Gary Fong introduces the Lightsphere Collapsible, the new evolution of the famed Lightsphere series of diffusers! The Lightsphere Collapsible is made from soft vinyl making this Lightsphere flexible yet durable. The Lightsphere Collapsible boasts the first mounting system of its kind. It utilizes patent pending sizing ribs to provide an equally tight fit to several sizes of flashes without the need for straps or bands and collapses down to a 1 1/2 inch thick ring allowing for easy storage. The Inverted Dome, which works with all exisiting accessories, is included with the purchase. The light output is equivalent to a half cloud.
