Westcott FJ800 Strobe

Higher-output FJ lighting

The FJ800 sits at the top of Westcott’s FJ monolight range, giving photographers 800Ws of flash output in a portable AC/DC head. That extra power matters when you are pushing light through larger softboxes, placing the head further from the subject or working against bright ambient light. The included 29.6V FJ Pro lithium-ion battery attaches directly to the head, so the strobe can operate without mains power and still fire up to 250 times at full output. At 3.4kg with the battery attached, it is larger than the FJ400 II, but the built-in handle makes it easier to lift, place and adjust on set.

Power range and flash speed

The 9-stop power range runs from 3.12 Ws to 800 Ws, with 0.1-stop adjustments for small exposure changes and 1.0-stop steps for faster adjustments. Recycling runs from 0.01 to 1.8 seconds, so the head recovers quickly at lower power and remains practical at full output. Freeze mode shortens the flash duration to as fast as 1/25,000 sec t.5, using the brief flash pulse to stop movement in the frame. High-speed sync up to 1/8000 sec also lets you use wider apertures or darken ambient light when shooting in brighter conditions.

Touchscreen control and group indicators

The full-colour OLED touchscreen gives direct access to the strobe’s main settings without relying on deep button combinations. You can adjust power, sync behaviour, modelling light settings and firing modes from the rear of the head. LED group colour indicators on the back make it easier to identify which light belongs to which group when several FJ units are on stands. That is useful in larger setups, because you can glance across the room and confirm which head you are adjusting before changing the lighting balance.

Modelling light and colour consistency

The built-in 30W LED modelling lamp adjusts from 2700 to 6500K. When you change its colour temperature, the visible light shifts to warmer or cooler tones, so you can frame, compose and judge shadows more easily under different room conditions. The flash output is rated at 5500K ±150K, which keeps colour steady across repeated frames and power changes. Voltage stabilisation and a self-monitoring cooling system support consistent behaviour during longer sessions.

Wireless system and Creative Mask

The FJ800 has a built-in 2.4GHz receiver with 31 channels, 16 groups and a wireless range of up to 100m. With a compatible FJ trigger, it supports manual control, TTL, front- and rear-curtain sync, flash exposure compensation, and high-speed sync across major camera systems. The StudioLink app also allows wireless adjustment from a phone, which is useful when the strobe is high on a stand or placed inside a modifier. Creative Mask controls which lights fire across a sequence, so you can capture several lighting passes from one fixed setup without moving stands.

Mounting and included accessories

The Bowens S front mount accepts a wide range of compatible softboxes, reflectors and other light shapers. A 9mm umbrella receptacle gives another simple way to spread light, while the 5/8-inch tilting bracket mounts the head on standard light stands. The supplied 5.5-inch magnetic reflector provides a direct beam from the flash head, and the gel set includes CTO, 1/2 CTO, window green, and diffusion for colour correction or a softer reflector output. The kit also includes a frosted glass dome, Rapid Box Switch / Beauty Dish Switch insert, USB cable, power adapter and storage case.
