Specifications

Performance: In an installation of 2 lamp 14W luminaires in a room cavity ratio of 1, with reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .77. To reduce glare the average brightness at 65° shall not exceed 1202 candelas per square meter. To control veiling reflections, luminaire output in the 30°-90° zone shall not be less than 67.4%.

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.

Specifications (continuned)

Lens: Proprietary high quailty frost white acrylic and clear conical prism lens assembly.

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°.

UL Listed for damp locations. Labels: I.B.E.W./UL and ULc Listed.
