From the manufacturer: Silverdome produces the most powerful, efficient and beautiful soft light you could ever wish for. The Silverdome's highly reflective silver interior produces the brilliant light you need for video or digital photography and the removable diffusion system allows you to modify the light from hard to soft. All four sides of the Silverdome are vented so that bottom-to-top air flow can occur with the box in either the horizontal or vertical position.
