Ensure your Godox AD400Pro flash continues to perform at peak power by equipping it with the Godox FT-400Pro 400W Spare Flash Tube — a genuine replacement part built to the original manufacturer’s standards. Flash tubes are the heart of your strobe, generating the burst of light that defines your exposure. Over time and heavy use, tubes can degrade or fail, leading to inconsistent output or reduced efficiency. This 400W rated spare tube provides a quick and effective solution to restore performance without needing to replace the entire flash unit.

Easy to install, the FT-400Pro can be swapped in by simply removing your old tube from the AD400Pro flash head and replacing it with this genuine tube. Once installed, you’ll regain the full brightness, color consistency, and fast recycle performance that Godox lights are known for.

Whether you’re shooting portraits, events, product stills, or dynamic outdoor scenes, this spare tube helps maintain reliable flash performance so you can shoot with confidence. Keeping a spare on hand is ideal for professional photographers and videographers who rely on off-camera flash for consistent lighting — especially during long sessions where tube failure can interrupt workflow.
