400W Tunable-White Point Source

The Aputure STORM 400x is a 400W compact point-source fixture built around a proprietary BLAIR LED chipset that blends Blue, Lime, Amber, Indigo and Red emitters. It delivers a CCT range of 2,500K-10,000K with advanced white-point control and full ASC MITC green/magenta correction at +/-G 100%. The unit suits cinematographers and studio photographers who need precise colour fidelity from a single high-output head.

Sustained Output and Colour Volume

Under continuous operation the STORM 400x maintains output that matches or exceeds many higher-wattage COB lights, reaching over 23,000 lux at 3m when paired with the CF7 Fresnel lens. The BLAIR engine covers more than 70% of the Rec. 2020 colour space in Limited HSIC+ and x, y modes, enabling deep saturated hues without gels. ProLock Locking Bowens Mount keeps heavy modifiers rigidly aligned during long sessions.

Mounting and Control Compatibility

Verify that your rig can accept a ProLock Locking Bowens Mount modifier and that your power distribution supports a 400W draw with Gold-Mount battery plates. Wireless operation relies on Sidus Bluetooth Mesh and CRMX, so confirm your control ecosystem integrates those protocols. The fixture is not suited for buyers who need a multi-head kit or built-in battery operation.

Questions about this item

How quiet is the STORM 400x when it runs continuously at 400W?

The fixture uses an advanced cooling system designed for sustained 400W output, keeping fan noise low enough for sound-sensitive sets while maintaining stable colour accuracy across the full 2,500K-10,000K range.

Which power source do I need to run the Gold-Mount version of this light?

The Gold-Mount plate accepts standard Gold-Mount batteries, so you must already own a compatible battery and charger to operate the fixture away from mains power.

Will my existing Bowens-mount modifiers lock securely onto the ProLock mount?

Yes, the ProLock Locking Bowens mount engages the same bayonet lugs as older modifiers and adds a locking ring that prevents even heavy Fresnel lenses from rotating or loosening during use.
