High Output:
Up to 27,100 lux at 1 meter when used with the included 35° reflector—suits a range of production needs.
Rugged Weatherproof Design:
IP65 rating ensures reliability in harsh conditions; ProLock Bowens mount secures heavy modifiers safely to the housing.
Advanced Control & Cooling:
Stepless 0.1–100% dimming, four fan modes (Smart, High, Medium, Silent), and control via Sidus Link apps, DMX, CRMX, or wired interfaces.
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.
The revolutionary BLAIR light engine can also output saturated colors across more than 87% of Rec. 709 color gamut using Limited HSIC+ and x,y control modes. Achieve deep crimson sunsets, rich sodium vapor ambers, and subtle color effects without gels.
The ProLock Locking Bowens mount holds modifiers and optics rigidly in place. On STORM lamps, even the heaviest modifiers stay secure and properly aligned.
