Detailed lighting info here

[bulrush]

If you want detailed lighting info on all types of lamps, from flourescent, HID, LEDs, metal halide, compact flourescent, go here: http://members.misty.com/don/light.html

It does not really have any project info but has lots of info on failure rates, spectrums, color temperature of bulbs, and more.

I thought this might apply to aquariums and their lighting.
