A conversion replacement apparatus for HID screw-in mercury vapor, metal halide or high or low pressure sodium lamps utilizes the reflector typically employed with such lamps. The HID lamp is removed from the reflector. A fluorescent lamp support frame then is attached to the base end of the inside of the reflector to extend to a point substantially one-fourth to one-half of the distance between the base end and the light-emitting end of the reflector. The support includes a plurality of extensions for holding the bases of compact fluorescent lamps arranged in a general star configuration around the center line of the reflector. The extensions are bent at an angle to cause the compact fluorescent lamps to follow the outwardly-flared inside surface of the reflector. Ballasts for the lamps are located in a housing attached to the base end of the reflector. Additional controls are provided for selectively supplying power to different ones of the ballasts for the fluorescent lamps to effectively provide "dimming" of the overall light output from the fixture.
