If you shoot commercial work, you know the struggle. Studio lights are powerful but stuck near a wall outlet. Battery-powered options are portable but lack the punch. And anything with Controle DMX usually costs more than your camera.
The GVM PRO SD650B is a 650W bi–color COB light that offers a different path. It delivers 81.300 lux a 1 metro with the standard reflector, a 2700K–6800K bi-color range, 97+ CRI, and built-in Controle DMX — plus a separate controller box that accepts two V–mount batteries for location work. It’s a continuous light that doesn’t force you to choose between studio power and outdoor flexibility.

Why the SD650B Stands Out
650W of Output for Studio and Location
At 650W, the SD650B delivers 81.300 lux a 1 metro with the included standard reflector. That‘s enough to serve as a key light for interviews, a fill light for product shots, or the primary source for commercial sets. The 2700K–6800K bi-color range lets you match ambient lighting without gels.
Com CRI/TLCI de 97+, skin tones look natural straight out of camera — minimizing post-production color correction.
Separate Controller with V–Mount Battery Support
Unlike all-in-one designs, the SD650B uses a separate controller box with two V–mount battery plates. This design offers two advantages:
- Location shooting: Power the light with two V-mount batteries when AC power isn’t available. In battery mode, the light runs at half power — still more than enough for most location shoots.
- Reduced head weight: The controller attaches to the light stand via the included clamp, keeping the fixture itself lighter and easier to adjust.
DMX Control for Professional Setups
The SD650B supports DMX–512 with both 8–bit and 16–bit precision, making it compatible with professional lighting consoles and multi-light setups. For film sets and broadcast studios where synchronized control matters, this is a feature you usually only find on fixtures costing far more.
12 Light Source Presets and 12 Effects
The SD650B includes 12 built–in light source presets for quick scene matching, and 12 cinematic lighting effects — including lightning, TV, paparazzi, candle, explosion, and more. The intensity and rate of each effect can be customized.
Advanced Cooling System
The SD650B features an active cooling system with three fan modes: Smart (auto-adjusts based on temperature), High (maximum cooling), and Silent (low noise for sound-sensitive environments).
Who Is the PRO SD650B For?
| User Type | Why It Fits |
| Cinematographers | 650W output, 97+ CRI, DMX control for professional sets |
| Broadcast studios | Consistent color, DMX integration, reliable performance |
| Commercial production crews | V-mount battery support for location shoots |
| Documentary filmmakers | Portable with batteries, robust build |
| Gaffers and lighting directors | DMX-512, 16-bit precision, Mesh networking |
| Content creators with studios | Bi-color flexibility, effects, APP control |
