The Surefire F06-A 1.125-inch Diameter Blue Flashlight Filter is designed for flashlights and weapon lights, and produces a high definition beam of blue light. Hunters use blue light to track wounded game because the blood trail stands out more clearly when viewed under blue light. The filter is also useful for close range, non-tactical applications such as map reading because of the reduced light intensity.
