Complete 4-Light Backpack Kit
Designed for demanding on-location and studio productions, this kit includes four compact FJ100 100Ws strobes that deliver professional lighting performance in a travel-friendly form factor. Each strobe is powered by an FJ Mini AC/DC rechargeable battery capable of producing more than 700 full-power flashes per charge. Built for wedding, portrait, commercial, and event photographers, the FJ100 supports Westcott's 2.4 GHz wireless system, automatic and manual 24-200mm zoom, high-speed sync, freeze mode, and fast recycling. Color-coded LED group indicators simplify identifying and controlling multiple lights.

Portable Lighting Performance
Despite its compact, soda-can-sized design, each FJ100 delivers up to 100Ws of output with a 9-stop adjustable power range from 0.78 to 100Ws. The built-in 24-200mm zoom automatically matches your lens focal length or can be adjusted manually for precise beam control. Additional features include TTL, High-Speed Sync, Freeze, Front and Rear Curtain Sync, Stroboscopic mode, and a 2W LED modeling lamp with independent brightness adjustment. Consistent color output ensures dependable results from minimum to maximum power.

Capture Fast Action
Built for fast-paced photography, each strobe recycles in as little as 0.01 seconds and supports freeze flash durations as short as 1/40,400 sec (t0.5). High-Speed Sync enables shutter speeds up to 1/8000 second, while support for continuous shooting up to 60 fps (camera dependent) helps capture critical moments with confidence. Flash Exposure Compensation (±3 FEC) provides additional exposure control.

Creative Mask Mode
Westcott's exclusive Creative Mask feature streamlines composite photography by allowing photographers to create up to six unique lighting configurations without repositioning lights. It's an excellent solution for sports, portrait, school, and high-volume photography workflows.

Seamless Sony Wireless Integration
The included FJ-T1 S wireless trigger is designed specifically for Sony cameras and integrates seamlessly with the Westcott FJ wireless ecosystem. Control multiple lights remotely, adjust settings directly from the trigger, and expand your setup with additional FJ-compatible lighting products. When paired with the Westcott StudioLink app, you can also manage supported lighting functions directly from your smartphone.

Fast & Intuitive Operation
A bright color LCD touchscreen provides quick access to flash settings, wireless groups, TTL controls, and power adjustments. Built-in help menus simplify operation, while 31 wireless channels, 16 groups, and a wireless range of up to 328' provide flexible multi-light control. Color-coded LED indicators make identifying individual groups fast and intuitive.

USB-C Rechargeable FJ Mini AC/DC Battery
Each included FJ100 uses a removable 7.4V, 3200mAh (23.38Wh) lithium-ion battery that delivers over 700 full-power flashes per charge. Recharge in approximately 2.3 hours via USB-C, monitor remaining capacity using integrated LED indicators, or power the strobe while charging to minimize interruptions. The shared battery platform with the FJ100 speedlight simplifies power management across compatible equipment.

Built for Professional Workflows
Engineered for extended shooting sessions, each FJ100 supports up to 100 consecutive full-power flashes through intelligent thermal management. Passive cooling, multi-stage heat protection, and IGBT+ technology enhance reliability, performance, and camera compatibility. Firmware can be updated through the USB-C port to access future improvements and features.

Flexible Light Modifier Compatibility
Each strobe features Westcott's Twist Lock mount for fast attachment of compatible light modifiers. Pair it with the optional S-Bracket 2 to use Bowens-mount softboxes and modifiers weighing up to 1.3 lb. Every FJ100 includes a removable tilt bracket with a 5/8" receiver for stand mounting, along with an 8mm umbrella socket for additional lighting versatility.
