Quick Calculators & Ceiling Brightness

Readings are rounded off based on initial footcandles at center of 20-foot run of luminaries. Room reflectance are 80% ceiling, 50% wall and 20% floor.

Data is based on bare lamp photometrics. Dashed lines in beam spreads indicate narrow axes of oval shaped beams.

FC is initial footcandles at center of beam.

L and W are to the point that the candlepower drops 50% of maximum.
