This invention provides a lighting fixture for use in low-ceiling applications and/or outdoor environments, such as parking garages that allows for the use of more- efficient lighting sources, such as fluorescent lamps, with more-even distribution of light along the sides of the fixture so that the surrounding space is fully and efficiently illuminated. Two elongated light sources are mounted upon opposing sides, and surrounded by a pair of respective side reflectors. The side reflectors direct the light of the two light sources in a generally sideward and somewhat-downward direction. The lower portion of the side reflectors collectively define an overall wide angle and each lower portion completely overlies a respective one of the side light sources mounted above. A third light source can be located centrally, beneath the lower portions to provide downward light, which is further reflected generally downwardly by the wide angled lower portions. Alternatively, each of the lower reflector portions can include a set of elongated slots near the center of the fixture, allowing light to pass into the lower area of the reflector in a generally downward direction. A central angled reflector can further divide and reflect the light passed through the two sets of slots. The reflectors and light sources are mounted on the internal box of a housing constructed from metal, polymer, composite, and the like. A transparent/translucent cover is removably sealed to the housing, using an intervening perimeter gasket.
