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. The need for support results from the common practice to provide a small amount of clearance between the lamp socket and the mating base of the lamp to insure that the lamp will not corrode in place or otherwise become stuck in its socket when it is time to replace the lamp with present large lamps. This slight amount of play in the socket translates into a large amount of movement at the opposite end of the lamp and thus the independent support stabilizes the lamp, and prevents mechanical vibrations from prematurely causing lamp failure.
