THe XYL replaced the incandescent bulbs in our living room fan with CFL's. That 
didn't work too well - after a couple minutes, they started strobing on and 
off. It turns out that the fan uses some circuitry to keep regular bulbs from 
burning out, it brings the voltage up slowly, and the fluorescents must hate 

In out kitchen, we have two fans, with CFL's in each. These ones work just 
fine, but the particular bulbs we have in them now take too long to come to 
full brightness - around a minute. But the light fixture in those fans takes 
the smaller base bulb, so there selection is limited.

The Hallway to my office has a fan with CFL's, and it's been going for some 3 
years now with no problem. 

Each fixture has the bulbs upside down and at an angle, but I don't think 
that's been harming anything.

She also snuck in a CFL lamp  in the shack. That one is sitting two feet from 
my radio, and tests show no  interference from it. I used both my ears and a 
waterfall display from a sound card program.

I also have enjoyed this thread. The good news is that we are getting a lot of 
comparison points. The not so good is that they are all over the place 
regarding noise, warmup, and cold weather operation.

Is anyone keeping track of all this?
