Abstract
An adaptor for extending tombstone style lamp sockets, as used with fluorescent lamps to permit the use of shorter lamps. The adaptors include pins which are rotated into the standard tombstone style socket and then further include contact openings in a plunger plate movable in a direction along the longitudinal axis of the fluorescent lamp to permit insertion of a fluorescent lamp without the need for rotating it into the tombstone socket.
