Designed for filmmakers and hybrid creators working both on-set and on location, the STORM 400x combines studio-grade performance with a compact, travel-friendly build. At just under 4kg for the lamp head, it's easy to rig in tight spaces, mount on lightweight stands, or run off battery for mobile shoots.

STORM 400x vs STORM1200x: What's Improved for Mobility?

Compact & Lightweight Build

While the STORM 1200x packs more raw power, the 400x delivers exceptional punch in a far smaller footprint, perfect for gimbal setups, travel kits, or small crew productions.

ProLock Bowens Mount

Secure mounting even with heavy modifiers like large fresnels or the new Spotlight Max — no more drooping or alignment issues under weight.

Power & Output Efficiency

At 5,600K, it delivers up to ~27,100 lux bare (64,600 lux with reflector, 200,000 lux with CF7 Fresnel), offering a high output to weight ratio ideal for mobile lighting setups.

Rugged IP65 Weather Resistance

Matches the 1200x in sealing, but in a form that’s easier to pack for outdoor shoots in rain, dust, or extreme conditions.

Cinematography-Ready Features

Full-Spectrum Colour: High CRI/TLCI (95), excellent SSI (85-87) for both daylight and tungsten, ensuring skin tones render naturally.
