Yea I dont believe the run times either.I put 11,000 mha Titanium brand rechargables in it and it will run longer than I can,but dont know how long.It will throw about the same as the 4aa propoly with a much wider beam.The light coming from it is a nice tint of white,and the brightness seems constant for the life(at least 50%) of the batteries.It lights my barn up nicely at 50 yards,and the tops of tress at 70 yards.The lanyard that comes with it looks to be exactly like the ones from Fenix.The sheath it comes with seems cheap compared to the ones from Fenix and Streamlight propoly's,and its got a plastic lens and It's made in China.I took a chance when I bought this light,I couldnt find anything about it,if it was sold anywhere else I wouldnt of bought it,but I'm glad I did.
