While we no longer rent this product, we do carry the Westcott Rapid Box Switch 3×4 Softbox for Alienbees. You may also find alternatives in the Recommended section on the left-hand side of this page.
The PCB Foldable Giant Softbox (30×60-inch) with included speedring mounts to our AlienBees B800 / DB800, Einstein E640, and White Lightning X3200, providing a more directional yet diffused light than umbrellas can give.
