About the Aputure Storm 400x – UK Plug
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 ±6 green-magenta tint control across the complete ASC M1TC 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 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 scenes with controlled environments.
