Some very quick notes after unpacking;
- Anduril 1 on both apparently.
- Buttons feel very different between the 2; 1 has a nice click, the other is hard to press.
- Different settings between the 2. Did factory reset on both.
- Switch light works and can be controlled! Colour green.
- LEDs differ in brightness. 1 is noticeably dimmer than the other.
- Bezels glued.
- No manual included (as opposed to the SP10 pro)
- 1 is a bit damaged. Not round, see driver photo.

1) Can confirm that mine came with Anduril 1.
2) Mine came with the stiff button type (no click).
3) I don’t have a second one to compare.
4) Mine came with the Anduril 2 manual (lol).
5) No visible damage to my light.

What the heck is that flashing pad layout again?!

congratulations on receiving your lights.

sorry to hear they are not Anduril 2.

here are some of the things that some A2 lights have, that A1 does not:
1. Automatic lockout
2. Hybrid memory
3. Simple UI instead of Muggle mode
4. SOS

Yeah,my thoughts almost exactly… in my mind it ‘heck’ was replaced with a less decent word Wink

Pin mappings? Really want to flash Anduril 2 on at least 1, but not sure how to hook this one up. What MCU is inside? In any case another custom pogo pin setup Facepalm Really wish they’d settle on some sort of standard, even if it’s just Sofirn only.

Anyone know a way to contact Barry? Could send a PM, but prefer not to do that for orders that have nothing to do with BLF. Sofirnlight’s email seems to be out of service and I don’t have FB messenger.

Edit:
Maybe mail works these days. It seems they’ve switched from service@mail.sofirnlight.com to sofirnlight@gmail.com

Plot twist: Designer saw that every flashlight has shiny pads at the driver side, each with a number or letter. So he added some as well. They aren’t connected to anything. But now the driver looks like a proper driver.

Or maybe they started from pin one and there was only enough room for six pads, leaving the important one unconnected.

Very crappy 1st attempt at using ceilingbounce that I had to cut short. Started on high, battery around 3,85V. But it’s better than nothing and it sure doesn’t look like the nice flat curve of the non-pro version. Make of it what you will.

PS: both were relatively easy to open.
PPS: it appears the switch LED does not indicate voltage. After the above runtime test the battery was at 3V, but the switch is still green. Not red, not blinking. But less bright it seems. It does turn red when charging.

Have you calibrated the temperature sensor? What you see is the thermal regulation.

Anduril can control only the green LED.

Nope, I thought that was only needed for Anduril 2… hold my beer

Edit:
I let it cool down for a while, but even then it seems to be set 7 degrees higher than the real temperature. Leaving it over night to stabilise.

I was looking more at the high runtime, since turbo creates a massive peak and messes with the general overview imho.

Anyway re-did it, temperature calibrated. But I need a better way to deal with the output that ceilingbounce creates. Once the pro goes lower brightness, the numbers get so small compared to turbo that they visually disappear. Not very practical. Or I’m missing something. In any case at lower levels it’s pretty flatlined.

Applying my very limited openoffice skills I managed to split it at roughly at 60 minutes.

Depends on the MCU. The SP10 Pro doesn’t need calibration since the sensor in the MCU already is, if I’m not mistaken.

Ah, so this is where folks are discussing the SC21 Pro. I had a similar experience: Two SC21 Pro’s arrived with slightly different out-of-the-box configs (one with stepped ramping, and one with smooth). They are both 5000K, but one is consistently 200-300K lower than the other (different bins, I guess). Both came with Anduril 2 manuals, but they are definitely running Anduril 1. Both bezels glued, but a couple of strap wrenches made quick work of that.

So has anyone torn down an SC21 yet? How do you get the driver out, and what MCU does it use?

Might be better to have a separate thread for the pro version. Maybe an admin can split this topic into 2 at few posts back and create a new pro specific thread?

Interesting that you’re reporting the same settings and emitter difference. I can imagine they switch to a new reel/bin once, but twice in a very short period of time… unlikely. Mine seem to have a slightly different tint, but haven’t done any proper comparisons due to having too much to do already. In any case it’s curious.

Btw, a word of caution. These suffer from the same charge problem as the HS10. After the runtime test I put it on the charger and saw it charges at just under 950mA. Sofirn rates their batteries at 750mA max. May or may not be an actual issue, but it is ~25% over their own specified limit.

Edit:
Current measurement: just under 3,5A on turbo with included Sofirn battery @4,18V

Just an observation, the SC10 Pro button indicator light changes brightness, when the light is ON above 75 Lumens:

I donk know if there is a meaning to that change in button output.

One thing Im really happy about, is there are NO double blinks anywhere in the ramp on the SC21 Pro..

about charging, it works great!
The charging rate tapers down as voltage rises:

and the green charged indicator lights up reliably, above 4.1v, and charging stops:

pocket clip works great too!
I put some shrink tubing on the ears, and it goes on without damage, and holds nice and tight.. the clip is a nice deep carry configuration.. I like it!

Awesome idea with the shrink tubing. I’ll have to try that. Was 0.8A the highest charge voltage that you observed?

I just want a confirmation on the switch button being able to turn on low and high and off for the Anduril versions.

Also the Anduril version is Anduril 1?

Both of mine are confirmed to be running Anduril 1, and I am able to cycle the button LED between low, high, off, and blinking.

Awesome and thank you.

The illuminated button is a feature I really like on flashlights.

Has anyone contacted sofirn to see if sofirn will reflash existing lights to anduril 2?

Description specifically says anduril 2. Maybe no compatible firmware hence anduril 1? Was planning on ordering with sp10 pro when sp10 pro in stock but now I’m hesitant

I have not contacted Sofirn about it. I was actually hoping that someone here would figure out how to flash it, and then I would do the same. Smile

For the benefit of others I would emailed sofirn. It’s false advertising. Of course I doubt it’s malicious, knowing sofirn it’s probably a case of copy-pasting and not proofreading.

At the very least it would encourage them to update their stock descriptions.

Sofirn is opening themselves up easily for disputes if buyers wish to do so. I have not purchased so I cannot email. Otherwise if I owned one I would.

I don’t want to open any dispute asking for a replacement/refund because I don’t want them to lose the money. An exchange is fine but I don’t know how they are going to work it out.

Hank solved the Muggle-Mode bug issue by creating a flashing tool and selling it to existing customers of the D4V2 at self-cost. I’d welcome that also for solving the SP10 Pro firmware bug (though I personally don’t mind and have not openend a case with Sofirn, but am rather grateful they produced it).

Looks like Sofirn removed Anduril from the item description.

Changed to anduril 1 on their website now

And to be fair:

While Anduril 2 is better, Anduril 1 is still quite good. Finding either Anduril 1 or 2 on a low-cost budget light is impressive… and probably a far better UI than what most budget lights come with.

Cracked open my SC21 Pro to do an emitter swap and removed the driver. It’s also glued, but a short time with a heat gun made short work of it.

It’s running what looks like an ATTiny1616, and comparing the flashing pads and where the pinouts from the controller connects, this is what the pinout looks like as far as I can tell:

2 – GND
6 – VCC
5 – PA3/EXTCLK
4 – PA2
1 – PA0/RST/UPDI
3 – PA1

Thanks for sharing that! Pin 1 says UPDI, so probably the same way of flashing as the SP10 Pro.

Now that’s interesting! I had heard that they were planning on using the attiny1616 for the SC21 Pro, but then Barry seemed to go quiet so I never ended up hearing for sure. Did you / could you grab pics of the driver? I can’t believe they didn’t use the same flashing pad layout that I had provided. At least there are pads, I suppose. I can always rig something up if I need to for flashing.
