Westcott FJ400 II 400Ws Touchscreen Strobe with FJ-X3 S Trigger for Sony (2-Light Backpack Kit)
Double Lighting with Sony Trigger
Westcott has put together this FJ400 II 400Ws Touchscreen Strobe with FJ-X3 S Trigger for Sony 2-Light Backpack Kit to give shooters two FJ400 II units with essential accessories. The kit includes a single FJ-X3 S wireless trigger for Sony cameras, plus two FJ400 II heads, each with an FJ Pro AC/DC battery, an AC adapter, a reflector, a gel set, and a Rapid Box Switch insert. A convenient backpack is provided to take it all on the road.
Compact & Reliable
The second generation of the FJ400 recycles in 0.01-0.9 sec ensuring speed and reliability while offering relevant upgrades. The FJ400 II brings improvements to its design with a 30W bi-color LED modeling light and a full-color OLED touchscreen for intuitive and uncomplicated onboard control. In addition to these upgrades, other settings are to be highlighted, including flash durations with a Freeze mode and a Creative Mask feature for better efficiency. Users will also benefit from flexible AC/DC power options with the two included interchangeable FJ Pro batteries that provide up to 550 full power flashes per charge (each). Each FJ400 II unit is a compact and rapid strobe lighting solution with little weight at 5.3 lb for great portability.
Power & Performance
The FJ400 II's 9-stop power range (1.56 - 400Ws) in 0.1 and 1.0 increments makes it readily adaptable to a variety of situations. Each flash head is backed by a 1/24,000 peak action-stopping flash duration in Freeze mode, is capable of 50 fps (camera and power dependent), and supports high-speed sync up to 1/8000 second as well as front and rear curtain sync. Users can also adjust flash exposure compensation from -3 to +3 EV. The FJ400 II was designed to suit both studio and on-location shoots.
Creative Mask Mode
In addition to basic manual and TTL flash modes, other handy settings are available, such as the Westcott Creative Mask feature, a great asset for high-volume and fast-paced shoots. This functionality gives photographers the ability to create up to six lighting combinations without moving the fixtures. Thanks to the FJ400 II's touchscreen, users can easily control when each light fires in a sequence to capture multiple dynamic looks from a single setup.
Seamless Integration
The FJ400 II is part of Westcott's 2.4 GHz FJ wireless system, meaning it can work with all FJ triggers and flashes for a cohesive lighting ecosystem. Control your setup with your FJ-X trigger for compatibility with major camera brands. The included FJ-X3 S is equipped with a proprietary Sony hot shoe mount for Sony cameras. The Westcott StudioLink app also offers wireless adjustments and advanced functionality directly from your smartphone.
Wireless 2.4 GHz Radio Frequency
The flash head has an integrated 31-channel, 16-group, 2.4 GHz wireless radio frequency with a range of 328'. The wireless system prevents interference with other photographers or to shoot several individual setups.
Interchangeable Batteries
Each FJ400 II runs on a powerful, removable 29.6V, 2500mAh AC/DC lithium-ion battery that will give you 550 full and thousands of low-power flashes on a 1.5-hour charge. Each included FJ Pro battery has LED status indicators to keep you appraised of remaining power. Users can also decide to purchase the separately available FJ ProMax battery with higher capacity to achieve up to 1000 flashes at full power. The FJ400 II's shared battery compatibility with the FJ800 unit eliminates the need for multiple power solutions, while a convenient AC trickle-charge functionality ensures uninterrupted performance during extended sessions.
30W Bi-Color LED Modeling Light
An upgraded 30W LED modeling light is employed with bi-color adjustability from 2700 to 6500K, which allows easy framing and composition.
Mounting & Firmware Updates
These monolights have a Bowens S front and come with a 5/8" tilting bracket to mount on separately available light stands, as well as a 9mm umbrella receptacle. Also, a USB-C port is present for firmware updates.
Essential Accessories
Each FJ400 II ships with a magnetic 5.5" reflector with a gel set (CTO, 1/2-CTO, window green, and diffusion). Two inserts are also included to allow the use of optional Rapid Box Switch softboxes.
Other Details
  • Consistent 5500K (±150K) color temperature
  • Extended user-replaceable flash tube for a wide and even light spread
  • IGBT+ technology for expanded camera compatibility and enhanced flash performance

