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 the bright bi-color modeling light.

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

Bi-Color Modeling Light: 30 W LED – usable as modeling, video or photo light
The integrated 30W 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 not only suitable as a modeling light, but also for video recordings or constant photo illumination, making the HS Freeze 4X a versatile light source for 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 enables 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 replaceable, so longer sessions can be easily managed 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 fully charged within 120 minutes.

Fast & intuitive – Touch display for easy operation
The high-resolution touch display of the HS Freeze 4X enables fast and precise control of all flash functions. The intuitive user interface allows 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 have an overview and can fully concentrate on your shoot – whether in the studio or on-location.

Ready to use immediately: Extremely fast recycling time of 0.01 – 0.9 seconds
The HS Freeze 4X impresses with a recycling time of only 0.01 to 0.9 seconds, so it is ready for the next flash with virtually no 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.

Capture movement: 60 fps continuous shots & 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 razor-sharp precision. 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, so that even the fastest movements – from fast 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.
