Westcott FJ400 II 400Ws Touchscreen Strobe with FJ-X3 M Universal Trigger | 2-Light Hard Case Kit
The FJ400 II 400Ws Touchscreen Strobe with FJ-X3 M Universal Trigger 2-Light Hard Case Kit from Westcott provides a comprehensive strobe lighting solution for on-location work. The kit includes two FJ400 II heads, each equipped with an FJ Pro AC/DC battery, an AC adapter, a reflector, a gel set, and a light stand that reaches a maximum height of 8 feet. Additionally, the Westcott FJ-X3 M universal wireless trigger is included, along with Rapid Box Switch Octa-M and Strip 1 x 3 softboxes, both featuring inserts. All components can be conveniently packed in a wheeled hard case for easy storage and transport.
Compact & Reliable
The second generation of the FJ400 operates with a recycling time of 0.01-0.9 seconds, ensuring both speed and reliability while incorporating significant upgrades. The FJ400 II enhances its design with a 30W bi-color LED modeling light and a full-color OLED touchscreen, facilitating intuitive and straightforward onboard control. Furthermore, additional settings warrant attention, such as flash durations featuring a Freeze mode and a Creative Mask function aimed at improving efficiency. Users will also enjoy the advantage of versatile AC/DC power options, thanks to the two included interchangeable FJ Pro batteries, which offer up to 550 full power flashes per charge (for each battery). Each FJ400 II unit serves as a compact and swift strobe lighting solution, weighing only 5.3 lbs, which contributes to its excellent portability.
Power & Performance
The FJ400 II features a versatile 9-stop power range (1.56 - 400Ws) with increments of 0.1 and 1.0, allowing it to be easily adapted for various scenarios. Each flash head is equipped with a peak action-stopping flash duration of 1/24,000 in Freeze mode, can achieve 50 fps (depending on the camera and power), and supports high-speed sync up to 1/8000 second, along with both front and rear curtain sync. Additionally, users have the ability to modify flash exposure compensation from -3 to +3 EV. The FJ400 II is specifically designed to accommodate both studio and on-location photography.
Creative Mask Mode
Alongside the fundamental manual and TTL flash modes, there are additional useful settings, including the Westcott Creative Mask feature, which is particularly beneficial for high-volume and fast-paced photography sessions. This feature enables photographers to generate as many as six different lighting combinations without the need to reposition the fixtures. With the FJ400 II's touchscreen interface, users can conveniently manage the timing of each light's activation in a sequence, allowing for the capture of various dynamic appearances from a single arrangement.
Seamless Integration
The FJ400 II is an integral component of Westcott's 2.4 GHz FJ wireless system, allowing it to function seamlessly with all FJ triggers and flashes, thereby creating a unified lighting ecosystem. You can manage your setup using the FJ-X trigger, which ensures compatibility with leading camera brands. The provided FJ-X3 M features multi-brand technology that connects with a majority of camera brands, including Canon, Nikon, FUJIFILM, Panasonic Lumix, and Olympus. Additionally, the Westcott StudioLink app provides wireless adjustments and enhanced 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 operates on a robust, detachable 29.6V, 2500mAh AC/DC lithium-ion battery, providing 550 full flashes and thousands of low-power flashes on a 1.5-hour charge. The FJ Pro battery included with each unit features LED status indicators to inform users of the remaining power. Additionally, users have the option to purchase the FJ ProMax battery, which offers a higher capacity for up to 1000 flashes at full power. The shared battery compatibility of the FJ400 II with the FJ800 unit removes the necessity for multiple power solutions, while the convenient AC trickle-charge functionality guarantees uninterrupted performance during prolonged 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 the included light stands, as well as a 9mm umbrella receptacle. Also, a USB-C port is present for firmware updates.
