Popular Mechanics did a head-to-head test of one traditional incandescant bulb with 7 different types of Compact Fluorescents, with a lot of emphasis on light quality (both in terms of reading and recongnizing faces.)
Contrary to popular wisdom, the CFLs stomped. The incandescent Sylvania Double White Soft Light had the lowest quality light of those tested, it was “Much warmer” than the others, but yellow colors “appeared greenish,” while the Compact Fluorecscnts generally appeared to have higher light quality.
Go figure. It is easy being green… but you’re more likely to look green under an incandescent.
