Want to build a triple-LED setup in my MR11 housing...

First off, thanks to all for ideas and inspiration. I butchered a 7-year-old Marwi helmet light and plopped a Cree Q5 in (courtesy the folks at Cutter), and I like it a lot:

So now I'm greedy, and want to turn a bar-mount light into a three-LED setup using http://www.cutter.com.au/proddetail.php?prod=cut790, another of Cutter's kits.

Problem is, I just found out that CDD1209 driver is 23mm diameter by 15mm depth, and I don't believe there to be space for that, the optics, the LED board, and even a rudimentary heatsink...

Is anyone aware of a driver that'll push 500-700mA, from a 12v source, across three 3W LEDs, while managing to be very small? I can probably just tack on a bit of copper foil to transfer heat directly to the housing from the LED PCB, but size really matters.

Put the driver in the battery pack.

I should have thought of that. I'll just pick up a lithium ion pack from batteryspace, with some shrink wrap and a couple trailtech connectors, and make a separate inline driver module. THANKS!

The Bflex will fit - Cutter optic, LED board, 32mm x 7mm aluminium slug heatsink with the bflex on the rear.

Finished the triple, bflex set to 350mA low 750mA high - whilst testing the thermal 50C trips after about 12 minutes in still 18C air whilst running at 750mA so should be fine outdoors.
