Velux Fresnel Diffuser
The Velux Fresnel Diffuser is an option to replace the standard frosted diffuser which is part of the Sun Tunnel kit. The Fresnel diffuser has a distinctive look offering peaks at a blue sky above and the occasional rainbow inside. The fresnel diffuser is available in round diameters of 10", 14", and 22". A 24" by 24" square size is also available. The 10" and 14" diffusers come with a pre-assembled and paintable ceiling trim ring. The commercial-size diffusers (22" round and 24" square) do not come with a trim ring and are designed to fit with the commercial ceiling components.
