The s8 is structurally identical to the s2 (I have both and only the aesthetics are different), and a lot of people have done some amazing things with the s2. I’m waiting for RMM to get his xp triple MCPCB’s back in stock so I can build a eye scorcher with the BLF17DD driver and triple xp-l in my s2. A couple of members here have dicouraged using the mt-g2 in that small (20mm) of a reflector because apparently it gives an ugly beam. What exactly did you have in mind?
I’ve built several triple XP-L S2’s S3+‘s and one triple Warsun Mini-5. They’d get pretty darn hot with a DD driver. I’ve been using standard Qlite’s, which measure around 3.05A at the tail. They don’t really ever get ’too hot to hold,’ but do get uncomfortable after about 3-4 minutes. I’ve taken to using 120 second turbo timers on them - makes for a very usable, very bright EDC light. They’ve definitely become the light I reach for the most for messing around the house.
