Abstract: A projection lighting unit which includes a U-shaped bracket member having an apertured faceplate and a rear upstanding wall, a glass reflector secured to the bracket's faceplate portion and including a concave reflecting portion and a rear neck portion adjacent thereto and including a cylindrical opening therein, a capsule member removably positioned within the reflector's rear opening and including an incandescent projection lamp (e.g., tungsten-halogen) and a cylindrical, metallic base member secured to the sealed end of the lamp, and a biasing flange member including a pair of cam springs which slidably engage the upstanding rear wall of the bracket during rotational insertion of the lamp capsule within the unit's reflector. The unit thus provides for rear removal of the lamp capsule from the glass reflector and bracket components.
