Originally posted by Hypocorism Your take on that sounds quite logical to me. This might even be a good omen for encouraging more people to abandon their remaining legacy tungsten in interests of global warming too. So can't be all bad.
Actually, my brother has been testing various lights under a spectrometer recently for the purpose of setting up lighting conditions in a lab. He tested a couple CFL's because a colleague was curious.
Even a "full-spectrum" CFL basically uses three phosphors, meaning three primary wavelengths of light are emitted. The light is not white or beige or whatever approximation -- it's red, green, and blue mixed together. This could potentially make certain colours look a bit off, especially when photographed. Then there's the fact that they're hazardous waste.
Tungsten? Sure, it's warm (to the red end of the spectrum), but it's a fairly even curve across the spectrum, at least.
I've actually got a bunch of CFLs here at home. It's just a couple fixtures on dimmers that I use incandescents for, but I switched them to some new higher-efficiency halogens. I really like them.
