Abstract
The present invention provides a luminaire fixture having a generally cup shaped upper housing casting. A bowl shaped reflector is mounted thereto. The lower rim of the upper housing includes a flange extending outwardly and downwardly therefrom. The upper surface of the reflector includes a plurality of vent openings near its upper edge. The reflector is fitted to the lower edge of the housing such that the upper housing flange covers the vent openings in the reflector to prohibit rain and snow from entering the reflector. Further, the upper housing includes a rim extension contacting the upper surface of the reflector to seal the upper housing ballast compartment for safety requirements.
