Replacement Flash Tube for FJ400 Strobe

The Westcott FJ400 Flash Tube #4710 is a user-replaceable component built for the FJ400 strobe. It installs in seconds without tools, keeping downtime to a minimum during shoots. This genuine Westcott part maintains the original colour accuracy and output consistency of the lighting system. It suits photographers and videographers who need a reliable spare or a fresh tube after extended use.

400Ws Output with High Flash Capacity

The tube delivers a robust 400Ws lamp wattage for powerful, consistent illumination across a 9-stop output range. It supports over 480 full-power flashes per charge, providing ample headroom for long sessions. Recycling at full power takes less than one second, keeping pace with fast workflows. Very high-volume bursts or continuous video lighting will eventually exceed the per-charge count.

Durable Build with Universal Trigger Compatibility

Crafted for durability, the tube withstands regular handling and replacement cycles. It works with the Westcott FJ-X2m universal wireless trigger and the Canon RT system for flexible triggering options. The strobe features Manual and TTL modes, High Speed Sync up to 1/8000s, and Freeze Sync up to 1/19000s via an intuitive LCD menu. Users without compatible triggers cannot access wireless or TTL functions.

Questions about this item

Will the FJ400 flash tube work with my existing Westcott FJ400 strobe?

Yes, the FJ400 flash tube is designed as a user-replaceable component for seamless integration with the FJ400 strobe, allowing quick installation in seconds.

How can I verify the flash tube is performing correctly after fitting it?

The strobe’s LCD colour display shows output settings across the 9-stop range; you can confirm consistent 400Ws output and recycle times under one second at full power.

Does the #4710 package include the strobe body or wireless trigger, or must I buy them separately?

The #4710 item is the flash tube only; the FJ400 strobe body and FJ-X2m trigger or Canon RT system are separate purchases.
