Lamp Performance Data
D = Distance to the horizontal or vertical surface.
FC = Initial footcandles at the center of the beam.
L = Length of the beam where candlepower is reduced to 50%
of center beam candlepower.
W = Width of the beam where candlepower is reduced to 50%
of center beam candlepower.
CB = Distance to the center of the beam.
Lamp data given is typical and is based on bare lamp performance.
Contact lamp manufacturers for availability and specific performance.
Distance, length and width given in decimal feet.
