Aputure STORM 400x Tunable White LED Monolight with Color Tuning Control (Gold Mount)
Expanding the Aputure tunable white lighting lineup, the compact STORM 400x LED Monolight is a point-source workhorse, matching a powerful full-spectrum chipset with advanced dimming, professional color accuracy, a widely adaptable Bowens mount, and robust, IP65 construction for high-end set work under any circumstance.
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 percent of Rec.2020 color space using Limited HSIC+ and x,y control modes.
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.
