As the name "Switch" hints, Westcott has introduced a line of softboxes designed for setup and rapid swapping out of different brands of strobes and speedlights in seconds. The Rapid Box Switch Strip Softbox is ideal for use as a sidelight, hairlight, for groups, or for selective lighting of your subject. Its long, narrow shape creates elegant, attractive highlights on reflective objects.. As indicated in the name, the softbox has a basic ring to hold it together, but instead of full speedrings, 13 "inserts" are separately available for a speedlight or 12 different brands of strobes. The quick release thumb-lock on the Rapid Box Switch ensures the security of your light. Besides the benefit of speed, the softbox is structurally sound with durable metal framework, heat-resistant fabric, and a reflective silver interior that maximizes your light source's output. The Rapid Box Switch Strip Softbox's diffusion material has also been thoroughly tested and found to be neutral, ensuring a true rendition of color. A carry case is included for storage and transport. So, if you need a well-made softbox designed for versatility - switch!
