As a matter of interest, I am currently looking for an ultrabright LED solution for a powerful light. I am busy making an underwater torch for scuba diving, and if I am happy with the solution, I would like to make my KR2 landing light the same way.
I just called the main LED supplier in France; their best offer is a 3x1W dichroic bulb, 150 Lumen (direct replacement for a halogen spotlight); it comes complete with a converter / filter to protect the LEDs against transients. Trouble is, they want $ 130 for each unit, and that's way beyond my budget. Is that a true market prices, or are they trying to rip me off? Serge Vidal KR2 "Kilimanjaro Cloud" Paris, France
