SPECIFICATIONS
PERFORMANCE: In an installation of 3 lamp 32W luminaires in a room cavity
ratio of 1, reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less
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 probability) 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 candelas per square meter respectively in the 0°, 45°, and 90° horizontal planes.
AIR HANDLING: (VPA only) side air passages for air supply or air return. Supply
air is discharged vertically. Optional side closure strips. Air return is also provided
through the lamp compartment through fixture body ends.
