Westcott FJ400 Overview

Westcott continues 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 the US and North America. 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.

The wireless system offers 16 channels with 10 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.

Wide Wireless TTL Compatibility
The FJ400's built-in TTL receiver is compatible with many Canon, Nikon, Sony (with adapter), FUJIFILM, Panasonic Lumix, Olympus cameras, and the Canon RT flash system. Make adjustments to the FJ400 from distances up to an impressive 985' with the separately-purchased Universal Wireless Radio Trigger.
Rechargeable, Removable, Powerful LiPo Battery
The FJ400's 14.8V, 4400mAh lithium-ion polymer battery is a removable power source that will provide 480 full power flashes on a 2.5-hour charge. LED charge status lights keep you appraised of the battery's remaining power. Alternatively, when shooting in the studio, you can power the light with the included AC adapter.

Westcott FJ400 Reviews

Battery Failed

By Rooks
Rated 1 out of 5
Date: 2023-02-24

Bought this in January 2021 and used it maybe 20 times... the battery already failed. I cannot charge it or get it to work while plugged in. That being said, I loved this light before the battery failed.

Outstanding portable light

After having used this a couple of times already I am impressed with the quick recycle time as well as how long the battery lasts when shooting on location. This is my second Fj400 cause I liked the first one I bought so well.

Game Changer

By Johnnyray

This is my first Strobe and I've gotta say, it is super simple to use and such a Game Changer when it comes to Image Quality. After using this I don't know how I lived without it for so long.

Outstanding Strobes, Outstanding System!

By Paul
Rated 5 out of 5

I absolutely love the Westcott FJ400s. Big, easy to read display, easy to navigate menu, battery-friendly LED modeling lights, and, most importantly, GREAT strobe lighting. Having the battery pack included opens numerous options for location lighting. Using the transmitter with these is simple and effective. The Bowens mount is solid and gives you endless modifier options. The only thing that I think can possibly be improved is the mount. It's not inherently bad, but the lightweight plastic feels like it could be a weak point. I used Elinchrome strobes for years, but Westcott won me over with this outstanding system.

Very Nice

Love these but a couple notes... 1) Westcott, please for the love of god spend 2 more bucks and spring for better plastic material! Cheap plastic is very frustrating to see in products like this. The feel, texture, and durability for just a little less profit is so worth it. I would gladly pay more for a better feel... even if it doesn't make the performance any better. 2) Even though its kinda cheap plastic, the flashes internal parts are well made and performance was awesome! Make sure you update the firmware before testing... my flashes kept missing at about 25%, but once I did a firmware update they are solid.

I love this strobe! In fact, I have 2 of them. It recycles so fast that you can just continuously pop shots off. I've used it in many different environments from outdoor to indoor. I also love that I can use my Canon transmitter to control the Westcott. It comes in a nice compact case.

Asked by: Eric
Westcott has not disabled this compatibility. The ST-E3-RT DOES in face operate the FJ400 Strobe. It is done simply by matching groups, channels, and ID number of the ST-E3-RT and that of the FJ400.

Can you run this off AC power without the battery attached?
Asked by: Elizabeth
No, the AC power input is on the back of the battery. This allows you to charge the battery while shooting, so that you have a full battery when you want to be more portable.
