SPECIFICATIONS

PERFORMANCE: In an installation of 2 lamp 32W luminaires in a room cavity ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .72. To prevent glare the VCP shall be not less than 86 either lengthwise or crosswise (at 100fc level) and the average brightness at 65° shall not exceed 1984 candelas per square meter. To control veiling reflections, luminaire output in the 30°-90° zone shall be not less than 67.4%.
