I'm surprised they still make/sell this model without even updating it as it's quite old - as evident by the XM-L2 LEDs in the unit and only producing 3450 lumens for its size.
The model was pretty popular for on-screen uses thanks to its unconventional design, appearing in shows like Westworld and movies like The Hunger Games and The Mummy(2017).
I'd be interested if Klarus stuck a USB-C port on it and used XHP-35 HI's.
