90 mm head diameter is impressive - didn't expect it to be that big. The ThorFire S70S is 74 mm - I got one but not sure if I ever did any modding to it, nothing major like a custom driver for sure.

I think they made nice improvements overall - dims, the look, nice finning. I like the knurling on the tubes over the ring pattern the S70S had.
Could we please not quote that huge post with all those large pics, or at least remove the pictures from the quote? I like the pictures but not 50 times.
It does look like it suffers from your reflector pet peeves. Thick bezel and you can see the entire edge of the reflector from the front. If that 90 is measured from the outside of the head it’s much less ID.
I wonder how this light will perform with 2x Samsung 40T or 2x Molicell P42. The power of these cells should yield in way better lumen/lux numbers, shouldn’t it?
Ahhh, looks to me like they are including 18650 adapter sleeves, not for 21700's. For 21700's, the tubes and spring would have to be set up properly to go between short 26650/18650'a and 21700's and that gets tricky because you double the variance. It's probably a boost regulated so not sure if high performance cells well get you much, accept possibly longer regulated output times.
Not much info, so dunno for sure, but this my my guess.
It’s a FET driver but until someone measures how much the springs compress and how much room there is idk how you could for sure recommend something. If they tested with 18650 button tops in series any high drain 26650 button top (non protected) should fit. For 21700’s to really work without over compressing I’m betting a solder blobbed flat top works best since you probably wont have much room to spare for true button tops. They are hard to find in 21700 anyways (non protected)
Its using a Fet on direct drive on the highest output Sofirn got almost 7000 lumens with okay cells from the SP70. I would personally just use 26650s makes the most sense its made to use 26650s they should give best performance and run times.
