This is an outstanding item for almost ANYONE. Yes, designed for those tactical mindset folks but it's a fantastic value and I've never seen before such a light source that also had the 'infinitely' variable option of 500 lumens right on down to .5 lumens. Best new light feature since the LEDs.
This little gem even comes packaged like the manufacturers value their product. Awesome buy for and Scout, LEO, Service member, utility worker, shooter of home defense leader.
