WRAP-AROUND PARABOLIC LIGHT FIXTURE AND METHOD FOR MANUFACTURE ABSTRACT OF THE DISCLOSURE An improved light fixture for housing an elongated lamp and method for making same, the fixture having an elongated housing constructed from a continuous rectangular piece of sheet metal having four parallel bends therein forming planar side walls. The planar side walls form flange planes suitable for mating within grooves formed in suitable end pieces for the housing. The closure lens completes the housing. The construction of the elongated housing side walls is such that a reflector sheet when curvedly affixed to the two outermost planar side walls is tangential to the inner three planar side walls, thereby providing a parabolic reflecting surface for a lamp mounted within the reflector sheet. Two end wall reflectors, preferably one of which is directionally adjustable, also reflect luminous flux from the lamp. An adjustable light support for the non-electrical end of the elongated lamp, along with the adjustable end wall reflector, conveniently allows the improved light fixture to accept various sized elongated lamps without substantial loss of light reflecting capabilities.
