Quark X 123-2 with 18650 body

i was looking into this subject too and there are already enough CPF threads on it, very long informative for that matter. a week ago the Polish 4sevens site offered their last copy of the 18650 body.

well, a few of the points are correct, but the main reason to run an 18650 is:
less cost, WAY more power in cells.
Unfortunately the Quark is not allowed to be run with 2 CR123a Li-Ions ...

direct to the points:
* no reverse protection --> does the original setup has one? :thinking:
* more screwing --> correct but not correct for changing battery (open at bezel, not at switch end) but the problem is the change between level 1 and 2 (with the tactical), because the additional threads of the 18650 body do loosen sometimes
* longer --> correct, adds just under 1 inch
* thinner tube --> is that anything important considering a QUARK???? I mean thats the reason to purchase one of them
* expensive --> no clue to that. Yes one has to purchase one for using one
* awkward --> dunno what to type, but definitly the original 2*CR123 setup is way nicer (and smaller)

To be honest, I just removed my 18650 from the quark "X" and the original short setup is much nicer (+ the much more safe "operation" without the additional threads and use it as safety light with the CR batts. But if I would like the output of the XM-L and its tint more, I possibly still would use with with the 18650.
At least I am constantly switching forth and back ever few days and am not sure

klingt gut

that's a pro in favour of quark stuff. the lego fun

Can you tell me if the 18650 body/setup on the "X" XM-L would work?

any thoughts on how difficult it may/may not be to find an 18650 body?

Thanks in advance!

1. yes, you are correct. the 18650 will work with the turbo x and many people use them that way.

2. 4sevens isnt making the 18650 body anymore, so they are harder to come by.

Thanks for al of the advice/info... much good information and points of view and I appreciate it. One last follow up question on the "stock" Quark X 123-2 that I have now... can I run a 17670 AW in the light, in place of the 2 AW 16340's that I run right now? I read that the 17670 is maybe just a bit thicker around than the 16340's but on a different thread I was reading, it seemed that someone had successfully used the 17670 in a Quark body. Was a bit unclear when I read it, so figured I'd throw it on this thread and spell it out clearly. Thanks again for the help

The Quark 123 2 can run on voltages from 3 - 9 v. It can run on 2 RCR 123 batteries.

Definitely seems to be accurate... I'm currently and have been running my Quark X 123-2 on AW RCR 123's for a few weeks without any issues. I am still curious about my last question; can the 123-2 use an AW 17670 in place of the 2 RCR 123's? thanks in advance if anyone can comment on this.

I run my Quark X on an AW1760. Works fine. According to some of the reviews the Quark X will get brighter on 2 CR123 cells, but I can't tell the difference with my eyes. It's still very bright. I went 17670 for the longer runtime over the 2 RCR combination.
