This socket extender from Leviton can permit the use of a compact fluorescent bulb in a socket in the compact fluorescent bulb otherwise might not fit. Screw the socket extender into the existing socket, and screw the light bulb into the socket extender. Having the extender between the original socket and the bulb will essentially move the bulb away from the original socket by 1 inch.
Typical fixtures in which a socket extender may be useful include deep recessed cans, in which use of an extender will push the bulb down toward the face of the can. Another typical use is with table lamps with harps, in which the bottom on the harp is too narrow to accomdate some compact fluorescent bulbs.
