Perfect Blend of Power and Portability
Building on the success of the flagship FJ400 strobe, the FJ400 II Touchscreen Strobe offers 400Ws of flash power in a compact design, striking a perfect balance of power and portability to ensure you never miss a moment.
Fastest 400Ws AC and DC Strobe

Full Color OLED Touchscreen
The full-color OLED touchscreen interface is designed for simplicity and speed, with intuitive gestures like tap, swipe, and slide for quick adjustments. Built-in help guides provide on-screen support, saving time and keeping you focused on creating.
Consistent Color Temperature
The FJ400 II maintains a color temperature stability of 5500K, throughout its entire 9-stop output range, with flash increments of either 0.1 or 1.0 stops. It features a 30W bi-color LED modeling light, adjustable from 2700K to 6500K, with auto-adjust and independent output control.
Creative Mask
With Creative Mask, you can offer your clients more variety without adding time to your shoot. Use the touchscreen to choose when each strobe fires and how many frames to capture, creating up to 6 unique lighting combinations in seconds. Ideal for fast-paced environments like sports or volume photography, where variety and efficiency are key.
Optimized for Light Modifiers
The flash’s round head and extended flash tube deliver a wide, even light spread to fill modifiers beautifully. Its Bowens mount and Rapid Box Switch Insert ensure seamless compatibility with Westcott’s extensive line of portable light modifiers. The tilter bracket also has a 9mm mount for large umbrellas.
Dedicated Sony Camera Compatibility
When paired with an FJ-X3 S Wireless Trigger, the strobe provides features including High-Speed Sync, TTL, and more. The wireless trigger is designed with a proprietary Sony hot shoe mount for Sony cameras.
Equipped with Multi-Brand Technology
The powerful FJ-X3 M Wireless Trigger is equipped with multi-brand technology that pairs with most camera brands to control FJ Wireless devices. This wireless remote offers revolutionary compatibility with many Canon, Nikon, Sony (in manual mode), Fuji, Panasonic Lumix, and Olympus cameras. See the compatibility chart for more details.
Seamless Integration with the FJ Wireless System
The FJ400 II pairs seamlessly with all flashes and triggers in Westcott’s 2.4 GHz FJ Wireless System. Control your setup with an FJ-X Trigger or FJ80 Speedlight, both compatible with major camera brands.
