The Maratac AAx2 LED Flashlight is a compact, powerful flashlight, powered by two AA batteries. The body is aluminum and is 7/8” wide. The tailcap is “Zombie” green, for no apparent reason. It activates by pressing it until it clicks. This means that there is no momentary-on. There are three brightness modes available: High – 620 lumens, Med – 110 lumens, and Low – 5 lumens. There is also a secondary set of modes when you loosen the head by ¼ turn. They are: Strobe, Fast Beacon(flash every 1 second), and Slow Strobe(flash every 3 seconds). To switch between modes, you simply “soft” tap(tap without fully depressing) the button, or quickly click it off, then back on again. There are raised fins around the activation button that shrouds the button from accidental activation. Personally, I believe it makes the button awkward to press. They get in the way, if you don’t position the light correctly in your hand. The crown of the light is crenulated, similar to a lot of other tactical lights, but it is not very pronounced, so I don’t think it would really do much damage if used defensively.
