Are you talking about the thin ring on the outside of the spill? The way mine looks is that it has a spot in the center, then an area of spill, and outside the spill is another, slightly brighter ring that encircles the spill. If that’s what yours does too, then I would say it’s normal, as mine is that way too.
Same. The beam mostly looks ok. If I shine it on a wall one metre away, it will have a hotspot, a fair amount of spill, a dark circle a few inches thick, and a thin brighter circle similar to the outer spill brightness.
Others have commented about the ring they're seeing, which matches what I see in this image from the 5000K version I just got today. Is the outer ring the one you're referring to?
Mine does this as well. Think it is mentioned in a review somewhere. Has to do with the reflector and the part of the head that holds the lens. Normal.
I had to go white-ceiling hunting and crank it up to see it, but yeah, it’s kinda there way out in the periphery.
Does this light have pads for flashing firmware, which will make it easy to update with a pogo pin adapter?
Sadly no. I’m thinking about pulling out the driver once, attach some wires and a connector that fits through the hole for the switch. This would allow one to update the firmware by screwing off the switch bezel and pulling out the switch PCB.
With the Sofirn SC31 PRO flash-light off and the LEDs in the switch turned off too there is a parasitic current of 0,04 mA and regular peaks of 0.23 mA.

Is that normal?
Sounds normal to me. The microcontroller wakes up several times per second (and even in power save mode needs some current) and the ADC measurements for low voltage protection need more power (IIRC that’s done once per second).
Whoada. That's some nice equipment!
Haha! I was thinking the same.
Edit of #199: As many know, the A6 clip is great for clipping to a cap visor, too... I might be changing my clip preference!
Ok, this is a picture of all my favorite clips & EDCs with an SC31 in there somewhere. (L-R, Emisar, EagleTac, Convoy, A6 & Nitnumen)
Here is my clip solution , It is a silver clip I had in the parts bin , it is exactly the same as the standard black clip but in plain stainless steel , Not sure where it came from? Maybe off another light or Banggood??.
Cut it down and reformed the end for a reasonable shape ,I quite like it ,would prefer a deeper pocket fit I guess , What do you think?
That looks good! It looks like it may have been a Sofirn clip.
Is it possible to pull the driver down and attach a SOIC8 clip to update Anduril without removing the bezel for the reflector or desoldering?
I managed to remove the rubber switch cover with my fingers and then used circlip pliers to remove the switch bezel.
Notes for flashing the SP36:
Could the same be done with the SC31 Pro? :student:
I.e. Press down on the positive wire?

You know, the usual way is the other way around: First unscrew the bezel, then remove the switch cover. 
Yes, it should be possible. I will try it with a pogo pin adapter when I have time.
Does this light have a fet reduction in the firmware like the Emisar D4 with Nichia leds which has the fet limited to 80% if I recall it correctly?
Full fet for the SST40 seems a bit like overkill.
Does anyone know where else can I get the 18350 tube? Sofirn shops seem to be out of stock.I messaged their CS and they said maybe 2 weeks before they restock.
I could just buy an sp40 I guess, but that seems excessive. Even if it is a good deal of a light.
Full FET is OK if the resistance of the circuit is high enough.
It uses the firmware of the SP36 so it should have full FET. I just checked it with the scope and it is indeed fully enabled.
