Smallest 18350 light?

The MecArmy PT18 Triple (V.3 only) like Illum. Supply sells can use non-protected 18350 cells.
Measuring 2.64 inches, it is well under 80 grams with the Aspire 1100 mah.
It has a built-in charger, if there is no other easy alternative.

PT18 uses an 18650 cell.

Maybe you meant PT16?

Illumination Supply has V.3
You can see 18350 included in the specs.

It is PT16 that accepts an 18350 cell, not PT18.

All the first (V.1) PTs had the horrible CooYoo/Blackwater SR71 UI.
Illum. helped them change to V2, still missing a Yobai mode.
V.3 is PT16 only, refering to the longer, wider tube.
I have one, believe me the combo is great, even better after an emitter swap.

The PT16 takes 1 18350 or 16340
The PT18 takes 2 x 18350 or 1 18650

All small PTs (10,14,16,18) will accept each other’s heads, they all go to 8.4 volts, and seem to use the same driver, along with the CooYoo and Blackwater SR71, also made by the parent company Altun.

OK, that’s better, but the OP is looking for the smallest 18350 light, so it’s unlikely that he’s interested in something like PT18 that requires multiple 18350 cells.

This is what you wrote earlier:

And that’s not correct. What you’ve described here is PT16, not PT18.

That’s all I was saying. :slight_smile:

Carry on…

BTW, the PT16 is really nice, actually, apart from the price. I just wish it had a clip. :slight_smile:

A clip….?
Interesting you should mention….
finally found one.

The Nitecore MH10 works well, $5.95 at the Nitecore store.

  • it helps to lift the tail of the clip when turning the tailcap,
    be care if trying to bend the clip to reform it, the metal may be too brittle to stand much force without heating first, and too much heat could cause loss of spring tension.
    It works on a cap brim, but will not deep throat……

an added benefit of the clip …
It makes it a LOT easier to find the switch

Thanks. This does not look very secure. :slight_smile:

It is almost too tight.
The spring tension makes it tilt a bit in the photo.

I’m thinking that the reason for the lack of truly “small” 18350 lights is:

If a manufacturer wants to build a small light that has minimum size and weight as a design goal, then they are incredibly likely to use the smaller and more common CR123/16340 battery format. The 18350 battery being close to the same size but slightly bigger, gets ignored. :frowning:

Just stumbled across Nitecore EC11 and added it to the list.

Nice find.

The clip looks reversible, although it would stick out if placed the opposite way.

Surprised it only lasts 45 min on 300 lm mode. Hopefully it would last longer when using the Aspire cell.

You can also add the Sunwayman C13R and the Sunwayman T16R!
Not my favourites in terms of functioning, but the both take 18350s!

EDIT : Another one Jetbeam/Niteye EC-R16 :wink:

Can you personally confirm the Sunwayman T16R takes 18350? I cannot find any documentation that says so, everything I see says 1x16340/CR123. If so, it is pretty small. Unfortunately 380Lm is not real competitive with most others in the class.

According to this post from Sunwayman, it does support 18350:

I’ve seen it here :wink:

I don’t have any 18350 flashlights myself, but just curious if 16340 and 18350 cells are similar or perhaps identical? I can’t help but noticed there are several posts indicating some flashlights will take 16340 or 18350 cells?

Close but not the same, 16mm vs 18mm, 340mm vs 350mm. Most 16340 will not take a 18350 but some will.

Some 16340s are longer than the 18350, though! I received a Wuben 16340, protected, that is longer than the Aspire 18350 unprotected.
It is not larger,though!
