I want to build myself an LED bike light using 3 XRE's. I already have a 6v battery pack from my old nite rider that I would like to use. I want to drive each LED at 500ma. I've been looking at converters and I am cofused on what they output. It sounds like you have an input voltage range, and it outputs a constant current. What is the output voltage? Does it matter? Will the Vf of the XRE's even matter if I use one of these converters?
