Sofirn SC21 mini

anyone have this in the 2700k tint ? seems like a good deal getting below 3000k tint in this kind of light. Shame about the high drain issues that shouldnt happen.

I had the same problem. It’s kept me from using the light since I can’t trust that it won’t just kill batteries for fun.

Just tested my SC21 using a benchtop power supply set to 4.20VDC and a Tektronix TX3 DMM wired inline.
Light off= 41uA.
Light in lockout= 60uA.
I watched it for a while and the current stayed steady, no pulses or change in current.
I’m topping up the battery now and I will leave it in lock out for a week to see what happens.

I got one a little while ago and I really like it. It’s quite small and fits perfectly into a small gear pouch like it was made for it. Yeah, the battery life isn’t quite the same compared to a 18350, but it’s easy to charge with one of the zillion charging cables I’ve got laying around these days. I just think it hits above its weight class for a very easy to carry light with quality construction.

Anyone tried to open the SC21 up? mine just stopped working and its not from the battery side. The led and copper plate seems fine. Must be driver/ charging are. Does not want to be unscrewed. starting to wonder if they have glued it in place…

I opened one a while back. There was a huge amount of red loctite. I had to sandwich it between two pieces of wood at the flat part of the cooling fins, and then use locking pliers with leather on the bezel.

The top is opened, but i have problems with taking out the driver, the PCB that meets the batterie’s positive end. I believe after some research that they glue them in place… Pure ultra violence in small scale will commence!

That sounds familiar, too.

Yours has low idle/quiescent current… I wonder if yours may be from a different batch?
(my SC21 were ordered around last week of September from Sofirn/AliExpress, and they arrived around last week of October).

I have the SC21 with 5000k, 4000k, 2700k and all of them have high parasitic drain when in Lock-out mode.

how is the 2700k tint ? dta ?

My favourite, but i’m kind of a sucker for the old incadescent bulb-light kind of thing.

Right: Sofirn SC21 (LH351D 4000k)

(at the end part of the video, the 5000k is also shown)

(pardon my old digicam doesn't seem to focus warm color temperature and relatively low brightness that well, so there are parts of the video that gets defocused)

2) (just very recently, someone was able to order for me from Amazon the Lee green filter, which I have been wanting to try for some years now, this is my first attempt to try it on the flashlight)

Left: Sofirn SC21 (LH351D 5000k, with minus 1/4 green Lee filter)

Right: Sofirn SC21 (LH351D 5000k, stock)

(comment: there is a noticeable slight drop in brightness when using the minus 1/4 green Lee filter, probably something like 10% or so drop in brightness

BUT, the beam now looks much nicer)

great videos thanks.

2 week electronic lockout battery drain test-
Nov 14 battery voltage (freshy charged) 4.145V
Nov 28 battery voltage 4.097V.
My light is not draining the battery when in electronic lockout.

I was able to remove the magnet in my SC21.

  • I removed the spring by compressing the triangle so I could lift it out.
  • The magnet was lightly glued in place, but there was a small gap around the edges of its cavity. I inserted a small screwdriver into this gap and then lightly hammered the back of the screwdriver with the side of a pliers.
  • This worked quite well. The hammering broke the glue and shifted the magnet sideways in the cavity. The magnet fell right out after that.

What is that SC21 Pro mini? Very strange looking listing in AE store.

Pro = Anduril 2.0

good find :+1:

Yes I know that but description is wrong led emitter choices are black, green and blue and body color is 5000k :smiley: I thinking to buy SC10 Pro but if that’s SC21 have the same electronics I maybe will buy SC21 Pro, also my current EDC is SC21.

I am asking myself the same questions

the advantage of SP10 Pro is that it is the only Anduril light that works with AA batteries, and it is thinner than SC21 Pro

the advantage of the SC21 Pro is that it is the smallest Anduril light plus has built in Charging and battery indicator light on the switch, and it is shorter than SP10 Pro.

Im leaning towards SC21 Pro, because of charging convenience as a gift light to a muggle (thats my excuse anyway). My prepurchase consideration is that Im not sure yet if it has the same low firefly modes as the SP10 Pro, which are the lowest Ive ever seen in an Anduril light.

In SC21Pro we will lose the big advantage of SC21 in that smaller size. It’s use buck driver which is important for that small battery to have longer running times. Also I think the new version of SC21 will be just another simple FET based driver without stabilization.
