Vinh touched on it in video but for my purposes I am not sure this light is worth the price premium over a T6 or K70.
A lot depends on what you want really, if you want a large light with good heat dissipation and maybe 5 or 6000+lm for long periods, this would make a good choice. The F version is a beast! 20k (but say at 50% power) it is still a beast ,but will run well due to mass.
