Smallest 18350 light?

If only they made a version of the S Mini sized for 18350. Le sigh.

A nice challenge for CRX !

:smiley:
Smallest 18350 light I’ve made was the copper & aluminium triple with FET driver & tail clicky.

Length – 60 mm
Width – 25 mm
Weight – 97 grams (with cell)
Max – 1400lm

update, I disagree with my former self

I tried an Eye10 and the detents are inconsistent and not spaced to my liking

it has given me a new appreciation for my RRT-01 smooth ramping dial… maybe I should try some hi cap IMR 18350… hmm

I think one of these protected button tops might be good… the flat top version does not work in the RRT-01
pic is a link to review

Can anyone confirm if these fit the RRT-01? (not too long?)

they are for sale here:

Probably too long. I made a custom flat top protected for my 01, very tight fit.
I had to grind the tail pin down and alter the RvPo ring to make it fit.
I could be wrong though, would be best if you could measure somehow with the cells you have and thin spacers?

darn
Protected Keepower, length: 39 mm
Protected Fenix 16340, length: 34 mm

maybe I need to go to the store and try the cell out in my RRT-01 before I buy it…

That would be good. Screw gently though, maybe with the o-ring off :wink:

CR123A is taller than 16340 too.
A 16340 with USB charging PCB is the same length as a CR123A.
Often 16340 lights are also meant to take CR123A, or vice versa.

Sorry to bring up this old thread, but I’m curious about if anyone here carries a 18350 flashlight in the keychain and how does it work out for you.

I’m interested in the new amutorch E3S which is probably the shortest 18350 triple out there, but now I’m not sure if to get it or save some money and convert my FW3A into the shorty which will cost me $13 with shipping. Ideally it would be the D4V2 or KR4 because of the fancy aux leds but i don’t how how bulky/heavy would that be on a keychain.

I don’t want to get a 16340 light because I am already carrying a Jetbeam mkii modded with a FET driver. Beam is pretty amazing but the short runtime has failed me on several occasions.

Any input is appreciated.

The Jetbeam is pretty small. Not sure you want a short D4V2 on your keychain.

Also, if you like the Jet-II beam, would you want to replace it for a floody light?

Edit: I cannot prove it, but would consider that the Jetbeam may have a longer runtime than the D4V2/18350 at the same brightness.

I would research to find the weight, with battery inside, for each of the 5 lights you mention, and then choose the lowest carry weight, in a light with the features you want.

No matter what light you choose, carry a spare battery, so runtime will not be an issue.

here is an example of a 16340 battery storage case that is quite small and lightweight

BTW, in case you prefer longer runtimes, you can get a light that takes 14500 and get some Vapcell or Shockli cells that are above 1000mAh. (more than the 800mAh that the best 16340 has). :+1:

Added a few options for small and light 18350 lights in the chart (in the first post).

Let me know if there are some other new lights I should add.

Let me know if you have any of the missing data points (indicated with question marks)

(or any of the data points for 18650 lights with 18350 tubes, I could not find weights with 18350 tubes often so I included weights with 18650 tube)

Given that the DQG Tiny flashlight is ~87mm long the usefulness of some of the longer 18350 lights is debatable.

Thrunite T1 is a pretty small 18350 light.

69.5 mm long and 26.5 mm at the head.

It’s very lightweight and has a built in charger.

I would love to see an 18350 light similar to the Fenix E16 or Olight S1 Mini. It doesn’t need any more output than either of those two. Just a slight size increase to allow the use of a more potent battery than a 16340.

Thanks, added.

Third sentence in the OP and third line in the chart…

2012 RRT-01
Length 81.3mm
Head 22.7mm
body 21.3mm
45 grams empty

Ah, I got as far as Astrolux but I do like my short S2
