Designed for Portability

Constructed with solid aluminum umbrella-inspired framework, the design of the Rapid Box Switch maximizes durability, minimizes weight, eliminates the need for separate support rods, and makes setup a breeze. Everything is simple, quick, and compact. After your shoot, the Rapid Box Switch breaks down instantly into a sleek carry case for travel and storage.

An Ingenious Light Modifier

Pairing durable fabrics with a quick-collapse frame, Westcott's Rapid Box Switch softboxes offer the professional light modification that you're looking for without the tedious setup.

Premium Diffusion Fabric

Westcott's diffusion panels are constructed with an all-natural, unbleached nylon fabric. Unlike processed diffusion fabrics, these diffusers will soften your light source without altering its color temperature.

The Must-Have Accessory

The optional Deflector Plate minimizes hot spots and creates a stunning beauty-style light output. These plates are easy to use with all Rapid Box softboxes.

Rear-Mounted Lights

Westcott purposely designed the Rapid Box Switch with an external mount. By keeping your speedlight or strobe outside of the softbox, you can quickly access controls and utilize the line-of-sight (or optical wireless) functionality. Of course, radio triggers can be used as well.
