Abstract: An adapter for connecting an LED light fixture to the threaded, screw-in socket of an Edison lamp holder. The adapter includes lever arms that toggle between a horizontal position and an inclined position. The inclined position of the lever arms poses a small outside diameter so the adapter can be inserted into the Edison socket without catching any of the socket threads. When fully seated inside the Edison socket, the lever arms are pushed into the horizontal position. A central core translating within the shell when pushed to the top position inside the shell locks the lever arms in the horizontal position. The lever arms when locked in the horizontal position define an outsider diameter larger than the internal diameter of the Edison socket to wedge the adapter therein.
