ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less
than .67 with a spacing to mounting ratio of 1.9 perpendicular to the lamps. To
meet IES RP-1 recommended (basic) requirements for VDT areas the VCP (visual
comfort probability) shall not be less than 91 either crosswise or lengthwise and
the maximum average brightness at 65°, 75° and 85° shall not exceed 837, 82 and
41 candelas per square meter respectively in the 0°, 45° and 90° horizontal planes.
Candelas at Nadir (0°) not to exceed 652.
