The Powertac Red Filter Cover is a flexible slip-on filter that fits over the bezel of a compatible flashlight to apply red light for the situation. It's compatible with the E5 Series, E9G4, E10 Series, E20, M5, M6, or any flashlight with a 25mm bezel. Red light is most often used to enhance, or more accurately, avoid harming night vision. It provides strong contrast and isn't easily visible over long distances, and works well with night vision scopes and goggles. Photographers use red light for night-time photography, as it provides contrast while preserving natural shadows. Red light also cuts through smoke better than white light, and, aside from red lines and marks on maps and charts, makes reading possible in low or no light.
