I first bought a whole set of these with three different sized fittings and a support from our local hardware store. However I really only needed one size of lamp changer so I returned the kit and bought this one. There were no individual sizes in our hardware store, just a set. The lamp changer can be easily screwed onto our telescopic rod. Turning the screw on the changer will keep it from coming out when you try to screw in the bulb. I was able to easily remove the mini CFLs from our 20 foot tall ceiling fan. Installing the LED replacement was a bit tricky. The lamps have a candelabra base and it was not easy to hold the post and insert the bulb into the socket which was well below the fan lamp. A couple of times I really had to adjust the position of the bulb in the holder as it doesn't hold the bulbs very well. When this job is done, I probably won't need them for many years, assuming the LED bulbs meet the longevity requirements.
