The Westcott Rapid Box Switch Strip Softbox 1×4 is built to match the fast-paced environment of professional photography. It allows you to fit one of the 13 inserts designed by Westcott in the basic attachment ring. You can use the silver interior to increase the light output or attach the diffuser fabric for soft fill light. Moreover, the diffuser is tested to reproduce accurate color in the final result. The durable softbox construction uses a metal framework and heat-resistant fabric. You can store or carry the softbox in the included case.
