The Falcon Eyes SBQ-SB80120 Softbox is 80 x 120 cm in size and is easy to assemble. The SBQ-SB80120 is mounted on your studio flash unit with the included speed ring. The studio flash head sits deep in the softbox, which ensures minimal loss of light and provides an even spread of soft lighting. The SBQ series softboxes are equipped with heat resistant material and 2 valves. When using continuous lighting, it is essential that you open the valves to ensure the heat emitted from the studio flash unit is released.
