Engineered with Aputure’s groundbreaking BLAIR (Blue, Lime, Amber, Indigo, Red) chipset, the Storm 400X offers unmatched white point accuracy and spectral performance. Its expansive CCT range of 2,500K to 10,000K is enhanced with advanced ±green/magenta tint control, covering the full ASC MITC range for precision color correction. With an output of 27,100 lux at 1 meter (5600K) using the included 35° reflector, the Storm 400X excels in both power and versatility. Versatile in power options, the Storm 400X runs on either V-Mount batteries or AC, making it equally suited for controlled studio setups and mobile, on-location shoots. It supports a wide array of control protocols including onboard adjustments, DMX, Art-Net, and etherCON, along with wireless operation via Bluetooth and CRMX for seamless workflow integration.

Color accuracy is a hallmark of this fixture, boasting CRI ≥95, TLCI ≥95, CQS ≥96, SSI (P3200) 87, and SSI (D5600) 85, with over 87% coverage of the Rec. 709 color gamut. The advanced diode mixing system ensures optimal efficiency and spectral quality across its five-chip array. Designed for professional environments, it features a rugged ProLock Bowens Mount for secure, optically aligned accessory attachment, and is IP65-rated for dust and water resistance. The Storm 400X offers smooth 0.1–100% stepless dimming with four selectable curves (Linear, Exponential, Logarithmic, S-Curve) and supports both constant and max output modes. It is designed to meet the demands of professional filmmaking, photography, and creative lighting setups. Packed with cutting-edge features—including advanced white control, high output, ultra-accurate color reproduction, and multiple control options—the Storm 400X is built for cinematic lighting precision, versatility, and durability.

Product Features in Detail

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 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.

Compact Powerhouse
The STORM 400x is surprisingly bright, with output matching or exceeding many higher-powered COB lights. Pair with the CF7 Fresnel lens for a powerful combination capable of over 23,000 lux at 3m.

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.

Professional Control Options
The STORM 400x features wireless control with Sidus Bluetooth Mesh, CRMX and 5-Pin DMX for use with professional lighting control software.

IP65 Weather Protection
Head-to-toe IP65 dust and weather protection means the STORM 400x can work in extreme environments. Seals on every connector and around components allow not only the lamphead but also the control box and cabling to be used outside in the rain.
