Abstract
An incandescent electric light bulb is provided with two fittings, typically two opposed screw-threaded bases, each with two terminals. The bulb is provided with internal parallel conductors between corresponding terminals of the two fittings. One or more incandescent filaments is or are connected between the conductors within the bulb. Accordingly several of the bulbs may be connected fitting-to-fitting, electrically in parallel, with or without inter-bulb connectors, with no need for externally wired sockets between adjoining bulbs. Various fittings, connectors and supports are described.
