Is there a 2 x 14500 light available?

[slate]

I have seen single 14500 lights but is there a light out there that can run 2 x 14500 besides something along the lines of a modified 6P style light?

You can try Quark's 123^2 head with a AA^2 body.
That's what I'm gonna do with the set of Ti Quarks i bought. It should work, in theory at least.

But other than that, can't really think of a mass produced 2xAA light that can take 2x14500.
3V and 8.4V is just too big of a difference to allow for flat regulation in both configuration.

Most 3x CR123A lights can take 2x 14500, but most users opt for 2x 17500 for the extra runtime.

+1

This is one of the easiest ways to do it, and the light would have great performance. +2 or 3, can't remember.

If you haven't already bought the 14500s, I would think that a single 17670 on the 2x123 head would provide more energy while being shorter? Correct me if I'm wrong..

That, I'd love to know about.

IMO, the most common li-ions are 14500, 16340 and 18650.
An addition of some "weird" number like 17670 could pose as some logistic issues..... but thats just me

Ideally, you would couple the 17670 cell (loaded in the 123x2 body) with the 4.2 volt head. The 17670 is just a larger (size and capacity) RCR123. It makes sense to mate this cell with the head that is suited for its voltage.

PS: I know NOTHING about batteries, I'm just getting into this aspect of the flashlight game.

That gives you a bit less runtime, and when the batteries die the protection circuit just cuts the light off. On the 123^2 head the light actually dims and does not trip the protection circuit as quickly.

Is there any advantage to 2x14500 vs 2x16340? The Quark 123^2 form factor seems a lot nicer to me than the AA^2 form factor. Plus with the 123^2 you have the option of using one 17670.

 

[berry580]

im not sure, but does 14500 have a higher capacity than 16340?

and yes, with the 123^2 you have the option of using one 17670.definitely a plus.

using a 17670 with a 123^2 head would mean a less regulated turbo mode due to its lower voltage.

So quarks have protection circuits? I never knew that

Before I bought my Quarks, I sent a request for info to 4sevens and got this reply from Mary:

Thanks for contacting us. The 17670 battery works well with the lower voltage Quark head. It is not practical to use in the Quark 123x2 because the voltage is not high enough.

Because of that, I ended up ordering a AA with a 123^2 tube. Unfortunately, the 123^2 tube wouldn't thread with the AA head and 4sevens asked me to send everything back. A week later, I'm still waiting to hear back from them.

Output is the same with longer runtime on 17670 vs 2x16340 on the 123^2 head or 1x17670 on 4.2 head. Check the runtime graphs...

And no, the CELL has the protection circuit that gives you sudden death in the 4.2v or 2x configs.

I don't know if it's the light or the battery but some combinations of Quark heads and bodies do suddenly go dark on turbo when using AW RCR123's in my experience. They won't come back on until you charge the batteries from what I've seen.

I've tried the QAA-2 body with the Q123-2 head and two 14500's, it works fine. Just don't get confused and put the QAA-2 head back on with the 14500's, it might set off the smoke detector.

and yes, with the 123^2 you have the option of using one 17670.definitely a plus.

Great combination, I have one here with me as I watch the typhoon winds howl in Hong Kong. If I need extended lighting, I have a few spare CR123's, although these are becoming increasingly restricted on airlines due to hazmat considerations.

So if you had some 14500 batteries and one or more 17670 batteries, it strikes me that if you ordered two Quarks: a 2xAA and a 2x123, you could just swap heads, run the higher voltage head with 2 AA and the lower voltage head with one 17670 battery. Granted, I don't have any quarks to try this with, but it seems that it would work.

Would this also then apply to Fenix lights, such as the combo of an L2D and a P3D?

I have a true sleeper 2x14500 ROP I'll sell ya. Looks like a kids plastic toy until you turn it on and BAM! oo: Well over 300-400 Lumens out of a thinner than 6P sized light... for about 20 seconds at a time until the plastic starts to soften and the cells .

Yes, indeed, as long as you power the high voltage head with Li-Ion cells. Alkaline or NiMH AA's obviously wouldn't have enough voltage.

i can use 2x14500s in my Fenix TA30, that light can run on 3xCR123s, 2x17500s as well.
