This Light Bulb Changer Head fits Recessed and Track Lighting bulbs. The Recessed and Track Lighting Bulb head is a suction cup design that attaches easily and securely to any smooth surface floodlight sized bulb and includes a string used to release the suction cup from the bulb. This head can be used on any smooth surface floodlight, but is specifically designed to remove a burned out bulb from inside of a recessed can type lighting fixture. This head fits the industry standard thread pattern found on 16 and 11 3-section aluminum poles as well as 11 3-section steel pole.
