I'm curious about this flashlight. It won the 2007 Wired Magazine Editors pick for one of the best gadgets & gizmos on the planet.(from Brightguy.com) How bright is it compared to say Liteflux LF1 or maybe Fenix L1P? It stated the run time is 12.5hrs which is impressive. Anyone who has it, pls. share your experience. Thanks.
