Built around an umbrella frame rather than the traditional softbox construction means the Westcott 135cm Round Halo Mono can be used without the need for an adapter ring it just utilises the 8mm umbrella bracket on the flash head. Setting up and taking down is quick and easy using the hook and loop tape opening at the rear of the box. A special opening allows access to the controls on the side of the light. Can be used with lights up to a maximum of 750w. The circular design allows a 140 degree wrap-round lighting with a circular catch light ideal for portraits. Also available in a 115cm version.
