Studio Flash HS Freeze 1X – Professional Performance in a Compact Format
The HS Freeze 1X Studio Flash redefines mobility in flash photography. With an extremely low weight of just 705 g and impressive features including TTL and HSS, this model is the ideal tool for demanding on-location shoots. Whether for portraits, events, or weddings – the flash offers the perfect balance of power and portability.

Lightweight & portable: Speedlite-level compact design
With an operating weight of just 705 g including the battery, the HS Freeze 1X is designed for maximum portable convenience. The housing is barely larger than a conventional speedlite, yet it offers the superior lighting characteristics and endurance of a full-fledged studio flash.
Maximum power: Superior 100 Ws output
Despite its compact dimensions, the device delivers a remarkable flash output of 100 Ws. This allows for significantly higher light reserves compared to standard speedlites, which is crucial especially when shooting against bright ambient light or when using larger light modifiers.
Flexible light: 2 W LED modeling light
The integrated 2 W LED modeling light allows for an exact assessment of the shadows even before triggering. This function is essential for precise light shaping in dark environments and saves valuable time by reducing the need for test shots.
Usable anywhere: Battery operation with USB-C charging
A powerful lithium-ion battery provides a capacity of over 500 flashes at full power. The modern USB-C port enables flexible charging via power banks or power adapters, ensuring continuous readiness for use even without a direct power outlet.
Intuitive control: Modern touch display
All operations are handled via a high-resolution, responsive touch display. Supplemented by colored group LEDs, you maintain a full overview and control at all times, even in complex multi-flash setups.

Quick Freeze Mount: Flexibility for light modifiers
The innovative Quick Freeze Mount System enables fast and secure mounting of compatible light modifiers. This offers maximum creative freedom in shaping the lighting characteristics without having to carry heavy accessories.

Advanced flash modes: Maximum versatility
The system supports all relevant modes for maximum creativity: TTL, HSS, Strobe, and Freeze modes. In addition, synchronization on the first or second shutter curtain (Front/Rear-Curtain) enables impressive dynamic effects in every shot.

Universal compatibility: Mechanical & Electronic
The flash is optimized to work with the latest camera systems. It supports both mechanical and electronic shutters, which guarantees silent operation and full reliability with mirrorless system cameras.

Consistent color quality: Precise 6000 K
A stable color temperature of 6000 K (±150 K) across the entire power range guarantees color-accurate results. The effort in digital post-processing is minimized, as a consistent lighting mood is maintained throughout the entire image series.

Wireless freedom: Integrated radio system
Thanks to the integrated radio receiver, the HS Freeze 1X is fully compatible with the TR-Q8 as well as other Rollei radio transmitters. All settings can be conveniently controlled remotely directly from the camera.
