A lighting fixture has a reflector and a socket mounted within a frame. The socket is mounted within the frame to be positionable with respect to the reflector for accommodating various sizes of lightbulbs. Specifically, the light source or filament within the lightbulb is always positioned at the same location with respect to the reflector, irrespective of the size of the lightbulb, by moving the socket within the frame. |
