The Westcott FJ800 is an 800Ws portable monolight designed for photographers who need serious power without giving up speed or flexibility. Built to handle everything from studio work to bright outdoor shoots, it combines fast recycle times, dependable colour consistency and a clear, full-colour OLED touchscreen that makes adjustments quick and intuitive. With flexible AC and DC (battery or mains) power via the included FJ Pro battery, a compact body weighing just 3.4 kg, and deep integration with Westcott’s FJ wireless system, the FJ800 is a confident, all-round lighting solution for demanding workflows.
The FJ800 delivers 800Ws of power across a 9-stop range, adjustable in either 0.1 or 1.0 stop increments. This makes it easy to fine-tune your light whether you are overpowering sunlight or working at low output for subtle studio portraits. Recycle times as fast as 0.01 seconds help you keep pace with fast-moving subjects, while Freeze mode offers flash durations as short as 1/25,000s for crisp, motion-free results.
With the included FJ Pro AC/DC battery, the FJ800 provides over 250 full-power flashes on a single charge and supports AC trickle charging for longer sessions. The battery system is shared with the FJ400 II and FJ250, reducing the need for multiple power solutions. For those who need even more capacity, an optional FJ ProMax battery is available, offering up to 500 full-power flashes.
The full-colour OLED touchscreen is designed to be quick and easy to use, with simple tap, swipe and slide gestures. Built-in help guides appear directly on screen, which is especially useful when exploring features like Creative Mask or custom sync options. LED group colour indicators on the rear of the unit make it easy to identify lights at a glance when working with multi-light setups.
Creative Mask mode allows you to program when each strobe fires and how many frames are captured, creating up to six unique lighting variations without physically moving your lights. Alongside manual and TTL modes, the FJ800 supports High-Speed Sync, Freeze Sync, front and rear curtain sync, delay functions and group exposure compensation, giving you plenty of creative freedom.
The round flash head and extended flash tube produce an even light spread that fills modifiers smoothly. A Bowens mount and included Rapid Box Switch insert ensure compatibility with a wide range of Westcott and third-party modifiers. Despite its power, the FJ800 remains portable, weighing just 3.4 kg and featuring a robust carry handle and a durable, self-monitoring cooling system.
The FJ800 is fully integrated into Westcott’s 2.4 GHz FJ wireless system, offering a range of up to 100 m with 16 groups and 31 channels. It works seamlessly with FJ wireless triggers and flashes, and can also be controlled via the Westcott StudioLink app for wireless adjustments and advanced features directly from your smartphone.
The FJ800 is a strong choice for photographers who need a single light that can confidently handle almost any situation. It offers the power to shoot in full sun, the speed to freeze action, and the control to fine-tune light precisely, all in a body that is genuinely portable. If you are invested in, or considering, the Westcott FJ system and want a dependable high-output strobe that works just as well on location as it does in the studio, the FJ800 is a very solid long-term investment.
