Abstract

A replacement light fixture (10) for directing light emitted from a light source (12) toward an area to be illuminated, including a base member (20) upon with the light source (12) is positioned and a reflector assembly (90) detachably secured to a first and second mounting brackets (50, 52) that are mounted to a portion of the preexisting light fixture housing such that a lens portion (110) of the reflector assembly (90) overlies the light source (12) and such that substantially all of the light emitted from the light source (12) passes through the lens portion (110).
