SPECIFICATIONS
PERFORMANCE: In an installation of 3 lamp 32W luminaires in a room cavity
ratio of 1, with a reflectance of 80% ceiling, 50% wall, 20% floor, the C.U.
shall not be less than .75. To prevent glare the VCP shall be not less than 85
either lengthwise or cross wise (at 100fc level) and the average brightness at
65° shall not exceed 610 footlamberts. To control veiling reflections, luminaire
output in the 30°-90° zone shall be not less than 69%.
