I overstated the case a bit when I said that CFLs are not dimmable, and Ed Reid helpfully pointed out Noli Control dimmable can lighting CFLs in his comment on my previous post about CFLs and policy. See also the the dimmable CFLs page at 1000bulbs.com.
I amend my claim thusly: they are technically dimmable, although not over the same wide range, as Buzzcut noted in his comment on the post. The state of the technology has required timers, converters, adapters, etc. to achieve dimming in the past.
These newer technologies appear to have gotten around some of those limitations, although I can’t comment on them specifically since I haven’t used them. I’m also not persuaded that the dimmable chandelier bulbs will fit in my chandelier without poking out over the top of the shades (which drives me crazy about the CFLs I have in lamps at home). But a year from now, when we’re done with our house renovation and have around 30 can lights, 3 pendants, and our chandelier, I’ll install dimmable CFLs in them and report back to you on their quality.
