Got 'em, like 'em, and don't have any other kind of lighting in the house anymore, except for the weird halogens over the bathroom vanity. It took a while for smaller ones that fit in tighter fixtures to appear on the market, but that was just the industry adapting to consumer needs. In my home office/studio I work all day under a ceiling fan/light with 3 of them in it without ill effects that I can discern.

Peace, Mooh.
