lamp performance:
D = distance to the horizontal or vertical surface.
FC = initial footcandles at the center of the beam.
L = length of the beam where the candlepower is reduced to 50% of center beam candlepower.
W = width of the beam where the 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 the lamp manufacturers for availability and specific performance. Distance, length and width are given in decimal feet.
