Westcott FJ800 Overview

Westcott's Compact Powerhouse
Westcott expands the FJ line by introducing the FJ800 800Ws Touchscreen Strobe with FJ Pro AC/DC Battery as the brand's most powerful monolight – made to conquer every lighting challenge. The FJ800 recycles in 0.01 to 1.8 sec ensuring speed and reliability at all times.

The FJ800 has a slightly larger body design when compared to the FJ400 II unit, but still maintains an overall compact form factor. It works as a rapid strobe lighting solution featuring a heavy-duty handle and a lightweight design at 7.5 lb for great portability.
Power & Performance
The FJ800's 9-stop power range (3.12 - 800Ws) in 0.1 and 1.0 increments makes it readily adaptable to a variety of situations. The flash head is backed by a 1/25,000 peak action-stopping flash duration in Freeze mode, is capable of 50 fps (camera and power dependent), and supports high-speed sync up to 1/8000 second as well as front and rear curtain sync. Users can also adjust flash exposure compensation from -3 to +3 EV. The FJ800 was designed for the toughest lighting conditions, giving you complete control in any lighting scenario, including bright sunlight.
Creative Mask Mode
In addition to basic manual and TTL flash modes, other handy settings are available, such as the Westcott Creative Mask feature, a great asset for high-volume and fast-paced shoots. This functionality gives photographers the ability to create up to six lighting combinations without moving the fixtures. Thanks to the FJ800's touchscreen, users can easily control when each light fires in a sequence to capture multiple dynamic looks from a single setup.
Seamless Integration
The FJ800 is part of Westcott's 2.4 GHz FJ wireless system, meaning it can work with all FJ triggers and flashes for a cohesive lighting ecosystem. Control your setup with an optional FJ-X trigger for compatibility with major camera brands. The Westcott StudioLink app also offers wireless adjustments and advanced functionality directly from your smartphone.
Wireless 2.4 GHz Radio Frequency
The flash head has an integrated 31-channel, 16-group, 2.4 GHz wireless radio frequency with a range of 328'. The wireless system prevents interference with other photographers or to shoot several individual setups.
Interchangeable Batteries
The FJ800 runs on a powerful, removable 29.6V, 2500mAh AC/DC lithium-ion battery that will give you 250 full and thousands of low-power flashes on a 1.5-hour charge. The included FJ Pro battery has LED status indicators to keep you appraised of remaining power. Users can also decide to purchase the separately available FJ ProMax battery with higher capacity to achieve up to 500 flashes at full power. The FJ800's shared battery compatibility with the FJ400 II unit eliminates the need for multiple power solutions, while a convenient AC trickle-charge functionality ensures uninterrupted performance during extended sessions.
30W Bi-Color LED Modeling Light
An upgraded 30W LED modeling light is employed with bi-color adjustability from 2700 to 6500K, which allows easy framing and composition.
Mounting & Firmware Updates
This monolight has a Bowens S front and comes with a 5/8" tilting bracket to mount on separately available light stands, as well as a 9mm umbrella receptacle. Also, a USB-C port is present for firmware updates.
Essential Accessories
The FJ800 ships with a magnetic 5.5" reflector with a gel set (CTO, 1/2-CTO, window green, and diffusion). An insert is also included to allow use of optional Westcott's Rapid Box Switch softboxes. A carry case is provided for storage and transport. You can also use the FJ800's convenient and durable handle.

Right out of the box there was a problem with the battery not taking a full charge but Westcott addressed it immediately. I shot with the defective battery until the new one arrived in just a couple days. I'm completely satisfied.
