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.

What differentiates the HS Freeze 4X from its predecessor?

The HS Freeze 4X offers numerous improvements over the HS Freeze 4s: - Touchscreen control: Intuitive operation with quick access to settings. - Faster burst shooting: Up to 60 photos per second in high-speed mode (instead of 12). - Lower color temperature deviation: Improved consistency with only ±75K in standard modes. - Efficient heat management: Continuous flashing up to 180 triggers without overheating with fast recycling time. - More control through channels & groups: 31 channels (01-31) and 16 groups (A-U) for even more precise control of multiple flashes. - More powerful modeling light: 30W LED with variable color temperature (2700K–6500K) for flexible work in different environments.

Can I use the HS Freeze 4X with older Rollei flashes?

Yes, the HS Freeze 4X is fully compatible with previous Rollei flash models and can be seamlessly integrated into existing setups. Thanks to the integrated receiver, it can be controlled wirelessly with Rollei radio triggers. In addition, the photocell allows the flash to be triggered with third-party manufacturers or used as a main trigger for other flashes.

Can I charge the HS Freeze 4X during the shoot?

Yes, the flash can be charged via the power adapter during operation. This allows you to continue working seamlessly without having to take a charging break.

My flash takes a long time to recharge – what's the reason for this?

The HS Freeze 4X features automatic overheating protection to safeguard the electronics. During intensive use, such as after 180 flashes at maximum power and short intervals, the charging time initially increases to 2 seconds. After another 200 flashes, it can rise to 6-10 seconds to prevent overheating.

How can I update the firmware of my HS Freeze 4X?

The firmware can be updated via the USB-C cable. Detailed instructions and the latest firmware version can be found in the Download Center.
