The Pro Plus Strip Softbox is designed for use with a strobe. With fabric not intended for the heat of a continuous light, the Plus Strip comes standard with a silver interior and a recessed, removable front face, which provides more control of light than a box with a flush front.
The "plus" designation means the front face may be removed. A 1/2 or 1/4 strength fabric could be used instead, for slightly more light transmission and less of a softening effect.
The large size provides photographers with the ultimate solution for lighting tall people evenly for full body fashion or portrait applications.
Required Speed (mounting) Rings are available separately for many manufacturers' strobes.
