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:
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.
Actually I think the vertical beam angle could be narrower. I’d like less light on the ground in front and more in the distance, so I bought some XQ-E Hi emitters to test. With the same lenses, they should get more Cd per lumen and the vertical should decrease from 13 to 8 degrees, per Carclo.
Man what a sweet build!
Welcome to BLF. I can’t explain how but someone reading here certainly can tell you how to set up your high beam vs. El Jefe shots either as an alternating GIF or even cooler is the hover-over trick so when you hover over it with your cursor it switches between high beams and El Jefe. It doesn’t matter if you do that or not it just sounds cool. Anyway, well done. I love the stealth factor. That straight on shot looking into it looks awesome. Looks literally like one solid bar of light. :+1:
This is truly awesome! I’ve been wanting to do some DIY lightbar for a while now with all the available options being extremely expensive or just plain crap.
Frankly I don’t think the $2000 light bars are all that either. Bling seems to be the primary goal over function. But then again, image is everything. No one would want to buy a plain black rectangle.
Good work mate you beat me to it. I’ve starting modding a small light bar for my girlfriends car. It’s 12 inches so it sits inside the bumper. Output aim in 10-15k lumens I was going to go crazy and use XHP70s but it will cost to much. I made my own heatsink also. I am not sure about where to mount my driver.
I am more worried durability then output I think.
The Carclo website has beam patterns for their lenses with practically every LED available. You can get lenses for the XM-L2 in spot, flood, or elliptical and design it how you want, for example: http://www.carclo-optics.com/optic-10003l25?opticfamily=20mm Once you find the pattern you want, you can get them from LED Supply or Mouser.
