I feel the same about 21700 cells.

Not many choices so far, though it's probably the cell of the future.

There are other types of batteries, not as famous as the ones that have been talked above, that may deserve an attention, namely 18500 and 16650.

For the first, it shorter than 18650, has less capacity than those, but has more capacity than a 18350, being slightly bigger.
Emisar D4, Jaxman, and few more lights use it (stock, not modded).

For the second type, I only knew it some time ago when I started messing with my On The Road i3 and M1. Together I can make them use a 16650 battery.
Recently, I also saw that 4Sevens (by Prometheus Lights, aka Jason Hui) will also launch a 16650 flashlight:
https://darksucks.com/collections/foursevens/products/quark-click-qk2l-x...

Not too large, longer than a AA light, with capacity around 2200mAh, being this more than 14500/16340/18350.
Although these are different types of batteries, they can be considered for EDC use for sure!!

For me, the most compact 18650 lights are very hard to argue with. They compete with the more typically-sized 14500/18350 lights, and are easily small enough for me to carry daily. I can tolerate a maximum size of a Convoy S2+, though lately I've favored my smaller lights much more heavily.

If we're going to talk about the smallest examples of each battery-type light, I actually rather like the 16340. It is thinner than 18350 and shorter than 14500, so super pocketable. In fact my D25C Ti is not as small as a 16340 light could be made, but because it's 16340 it is so easy to carry. I compare it to my AA/14500 lights (of which I admittedly have very few) and I don't want to switch. I also compare many 14500 lights to my ZL SC62 and then take the Zebralight. It does compactness just that little bit better than the D4/FW3A. 

So, the steps for a compact light:

  • Very short springs, don't support much extra battery length/width
  • Remove tail switch if possible
  • Triple/Quad TIR optics are usually going to be shorter than a reflector, but may be wider
  • Leave no empty space
  • Hard mode: Driver on the MCPCB (here's looking at Zebralight)

Olight s1r was my edc for about a year, and I still think the form factor is about perfect. But the battery began to be less than perfect on turbo, and the D4 came out. Now its the D4 with the 18350 tube, but if I could get a nice emitter, Anduril, a vapcell 16340 in my s1r, then I would be back to that for sure. I realize the emitter and vapcell are easy, but not so for Anduril.

Unno, I carried a Zanflare F1 and Nitefox UT20 and didn’t mind, and my current Nitecore MH20 seems much smaller in comparison. A bit weighty, but still disappears in my pocket.

In fact, a smaller light would have to have a *really*-deep-carry clip for me to use, and if not, it’d just get lost in my pocket and I’d probably have to empty the contents of my pocket to get to it. Not quite convenient.

I Bought a coupla 18350 cells for a torch earlier this yr.
They sit in drawer. Torch in cupboard.
The 14500’s and 18650 cover a90% of all I’ll ever need.

It was only bought as a novelty as it took several sizes of battery.

My Copper Olight I3T . Jetbeam Jet 1 Pro.
cover everything in that size.
with the 18650’s everything above to My L2/L6, 26650 size.
(My fav, holding, gripping, body size.)

I’d probably choose 14500 if it had more capacity and was easier to make good drivers for. That’s not much space though, and a lot of 14500 lights end up barely any smaller than a compact 18650 light.

I really like the Olight S-Mini, except for some of the overall Olight-ness of it, like only cool white except on the titanium version. The 16340 battery runs out of power fairly quickly and there’s no battery check or LVP. And the newer models aren’t as nice.

So I think I’ve gotta go with 18350. … even though I haven’t found any 18350 lights which are actually the size I want. Would be cool if someone made an 18350 version of the S-Mini though, with a good neutral high-CRI emitter and a BLF driver.

I wonder if On The Road would be up for manufacturing one of those.

Not sure if that would be feasible for them. However, this Sofirn project could end up like that if there was some opening:

I mentioned that in my comment on the thread. That would be quite amazing to happen!

I would have chosen 18350, but I haven’t actually found a light I like. So 16340 it is. I like the 18350 battery better, but the 16340 light better.

As BrandonNeil said, an S1R with 18350 would be my fav. Currently my S1 Baton is my fav until my S1R II Winter edition finally shows up.

The most intelligent choice is 14500 for its compatibility in size with regular AA… of course, not all 14500 lights can run on lower voltages than 3.6 (1.2/1.5)

I like the 14500 form factor better. I voted 18350 because in general it has more capacity and more developed than 14500.

no

and using LiIon means no sublumen mode… for me thats a Fail!

http://www.eagtac.com/html/d25arcmkii/specs.html#safety

Use only EAGTAC protected li-ion battery with compatiable length and diameter.

more info

for me, AA is Eneloop territory
