Surefire F06 Blue Filter Fits E1 and E2 Series Flashlights

The F06 Blue Filter 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.
