Westcott FJ100 Touchscreen Speedlight Flash (100Ws)

More Power Than the FJ80 II. In a Smaller Body.

The FJ100 Speedlight delivers a full 100Ws from a round Omega flash tube, and it does it from a smaller housing than the FJ80 II it sits above — 7.5 × 3 × 3 inches, 1.3 lbs. It recycles in as little as 0.01 seconds, runs 575+ full-power flashes on one charge of the included FJ Mini AC/DC Battery, and drives the whole thing from a 2" color LED touchscreen on the back.

For wedding and event shooters, that means one flash on camera, three more on stands across the reception hall, and no battery swap between the ceremony and the send-off.

Round Omega Head, 24–200mm Zoom, Full Articulation

The round Omega flash tube produces smooth, even light with natural-looking falloff — the quality that makes bounced flash read like window light instead of flash. The head tilts 90° vertically and rotates a full 360° horizontally, so you can bounce off a ceiling, feather a wall, or aim straight through a modifier.

The built-in 24–200mm zoom automatically matches your lens focal length, or gets set by hand when you want to control the spread yourself.

Choose Your Mount: Multi-Brand or Sony

• Multi-Brand (5750M): TTL compatibility with Canon, Nikon, FUJIFILM, Panasonic Lumix, and Olympus cameras, plus Sony in manual mode
• Sony (5750S): dedicated Sony version for native Sony TTL through the Multi Interface shoe

Both mount through a robust all-metal hot shoe that holds a reliable connection every time you shoot.

On Camera, Off Camera, or Running the Whole Room

The integrated 2.4 GHz transceiver means the FJ100 Speedlight works three ways: as an on-camera flash, as the wireless transmitter controlling your whole setup, or as an off-camera wireless client on a stand.

Control extends across 16 groups and 31 channels at ranges up to 328 ft (100 m), with color-coded LED group indicators so you can identify lights at a glance. Flash power displays in stops or fractions — set it to match how you already think.

575+ Full-Power Flashes, and USB-C When You Need More

The removable 3200mAh FJ Mini AC/DC Battery delivers 575+ full-power flashes per charge, which is industry-leading battery performance in its class. Charge or power the FJ100 over USB-C to keep shooting through long events and portrait sessions without interrupting your workflow.

The same interchangeable battery also powers the FJ100 Strobe, so a two-light kit needs one battery type and one charger.

Fast, Consistent, and Built to Take a Full Wedding Day

• Recycle time: 0.01 to 1.6 seconds
• Continuous capture: up to 60 FPS (camera dependent)
• Consecutive full-power flashes: up to 100, with intelligent self-monitoring heat protection
• Freeze flash duration: as short as 1/55,600 sec
• High-Speed Sync: up to 1/8000 sec

Accurate 5800K (±200K) color stays consistent across the full 9-stop power range, adjustable in 0.1 or 1.0-stop increments for predictable, repeatable results. IGBT+ technology improves flash control, sync speeds, and compatibility with DSLR and mirrorless bodies.

Every Sync Mode You'd Actually Use

Manual and TTL. High-Speed Sync up to 1/8000 sec. Freeze Sync. Front and rear curtain sync. Stroboscopic Mode captures multiple stages of movement in a single exposure. Firmware updates arrive over USB-C, so the flash keeps current with the latest improvements.

Modifiers Without Adapters

The FJ100 Speedlight mounts Westcott Twist Lock modifiers natively — domes, grids, snoots, barndoors, the Octa 15. Add the optional Quick-Mount S-Bracket 2 to run Bowens-mount softboxes and support larger Cheetah Stand softboxes.

Off camera, use the built-in cold shoe or the included shoe stand with a 1/4"-20 threaded receiver to get it onto a Cheetah Stand in seconds.

The built-in 3W LED modeling light (5500K ±200K) gives you continuous illumination with independent brightness control and auto-adjust, so you can preview your lighting before you fire.

One System That Grows With You

The FJ100 Speedlight integrates with every strobe, speedlight, trigger, and receiver in the FJ Wireless System. Buy one for the hot shoe today. Add an FJ100 Strobe for the reception next year. They share the battery, the interface, and the radio.
