Aputure STORM 400x BLAIR-CG LED Light

The Aputure STORM 400x is a powerful 400W point-source LED fixture designed for professional film, broadcast, television, and content production. Built on the same advanced platform as the acclaimed STORM 1200x and STORM XT52, the STORM 400x incorporates Aputure’s revolutionary BLAIR (Blue, Lime, Amber, Indigo, Red) LED chipset, delivering exceptional colour accuracy, superior spectral output, and industry-leading white light performance.

Combining high output with a compact and rugged design, the STORM 400x is engineered to perform in demanding production environments. Its IP65 weather-resistant construction protects against dust and rain, while integrated CRMX wireless control enables seamless operation within professional lighting workflows. The fixture also features Aputure’s ProLock Bowens Mount, providing a secure connection for a wide range of lighting modifiers.

With an extensive 2,500K to 10,000K colour temperature range and full ±G green-magenta tint adjustment across the ASC MITC range, the STORM 400x offers precise control for matching ambient light, practical fixtures, and mixed lighting conditions. Whether shooting in the studio or on location, users can achieve consistent colour reproduction and maintain visual continuity across every scene.

Designed for cinematographers, gaffers, broadcasters, and content creators, the Aputure STORM 400x delivers the versatility, reliability, and colour fidelity required for today’s professional productions. It is an ideal lighting solution for interviews, commercials, documentaries, narrative filmmaking, live events, and virtual production environments.

Thanks to its advanced diode architecture and optical design, the STORM 400x achieves an impressive 27,100 lux at 1 meter (5600K) when using its included 35o reflector. This output is paired with industry-leading color metrics: CRI and TLCI ≥95, CQS ≥96, SSI (Tungsten) 87, SSI (D56) 85, and average TM-30 scores of Rf 95 and Rg 100. This makes it a reliable fixture for color-critical work. With over 87%

Rec. 709 color gamut coverage and smooth 0.1–100% stepless dimming, the STORM 400x excels in both creative expression and technical consistency.

Built for demanding workflows, the STORM 400x is housed in an IP65 weather- resistant body and features Aputure’s ProLock accessory system, offering enhanced accessory security and optical alignment when working with heavier or optical modifiers. Its intelligent cooling system includes four fan modes: Smart, High, Medium, and Silent. This allows users to optimize output based on shooting noise conditions.
Equipped with extensive control capabilities, including Sidus Link® and Sidus Link Pro® app compatibility, LumenRadio CRMX, and 16-bit DMX512 in/out, the STORM 400x integrates effortlessly into complex lighting networks and console- controlled environments.

Whether you’re working on high-end film productions, commercial shoots, or small-crew run-and-gun setups, the STORM 400x offers the rugged reliability, precision color performance, and intuitive control expected from Aputure’s advanced lighting ecosystem.
