parallel to the ground. In order to achieve a total cutoff at 90 degrees, the luminaire \Vill emit
maximum (peak) candle power at an angle not exceeding 75 degrees. This angel is funned by
the line at which maximum candlepov,rer is emitted for the light source and a line perpendicular
to the ground from the light source.

center point of the light fo(ture, but shall not exceed those maximums beyond the exterior
