This is the way i use my Quark 2x123 Turbo too and it's the perfect thing for me. I actually carry a spare 17670 battery in a spare 2x123 turbo body with clip and tailcap so it's a twenty second job to swap tubes but I have never actually run my 16760 down to the point where I needed to swap.Looks like the 123^2 head is better with 17670 than a 123 or AA head. It won't leave you in the dark w/o warning.
My favorite light has to be the Q123^2 neutral with a 17670.
I don't see the point of the 18650 body as I assume it is a bit thicker and the 17670 never gets close to running out of juice. .....
Is the 18650 tube much thicker? Can it use 2xRCR123 like the original?
The voltage of an 18650 will disappoint you for time in regulation if you're using a 123^2 head. It's meant for the AA or 123 heads.
Looks like the 123^2 head is better with 17670 than a 123 or AA head. It won't leave you in the dark w/o warning. The brightness should be almost the same as the 123/AA head with a 3.7 volt battery, but will run for waaaaay longer.

I use mine at work as a paramedic and even in a difficult extraction call we are never on scene for more than 45 min or an hour. I keep a Q123 body with a CR123 primary in it for backup and have an Olight M20 with an extra 2x123 battery magazine just in case I run out or my partner needs a light.

Now I'm curious how much runtime the 18650 has over the 17670. Anyone know?
The AW 17670 battery fits into the existing standard 2 x 123 tube. Some Quark tubes are narrower than others and I've found a couple of mine are tighter fit than the others but even my tightest ones were cured by removing the chrome sticker off the AW battery.Does the 17670 fit into the body of the 123², is it the same size?
you can find the runtimes of both primaries and 17670 in both the low voltage and the high voltage heads within Selfbuilt's thread called "4sevens Quark round-up review"I was trying to look at the cost and benefits of which Quark to go with over the runtime and lumens it will give me and whether I'd need to get the extra body.
How long does the 17670 last for on max before running out? Is it more than primaries?
I use 17670 on the AA head as well and it still runs on AA also. The AA head is designed to take up to 4.2 volts so it's perfectly safe with 17670 and 18650, the only issue being that on AW batteries according to the graphs it runs regulated brightness until battery protection suddenly cuts it off unlike the 2x123 head which tapers down somewhat. I do remember a thread where the torch wouldn't work on AA after 18650 but the problem ended up because the tube was put on backwards and had connectivity issues due to anodising.I have read a post from someone who said they used a 17670 or 18650 in their AA head and since then it is the only battery that works the AA no longer works. Seems strange.
Did someone say that? What do you mean by efficient?im a little confused,
are you saying that a 123-2 with a 17670 is more efficient than a 123 w/18650?
if a 123-2 w17670 burns as long as, or very close to a 123 w18650+body
You've nothing to apologise for, you just asked a question that needed clarification.wow thank you
i apologize for being un informed and jerking up this thread
i was trying to understand this comparison and side stepped it
to conclude
is a quark 123 w/18650 is the run time/ brightest king of quarks?
You've nothing to apologise for, you just asked a question that needed clarification.
Just to clarify, the 18650 in a 2x123 head should be no brighter than the 17670 until the 17670 starts to fall off. In the aa/123 head it should be no brighter at all until the 17670 actually goes dark (since they will both run a flat regulated line at the same voltage).
I stand by my earlier bush mathematician's guess that the 18650 will run somewhere near one and a half times as long as the 17670 so yes, in effect it is the king but my personal view is that unless there is a specialist need for the extra run time in one sitting, the potential pitfalls of the complex design and extra length of the 18650 tube makes its value questionable over simply throwing a 17670 battery into the existing tube. I mean an extra 17670 battery is only thirteen bucks and that would give you a combined runtime greater than an 18650 and without the need for the double jointed limited edition 18650 capsule style tube.
I'm using a 123x2 head on a 18650 body with good results since I prefer declining light output vs abrupt darkness.

no complaints on my 2cr123 head on 18650.
I thought it wiould be better than 2 AA, does this mean I need to buy a 2AA head next???
