I'm guessing that our experience with CFL's is like that of a lot of people - some very good, some not so good. On balance, however, the energy savings is so significant that I can't understand why anyone would continue to use incandescents.
The good has been that the life expectancy has been as advertised, and the savings have been as well. We've switched out just about every bulb we could for CFLs, and we knocked about a third off of our electric bill.
We've also been able to find a fair number of decorative options, such as globes for above the vanities and a good dimmable for our hanging lamp above the kitchen table.
The not so good are in dimmables generally, particularly for speciality fixtures like ceiling fans. We have a vaulted ceiling in our family room that has four light sconces on it, and is dimmable, and finding dimmables bright enough for a room that size but small enough to fit those sconces has been a real challenge. We face a similar circumstance in our dining room with our dimmable chandelier.
I know, however, that the market is evolving and more CFL options are appearing almost daily. I've regularly used a couple of Web sites for some of the speciality bulbs, but more and more the big retailers, Wal-Mart and Home Depot, especially, are adding to their CFL stock.
