Surefire F36 Red Filter Fits 1.62" bezels, including 9AN

Red Filter for flashlights with 1.62" diameter bezel

The F36 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. The spring-loaded cover flips open with slight thumb pressure, and is held open by spring tension until manual pressure is applied to re-close the cover.

Features:

-Fits 1.62" bezels, including 9AN
-Spring loaded cover flips open quickly when white light is needed
-Provides secondary protection to flashlight lens window
