With 81 300 lux à 1 mètre, CRI/TLCI 97 color accuracy, and a 2700K–6800K bi-color range, it’s designed for filmmakers who need professional-grade lighting both in the studio and on location.

What Makes the PRO SD650B Different?
1. Professional Output for Studio and Location Work
The PRO SD650B delivers 81 300 lux à 1 mètre with the included standard reflector, making it suitable for key lighting in studio productions, daylight fill, and large-scale commercial shoots. Le 2700K–6800K bi-color range lets you match any ambient lighting condition without gels.
2. Separate Controller with V-Mount Battery Support
Unlike all-in-one designs, the PRO SD650B features a separate controller box avec two built-in V-mount battery plates. This design offers two major advantages:
- Outdoor shooting capability: Power the light with two V-mount batteries when AC power isn’t available. When running on batteries, the light operates at half power — still more than enough for most location shoots.
