Looking for my first headlamp and I am considering these two offerings, armytek wizard pro and the spark st6 500cw. The armytek is rated at 1010 lumens and the spark is 500 but I read the armytek is not ANSI lumens. Will the armytek be considerably brighter? I would like the brightest of the two but not sure I would like the armytek user interface as I like simple function. Any help would be appreciated!
