ABSTRACT:
A light fixture is described. The light fixture includes a socket housing and a reflector housing. The socket housing includes a socket for receipt of a lamp, and a reflector housing mounting surface. The reflector housing includes a direct reflector for providing direct light onto a target lighting area and an indirect reflector for providing indirect light onto the target lighting area. The direct reflector includes a direct reflector first end, a direct reflector second end, and a direct reflector body extended between the first end and the second end. The direct reflector body extends sufficiently far to provide a cut off angle between a lamp provided in the socket and the direct reflector second end of less than about 50°. The indirect reflector extends from the direct reflector around a circumference of the direct reflector in an amount sufficient to shield a lamp provided in the socket. A facility having a plurality of ceiling mounted light fixtures, and a reflector housing are described.
