SPECIFICATIONS
PERFORMANCE: In an installation of 2U lamp 31W luminaires in a room cavi-
ty ratio of 1, with a reflectance of 80% ceiling, 50% wall, 20% floor, the C.U.
shall not be less than .64. To prevent glare the VCP shall be not less than 77
either lengthwise or cross wise (at 100fc level) and the average brightness at
65° shall not exceed 2319 footlamberts. To control veiling reflections, luminaire
output in the 30°-90° zone shall be not less than 68.4%.
SPECIFICATIONS (continued)
