The LED chandelier bulbs can be installed into medium E26 screw base fixtures. These lights work perfect in my ceiling fans and my chandeliers. They are a great price and no problems. I use them in my ceiling fan in my bedroom. I use my computer and read in bed so the brightness is great. I'm sure I'll get used to them. The bedroom is now certainly bright enough to be used as a reading room.
