I am trying to replace a switch in my home and thought if i put up a dimmable switch, will it be able to control the light bulb's brightness?
Does all bulbs work with dimmable switches?

A few compact flourescent lamps can be dimmed with a standard dimmer, but the great majority can not.
AFAIK all incandescents can be dimmed, I have never seen one that cant be.

According to Canada AM : Consumer Alert dimmable CFLs do not work very well. They go from off to full on with just a small nudge on the dimmer knob. The dimmable range is not 0-100% like an incandescent bulb but smaller. They just do not go 
like regular CFLs.
There are dimmable LED bulbs as well but I suspect similar problems as with dimmable CFLs.

I read this earlier in the month and these are soon to be available for cheap. Looks good unless you need super intense lighting, don't know why you would...

I'm currently testing dimmable CFL's to replace a bunch of R30/PAR30 halogens.
The Global Consumer Products ("Overdrive") Dimmable 5000K 15W/65Wequiv R30 A) sticks out beyond the can, B) advertises only 43 lumens/watt, C) takes a little while to warm up, D) doesn't do a cold start to minimum brightness, E) sometimes cuts out if you dim it too fast, and F) produced a nice, clean white light. 2 year warranty... _not_ Energy Star.
The Neptun 5000K Dimmable 18W/75Wequiv standard A) sticks out beyond the can a little (and is a regular bare twisty CFL), B) advertises 61 lumens/watt (and is indeed visibly brighter), C) comes on immediately D) cold starts immediately to minimum brightness, E) does not cut out, and F) also produced a nice, clean white light. 2 year warranty, and it is Energy Star.
Others to be tested when they arrive, but so far the slightly more expensive ($11.xx vs $9.xx from 1000bulbs.com) Neptun is winning. The Neptun also had less dire warnings on the instructions than the Global did.
Neither one dims nearly as much as an incandescent. The Neptun dims about as far as the Global... despite starting off significantly brighter (almost twice the lumens).
