My MTB schematic uses older Cree emitters running at 700mA, so there's no reason you couldn't substitute the new XR-E's or something. The Buckpuck comes in 350mA and 700mA flavours to suit your project. If you're coming from Luxeon-land, the only thing to watch is that the Crees generally have a higher forward voltage - 4.5V instead of 3.5V. This is part of why they claim "highest light output at 350mA" - the total input power is significantly higher.

Due to my work situation, most of my riding happens late at night anyway - so it's both unpleasantly hot *and* I need lights!

Thanks, and good luck!
