I went looking for information on dimmable CFLs - I have just worked out how to take the cover off the slow start dimmable light fitting in the lounge and it has two filament bulbs - and so far haven't found much.
However I did find
"There have been reports of the government seriously intending to ban filament lightbulbs. If this plan goes ahead, there may be compatibility issues with non-filament types of lighting and dimmers. For DIYers this may be a minor matter, most can replace dimmers with switches, but for the less DIY able, hiring an electrician may prove an unwanted expense.
Some are considering stockpiling filament bulbs as a way to circumvent this issue. "
So last year, my dear ;-)
I can also see Google hits for dimmable CFLs - do I assume that if a CFL does not speciffically state that it is dimmable then it isn't? A Wiki update would be most welcome. [I know, DIY.....but I'm not spakryfied enough to update the entry.]
Cheers