Impact 45" Convertible Umbrella (White Satin with Removable Black Backing)

This is an Impact 45" Convertible umbrella with white satin and removable black backing. Umbrellas soften, broaden, and diminish the light output of any flash light source. Umbrellas with a white interior will soften and weaken light more than an umbrella with a silver lining. A white umbrella without a black backing may also be used as a makeshift softbox, although the use of the light will not be as efficient as with a softbox.

Choosing umbrella size is determined by the size of the subject, and the strength of the light supply being used. Choosing an umbrella surface is as subjective as choosing a paint and brush.

This size is perfect for a 1 - 2 person half-length portrait, or a 3x4 ft product setup.

Backing may be removed half way, providing a unique combination of light bounced from different surfaces.

Game-Changer for My Photography – Professional Results Made

By Estevan
Rated 5 out of 5

I recently purchased the Westcott FJ400 II 400Ws Touchscreen Strobe with FJ-X3 M Universal Trigger, and I can’t say enough good things about it! Not only is this strobe powerful, but it’s also incredibly intuitive—even for a beginner like me who’s just starting to work with light setups. The touchscreen and controls make learning a breeze, and it instantly gave me the confidence to take my photography to the next level. One of my favorite features is the rolling case. I recently brought this setup with me to a Texas high school Friday night football game for senior photos, and transporting it was effortless. Once set up, the results were stunning—it honestly elevated my skills of the past 4 years to a whole new professional level. Looking back, I can’t believe I didn’t buy this sooner, but I’m glad I waited for the updated version because it truly feels like Westcott thought of everything in this release. The learning curve was made even easier thanks to the wealth of helpful videos and reviews available. Purchasing through B&H was a no-brainer—they always have the latest and greatest gear in stock and ready to ship. Bottom line: These lights make me look like a pro, but more importantly, they make my photos look like they belong in a professional portfolio. Highly recommend!

Does this have a standard sync port so I can use a different receiver like a PocketWizard?
Asked by: Heather
The Westcott FJ400 II 400Ws Touchscreen Strobe with FJ Pro AC/DC Battery (B&H# WEFJ400IITSS) has a standard 3.5mm sync port that may be connected to many brands of radio receivers such as the PocketWizard PlusX Transceiver (B&H# POPWPX). Of course, only appropriate Westcott transmitters such as the Westcott FJ-X3 M Universal Wireless Flash Trigger (B&H# WEFJX3MWFT) whose signals are received by the FJ400 II's own internal receiver will support TTL, HSS, and remote intensity adjustments.

Does the FJ 400ii have a freeze mode?
Asked by: Daniel
Yes, the monolight strobes in the Westcott FJ400 II 400Ws Touchscreen Strobe with FJ-X3 M Universal Trigger (2-Light Backpack Kit) have a Freeze Mode feature. As indicated on page 15 of the instruction manual, when you are on the [MENU 2] screen, under the [SYNC] tab will be the option to set the monolight to [Freeze Mode], which allows you to capture fast-moving subjects with an ultra-short flash duration to stop motion effectively. Do note this is only available in Manual Mode only.

Does this still offer Canon RT in addition to the Westcott Canon (so I can also include Canon speedlites in a setup)?
Asked by: Patrick
The Canon RT frequency has become overcrowded in the last few years and Canon has not been able to provide a stable frequency for communication, leading to missed shots and connection loss. Therefore, for best performance we recommend either the FJ80 II or FJ80 SE Speedlights.
