[review] Sofirn SC21, 16340 mini-light with usb-C recharging!

Is there lvp in yours?

It’s not bad at all, I think. Compared to my Jet-II twisty, it doesn’t have any sideswitch nor charging port, so is certainly compact, and once you twist it on, it’s pretty easy to hold.

Add the charging and sideswitch, and there ain’t much room to put that without necessarily making the light bigger. It’s still pretty easy to hold precisely because of the extra length, so I got no complaints.

If I remember, I’ll try to get a side-by-side pic of the ’21 with a shorty SC31pro.

Hmm, doesn’t jingle any bells. Was it from a reeeeally long time ago?

Ach… ya gonna make me run it down to vapors?

I had an interesting experience with turbo stepdown. First time I tried it, it stepped down rather abruptly, but yesterday when I got curious to see if it was timed or thermal, it kept cooking and cooking ’til it almost got too hot to hold.

Will try both, I guess.

It’s just someone said it doesn’t or at least theirs doesn’t work. Hopefully it doesn’t go that low.

At 3.8V now… will let it sit quietly on high, see if it does anything.

Had it on, dimmed, would abruptly step down from H to M, then M to L. Switch light was off the entire time unless I’d bap the switch for something.

About 3V and below, the switch would blink on/off constantly. Good so far.

Below 2.X, the blinkenlicht would stop, and the main LED would just glow dimly, about L if not moonlight.

Gave up, pulled the cell at 2.79V (about as low as I’d want to go; “rested” a few sec between starting to unscrew the light and measuring the voltage) and am recharging it now.

So maybe it’s a glitch that when the blinkies would stop, the light should turn off, but doesn’t, as low-voltage warnings seem to work, but not pull the trigger to actually shut off entirely. I didn’t want to chance killing an already weak cell.

Me, I wouldn’t let it get that low to begin with, but I can see if someone would leave it on unattended (or turn it on accidentally), where that might be a big problem.

Thanks for the test. I wouldn’t intentionally go that low either but it’s nice to know if lvp works just in case. I think I’m sticking with the shorty SC31 pro. I have a Wowtac W1 and don’t use it much. Practically the same light.

Nice review. Except for battery check, Sofirn really nailed the UI in this light and I love the fact it takes standard optics.

Oh, forgot to mention, try

“The code is coming! 20%off code: PP3x9UNN (it’s valid till August 30st.)”

CHANGE ’×’ to ’x’!!!

Heh-heh… “pee-pee”.

Nice!
I have an Olight S1 Ti Baton that I really like for it’s amazingly short height, but the relatively low mAh of 16340 cells always annoyed me. Many are around 600mAh. The best I’ve got is 750mAh. So it’s nice to see Sofirn managed to pack 900mAh into it. That’s equivalent to many 18350 cells.
Price is rather attractive. At $29.99 out of the gate, you can imagine later discounts could bring it down to something like $22.

how easy is it to get to blinkies inadvertently?

can it also use cr123a also - and run those down to nothing (and know it is not a 16340)?

i can;t believe anyone actually likes ‘hold to change light level’ UI though

900 mah . Hopefully but I doubt it. Sure would make these small lights nicer.

That would be nice, despite I think it will not be much different from this, comparing the Wurkos FC11, posted by Lux-Perpetua:

Hum, some years yes, 3 or 4, eventually, but it was a more or less generic model, so it is likely that it was not very appealing here. Some other brands like “CrazyFire” and other have that kind of model.

Wellp, everyone and his grandmother wants click on/off, so what else is there?

Would you rather have click to change level and hold for off? That’s the alternative, and it’s generally considered stupid. I’m looking at you Lumintop.

That’s one thing that pushed me into trying out 18350 alternatives. You can get some that are near the length of many 16340 flashlights. But a 16340 cell offering 900 mAh really makes that cell competitive again, for those of us that find 700 mAh a bit anemic.

It’s a whole “different language,” if you’re gonna click to step up in brightness, then press+hold for off becomes the natural thing to do. And that might feel “logical” for a light where you press+hold for on as well, starting on moonlight.

I prefer press+hold to ramp up, then double-press+hold to ramp down. Single click—off, single click—on. But I like the press-hold for on/off for EDC keychain lights, which easily thwarts accidental activation. Some use double-click on, like RovyVon, and it’s a bit annoying.

Narrator: It isn’t :smiley:

I did a bit of an LVP test. It got to where the LED was very dim, measured 2.45v, came back to 2.55V after 10 odd minutes. Popped it in a Mixboxer C8 which measured 707mAh after 2h27m charging.

Oh well, looked good on paper .
