ABSTRACT:
A water submersible light fixture for water fountains and the like comprises a light housing with concave light reflective surface, a light bulb positioned in the space defined by the concave light reflective surface and light bulb socket secured to a support which is sealingly engaged with the housing. The housing is submersed to cool and maintain the concave light reflective surface as exposed to the high temperatures produced by the light bulb. The positioning of the light bulb is predetermined by its length to locate the bulb relative to the reflective surface to provide the desired degree of light focus.
