Frequently Asked Questions: Aputure STORM 400x LED Light (V-Mount)

What is the Aputure STORM 400x?

The Aputure STORM 400x is a compact, high-output 400W tunable-white point-source LED light fixture designed for film, television, and photo productions. Powered by Aputure’s breakthrough BLAIR (Blue, Lime, Amber, Indigo, Red) five-diode LED engine, it delivers daylight-matching output levels that match or exceed traditional 600W COB fixtures while maintaining color rendering and fine-tuned white point accuracy.

What is the BLAIR LED engine, and how does it benefit the STORM 400x?

The BLAIR engine replaces traditional bi-color chipsets with a five-emitter array (Blue, Lime, Amber, Indigo, and Red):

• Extended CCT Range: Provides tunable white light from 2,500K to 10,000K.

• Green/Magenta Adjustment: Offers full ±100% ASC MITC Green-Magenta tint control to match ambient or practical fixtures on set.

• Natural Fluorescing: The integrated Indigo diode excites fluorescing materials to replicate natural daylight and tungsten rendition.

• Saturated Color Modes: Supports Limited HSIC+ and x,y control modes, covering over 70% of the Rec. 2020 color gamut without gels.

What modifier mount does the Aputure STORM 400x use?

The STORM 400x features Aputure's ProLock Locking Bowens Mount. This upgraded design accepts all standard Bowens S-Type light shapers while adding a locking clamp mechanism to prevent heavy softboxes, lanterns, and optical modifiers from twisting, sagging, or shifting off-axis.

How is the Aputure STORM 400x powered on set?

The STORM 400x (V-Mount version) can be powered via two main power sources:

• AC Mains Power: Operates on standard 100V–240V AC power (500W maximum draw) using the included control box and powerCON cable.

• V-Mount Battery Power: The control box features an integrated V-Mount battery plate for location work using standard high-draw cinema batteries or 48V DC power inputs.

Is the Aputure STORM 400x weather-resistant?

Yes. The Aputure STORM 400x lamp head, control box, and connecting cables are all rated IP65 dust and water-resistant. It is fully sealed against heavy rain, dust, and harsh filming environments without requiring protective rain covers.

What control options are supported on the STORM 400x?

The STORM 400x integrates complete professional connectivity options:

• Wireless Protocols: Sidus Link and Sidus Link Pro mobile apps (Bluetooth Mesh), built-in LumenRadio CRMX (up to 100m range).

• Wired Protocols: 16-bit 5-Pin DMX512 In/Out, RDM, and dual RJ45 etherCON ports supporting Art-net and sACN.

Key Specifications Summary

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.
