% walls, 20% floor, the C.U. shall not be less
than .82. To reduce glare the average brightness at 65° shall not exceed 2146
candelas per square meter. To control veiling reflections, luminaire output in the
30°-90° zone shall not be less than 74.9%.

is die-formed 20 gauge steel.
Finish: Chassis exterior
–baked white acrylic enamel.
Reflector
–baked flat
white acrylic enamel, minimum 86% reflectance. Phosphate undercoating.
