Designed for photographers who demand professional lighting performance without sacrificing portability, the Westcott FJ100 100Ws Off-Camera Strobe with FJ-T1 S Trigger for Sony 1-Light Backpack Kit delivers a complete on-location lighting solution in an ultra-compact package. This versatile kit combines the powerful yet lightweight FJ100 strobe with the Sony-compatible FJ-T1 S touchscreen wireless trigger, FJ Mini AC/DC battery, Octa 15 softbox with 50° grid, light stand, and a padded backpack for convenient transport. Ideal for weddings, portraits, events, and mobile studio work, the FJ100 provides the reliability, speed, and creative control expected from the Westcott FJ lighting ecosystem.
At the heart of the kit is the FJ100, Westcott’s most compact FJ-series strobe, offering 100Ws of power in a body roughly the size of a soda can. Powered by the included rechargeable FJ Mini lithium-ion battery, the strobe delivers more than 700 full-power flashes per charge, making it an excellent choice for photographers working in locations where mobility and dependable performance are essential. The FJ100 features a 2.4 GHz wireless system, allowing seamless communication with other FJ-series lights and accessories, while the included FJ-T1 S trigger provides dedicated control and compatibility with Sony cameras.
The built-in 24-200mm zoom head provides precise beam control by automatically matching the attached lens focal length or allowing manual adjustment for creative lighting effects. With a 9-stop adjustable power range from 0.78 to 100Ws, TTL functionality, high-speed sync up to 1/8000 second, freeze flash, front and rear curtain sync, and stroboscopic modes, the FJ100 adapts easily to a wide variety of shooting conditions. Its fast 0.01 to 1.6-second recycle time and flash durations as short as 1/40,400 second (t0.5) allow photographers to capture fast-moving subjects with exceptional clarity.
For advanced creative control, the FJ100 includes Westcott’s exclusive Creative Mask Mode, allowing photographers to create multiple lighting combinations without physically repositioning lights. This feature is especially useful for sports, school photography, portraits, and high-volume sessions where speed and consistency are critical. Photographers can create up to six unique lighting setups using different exposure combinations, making the FJ100 a flexible tool for both beginners and experienced professionals.
The FJ100 integrates effortlessly into Westcott’s 2.4 GHz FJ wireless lighting ecosystem. Using the included FJ-T1 S trigger, photographers can remotely control flash settings, groups, and power levels directly from their Sony camera. When paired with the Westcott StudioLink app, users can adjust settings, manage lights, and access additional features from a smartphone for a streamlined wireless workflow.
An intuitive full-color LCD touchscreen makes operation quick and simple, providing easy access to power adjustments, TTL settings, grouping controls, and other functions. With 31 wireless channels, 16 groups, a range of up to 328 feet, and color-coded LED group indicators, the FJ100 makes managing multi-light setups faster and more organized, whether working with a single strobe or a complete lighting system.
The included FJ Mini AC/DC lithium-ion battery features LED power indicators and supports more than 700 full-power flashes after a 2.3-hour charge. USB-C charging and power support allow photographers to recharge or operate the strobe without interrupting their workflow. The shared battery compatibility with the FJ100 speedlight further simplifies power management for photographers using multiple Westcott lighting products.
Built for demanding professional environments, the FJ100 features intelligent heat monitoring, passive cooling, multi-stage thermal protection, and IGBT+ technology for improved performance and camera compatibility. It can deliver up to 100 consecutive full-power flashes while maintaining dependable operation, making it suitable for weddings, events, and portrait sessions. Firmware updates through the USB-C data port help ensure continued compatibility and feature improvements.
The FJ100 offers extensive light-shaping versatility with native Twist Lock modifier compatibility and support for larger Bowens-mount modifiers when paired with the optional Westcott S-Bracket 2 adapter. The included removable tilt bracket features a standard 5/8" receiver for light stand mounting, while umbrella shaft compatibility provides additional modifier options.
