I’ll take one as long as it stays close to the original design and not get super complicated with several switches and a UI that requires a book or flow chart. I want to be able to turn it on (and it be bright) and off easily.
Thanks !!
OP updated.
And I like the idea to follow this up with a smaller baby (AA and 14500 cell) version when all goes well very much!
We should have a good relationship with the manufacterer/seller by then. But lets start here 
And seeing how other groupbuys go, this may take some time, do not expect it in your hand anytime soon.
Could there be a ramping driver with this UI:
O 1 click on (on memorized brightness)
O double click hold second click ramping up from moon to turbo, release when brightness of choice is reached.
O triple click hold third click ramping down from turbo to moon, release when brightness of choice is reached.
This sounds like an awesome UI don’t you think?
I’m in for one at least!! Sounds great
You guys are right! What was I thinking? Make it 4S AA for Eneloops! In fact, a buck driver that could handle up to 4S Li-Ion would cover us, wouldn’t it?
easier:
*click for on (on memorised brightness)
*click for off
*when on: hold for ramp up, release when brightness is there
*when on: click-hold for ramp down, release when brightness is there
(this is the simple white part of the further very extended DrJones RGBW UI, works easy and intuitively, this is also how my Photon micro works)
If this came into being, I would do the large one but would do the baby one in a heartbeat!
Well start with the 18650 and hopefully make a baby after that.
We can’t put an little orphan onto this world now can we
How about choosing a ramping driver? Simple to operate, infinite brightness levels so ideal setting for all occasions and users.
Would it be possible to operate this on 3 rather than 4 18650 cells to reduce the weight a bit?
I’m in.
Interested in one depending on price.
2 requests:
- An option for Host only. Would be attractive to those of use loaded with drivers and emitters.
- Battery tube extensions. So many folks would love to make their SRK’s 2S4P, 3S4P, even 4S4P! The mod options would become endless. Especially, if the tubes could also fit the TK61 and TK75 (The TK tubes fit the M6, but not the other way around).
I’m in for 1 at least.
Prefer no lighted tailcap, have enough of them now.
Well, it would technically be possible to run it off just one 18650, since they run in parallel. You can put any number you want 1 - 4 into yours.
Ramping function sounds neat for fine-tuning, but sometimes I’m in a hurry. 
Can we still have direct access to a few well-spaced modes from both on and off states?
Highly interested!
interested but there is klarus g30 and thorfire s70 on the way so i kinda tight budget this month :person_facepalming:
how about 3x emitter 3x c3ll (1-3) form factor?
Very much interested !
Interested.
Always wanted a srk sized light.
Interested, in both this version and the baby one. I really like the above described UI. While I like TK’s UI on the A6 and X6/X5, it can be a challenge to quickly describe it to someone when they are using the light momentarily. “Click on, click off, click and hold to ramp it up or down.” is pretty obvious. Without actually showing a noob, “short half press” and “long half press” don’t really mean anything to them.
I am in for several of those depends of stats/price ofc, i would like to see some high binned HML/XPL emitters plus a ramping driver inside, or at least programmable
