I'm a little late to the CFL discussion, but I can't resist comment. "So, Brian, tell us how you really feel..."
I think compact fluorescent lights are hideous bastardizations of the term "white light." Look at any of their visible spectra, or just look at them through a spectroscope. They are nothing but discrete lines arising from whatever pinch of metals put inside at a high pressure to try to broaden the linewidths a bit. The phosphorescent coatings on the glass add nothing to their light output; might as well be white paint. Whole bands of color are completely absent from their spectra.
When I hear the term CFL lighting, I think of motel rooms that haven't updated in a while.

Somewhat related sidebar. My mom used to say that we should only buy 60 watt incandescent bulbs because people look best when viewed under 60 watt incandescent bulbs.

I really can't distinguish most yellow-orange garnets but i've seen clean, saturated color stones which are really dazzling, whether they're being represented aa Malaya, spessartite, or Mandarin garnets. As for hessonite, I have a very clean stone that if opaque would be the color of polished metallic copper. it is really unique. A reported characteristic of hessonite I have observed in this stone is the "treacley" appearance under magnification. This is like what you see when you pour corn syrup (or treacle-molasses) into clean water and it refracts light to appear swirly until it is completely dissolved. By the way the garnet composition chart is a keeper- thanks!
