Two problems I see with using an MT-G2 in this light are the fact that you can't get the reflector low enough, to get the tightest spot and that the switch is really only rated to about 1.5 amps. Both of these issues make for a harder to mod light. For those of you who do not have the experience, you might want to just put in an XM-L2 on the original star and put in a driver like the Qlite and let it go at that. It will still be an increase over the stock light and you could add a few chips to the Qlite, but I would stay below 5 amps with it.
For the rest... It's a lot of work to get there.

The first video is just a tear down of the light.
The next videos will be on the modding of the light for an MT-G2 and possibly an XM-L2

This video is one "one way" to fill the hollow pill.
There are other easier ways, including just leaving the pill alone and using a copper star. I imagine most will do that, but if you want more mass, then some method of filling the pill would be good. That can range from finding a small piece of aluminum or copper rod, to having a shop make an insert for you. Just cutting some copper discs to go inside under the stock shelf is probably another easy way. The way in this video is harder, but it's just the way I will be doing it for this particular light. The other lights coming will be done differently and I will show them when they get here.

This video is about the led/reflector issues with this light and an MT-G2
The problem is really about the fact that this light uses a 25mm star and the reflector base is made for that size star, so when we use a 20mm star, there are lots of clearance problems to deal with. It is less so for an XM series led, but the MT series needs to have the reflector down farther, to help focus.

Switching from Parallel to Serial batteries with the ZY-T08
Fairly long video on how I switched from parallel to series batteries, for the MT-G2 mod.
------------------------------------------------------------------------------------
I just can't let that switch alone. I will be putting a Judco 10 amp in it.
I will do a video of it, but I will be using copper sheet, to make a spacer, to fit the bigger Judco in the tail of the light.

I replaced the stock switch with a Judco 10 amp. It took a long time and a lot of work. The video is long, too long, but that's how it is.
After doing all this, I would highly recommend staying with the stock star and reflowing an XM-L2 on it. Then just add some Copper discs under the star and leave it at that. It would be a LOT easier all the way around and I don't care for the beam of the MT-G2 in such a small reflector. The MT-G2 needs to be in a bigger diameter reflector, like the ZY T20 or a similar large reflector, 4x18650 light.
If you do the MT-G2 in this light, stick to about 3 amps and use a Qlite driver.
The FET driver did not work well here. I could not get above 3 amps with 20R batteries. I do not know why, but I plan to stick with the 7135 based drivers. At least I know the results of them and it's too much time and effort wasted, (personal opinion), with the FET driver.
Beam Shots:
Remember, it's only about 3 amps, less than one third of what it was supposed to be.
The four shots above are the 4 modes.

That's all folks...
