Overview

The Westcott FJ400 Strobe Wireless Flash Kit is a comprehensive lighting package designed for photographers who want professional-grade flash capability without the hassle of piecing together separate components. At its core is the FJ400 strobe, delivering 400Ws of power with a consistent 5500K (±150K) color temperature that ensures accurate, repeatable color from shot to shot. The 9-stop output range gives you precise control over light intensity, from a gentle fill at minimum power to full output for overpowering ambient light or illuminating larger scenes.

Speed is a defining feature of the FJ400, with recycle times as fast as 0.05 seconds at lower power settings and just 0.9 seconds at full output. This allows photographers to keep pace with fast-moving subjects during events, portraits, and editorial shoots. The strobe supports TTL automatic metering, manual control, high-speed sync for shooting with wide apertures in bright conditions, and Freeze Sync for capturing motion. The included FJ-X3m 2.4GHz wireless trigger provides reliable connectivity across multiple camera brands. Rounding out the kit are a rechargeable battery capable of over 480 full-power flashes, a magnetic reflector with color gels, dome diffuser, Rapid Box insert for softbox compatibility, a tripod, carrying case, USB-C charging cable, and a 64GB SD card — making this a true grab-and-go lighting solution.
