An adapter for a conventional threaded electric light socket or the like having an external right hand threaded base for threading into a conventional socket. A locking tab on the base permits the adapter to be threaded into the socket and jams the threads of the socket to prevent its removal. The adapter has a cavity with an internal left hand thread for receiving an unconventional bulb or the like with a mating left hand threaded base. In one form, the adapter has a releasable lock structure for holding the adapter in the socket. A removal tool is used to release the lock structure to permit the adapter to be turned into and out of the socket.
