Aputure STORM 400x – 400W Tunable White COB Light

The Aputure STORM 400x is a compact tunable-white point-source LED built around Aputure’s BLAIR light engine. It provides precise white-light control with extended spectral coverage for accurate skin tones and color reproduction.

The fixture delivers 400W output with a 2,500K–10,000K CCT range, ±100% green-magenta adjustment, CRI ≥95, TLCI ≥95, and SSI 87 Tungsten / 85 Daylight. Its ProLock Bowens Mount supports Bowens modifiers, while IP65 weather resistance allows operation in exposed production environments. Control is available via DMX/RDM, CRMX, Sidus Link, and onboard controls.

Suitable for key, fill, backlight, and controlled daylight applications on narrative, commercial, and location shoots. The compact lamp head works well where high-output tunable white light is required without moving to a larger fixture class.
