This is a Bowens Softstrip Softbox. Its front diffuser measures 39.5 x 15.75" (100 x 40cm). The Bowens range of softboxes has been developed to offer photographers the very highest-quality light source at a very modest cost. Their silver interior and shallow construction offer a high degree of efficiency, while a translucent front diffuser ensures even light distribution.
To ensure easy transportation of your softbox a simple zip up carry case is included, as well as a speedring and an 'S' type adaptor for immediate mounting to your Bowens monolight.
Also included is a spare rod. Each softbox will accept all wafer adapters and can be used with most popular flash systems.
The adapter ring has a unique design that tilts out as the box is assembled. When the fourth wand is inserted into the adapter ring, the whole adapter swings into the assembly and locks into place -- no more struggling with a difficult fourth wand.
