Fascinating! I too have a ceiling fan where I replaced the four incandescent "calabra" lights with CFLs. They flickered. I redid the wiring thinking I must have screwed up the wiring when I put the ceiling fan in . . . but all wire nuts were in place as expected. Re did them anyway.

Still flickered and it is VERY distracting!

So I put one of the old incandescent bulbs back in - the flickering stopped.

I simply do not have an explanation . . . .

There is obviously an oscillation that occurs with the CFLs and a fixed resistance stops it. But why?
