Tunable white LED with BLAIR technology

The Storm 400x is built around Aputure’s BLAIR light engine, a five-colour emitter system combining Blue, Lime, Amber, Indigo, and Red. This configuration offers highly accurate tunable white light, with unprecedented +/- green control, enabling precise matching to other sources including daylight, tungsten, and legacy fixtures. The inclusion of indigo emitters boosts the performance of fluorescing materials, like natural daylight and tungsten sources.

Broad colour tuning control

The Aputure STORM 400x goes far beyond conventional bi-colour lighting by offering access to more than 70% of the Rec.2020 colour space. Whether you’re replicating rich sodium-vapour hues or deep crimson skies, the fixture allows precise tuning using both x,y coordinates and Limited HSIC+ controls. This makes it highly suitable for complex colour reproduction without reliance on gels or post-processing adjustments, saving time while maintaining creative control on set.

Built for reliable operation in various conditions

With an IP65 rating, the Storm 400x is designed for dependable performance in unpredictable environments. Weather sealing across all connection points, including the control box and cables, ensures that dust and rain won’t compromise functionality. Whether in high-humidity locations or in the rain, the Storm 400x has the protection needed for reliable shooting.

For compatibility with a range of modifiers, the ProLock Bowens mount used in the Storm 400x is engineered for secure, stable attachment of even the heaviest modifiers. This helps maintain alignment and beam shape over long shoots or when repositioning. Control options include Sidus Link Pro with Bluetooth Mesh, 5-pin DMX, and CRMX, offering compatibility with industry-standard lighting consoles and wireless control systems.

FAQs:

How compact is the Aputure Storm 400x?

Despite its high output, the Aputure Storm 400x maintains a compact footprint. The lamp head with yoke measures just 23.9 x 25.3 x 42.4 cm and weighs under 4 kg, while the control box adds only 3 kg more. This makes it highly manageable for transport, rigging in tight studio spaces, or use on location where gear size and weight are critical.

Is the Aputure Storm 400x quiet enough for sound-sensitive environments?

The Aputure Storm 400x features multiple fan modes tailored for different needs. In Silent Mode, the unit operates at 0 dBA, making it entirely inaudible, which is ideal for interviews, dialogue scenes or studio work where noise control is critical. Other modes (Smart Mode, High Mode, and Medium Mode) offer varying levels of airflow depending on thermal requirements, and operate slightly louder.

How can I update the Aputure Storm 400x’s firmware?

Firmware can be upgraded using multiple methods, including via the Sidus Link and Sidus Link Pro apps or directly through a USB-A drive. This ensures you can access improvements and bug fixes even when shooting on set or on location.

What is the wireless control range for the Aputure Storm 400x?

The Aputure Storm 400x offers robust wireless control with a range of up to 100 metres (approximately 328 feet) for both Sidus Bluetooth and CRMX (TimoTwo). This allows for reliable remote operation across large sets or outdoor locations without signal dropouts. It’s ideal for working at a distance from lights or managing multiple fixtures from a central position.
