Olight Filter for M30 - Red

Red light is most often used to enhance, or more properly, preserve night vision. Red light provides great contrast and is invisible to the human eye over long distances. It also works well with night vision scopes and goggles. Photographers use red colored lights 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 to zero light possible. Olight fliters use a high quality TPU body construction which offers flexibility, durability, and chemical and abrasion resistance while the lenses are made of ground glass. The lenses also feature a top quality anti-reflective coating on both sides for optimum light transmission. A lanyard loop is built-in to the filter for easy transport and storage.
