ABSTRACT:
A luminaire for use with HID lightbulbs includes a housing having four primary identical compound curve reflector sections oriented with two sections on each side of the lamp to cause major projections of the light emanating from the luminaire diagonally of the longitudinal axis of the lamp in a horizontal plane to create a square or rectangular distribution of light on the surface to be illuminated. Auxiliary reflector sections are placed at the ends of the light bulb and interconnect the main reflector sections to create an increase in the light projected along the lamp axis to compensate for the reduction in inherent lamp intensity along its axis.
