ARE YOU A PRO? Join for FREE!Olight Filter and Diffuser Fit Olight M20 Series LightsRed light is most often used to enhance, or more properly, not harm night 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:

"Filters are excellent for hunting(red/blue)which is why I was looking for them. Unfortunately the fit is quite imprecise on the Olight M20 Warrior they were purchased for. They readily fall off if pointed downward, when they should snugly hug the flashlight head, and for $10. 00 a piece they are very expensive and should be expected to function perfectly, so its disappointing to say the least when they obviously fall far short of that expectation. . . ."
"I love this filter! I am a night hiker, and use this several times a week. One warning, You really need to put a small wrist leash on it because it will fall off."
