Smallest 18350 light?

Dec 2021 bump - have any new (small) 18350 lights been released?

Super small 16340-based lights like the Olight S-mini or new Klarus Mi1C are nice to have sometimes. But the (edit: no longer new) Aspire 1100mAh 18350 really makes me want an 18350 mini-light, to take advantage of the Aspire battery’s excellent capacity and high-drain capability.

Yes, I’m aware you can put an 18350 tube on an S2 or a D4, but those lights still aren’t designed around being the smallest light possible.

Options mentioned so far in this thread are in the table below.
The two smallest and largest dimensions in each category are highlighted. (the $400 boutique light is omitted).

Yeah, I’m still looking for one… not just small in terms of physical dimensions, but also weight.

Here’s a recent thread I started. You might find some suggestions there:

As far as I‘ve heard the new Jetbeam E20R should also fit 18350 cells, but I haven‘t checked that myself. Additionally it has a ring for reverse polarity protection on the driver, which means it might not be compatible with the flat top Aspire 18350.

Yesterday I got a Jetbeam RRT01 (similar but not equal to Niteye 10)! Takes 16340s and the Aspire 18350 fits perfectly on it :smiley:
No click switch; this control ring is vey good indeed, and the range of luminosity is awesome!

You can also find some suggestions here: Recommend me some 18350 lights

The other 18350 lights I have are the 3 (and another 1 on the way) Convoy S2+ with short tubes!
More:

- BLF A6

- Astrolux S1

- Astrolux S41 and S42

- Manker E14 and E14II

- Jaxman E2L

- ThruNite Neutron 2C V3

  • Nitecore MT10C (I will have one someday :person_facepalming: )

But, as you said, almost all are “shrinkble” lights! Not designed “on purpose” to be 18350s… :expressionless:

EDIT 1: Astrolux E01 ; MecArmy PT16 ; BTU Titanium

EDIT 2: SS15 (sold by Neal)

Ok, more budget solution this time.
I have some copper tubes bored to 19mm (six on the left). Dont know what to do with them, I wanted to giveaway them but cant afford it right now. I think scrap material in this box can be used to make custom “smallest” flashlight.

Copper tube triple XP-G2 18350 reverse clicky :slight_smile:

I was thinking, “maybe…” …until I saw the price, haha.

Got a link to a more detailed build thread?

It’s the copper core to the Cu & Alu mule I made, not really a descriptive build thread but slightly more information here

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.
