Can't even come close in my reply but having had my Flex for a few days and testing it, I can say that it outperforms the Mag Light I was using by a longshot. Smaller, lighter, but much stronger feeling, and the programability puts it in a class by itself. 500 Lumens, with the beam pattern it has, is exceptionally bright and is good for quite a distance. So unless you need to spot boats or something at a distance over 50', you don't need anything else. and at the price point, it can't be beat.
