ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less
than .57 with a spacing to mounting ratio of 1.8 perpendicular to the lamps. To
meet IES RP1 preferred requirements for VDT areas the VCP (visual comfort proba-
bility) shall not be less than 92 either crosswise or lengthwise and the maximum
average brightness at 65°, 75° and 85° shall not exceed 267, 121 and 72 candelas
per square meter respectively in the 0°, 45°, and 90° horizontal planes. Candelas
at Nadir (0°) not to exceed 1224.
