• The Ultra Softbox III is designed for use with a strobe & not intended for the heat of a continuous light. Ultra Softbox III comes standard with a white interior and is quick to set up and break down. Softboxes are ideal for one light portraits or as the main light in a multi-light set up. Expect about a one stop light loss when using softboxes.
