An incandescent light bulb life extending apparatus operates by modifying or wave shaping the A.C. power that supplies power to a lamp or light fixture, using a phase control circuit that is fixed at a specific phase that does not change. The light bulb life extending apparatus is housed in a plug in/plug into enclosure with prongs on one side that plug into a standard ordinary A.C. wall socket or receptacle, and a lamp power cord or similar light fixture power cord then plugs into the receptacle located on the opposing side of the enclosure.
