Product Description

Westcott FJ400-SE 400Ws AC-Powered Studio Strobe

The FJ400-SE is Westcott’s streamlined, AC-only version of its popular FJ400 strobe—offering essential features for studio photographers who prefer simplicity without sacrificing performance. Built with the core capabilities of the original FJ400, this manual-only strobe integrates seamlessly into the FJ wireless ecosystem, thanks to its built-in 2.4 GHz receiver. It's compatible with Westcott’s FJ triggers and speedlights (sold separately), making it a convenient addition to existing setups.

Power output ranges from 12.5 to 400Ws (1/32 to full power) in ultra-precise 0.1 or full-stop increments, delivering consistent results across a wide variety of studio needs. With flash durations as fast as 1/200 sec and quick recycle times from 0.5 to 1.0 seconds, the FJ400-SE is ideal for portrait, product, and still life photography. It comes with a 14.8' US AC power cord for plug-and-play functionality.

Streamlined Performance for Studio Simplicity

Weighing just 3.9 lb, the FJ400-SE is a lightweight, compact solution tailored for photographers who want a reliable AC-powered flash unit. It delivers consistent 5500K daylight color temperature and features a 15W LED modeling light for previewing light placement. Built with the same solid construction as the original FJ400, it’s perfect for those familiar with Westcott gear or stepping into the FJ lineup for the first time.

Reliable & Consistent Output

With its 400Ws output and compact footprint, the FJ400-SE adapts easily to different studio scenarios. Recycle times are fast—ranging from 0.5 to 1.0 seconds in Fast mode or 0.5 to 3.0 seconds in Stable mode—making it perfect for high-volume shooting. The 6-stop output range and short flash durations (t0.1: 1/200–1/300 sec; t0.5: 1/200–1/1200 sec) ensure even exposures and creative flexibility. Front and rear curtain sync allow for experimental timing effects.

Integrated FJ Wireless Ecosystem

Featuring a built-in 2.4 GHz receiver, the FJ400-SE is fully compatible with Westcott’s wireless FJ triggers and speedlights, offering 16 groups and 32 channels with wireless range up to 328'. Even in high-interference environments, the signal remains stable. Additional triggering options include an optical slave sensor and a 3.5mm sync port.

Onboard & App-Based Control

The large LCD screen and intuitive onboard interface make adjusting settings quick and easy. For added convenience, the Westcott StudioLink app allows you to control lighting, activate Creative Masking, and apply Delay functions directly from your smartphone—great for tethered shooting or fine-tuning from a distance.

Flexible Light Shaping Options

Equipped with a Bowens S-type mount and a 9mm umbrella receptacle, the FJ400-SE supports a broad selection of light modifiers including softboxes, reflectors, beauty dishes, and umbrellas. The strobe includes a tilting bracket with a 5/8" receiver for secure mounting and arrives with a 55° magnetic reflector and gel kit (CTO, 1/2 CTO, window green, diffusion, and gel frame) to shape your light and color to match ambient conditions.
