Abstract
A mechanism for locking a fluorescent lamp adaptor to a standard incandescent screw-in lamp socket utilizing base member having a bottom and wall portions. The wall portion of the base member possesses an inner surface and an outer surface and an aperture extends through the wall portion. A male screw-in element is also utilized and is confined to the base member for freely rotating relative to the base member and the screw-in lamp socket. A tool urges the threaded male screw-in element into threading engagement with the standard screw-in lamp socket to permit insertion and removal of the lamp adaptor in relation to the standard screw-in lamp socket.
