Abstract
An underwater lighting fixture adapted for installation in a lamp receiving recess in the wall of a swimming pool. The fixture includes a lamp housing having a pair of reflector-mounted incandescent lamps mounted therein. A plate having a pair of apertures is mounted in the housing with the apertures mounted in alignment with the lamps. A pair of secondary reflectors are mounted to face the plate apertures and are provided with light-transmitting portals. A color wheel having dichroic filter segments is mounted so that identically colored pairs of segments pass the portals when the color wheel is driven by a motor. A synchronization circuit is responsive to an alternating-current source of power applied to the lighting fixture.
