Westcott FJ400 400Ws Strobe AC/DC Battery EU Plugcontinues to push the envelope with the introduction of the FJ400 400Ws Strobe with AC/DC Battery. This version of the flash head has a power cord with a plug that's designed for use in most European countries. The flash head recycles in just 0.9 seconds at full power - an impressive spec for a battery-powered light. Its 9-stop power range makes it readily adaptable to a variety of situations, as do High Speed Sync, Rear Curtain Sync, and TTL capability. Speaking of TTL, the FJ400 radio receiver is compatible with many Canon, Nikon, Sony (with adapter), FUJIFILM, Panasonic Lumix, and Olympus cameras, as well as the Canon RT flash system. With separate purchase of the FJ-X2m Universal Wireless Trigger, you can make power and exposure compensation adjustments at distances up to 985'. The wireless system offers 32 channels with six groups to prevent interference with other photographers or to shoot several individual setups.

The FJ400 runs on a powerful, removable 14.8V, 4400mAh lithium-ion polymer battery that will give you 480 full and thousands of low-power flashes on a 2.5-hour charge. The battery has LED status indicators to keep you appraised of remaining power. A 20W LED modeling light is employed for minimal power drain. Alternatively, when you're shooting in the studio you can run the flash head with AC current using the included adapter. The FJ400 ships with a magnetic 5.5" reflector with three CTO filters to match other fixtures, warm ambient light conditions, or just for creative expression. A magnetic diffusion filter is included to soften the output, as is an insert that allows use of any of Westcott's Rapid Box Switch softboxes. A custom-made travel case is also provided for storage and transport.

Related Questions and Answers

Q: 1. What are the flash durations at each power level?

A: Westcott does not list the flash duration of the Westcott FJ200 Strobe at all power settings. They only list the maximum and minimum flash duration, showing the t0.1 flash duration measurement (when the light is emitting 90% of total light) in normal mode is 1/260 second at full power and 1/2600 second at minimum power, and in freeze mode, the flash duration at minimum output is 1/7000 second. At the t0.5 measurement (when the light is emitting 50% of total light), at normal mode, the flash duration would be 1/800 second at full power and 1/8000 second at minimum output power, while at freeze mode, the duration at minimum output would be 1/20,000 second. For flash duration measurement at other output settings, you would have to contact Westcott directly by e-mailing them at sales@fjwestcott.com or by calling them toll-free at 1-800-886-1689 Monday - Friday, 9am - 5pm ET.

Q: 2. Can you stack 2 colors?

A: No, Westcott FlexiGels are not stackable.

Q: 3. Will these fit on other strobes, such as Godox AD600 pro?

A: No, the Westcott FlexiGels for FJ400 Strobe fits on the specific glass dome of the FJ400.

Q: 4. Somebody asked if this uses a Bowens mount and someone replied yes. But I watched an FStoppers video for this light and Lee said it uses a smaller proprietary mount. This looks very similar to the new Godox AD300 Pro which uses a proprietary Godox mount. So which mount is this light actually using? Could it be the same as the AD300 Pro?

A: Yes you are right it is not a Bowens mount, they have not announced yet the size of the mount.

Q: 5. How long will this light continuously function properly without overheating when indoors (since there is not fan)?

A: The FJ200 Strobe is designed with passive cooling that allows the unit to perform without shutting down from overheating, no matter the environment.

Q: 6. Is this compatible with Leica SL2?

A: Yes, you may use the Westcott FJ-X2m Universal Flash Trigger for FJ400 Strobe, B&H # WEFJX2MUWLFT, included in the above Westcott FJ200 Strobe 3-Light Backpack Kit with FJ-X2m Wireless Trigger for your usage needs. When the FJ-X2m trigger is placed on the hot shoe of the Leica SL2 Mirrorless Camera, it may wirelessly trigger the FJ200 strobes in this flash kit. Do note you will have to set your flash output manually as you will not have TTL automatic flash exposure capability with the Westcott strobes (as of the date/time of this reply).
