glare the VCP shall be not less than 41 either lengthwise or crosswise (at 100fc level) and
the average brightness at 65° shall not exceed 2572 candelas per square meter. To control
veiling reflections, luminaire output in the 30°-90° zone shall not be less than 66.9%.
Air Handling: (PRA only) side air passages for air supply or air return. Supply air is dis-
charged vertically. Optional side closure strips. Air return is also provided through the lamp
