Specifications
Performance
: In an installation of 2 lamp 31W luminaires in a room cavity ratio of 1, reflectance
80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .71. To prevent glare the VCP shall
be not less than 63 either lengthwise or crosswise (at 100fc level) and the average brightness at 65°
shall not exceed 2502 candelas per square meter. To control veiling reflections, luminaire output in
the 30°-90° zone shall not be less than 67.2%.
