Surefire FM35 Flip Up Red Filter for SureFire Flashlights with 1.25" Diameter Bezels
This filter fits the G2, G2Z, 6P, C2, and Z2. The FM35 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 oflight output.
