The conductor blades extend downwardly from the bulb receptacle so as to define a male conductor plug within the handle portion. The female end of a extension cord set is received into the handle portion through the hinged door, and matingly engaged with the conductor blades so as to establish an electrical connection between the bulb receptacle and the cord set.
