Specifications

Performance: In an installation of 2 lamp 32W luminaries in a room cavity ratio of 1,

reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .89. To prevent
glare the VCP shall be not less than 72 either lengthwise or crosswise and the average
brightness at 65° shall not exceed 2157 candelas per square meter. To control veiling reflec­tions, luminaire output in the 30°-90° zone shall not be less than 71.9%.

Materials: Power Tray parts are die-formed code gauge cold rolled steel.
Finish: Power Tray–95% reflective white baked polyester enamel. Rust preventative
undercoating. Louver–95% reflective flat white powder coat.
