Driver for 3 XHP70.2 led at 16v

CNCman · 2018-05-04T00:10:00.000Z

Is it possible to run 3 x XHP70.2 led’s with 8 x 21700 batteries and 4s2p 16v. And if so, where can I find a driver. I have been trying to read and learn about this, but I’m still new to building and modding. I have a plan for a build, but I need the electrical things in hand first. Any help would be great. You guy’s are so far ahead, I’m having trouble catching up.

I wonder if Haikelite would sell you the driver from the MT03. It may be worth contacting them and asking.

I have not tried to get a driver from Haikelite but I have tried to get a SMO reflector for a MT07 from Gearbest and they said no. But I will give it a shot, they may have more in inventory than they need. Thanks, didn’t think to try that.

They will probably send you the driver, if it’s the stock one, and if you ask to pay for it.

I have asked for the driver of the MT01 along with the stock reflector, and they have agreed to send me both for 15$ total, which was a good price for a 40$ light.

Also, CNCman, would you be willing to go the FET route?

Texas Ace has linear regulator+FET driver for the MT09R, and it is a beast. With 8x21700 and the FET driver, 3xXHP70.2s would be an absolute monster:

Texas_Ace MT09R Modding thread, 20k+ lumens, 80CRI, can start fires? Yes please. Want to Sell

Here is a video showing what this light is capable of after modding: [Texas Ace MT09R 22,000 lumen XHP70 2 260 watt monster light setting things on fire] Here is the cheat sheet for the GT, this driver is basically the same when it comes to the user interface, mostly back end changes since then. If you need an MT09R for me to mod, Terry is selling them here with a large discount since they currently do not have a driver. He can ship them directly to me for modding. https://hesa…

Or just take this driver from Lexel, but it is limited to 6000 lumens for the Haikelite MT07S, meaning at max of 8000-9000 lumens with a triple build:

Buck drivers with adjustable input and output voltages and current up to 8A selected parts for best efficiency The base price for the driver is 16€ 46/47.5mm cost 1€ more 20 and 22mm got pretty expensive Coilcraft XAL7070 inductor +3€ 2€ shipping worldwide from Germany with priority air mail optional tracking with 25€ insurance adds 4€ for very big orders I can add for 2€ per additional 100€ insurance The drivers use Anduril or older NarsilM Each driver gets calibrated for output curren…

Thanks BlueSwordM
I will pm Texas Ace this weekend with a diagram of what I’m wanting to build and get some advice if its possible.
Trying to place the 3 led’s at the center or as close as possible.
There is a serious thermal transfer problem I have been working on and I may be able to tackle it with a copper support and a lot of contact with the body and external cooling fins correctly placed. Not sure about the mass quantity of the copper, still a guess so far. I think its build-able but not clear on the electrical.

You asked Gearbest for Haikelite parts? I was recommending asking Haikelite for Haikelite parts. I wouldn’t expect dealers to have them, nor for Gearbest customer service to be helpful in any way, with anything.

BlueSwordM · 2018-05-04T18:55:56.000Z

Ah yes. Send a message to haikelite@yeah.net, they will respond.

For my case, Dave responded after a day.

That was a few weeks ago. Thought GearBest may be able to get parts since I purchased the MT07 from them.

I emailed Haikelite just after you suggested to.
