Real tired of my halogen ceiling lights. Replace them with what?

[Article Accelerator]

We have had Sylvania or Phillips PAR20 halogens in ceiling pots for about 3 years. All are on dimmers. They are in use daily but none has burned out yet.

CFLs take several minutes to come up to full output, aren't dimmable, have generally ugly spectral characteristics, and have terrible color rendition indexes.
