The F05-A is a red filter for flashlights and WeaponLights with a 1.125" bezel diameter. 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 pre-dawn 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 1.125" bezel
