BBC Guide to Low Energy Lighting
 

I saw a presentation at the BVE in London a couple of months back, about how they're converting studios to run on low energy lights. There's a PDF available that includes the spectrum curves for various alternatives. Best of all it's free.

Apologies if this has been posted before.
