than .72 with a spacing to mounting ratio of 1.5 perpendicular to the lamps. To
meet IES RP1 preferred requirements for VDT areas the VCP (visual comfort proba-
bility) shall not be less than 90 either crosswise or lengthwise and the maximum
average brightness at 55°, 65°, 75° and 85° shall not exceed 745, 0, 0 and 0 can-
delas per square meter respectively in the 0°, 45°, and 90° horizontal planes.
