Adjustable Lighting for Flawless Results
The FJ400-SE produces a consistent 5500K daylight-balanced flash with a 6 F-stop output range from 12.5–400Ws (1/32 power to full). Adjust power in 0.1 or 1.0-stop increments for fine-tuned exposure. A 15W LED modeling light with 5500K daylight output helps you preview light placement and composition.
Quick Setup with Creative Control
The large LCD screen, intuitive menu, and auto memory recall make setup fast and simple. This monolight flash features Manual mode with Front and Rear Curtain Sync for creative timing effects. It delivers flash durations down to 1/1200s for studio portraits, with built-in cooling and adjustable recycle modes for consistent performance on longer shoots.
Seamless FJ Wireless System Integration
A built-in 2.4GHz receiver lets you control the strobe wirelessly using any FJ Wireless trigger or speedlight, both compatible with major camera brands. With 16 groups, 32 channels, and up to 328’ (100m) of wireless range, it provides reliable communication—even in high-interference environments.
An optical sensor and sync port offer additional triggering options. Use the free Westcott StudioLink app to control your lights and access features like Mask and Delay, all from your mobile device.
