SC21 Pro, w Anduril 2 firmware update, thanks to gchart for the hardware and reflashing education.
.
Imo the SC21 can be a Total Package introductory gift light, with built in charging, tailmagnet, hatclip, deep carry clip, battery and charging cable. .
Thanks to the button indicator light, it can be located in the dark. Can be a good light to keep in the car, or as a:
Fridge magnet:

Pretty cool. Neat to see the light on with no body.
The Q8 while flashing, turned on the LEDs on the switch, with just the tiny85 clipped in.
Looks great; how did you reflash? I’ve never done it before….was it difficult?
thank you 
I found reflashing extremely difficult to learn, but some people find it easy, apparently it can even be done with an Android phone…
here are the instructions for an SP10 Pro https://www.reddit.com/r/flashlight/comments/u8t6x2/how_to_flash_firmware_on_the_sp10_pro_photos_at/
the SC21 Pro software process is the same, just uses different pogo pin hardware spacing
you can buy the hardware from gchart
be sure to specify that you need the full kit for SC21 Pro, (not SP10 Pro)
or,
I also offer reflashing and LED swaps… if you send me your light
or,
the SC21 Pro in this post is available for adoption, with choice of 519a or 219b LEDs I have in stock
PM me if interested in exploring options
I do not know. I use the stock mcpcb.
Maybe the Kaidomain mcpcb will fit… the 20mm looks like it has very similar cutouts to the one Sofirn uses. I do not know if the kaidomain is thicker.
Here is a photo of the SC21 Pro mcpcb, next to the Kaidomain 16mm and 20mm,
I have not measured the SC21 mcpcb, but the lens in this photo is 20mm:
maybe try a 20mm, and maybe also get a 16mm?
or learn to reflow onto the stock mcpcb?
