Awesome, I enjoyed the read. Thanks for sharing.
So each LED is getting 2A? Those elliptical TIRs seem like they work well in this application. Great beamshots too. :+1:
Super Awesome!
I planned to spend 200-300 but it came out to 500-600.
EVERYTHING came out wrong the first time and had to be done over at least once.
It took all winter, couldn’t finish in time for the spring desert trips, couldn’t stand waiting until the Fall so I went out to Calico last Friday night and back just to take pictures. It was 92 degrees at midnight.
Correct! Max drive current for the XP-G3.
Epic first post! Bravo!
Offroading looks like a fun way to get out in nature and a great way to mount powerful LED lights!
Are you also interested in powerful handheld lights?
Looking good !! 
What he said… 
What an amazing build. Reading through your post was enthralling. Thanks for taking the time to post it up and well done on a super effort. :+1:
Awesome project, congratulations !
I love the shape, minimalist design yet great functionality !
Did you have any problem with the russian drivers ?
I use on to feed my motorcycle auxiliary lights and find pretty reliable.
Amazing build! Love the slim form factor.
thank your for sharing this amazing first post. welcome to BLF!
Very epic build with great results 
You might want to take a look here. They top out at around four times that current.
Maybe a driver upgrade will be in the works 
Welcome to BLF!
Heatsinking would then be a problem…
I think that 2A is a good conservative choice
For sure, but a more capable driver with several output levels would be interesting.
…just keep the speed up on the highest level for forced cooling :sunglasses:
Wow I wish I’d seen that earlier! I didn’t know the spec’d drive current could be exceeded on a continuous operating basis. The drivers will go to 3A with a sense resistor change. The heat sink will probably be insufficient, but I’ll set up a test and find out. I might be looking at excessive losses in the 14ga 12ga wire from the battery too.
Yeah, you could probably increase that wire size several gauges higher, and go ahead and up the current to 3A max. Since you’re using DTP copper MCPCB’s I don’t think that would be a problem. But then again, I could be wrong. I’m looking forward to results from your testing! :partying_face:
Thanks for posting, build threads are the best 
That is pretty darn AWESOME.
Very nice work. You have plenty of heat sinking to drive those emitters pretty hard.
No. Build quality is good. All worked. I fried two playing with their PWM hookups, but that was my fault. I ordered three batches. Took about 4 weeks to deliver each time.
