Abstract: A sleeve type lamp stabilizer that is made so that it will fit over a lamp socket, to be rigidly held in place with respect to the socket. The stabilizer can be clamped to the socket or rigidly connected to the lamp housing which mounts the socket. The sleeve type stabilizer has pads that support the lamp at the lamp neck.
