Bi-Color Modeling Light: 30 W LED – usable as modeling, video or photo light

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.

Was unterscheidet den HS Freeze 4X von seinem Vorgängermodell?

Der HS Freeze 4X bietet zahlreiche Verbesserungen gegenüber dem HS Freeze 4s: - Touchscreen-Steuerung: Intuitive Bedienung mit schnellem Zugriff auf Einstellungen. - Schnellere Serienaufnahmen: Bis zu 60 Fotos pro Sekunde im High-Speed-Modus (statt 12). - Geringere Farbtemperaturabweichung: Verbesserte Konstanz mit nur ±75K in Standardmodi. - Effizientes Wärmemanagement: Kontinuierliches Blitzen bis zu 180 Auslösungen ohne Überhitzung mit schneller Ladezeit. - Mehr Kontrolle durch Kanäle & Gruppen: 31 Kanäle (01-31) und 16 Gruppen (A-U), um mehrere Blitze noch präziser zu steuern. - Leistungsstärkeres Einstelllicht: 30W LED mit variabler Farbtemperatur (2700K–6500K) für flexibles Arbeiten in verschiedenen Umgebungen.

Kann ich den HS Freeze 4X mit älteren Rollei Blitzen verwenden?

Ja, der HS Freeze 4X ist vollständig kompatibel mit früheren Rollei Blitzmodellen und kann nahtlos in bestehende Setups integriert werden. Dank des integrierten Empfängers lässt er sich drahtlos mit Rollei-Funkauslösern steuern. Zudem ermöglicht die Fotozelle, den Blitz auch mit Fremdherstellern auszulösen oder als Hauptauslöser für andere Blitze zu nutzen.

Kann ich den HS Freeze 4X während des Shootings laden?

Ja, der Blitz kann während des Betriebs über das Netzteil geladen werden. So kannst Du nahtlos weiterarbeiten, ohne eine Ladepause einlegen zu müssen.

Mein Blitz braucht lange, bis er wieder bereit ist – woran liegt das?

Der HS Freeze 4X verfügt über einen automatischen Überhitzungsschutz, um die Elektronik zu schützen. Bei intensiver Nutzung, beispielsweise nach 180 Blitzen bei maximaler Leistung und kurzen Intervallen, verlängert sich die Ladezeit zunächst auf 2 Sekunden. Nach weiteren 200 Blitzen kann sie auf 6–10 Sekunden steigen, um eine Überhitzung zu vermeiden.

Wie kann ich die Firmware meines HS Freeze 4X aktualisieren?

Die Firmware kann über das USB-C-Kabel aktualisiert werden. Detaillierte Anweisungen und die neueste Firmware-Version findest Du im Download-Center.
