Nitecore NFR23 Red Filter For Flashlight

The Nitecore filter transforms a standard Nitecore flashlight's centered high-output beam into a dim, wide angle, diffused flood beam. It is ideal for applications that are close-up and low-light, such as wide area lighting, short distance reading, camping, etc. Red light is used to retain the normal adjusted night vision of the eye; it will confuse the eyes with the least of all colors, enabling the eyes to remain adjusted for night conditions. Red light offers tremendous contrast and is not apparent over long distances to the human eye.

• Flexible filter frame is adaptable to a head diameter range of 60mm
