Are you referring to the spectrum, because color rendition has been greatly improved. Tubes are sold with a CRI (Color Rendition Index), and finding a cheap tube with a high number is pretty easy these days.
Yes, they're improved, but still nowhere good enough. They're bad for your eyes.
I use florescents far more than most do, but we have to admit their limitations. This bill is a really bad idea.
Are there any web sites that show the actual spectra of different fluorescent units? Not sure how the CRI is computed, but I would think it difficult to resolve spectral quality down to a single number (since different applications would attach different levels of importance to different characteristics).
