ABSTRACT:
A lighting fixture for lighting a large area such as a sporting field. The lighting fixture has a bowl-shaped reflector with an internal glare and spill control assembly for aiming and controlling the light emitted therefrom. The glare and spill control assembly is located within the bowl-shaped reflector and behind the lens cover of the lighting fixture so that the glare and spill control assembly is substantially isolated from the effects of weather. The glare and spill control assembly preferably has a plurality of arc-shaped louvers located substantially in the upper half of the reflector for controlling glare and spill of the light from the lamp. The lower half of the reflector preferably has either a reflector insert for redirecting light more parallel to the central aiming axis, or a light absorbing baffle for reducing glare.
