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

All comments welcome!
