We get this question fairly often: in what lamps and fixtures can I use CFL bulbs? The answer is simple - any incandescent fixture or lamp that will accommodate a CFL bulb can be switched out.
Most CFL bulbs fit into most sockets, the exception being some table lamps where the larger CFL bulbs won't fit under the shade harp.
One thing to remember - if you have a table, floor lamp or light fixture with a dimmer feature we recommed a dimmable CFL bulb. This will prevent burning out the non-dimmable CFL bulb prematurely.
So swap out those bulbs and start saving money!
