This light was recommended to me by more experienced competitors once I started planning for a night match. A lot of light for the price, tailcap is solid, very solid throw. Add the flip-away diffuser and you've got a great hotspot/fill for close and are a flip away from "I need that thing 300 yards out to be bright right now".
