I'd suggest anyone in doubt should hit google for the current range of products. I was mighty suprised at how they have advanced in the last few years. There are kinds for an amazing number of fittings now, and even B&Q/Homebase have a decent selection available.
> What bulbs will be used in dimmers?
There are dimmable energy efficient bulbs available now, although I've only seen them from one company so I do wonder if they have a patent (and thus, a massive cash cow)
These ones will provide dimmable bulbs that don't require a dimmer switch, so can be put into an existing non-dimmable lamp (say, for instance to leave a bathroom light on a 5% overnight when you have guests or children)

and there are dimmable versions that work with traditional dimmer switches too

(Note: I'm not connected with the company, I've just used them and found them to work really well).
There are also energy efficient bulbs to replace many (240V) halogen spots, commonly found in kitchens etc. They are wider at the plug end, so it depends more on whether the lamp fitting is big enough to take them.
The only bulbs I've been unable to convert to energy efficient ones in our house are the 12V halogen "spot" bulbs and the 500W floodlight halogens outside the house. There are LED varients of the 12V type, but the brightness is not there yet (but it will be soon enough).
I too was of the opinion that the energy efficient bulbs were slow to start, tended to flicker on, and took time to warm up. But I was wrong - the more recent versions are stunningly good.
