Check this out! They're still expensive, but LEDs are slowly but surely making their way into the marketplace.
Here's my comment on the article:
As fluorescents (including CFLs) trigger vicious migraines for me and many other migraineurs, I can say I've been anxiously awaiting the arrival of household-use LEDs for quite awhile. I can't wait to use a bulb that will [at least soon] be even more energy efficient than any fluorescent bulb--and no pesky mercury worries and no barely-discernible flickering that'll trigger migraine attacks. Hallelujah!
