Westcott FJ400 400Ws Strobe with Rapid Box Switch Strip Softbox (1x2'), FlexiGels, and Accessory Kit

Westcott Rapid Box Switch Strip Softbox (1x2')

The Westcott Rapid Box Switch (1x2') Softboxes are large collapsible softboxes with reflective silver interiors and diffusion panels for modifying speedlites or strobes.

A Perfect Edge Light, Rim Light or Hair Light

Because of their long and narrow profiles, Westcott's Rapid Box Switch strip softboxes offer precise control over your light source. They're ideal for hair, rim or edge lights and are perfectly paired with optional egg-crate grids.

The Softbox That Changes With You

The Rapid Box Switch is designed for use with the most popular strobes, speedlites and monolights. With 13 interchangeable light mount inserts and 9 collapsible light modifiers, this is the premier softbox series that Switches with you.

1. Choose your Switch modifier

  • 9 unique sizes and shapes with new 1x4, 2x3, and 3x4 options

2. Choose your Switch Insert

  • 13 quick-release interchangeable light mount options

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.

Heavy-Duty Mounts for the Most Popular Lights

Switch Inserts attach your light source to any Rapid Box Switch light modifier in an instant. This durable all-metal adapter slides quickly into the rear tabs of your Rapid Box Switch and secures in place with the thumb-lock.

The removable lithium polymer battery provides both DC power for on-location freedom and AC trickle-charge performance when the state of charge is above 25%.

Adjustable Color Temperature

The Westcott FJ400 400Ws Strobe maintains a color temperature stability of 5500K (±150K) throughout its entire 9-stop output range, with flash increments of either 0.1 or 1.0 stops. It features a 20W 5600K LED modeling lamp with auto-adjust and independent output control. Designed with safety in mind, it is equipped with onboard self-monitoring cooling fans and an automatic shutoff feature to ensure safe operation during use.

Complete System

The extended flash tube provides optimal light output allowing for a wider, even spread for filling light modifiers. Equipped with a Bowens S-Type mounting system, the FJ400 can be easily paired with your favorite softbox. The strobe light also includes a magnetic 5-inch reflector, magnetic CCT gel set, and a Rapid Box Switch Bowens insert. The Bowens insert allows you to pair your strobe with any Rapid Box Switch light modifier.

Complete System

The built-in tilter bracket with a tension screw offers secure mounting and positioning of large umbrellas and modifiers. The included USB-C to USB-A cable lets you install firmware updates. A sleek travel case houses all of the FJ400 Strobe’s components for safe transport and storage. Pair the FJ400 Strobe with Westcott’s FJ-X2m Universal Wireless Trigger (sold separately) for revolutionary compatibility with most Canon, Nikon, Sony (with adapter), Fuji, Panasonic LUMIX, and Olympus cameras.

Westcott FlexiGels for FJ400 Strobe Light with Silicone Rubber Body and Durable Design (Vivid Pack)

With the Westcott FlexiGels Vivid Pack for FJ400 Stribe Light, you can give your images a striking splash of color without having to deal with the hassles of typical film-based gels. Their patent-pending design adds vibrant color to your subject and scene instantaneously by sliding it simply over the glass dome of the strobe. Vivid Red, Orange, Yellow, Green, Teal, Blue, Purple, and Pink are among the eight color gels in this collection. By varying the power level of your light, you may produce a variety of color intensities using a single gel.
Seamless Compatibility
The final color gels you will ever need to purchase are FlexiGels. Slide one of these flexible rubber gels on for countless imaginative lighting possibilities. Made of silicone rubber, they are strong, resistant to heat, and fit over the glass dome of the FJ400 strobe like a glove. It doesn't take clips or gaff tape to hold them in place. Third-party strobes with a glass dome measuring 2 inches in height and 3.4 inches in diameter and properly aligned ventilation holes can be used with FlexiGels.
How to Use
You are set to shoot after mounting your light modulator and attaching a FlexiGel to your FJ400 strobe. They work well with softboxes, umbrellas, and Rapid Box Switch, among other light modifiers. After your photo shoot is over, let your FJ400 cool for a minimum of five minutes before taking the gel off. To store the FlexiGel without lint, simply slide it off your strobe and place it in the microfiber case that comes with it.
