Hi guys.
I want to make a nice headlamp with a LED like the Cree® XLamp® CMA1516 LED or similar. Any tips on where to get this kind of driver that has low - medium and high setting, and can handle this kind of power?
(any other LED chip tips are also appreciated)
I want to make a head lamp with active cooling with a small waterproof fan that can keep it cool when the temps get high.

Thanks.

Okay, I'll ask it. Why this LED?
If I read the specs correctly, for a 4K color temp version, running at 35 volts, you get 1,700 lumens? That is easy enough done with a triple XPL-Hi, running from a single 18650 at 3.7v. If long runtime is what you are after, you can still run a battery pack in parallel, and use 3 or 4 18650's.
