I absolutely love the idea of mega-bright lights. Maybe it’s a guy thing? 
That said, what I know, and what stops me from buying ones like this is; they burn hot and fast (I only get like 20-30 minutes from my 2k lumen flashlight), they’re rarely the advertised brightness, they’re rarely dual-battery (Li-ion or disposable), and the exorbitant cost.
Typically, these things are all made in China, just like everything else. I could find my way to $40-60 for a torch like this. But $150? Whew…I don’t need it that badly.
Message to the supplier; get past the novelty greed, lower your prices, and you’ll make a lot more sales.
Hence channels like the Torque Test Channel which has put a number of lights to the test. I don’t recall them testing this one before, however.
