The problem is that comparing a spectrum isn't actually meaningful. I really don't care about the spectral shape of the light if it's not perceptible to me. You want some sort of quantitative estimate of what you care about.
- nostromo 10y agoIf you're looking at a white piece of paper with black text, you won't be able to tell the difference. But if you're looking at color (flowers, a painting, human skin) then spectral shape becomes very important. Look at all of the shades of color you're not seeing under a typical CFL: http://www.bealecorner.org/best/measure/cf-spectrum/spectrum-9-07a.png http://www.bealecorner.org/best/measure/cf-spectrum/spectrum...
- lutorm 10y agoI'm not disputing the fact that there is a difference. But whether it's perceptible depends on where in the spectrum the differences are in relation to what you are looking at and the response curves of your cones. Not to mention your expectations. I'm a pretty picky person when it comes to color when working with photos. But I don't have a single incandescent in my house and I can't even remember the time when I've been bothered by not being able to discriminate colors.
