The Olight Beam Diffuser converts the focused high-output beam of an Olight flashlight to a soft, diffused, wide-angle beam for close-up applications. Also popular for low light applications. Olight Diffusers use a high quality TPU body construction which offers flexibility, durability, chemical and abrasion resistance. The lens of the Olight DIffusers are made of ground glass. Lenses feature a top quality anti-reflective coating on BOTH SIDES for optimum light transmission. A lanyard loop offers convenience.
