Specifications

Performance: In an installation of 2 lamp 40W luminaires in a room cavity ratio of 1, with reflectance 80% ceiling, 50% walls, 20% floor, the C.U. shall not be less than .61. To reduce glare the average brightness at 65° shall not exceed 2161 candelas per square meter. To control veiling reflections, luminaire output in the 30°-90° zone shall not be less than 75.2%.

Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing side rails hemmed over and housing ends are turned-in for safe handling.

Lamp Shields: 22 gauge steel perforated mesh lamp shield with white acrylic overlay.

Finish: Chassis exterior–black baked polyester enamel. Cavity–white baked polyester enamel minimum 86% reflectance. Phosphate undercoating.

Lamp Shield: Baked flat white acrylic enamel.
