The Aputure STORM 400x is a compact 400W tunable-white point-source light for interview, commercial and location crews, and it runs on AC or two V-mount batteries.

Quick Answer

The Aputure STORM 400x is a 400W tunable-white (2,500K to 10,000K) BLAIR point-source light with a ProLock Bowens mount, a separate IP65 control box and a 3 m head cable; this listing is the V-Mount battery version. It targets productions that want one powerful fixture with modern controls to serve as the key light. In a kit, it's designed as the primary key light for narrative, commercial, and event coverage, and it takes Aputure's Bowens-mount modifiers, such as fresnels, softboxes, and snoots, to shape that key.

Not Recommended For

  • Not a one-piece monolight: the lamp head runs from a separate control box on a 3 m head cable, so plan stand space for both.
