Fenix is awkward to wear when hiking when compared to others such as Blk Diamond, Petzel etc etc. The Fenix run times are poor when compared to the others. Brightness appears to be the Fenix claim to fame and that is not what is needed by most hikers, campers, and kayakers. Try reading a map / chart with all those lumes. Plain and simple it is over kill times 500. They may be good as a flashlight however. In essence I'm not surprised at all. All the others are far more compact and much more easily adjustable when worn.
