Hi, I'm new here and new to "lights." I'm looking for a carry light that can be used in a lighting emergency or as blinding personal defense. These 2 lights caught my eye. The Luxeon puts out more lumens but is slightly heavier and longer than the Centurian. And the Luxeon is LED. Any opinions or experience as to which one I should go with? Or maybe alternative choices? And what is the least amount of lumens that will temporarily affect a person's eyesight, even after it's off? Thanks.
