Aputure Storm 400x LED Light (V-Mount)
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 26,500 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.
