We switched to compact flourescant lightbulbs 2 years and I love them: Every bit as bright as the bulbs they replace, yet consume only a quarter the power. All the ones I bought originally are still working, and we've definately had lower electricty bills since we started using them. Most of the ones we bought have a warm, yellowish glow like incandecant bulbs: Everyone here thinks white or bluish-white is too harsh for indoor use, so we only use those outside. A few light fixtures still use incandescants, for a variety of reasons, some because of dimmers (I havn't been able to find any dimmer compatible CFLs in my area), and second because some CFLs are to large for fixtures, but now that has changed, thanks to more compact CFLs now available:
Left: regular incandescant bulb, Center: new, more compact 13-watt (60-watt equivilent) CFL, Right: regular 13-watt CFL.
