Surefire F05 Red Filter for flashlights with 1.0" diameter bezel
The F05 Red Filter produces a smooth beam of red light that will not degrade night vision as white light would. Hunters use the red filter to avoid spooking game during predawn hours - deer see poorly in the red color spectrum. 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
