Sofirn is also an OEM/3PM, i.e. they are sometimes commissioned to producing flashlights for other brands. AFAIK, Utorch is a Gearbest brand whereas Astrolux is a Banggood brand. The Utorch C8F is a Sofirn C8F with only another name on it. The Thorfire "BLF" Q8 was also manufactured by Sofirn and sold by Thorfire.
The SP36 has USB-C charging but no powerbank function. It uses XP-L2 instead of XP-L HI to gain comparable output to Sofirn's Q8. Actual output tested by some BLF members is about 5.000 - 5.400 lumens. All cells work in parallel (3p) and button top batteries are crucial for operation. It works with NarsilM 1.2. Sofirn told me they might incorporate Andúril into the SP36 later on but nothing is confirmed so far.
Fin17, if you agree and if it's helpful to anyone interested into the SP36 you could add the NarsilM 1.2 manual into your OP. I have it available both in English and German. Please click ► here ◄.
