Sofirn SC21 mini

Cool! Finally, I can make good use of my Shockli 16340. Will order one. :slight_smile:

Is this any good or is it an afterthought?

Looks good but I think the 16340 is SO limited compared to an 18350.

Kinda not much different than a SP31-pro with short 18350 battery & tube except less lumens & runtime. Nice light though.

1000 lumens in that will last a couple seconds, but with ramping looks good especially using the LH351D. $25 is pretty steep for that though when the FWAA is only $20 more…

Yeah but the FWAA still has FW problems. There are decent 16340 cells out here now days. No reason not to buy this light if it fits the form factor you are looking for. I have a boat load of Vapcell 16340’s, now Sofrin has givin me something to use them on.

it should manage atleast 30 sec or so… similar olights manage that so this one should too.

Is there a deal on it right now ?

The Sofirn site does not want to show me shipping fees for Canada.

First CR123 sized light I’m interested in a long time…

SC31PRO WITH 18350 TUBE COSTS LESS.

Your shift key is stuck.

Either that or he’s Samu L Jackson. :smiling_imp:

Yes but it’s not as small. I would really like to see a comparison picture with both lights.

I have the prototype here. The light was originally planned to be sold under a different brand.

From left to right: Sofirn SC21 prototype, Wurkkos FC11 w/ 18350 tube, Sofirn SC31 Pro w/ 18650 tube

I have recommended Sofirn to enlarge the inner tube diameter to fit 18350 batteries. It seems they decided otherwise. The input current of 1A via USB-C (equals to about 1.5C) is a bit much for this small battery and may reduce its life span.

I bought 3 SP31’s with extra short tubes, magnetic tailcaps & diffusers. Very good little lights for the money. I grab the short 18350 over my Olight baton-III as it’s more powerful and sustains higher outputs for much longer. The little 16340 Olight on turbo chews most of its power in under a minute. I like the Olight as it has that Zippo style unique charging case and it’s a good light but if going out for a walk for an hour it’s just not the right choice. I’ll probably buy this new Sofirn just based on their value for MSRP but I bet the short tube SP-31p does everything brighter longer for a small increase in size. Olight 16340=550mAh vs Vapecel T14 18350=1400mAh….so yeah a fair bit of difference for such similar sized cells.

This looks good. I’d like to get one but I’ll wait for more information about the UI. So far I haven’t seen a good ramping UI besides Narsil and Anduril. My only experience with a Sofirn ramping UI is the C8F which I hate.

The C8F UI has (had?) a severe bug (will stuck in moon mode). With that one corrected, it’s a nice UI (SP33V3 seems ok). The only thing I would add is the ability to ramp up- and downward randomly, like Crescendo does and unlike Andúril which annoyingly forces you to wait until you can ramp up after already ramping up. Annoying.

Any kind of regulation in this light? Is there a runtime diagram already?

I’m gonna hafta play with my C8F, as I don’t recall anything evil in the UI.

Only thing I had issue with was turning it really off I’d turn it off via the sideswitch, then unclick the tailswitch, then TCLO the beastie. (Yeah, overkill.) Gotta remember to do all 3 in reverse to just turn it on again. :laughing:

Lux-Perpetua,

Thank you so much for posting this, I appreciate. That.s exactely what I needed to see. :+1:

Since I'm a total noob... Would you mind breaking this down a little further for me, please? I've inherited -- long story -- a Torchy and an OlightS1R, and would like something similar. I don't mind going a little larger to get a longer run time. Thanks for any help!

the advantage of 16340 is that it is lower weight and smaller size

16340, 18350, 18650:

here is the 18350 version:
(pic is a link)

the advantage of 18350 is that it has more capacity
the disadvantage is the battery, and the light it fits into, is larger, and heavier…

your S1R uses a 550mAh Battery, size 16340 (16mm diameter, 34.0mm long),
that weighs about 18 grams

an 18350 Battery (18mm diameter, 35.0mm long),
that weighs about 25 grams,
is available in 1200mAh capacity,
double the capacity of the Olight battery.

however, if we use less lumens, we get more runtime
it can be misleading to focus on maximum lumen runtimes, if in reality we seldom use maximum…
so, be happy with your 16340 light and dont worry about capacity and runtime, instead, avoid using maximum… :slight_smile:

16340 is 2mm smaller in diameter than 18350

Example Sofirn SC21
a light whose head was designed for a 16340 body tube, will not accept an 18350 body tube, because the diameter is 2mm larger… the parts wont screw together.

Example Sofirn SC31
an 18650 flashlight can easily use an 18350 body tube, because they are the same diameter.
