OLEDs and LEDs however still don't have a CRI that matches that of a nice incandescent light. There is much to-do in the theater world about when LED light sources will be able to take over the venerable HPL and other tungsten sources, and the ability to accurately light color is a major stopping point.

That's always been my issue, too. Even CFLs aren't great, and those don't dim. I started following another technology a few years back called ESL (Electron Stimulated Luminescence) which is basically a TV turned into a light bulb. The company finally started shipping stuff earlier this year and I got my hands on 2 of them. The light quality is really nice, and they dim quite well (although not as low as I'd like). It only puts out ~30 lumens/Watt. That makes their 19W bulb around 600 lumens and can reasonably replace 50-60W incandescent. Check out http://www.vu1corporation.com/ http://www.vu1corporation.com/ as far as I know they're the only company making ESL. I am not sure if their tech has the ability to scale up in terms of power or efficiency. It's a tiny company compared to the scale of those working on LED/OLED.
