FAQ

My STORM 400x keeps showing a fan error. Can I replace just the lamp head instead of the whole light?

Yes. Aputure sells the STORM 400x Lamp Head on its own (SKU AS0706038W), and it connects to your existing STORM 400x control box with the 5-pin weatherproof head cable. Aputure's manual says to keep the lamp head attached when you update firmware so the control box and head update together.

How loud is the STORM 400x head's fan?

Aputure measures the head at 1 m: 36 dBA in Smart mode, 33 dBA in High, 29 dBA in Medium and 0 dBA in Silent mode.

How big and heavy is the STORM 400x head?

With its yoke the head measures 23.9 x 25.3 x 42.4 cm and weighs 3.95 kg. The control box is a separate 3.00 kg unit that clamps to the stand.

Will my older Bowens mount modifiers fit the STORM 400x head?

The head uses Aputure's ProLock version of the Bowens mount. A Bowens-fit modifier goes into the bayonet and the ProLock outer ring screws down onto it, so heavy modifiers stay clamped and aligned.
