Olight Red Filter - Fits the Olight M20 LED FlashlightsOlight Filter and Diffuser Fit Olight M20 Series LightsRed light is most often used to enhance, or more properly, not harm ni ght vision. Red light provides great contrast and is not visible to the human eye over long distances. It also works well with night vision scopes and goggles. Photographers use red colored light when doing night-time photography because it provides contrast while preserving the natural shadows developed by darkness. Red light cuts through smoke better than white light and, with the exception of red lines and marks on maps and charts, it makes reading in low, or no, light possible. Police and military units like the red LED for night operations because it will not interfere with night vision technology and cannot easily be picked up by other people. Features: Olight Filters and Diffusers outside use a high quality TPU body construction which offers flexibility, durability, chemical and abrasion resistance. The lense of the Olight filters are made of ground glass. Lenses feature a top quality Anti-Reflective coating on BOTH SIDES for optimum light transmission. Offer a lanyard loop for convenience. Compatible Models: Olight M20, M20SX Javelot, M20SX-L2 Warrior Show more
