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.
