Worlds smallest weapon light with 600 lumens. Also Bluetooth smart enabled for unlimited configurability. — at SHOT Show.

Ok.  This is interesting.  Forget using it as a weapons light.  I'm thinking more like a very powerful, probably durable keychain light.  600 lumens that's small enough for me to carry on my keys?  FourSevens is missing the forest for the trees....they need new marketing/gun guys.
