Specifications
Performance: In an installation of 2 lamp 28W luminaires in a room cavity
ratio of 1, with reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not
be less than .78. To reduce glare the average brightness at 65° shall not exceed
1109 candelas per square meter. To control veiling reflections, luminaire output
in the 30°-90° zone shall not be less than 64.1%.
Air Handling: (SKA only) side air passages for air supply or air return. Supply
air is discharged vertically. Optional side closure strips. Air return is also provid-
ed through the lamp compartment through fixture body ends.
Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing has
side rails hemmed over and housing ends turned-in for safe handling.
Finish: Chassis exterior–black baked polyester enamel. Cavity–white baked
polyester enamel minimum 86% reflectance. Rust preventative undercoating.
Reflectors- 95% reflective white powder coated.
