For whoever is interested.
A few weeks ago I bought this driver to see if it will power an mtg2 from 1 cell.

Initial test was a success. A few weeks later, I see kd have a range of xhp drivers based on the original one I bought.

Is this the same driver?
US $10.71 / piece

I think yes, they are all drivers from Fei Long, the specification looks interesting but not sure about their stability though.
For one thing the driver is too large for most lights, which is 26mm in diameter.
I also like the short version with one cell for pocketability, however I thought it would be nice to also have the option of running 2 and 3 cell configuration for extended runtime, and for when I donāt need to pocket it.
Looking at the JM30 photo below, it seems a little too short in hand with the large head it has.
Mainly I want the side switch, too bad the JM30 doesnāt have a side switch.

without the extension tube is too short in my opinionā¦
nice size!
Also wish this had knurling instead of the ribbed design, love me some good knurling.
Like Shadow used to do.:heart_eyes:
I got the very nice looking Shadow JM26 some months back. Also bought driver for the DQG Tiny. With that driver, I was able to put the MT-G2 into the JM26 and run a single 26650 to the big emitter. Very nice light, and yes, unique running a 6V emitter off a 4.2V cell.
Very quickly became a favorite. 
To me that looks more appealing than the jm35. What is the beam profile like?
do you have more info about the driver you used?
I dunno if its my luck or anything, but back in 2013 i bought SHADOW JM26 from FTā¦.and wasnt that happy, i could see the PWM in lower modes, the body had minor scratches and the reflector came kinda dusty( you know how hard is to manage reflectors)ā¦and as far as i can remember it was 55$+
Currently i am using Y3 with LD1 driver as my offhand torch for hunting, got also modded MTG2 with a single 26650 and that Aliexpress driver
Also Dale, did you have to modify the reflector?
Dale, I am also interested in the driver you used. Do you have a source?
These are the same āmonsterā driver for TR-J 12/18 back then
The driver is the one for the DQG Tiny, the triple with 26650 thatās so small. They sell it separately. I did have to remove the e-switch and swap it over I think, as the new driver didnāt come with one installed.
I merely cut a small place for the corners of the larger die substrate, removing the very minimum from the reflector base. After the XHP-70ās came out, I put one of those in this light in place of the MT-G2.
My JM26 is nice, very well finished and clean as a whistle. I like itās style, am still thinking about putting a kill switch in the tail for lockout as it DOES have a drain that will sap the big cell over time.
My memory is worse than I realized, checking my order history with CNQG I ordered that light and driver on Christmas Day last year. 
It is a 2A boost driver ( meaning MT-G2 will get 2A output at 6V from 3.6-4.2V input source). So of course it is is not a 6A boost output as the title implies, I guess it was specified/targeted towards people who are are not familiar with step up and step down drivers, but with linear drivers. But well, I am talking only based on specs, I mean what makes the specs accurate? only testing the output current for various LED voltages 6V, 9V, 12V.
It is 2A(*3) on turbo. Designed to give 2 amps to each emitter on a triple setup. So it will give 6 amps to a single emitter in turbo mode give or take.
Am I way off here? Seeing some of Daleās flashlights, I seriously doubt he would settle for 2A in a Xhp70
Yes you are way off, see what I wrote above.
I just took a current reading with a Gold King Kong 4000mAh cell and got 2.67A. I donāt think I did anything to bump the output, but thatās asking a lot of my memory if I did that 5 months ago.
Usually thatās correct, I wouldnāt settle for that low of a current. But if the light impresses me and itās difficult to repair or place the driver then I tend to play it safe and just enjoy the light. Iāve got plenty of hot rods and dragsters, sometimes itās nice to just have a smooth ride.
Output current reading, or input (a.k.a. tailcap), Dale?
