Yup, this one as a weird head, but there is another version, without knurling (and that looks like a Thrunite flashlight) out there, at least in Nitefox website!
It’s the ES10 I guess.
This is a nice light, though, despite the UI. When MTN has 15mm drivers again I will get one to replace the stock driver (although I know it will get hot with a Li-Ion and FET driver :smiling_imp: ) !
