Specifications

Performance: In an installation of 2 lamps 40 W luminaires in a room cavity ratio of 1, with reflectance of 80% ceiling, 50% walls, 20% floor, the C.U. shall not be less than .89. To reduce glare the VCP shall not be less than 37 either lengthwise or crosswise (at 100 fc level) and the average brightness at 65 shall not exceed 3956 footlamberts. To control veil- ing reflections, luminaire output in the 30°-90° zone shall be not less than 68%.

Specifications (continued)
