The F06 is a blue filter for flashlights and WeaponLights with a 1.0" bezel diameter. Produces a smooth beam of blue light. Hunters use the blue filter to track wounded game at night because blood stands out more distinctly against foliage when viewed under blue light. The filter is also useful for close range, non-tactical applications - such as map reading -- as it reduces the intensity of light output.
Fits: All flashlights and WeaponLights with a 1.0" bezel
