Been working on a new driver for higher powered LEDs. It's a buck converter and has a nominal 8 - 24V input range.
Output is up to 16V and so far I've tested it at up to 2A output driving a 6V load (a Lamina Red BL2000) for a few hours.
I'll be cranking it up a bit beyond that soon. It is fully current regulated and dimmable via an onboard trimpot or external pot (similar to Fatman).
Here's a pic of a prototype next to a Star for size comparison.
And a pic of another proto driving a BL2000 at 2A. The BL2000 IS bright - the camera shuttering down to 1/200 sec ISO 100 /ubbthreads/images/graemlins/grin.gif
