ABSTRACT:
An adjustable lighting system which is particularly applicable for efficiently and effectively lighting areas of limited ceiling height such as parking garages and the like. A lamp base is supported within a housing in a manner so that it may be vertically adjustable with respect to a lower reflector carried by the housing. An upper reflector, which is vertically adjustable with respect to both the lamp base and the housing, is selected to provide a desired pattern of lighting for a particular installation. Although the lighting system may be employed with a plurality of different lamps, use of an induction lamp is preferred, and when an induction lamp is used, the combination of it with a novel, upper reflector of combined curvature having a central frustoconical downward section, is particular advantageous and provides excellent uniform distribution of illumination.
