Options for lighting are getting more interesting - which means more complicated

From Earle Rich: I check out the Oil Drum blog infrequently but my latest reading led to a very interesting discussion of lighting from a scientific point of view. The most common rating of light output from any type of device is the lumen. Turns out to be the just the start for the investigation of various lighting options.
There are lots of photos and charts showing how lighting color is such a tricky thing to produce. CFL and LED lighting is certainly the way to go for efficiency but there are many other factors to consider as well.
As a photographer, color accuracy is important. When I take photos inside with flourescent or mixed lighting sources, I have the chore of trying to bring the color back to something like neutral. Taking a photo of a gray card or something white helps but almost never do I get a natural appearance. Acceptable is about as good as it gets. My job isn't likely to get any easier as the choices for lighting get even wider.
If you read the Oil Drum article, please be sure to scroll down to the comments. Those are even more interesting.
