Specifications

Performance: In an installation of 2 lamp 28W luminaires in a room cavity

ratio of 1, with reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not
be less than .78. To reduce glare the average brightness at 65° shall not exceed
1109 candelas per square meter. To control veiling reflections, luminaire output
in the 30°-90° zone shall not be less than 64.1%.
Air Handling: (SKA 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.
