This Dynalite 36 x 48" Softbox is designed for use with a strobe. With fabric not intended for the heat of a continuous light, this softbox comes standard with a white interior and a flush front face. The flush mounted front face provides a wider spread of light than a box with a recessed front. It's sewn in front face allows it to be set up in less than 30 seconds. Because there is no built in recessed front face, ganging the boxes together without a large black space between the boxes is possible with any number of these boxes.
