Test report on some Luxeon-based lamps

[mfc]

Speleogroup (http://www.speleogroup.org) is
experimenting with circuits for driving high-power LED
devices, such as the Luxeon Star from Lumileds.

Earlier this month we tested a number of these lamps,
using various conversions and drives, in real caving
conditions in Spain.

I have just posted our subjective notes on the trials at
http://www.speleogroup.org/lampTest2003.html

All comments welcome!

Very nice work. Have you considered using blue and amber stars to get something close to white? Or would the two-color shadows be too distracting?
