I've been using CFL bulbs (and their small circline predescessors) for years now. I do it a little because it lowers my bill, a little because it's "greener," but mostly because I don't need to change them very often. In over five years, I think I've replaced 3 bulbs in my house, and I'd owned them for more years before that. Light quality is much improved from early models, and the flicker is gone thanks to more persistent phosphors. There are both dimmable and three-way versions of them as well. Guys like Thomas Edison were the closest thing I had to a "hero" growing up, but it's time to move on.
