Claim:
A lighting fixture consisting of: a) a lamp fixture housing; b) a pair of lamp socket and mount assemblies each containing a plurality of lamp sockets having one lamp socket and mount assembly affixed to each end of said lamp fixture housing wherein one lamp socket from each of the pair of lamp socket and mount assemblies provides connection to each end of a fluorescent lamp; c) a static reflector mounting strut rigidly and non moveably affixed to said lamp fixture housing; d) a moveable reflector support assembly for mounting a reflector; e) said reflector having at least one reflector cavity suitable for housing fluorescent lamps, wherein said reflector cavity is chosen from a group consisting of a single near parabolic like shape, a pair of intersecting near parabolic like shapes, or three intersecting near parabolic like shapes for creating an illumination light field with excellent lighting coverage and high efficiency light output, wherein each parabolic like shape houses a fluorescent lamp; f) said intersecting near parabolic like shapes beneficially create a narrow lamp fixture housing; g) said reflector mounted to said moveable support assembly is adjustably mounted to said reflector mounting strut wherein the moveable reflector support assembly is moved toward the fluorescent lamps to create a narrow illumination light field and away from the fluorescent lamps to create a wide illumination light field; h) said illumination light field being adjusted by operating an illumination light field adjusting means; i) at least one electronic ballast suitable for providing power for starting and operating at least one fluorescent lamp wherein said electronic ballast are housed in a ballast cavity within said lamp fixture housing to provide service and installation access to said electronic ballasts and a wiring thereof; and j) a means for hanging said lighting fixture.
