Klarus Red Filter XT11
This red filter has been specifically made for the Klarus XT11 tactical flashlight. It screws securely into the front of the torch when the strike bezel has been unscrewed and removed. So there's no way of the filter dropping off and being lost. A red filter can be used for hunting and spotting animals, since many animals cannot see well in the red spectrum. Red light also preserves our natural night vision and is effective at providing better visibility in fog and smoke.
