Studio Flash HS Freeze 4X – for perfect illumination
Maximum power, fast recycling times, and intuitive operation: This powerful 400Ws flash was specially developed for photographers and content creators who work both in the studio and on-location. With a variety of professional functions, it offers maximum control and creative freedom for every type of photography. A true hybrid talent with a bright bi-color modeling light.

Maximum power: 400 Ws – every project perfectly illuminated
The HS Freeze 4X offers an exceptional light output of 400 Ws flash power and a guide number of 72 for demanding setups. The finely graduated power control in 9 f-stops allows for precise control of light intensity – ideal for different lighting situations in the studio and on-location.

Bi-color modeling light: 30 W LED – usable as modeling, video or photo light
The integrated 30 W LED modeling light offers precise, stepless adjustment of the color temperature from 2700 K to 6500 K. This allows the light to be perfectly matched to ambient light or creative requirements – from warm artificial light to neutral daylight. The powerful LED is suitable not only as a modeling light but also for video recordings or constant photo illumination, making the HS Freeze 4X a versatile light source in a wide range of scenarios.

On-Location & Studio: Battery for 500 flashes (at full power)
The HS Freeze 4X is equipped with a high-capacity, rechargeable lithium-ion battery that allows up to 500 flashes at 400 Ws. This makes it the ideal solution for on-location shoots where reliable, wireless power supply is crucial. The battery is interchangeable, so even longer sessions can be managed without problems with spare batteries. For studio use, the flash can also be operated directly via power adapter to ensure uninterrupted use without charging breaks. The battery is charged within 120 minutes.

Fast & intuitive – Touch display for easy operation
The high-resolution touch display of the HS Freeze 4X allows for quick and precise control of all flash functions. The intuitive user interface provides direct access to power levels, flash modes, color temperature, and synchronization settings, so adjustments can be made in seconds. Thanks to the clear menu navigation, you always maintain an overview and can fully concentrate on your shoot – whether in the studio or on-location.

Ready for immediate use: Extremely fast recycling time of 0.01 – 0.9 seconds
The HS Freeze 4X impresses with a recycling time of just 0.01 to 0.9 seconds, so it is ready for the next flash almost without delay. This speed enables dynamic continuous shooting where every moment counts – ideal for action, sports, and fashion photography. Even at maximum power, the charging time remains minimal, ensuring continuous, efficient work without waiting times.

Capturing motion: 60 fps continuous shooting & flash duration up to 1/24,000 seconds
With 60 fps high-speed continuous shooting and an ultra-short flash duration of up to 1/24,000 seconds, the flash freezes even the fastest movements with pinpoint sharpness. Perfect for action, sports, and high-speed photography where every detail counts.
- Normal mode:
(t = 0.5 s): 1/600 – 1/16,000 sec. - Freeze mode for maximum precision:
(t = 0.5 s): 1/600 – 1/24,000 sec.
The Freeze mode reduces the flash duration to an absolute minimum, ensuring that even the fastest movements – from quick sports shots to splashing water droplets – are captured crystal clear without motion blur. Thanks to HSS support up to 1/8000s, the camera remains flexible – even with extremely short shutter speeds and open aperture for perfect background isolation.
