Overview

The Westcott FJ400 is a versatile AC/DC strobe designed for photographers who need reliable flash performance across a variety of shooting environments. At 400Ws, it delivers enough power for portrait, product, and event photography, while its lithium polymer battery provides over 480 full-power flashes per charge for extended location work. When you're in the studio, you can plug the FJ400 directly into an AC outlet for unlimited shooting without worrying about battery life. The sub-one-second recycle time at full power ensures you won't miss critical moments during fast-paced sessions, and at lower power settings the recycle is even faster.

The FJ400 outputs light at a consistent 5500K color temperature with plus or minus 150K variation, providing predictable results that simplify post-processing and color matching across multiple lights. Its Bowens S-Type mount opens the door to an extensive ecosystem of softboxes, beauty dishes, grids, and other modifiers from Westcott and numerous third-party manufacturers. This bundle includes the FJ400 strobe body, an AC/DC lithium polymer battery, and a microfiber cloth, giving you the essentials to start shooting right away. Whether you're setting up in a controlled studio environment or heading out to a remote location, the FJ400 is built to deliver consistent, powerful flash output wherever the shoot takes you.
