Fenix colour diffusers produce a smooth beam of coloured light that will not degrade night vision as white light would.
Hunters often use the red filter to avoid spooking game during pre-dawn hours as deer see poorly in the red colour spectrum. The blue filter is useful for picking up blood trails. The green filter isuseful for close range tactical applications such as map reading as it reduces the intensity of light output, while providing excellent clarity
