Great mod as always 4wheeler.
MT-G2 can handle this angry driver?
Thank you zeremefico. Yes, the driver seems well matched for the MT-G2 using 3S or 4S cells. I think it's wise to augment the heat sinking on the large diode and voltage sense resistors though.
Awesome, looking forward towards the results.
10A to the emitter sure does sound like fun. 
Thank you Ryan. How is college going for you bro?
College is pretty awesome so far, thanks for asking.
The workload has been steadily increasing for the two weeks but still is manageable.
I’m looking forward to trying out the machine shop equipment and perhaps make my own light.
I've always thought the 7G10 would be a great light to mod into a beast. It's great to see you doing it. Can't wait to see your finished results! :D
Thanks Johnny. Hoping for a good result.
The spill area my be a bit narrow for my taste, but I hope not because the reflector looks so cool to me. If it is too narrow, I could always swap in a shallower 80ish mm reflector and beef up the heat sink even more.

The +B spring is very Thin , maybe You would change or add solder wire.

Thanks Pok. Totally agree with you.
What a shame to see such a poorly put together light from a know manufacturer. Your mods are looking good. It should leave the stock light for dead.
True, but it does provide an opportunity to have a real nice light for a good price to a modder.
Thank you MRsDNF.
This looks like a fun mod. Makes me wish I had one, but I’m over my head in the modding of drivers and firmware department. I’ll be keeping my eye on this mod.
I always thought MTGs liked to be higher up in the reflector?
You’ve probably got it al figured out, but I picked up a couple of These 26mm MCPCBs incase I come across one of those wide flat bottom reflectors.
So far you seem to have become the King of the souped up HX1175B driver. I’ve not yet driven an MT-G2 past 7A. I definitely want to see the copper work in the pill as you put it all together.
Thanks Ouchy. I'm no focus expert. So I could be wrong. I should also say that I have dedomed very single MT-G2 that I've put in a light. I think that makes focus more critical because it significantly reduces the apparent emission surface.
Those bases sound real good. Over an inch in diameter. Also looks like the copper is flush with the top of the MCPCB. Both are the main reasons I go through the trouble of rolling my own. Definitely worth the price. I will be ordering at least a couple of those too. Thanks for reporting them.
I have only used the HX-1175b with hardy MT-G2's. RMM has sacrificed scores of xml's in an attempt to tame the driver for broader applications. For that reason, I gladly pass my crown to him.
I have finally got back to the light and have it mostly completed. OP updated and beam shots added.
What a performer. Great mod. Making that copper star thingy yourself is wicked! It would take me forever I think. Great writeup too and I love all the mouseovers. TY for sharing.
Thanks Ledsmoke. That copper star did take me a lot of time. I learned from it, but don't see using that approach again. Will try something different next time that I hope is easier.
EDIT: I should add that this light would be easy to mod with just a Noctigon and driver swap. I just wanted to try some stuff out. OP updated with more info. Probably won't be doing much to this light for now. I'm starting an ECU build and swap for one of my cars.
What an amazing effort. I admire your electronic work and metal working. The result was well worth it going by your pictures. Thanks for sharing.
Edit, As far as I'm aware there are no isolators available for the MTG led.
Thank you very much MRsDNF.
Seems like a good business opportunity, those MT-G2 isolators. Any vendors listening?
Nice photo!
Great mod and write-up!
Which of your (modified) MT-G2 lights are your favorite?
