Abstract
The present invention is directed to an improved recessed lighting fixture for flush mounting in a hung ceiling structure or the like. The fixture is characterized by its ability to be securely anchored in position, yet be readily removed from a position below the ceiling for the changing of bulbs, replacement of electrical connections, etc. The apparatus includes a frame permanently mounted above the ceiling, installation of the reflector and attached light source components being effected by simple vertical movement of the reflector assembly. Removal of the reflector assembly from the frame is accomplished by a relative rotation of the reflector and frame.
