A light bulb is provided that may be hung from a ceiling and which does need any type of light fixture thereabout. The light bulb itself acts as a fixture and is connected to a light socket having a top cover plate and a mounting piece mounting the top cover plate thereabove. In one embodiment of the invention, the mounting piece has a pair of diametrically opposed circumferential slots for receiving therein the prongs of the light bulb, the slots lying adjacent to a pair of metal terminals cast into the plastic of the mounting piece. A spring holding element holds the prongs in the slots. In the second embodiment, the mounting piece is threaded to receive a threaded portion of the light bulb and has a lower annular groove and central aperture for receiving therein a ring-shaped metal contact and a split prong contact of the light bulb. A plurality of metal strips partially positioned in the annular groove serve to hold the ring-shaped metal contact in place.
