Aputure STORM 400x Tunable White LED Monolight (V-Mount)

400W tunable white high fidelity point source lamp with ProLock Bowens mount

BLAIR: The Best Tunable White Light

The Aputure STORM 400x utilizes the BLAIR (Blue/Lime/Amber/Indigo/Red) light engine, delivering the highest quality white light and greatest +/- green adjustability of any LED technology. The BLAIR light engine’s indigo emitters enhance fluorescing materials like natural daylight and tungsten sources.

The brightness of the STORM 400x matches or exceeds that of many higher wattage LED lights.

Color Tuning Control

The revolutionary BLAIR light engine can also output saturated colors across more than 70% of Rec.2020 color space using Limited HSIC+ and x,y control modes. Achieve deep crimson sunsets, rich sodium vapor ambers, and subtle color effects without gels.

ProLock Locking Bowens Mount

The ProLock Locking Bowens mount holds modifiers and optics rigidly in place. On STORM lamps, even the heaviest modifiers stay secure and properly aligned.

Introducing the Aputure STORM 400x, a next-generation point-source LED lighting fixture that delivers professional-grade performance in a compact and robust form factor. Built upon the same innovative foundation as the STORM 1200x and STORM XT52, the STORM 400x features Aputure’s proprietary BLAIR LED chipset—an advanced five-diode design that incorporates Blue, Lime, Amber, Indigo, and Red
emitters. This cutting-edge chipset enables more efficient spectral blending and unparalleled white light accuracy.

With a powerful 400W output and compact profile, the STORM 400x is the ideal tool for users seeking versatile, color-accurate lighting solutions that can adapt to a wide range of shooting environments. Offering a broad CCT range of 2,500K to 10,000K and full ±G green-magenta tint control across the complete ASC MITC range, the STORM 400x gives users fine-tuned white point adjustment to precisely match ambient and practical sources. This level of control ensures consistent visual continuity across every scene and setup. 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 weatherresistant 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 smallcrew run-and-gun setups, the STORM 400x offers the rugged reliability, precision color performance, and intuitive control expected from Aputure’s advanced lighting ecosystem.
