Pros: Battery Life, Bulb Durability
Cons: None
Almost perfect
Have been looking for a better tactical light. Have owned several surefire products and while plenty bright enough, the batteries for these things don't last nearly long enough for my taste and even the cheapest batteries are outrageous. The Gerber TX3.0 takes regular AA that can be found dirt cheap at retail stores and last a whole lot longer. The only drawbacks are the length (kinda long for weapon mounting) and smaller outer diameter (again, for weapon mounting).
