Usually that’s correct, I wouldn’t settle for that low of a current. But if the light impresses me and it’s difficult to repair or place the driver then I tend to play it safe and just enjoy the light. I’ve got plenty of hot rods and dragsters, sometimes it’s nice to just have a smooth ride. 
Output current reading, or input (a.k.a. tailcap), Dale?
Nice. Looks more comfortable to hold but it’s a tad bit larger, so maybe a bit less pocket-able:
JM35: 130mm x 55mm (length x head)
JM26: 142mm x 63.5mm
EDIT: Who sells the DQG tiny driver? And did you have to mod the driver in any way? you posted answers while I was typing!
hmmmm
if the 3 original LEDs are switched in parallel and get each 2A then the driver delivers 6A… (at 4V)
if they are in series it just boosts the Voltage up to 12V to get 2A over the led
am I right?
Yes you are, but a boost driver cannot work with LEDs that need less voltage that the cell has (LED in parallel, for that you need linear drivers or certain buck drivers)
According to the specs, it’s a 6A driver.
“3. Turbo mode up to 6A, 1250 lumens”
If my cell were fully charged it would probably be very close to 3A on the XHP-70, which of course is a 6V emitter, so that would be the equivalent of a 6A current to a 3V emitter, right?
Regardless, it works, and with a single cell to what is otherwise a dual cell emitter. So it’s magical, special, unique, and a winner. Beat the dead horse if you will, it’s not ALWAYS about maximum output. (I said that? really? I better go lay down for awhile….)
The original DQG Tiny Triple XP-G2 is wired in series, making the emitters need 9.xxV to run. And this is done through the single 26650 cell by this very large and complicated driver.
Edit: Sorry, I see what you did there. The boost driver has to push current to emitters that need a higher voltage than the power supply, hence “boost”. This is why they’re wired in series. Got it.
3V* 6A = 18W (parallel LEDs)
9V* 2A = 18W (series LEDs)
Same amount of power, which is all that matters.
It's boost driver, so you need to measure the output current of the driver, as the input need to be higher, because you have 6V at the LED but the input is 4.2V so the driver needs to use extra current to boost the voltage, thus input current is higher than output current on a boost driver. So that is why it is totally unlike a direct drive circuit or a linear circuit.
So a “boost” driver Steps up the voltage, resulting in lowered output current (vs input current) Reading this it sounds like the JM35 isn’t going to work on 2+ cells?
This is probably a dumb question i’m sure but are/were all MT-G2 emitters 6v? How does the driver work to put the correct voltage to the LED in multi cell MT-G2 lights, (for example the JM30 that can run on 2 or 3 cells)
Yes in essence, more current is drawn to boost the voltage.
That would mean the voltage is over that the LED requires, cannot be boosting, but of course that should result in burning the driver or nothing to happen if there is protection added.
Some MT-G2 are 9V, but I am not sure if any manufacturers uses those.
The driver does not put correct voltage, the driver puts constant current and the LED's voltage is maintained based on that current. If the input is ok with both 2 or 3cells then mostly likely the driver is buck.
I used 3 of the 9V MT-G2 in the BTU Shocker, with it’s 3 cell carrier. I figured the 3 cell configuration had too much current for the 6V emitter, overhead would be too far above, but with the 9V emitters and in 3 parallel it works out quite well.
The MT-G2 is offered in 6V, 9V and 36V.
Yes 36V also, I forgot about the 36V one since the voltage is so high it is quite non-flashlight friendly.
+2! 
I seriously considered the JM30 but the lack of a side switch and not being able to use one 26650 cell were the deal breakers for me. This really looks nice!
The Shadow JM35 has arrived to Banggood with MT-G2 or XHP-50 option for $49.95, although it isn’t expected to be actually in stock till 17th of May. I didn’t know it also had a tail switch as well, the Banggood page confuses me. Link here Banggood
interesting..
CNQG left, BG right.
Well, it looks like they haven taken up my idea do combine the head of the new JM35 with the batt. tube of the BTU STR1.
A normal switch for on/off and the side button for mode selection would be nice indeed.

Isn’t it the batt. tube of the JM30?
Or are those the same?
This is great, I guess that’s what the “upgrade” is? Now it will have a lockout switch for parasitic drain.
I think I will be getting this and the JM30 Body Extension Tube. I will make up a 26650 dummy battery because I like a longer handle for home use along with the option to convert to a shorty for pocket carry. So happy I waited and didn’t get the JM30, side switch and single cell option were the only things missing.
Now we just need M4DM4X to get us a discount code!
I do think that this is a clear case of lego……don’t have the JM30 but the batt tube of the STR1 looks exactly the same.

Bytheway: Me buying a JM35 will have to be postponed a little while because the “Wonderfull & Intelligent Financial Executive” (aka W.I.F.E.) has strongly advised me to postpone this due to the number of ongoing projects and recent purchases…… 
:_(
I’m in doubt of which one I should choose (the JM30 or JM35), I want to be able to use one and two batteries…
Anyone know yet if we will be able to use two 26650 batteris (with extension tube) in this one?
I am looking longingly at this Shadow JM35 (1xMTG2), or SL3 (3xXM-L2). Both available from Ric @ CNQG/EDC-Light.
Still undecided between these – any kind advice?!
Does anyone know if the SL-3 currently stocked by CNQG/EDC-Light is the very latest version, with the improved anodising and spring contact in the head? (As pictured here: https://www.fasttech.com/product/1359103-shadow-sl3-3-cree-xm-l2-4-mode-1800-lumen)
I have asked Ric by email but responses are sometimes quite slow. Nice guy and shop to do business with though so far.
Currently waiting to see if M4D M4X might be able to get a code - if so could justify getting the JM35 from BangGood instead…
