Red Filter for flashlights with 1.25" diameter bezel
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 of light output. Applying thumb pressure to
the locking tab releases the cover; a spring mechanism keeps the
open cover out of the way by holding it flat against the flashlight.
A cam-locking lever keeps the entire unit securely attached to the
flashlight.
