I have several can shaped lamps where the recessed bulb is so close to the wall of the lamp that I can't grab it. This makes it difficult to remove the lamps or, when replacing them, to insert the lamp base into the socket. So although I can get to the lights (without an extension cord), this device has made changing bulbs a lot easier. (However, I would suggest spraying the base of the WD-40 lamp before inserting it to make it easier to remove later, and to avoid the end of the lampโฆ
