The Westcott FJ100 Strobe 4-Light Backpack Kit gives Sony photographers a complete four-light wireless flash system in a remarkably portable package. Built around four ultra-compact 100Ws FJ100 Strobes, the kit includes four FJ Mini AC/DC Batteries, a dedicated FJ-T1 S Wireless Transmitter for Sony cameras, and a Lite Traveler Backpack for convenient transport. With four independently controllable lights, 700+ full-power flashes per strobe, fast recycling, touchscreen control, and advanced FJ Wireless features, this kit gives you the flexibility to build sophisticated lighting setups for portraits, weddings, events, sports, media days, and location photography.
With four independently controllable FJ100 Strobes, this kit gives you the freedom to build much more sophisticated lighting setups while keeping your equipment compact. Create dedicated key, fill, rim, background, and accent lighting, split the strobes between different areas of a venue, or combine multiple heads when you need more light. It is a flexible setup for Sony photographers who regularly move beyond a simple one or two-light arrangement.
Each FJ100 packs 100Ws of professional flash power into a body about the size of a drinks can. With four heads, you have 400Ws of combined flash output available while retaining the flexibility to position and adjust each strobe independently. Their compact size also makes the system considerably easier to transport and position than a conventional four-light studio setup.
Each FJ100 is supplied with its own 3200mAh FJ Mini AC/DC Battery, delivering more than 700 full-power flashes per strobe, per charge. USB-C charging and power support provide additional flexibility during extended sessions, while the same interchangeable battery is also compatible with the FJ100 Speedlight.
The included FJ-T1 S Wireless Transmitter is designed specifically for Sony cameras, giving you convenient wireless control of all four FJ100 Strobes directly from the camera. Assign lights to different groups and independently adjust power, sync modes, and other settings from its touchscreen interface, making even complex multi-light arrangements easier to manage.
With recycle times as fast as 0.01 seconds, flash durations down to 1/40,400 sec, and continuous capture up to 60fps on compatible cameras, the FJ100 is designed to keep pace with demanding shoots. High-Speed Sync up to 1/8000 sec, Freeze Sync, Front and Rear Curtain Sync, and TTL provide plenty of flexibility for balancing flash with ambient light or freezing fast action.
Each FJ100 features automatic or manual 24-200mm zoom, allowing you to adjust the spread of individual lights to suit their role within your setup. Native Twist Lock and umbrella mounts provide straightforward modifier compatibility, while the optional Westcott S-Bracket 2 allows you to use larger Bowens-mount softboxes and other modifiers.
Four FJ100 Strobes provide plenty of scope for taking advantage of Westcott's Creative Mask system. Choose when individual strobes fire across a sequence to create up to six different lighting combinations without physically repositioning the lights. This can be particularly useful for sports, school portraits, media days, and other high-volume environments where multiple looks need to be created efficiently.
The four FJ100 Strobes and FJ-T1 S integrate seamlessly with Westcott's wider FJ Wireless System. With support for up to 16 groups, 31 channels, and wireless operation at distances up to 100 metres, each light can be organised and controlled as part of a larger setup, with plenty of room to expand the system further.
Despite giving you four separate flash heads, the system remains highly portable thanks to the FJ100's compact design. The included Lite Traveler Backpack provides configurable storage for the strobes, transmitter, batteries, and accessories, helping keep the complete kit protected and organised when travelling between shoots.
For Sony photographers who want a genuinely portable multi-light system, this four-light FJ100 kit offers an impressive amount of flexibility. Four independently controllable 100Ws strobes let you build key, fill, rim, background, and accent lighting while the dedicated FJ-T1 S transmitter keeps control conveniently on your camera. It's a particularly strong setup for portrait, event, sports, and commercial photographers who need more advanced lighting without the bulk of a traditional four-strobe kit.
