The GVM 1200D is a professional RGB LED video light designed for studio, outdoor, and live broadcast use. Before operation, ensure the light is placed on a stable stand and the protective cover is removed. The device operates within a temperature range of -10°C to 40°C and is not waterproof. Always use the provided power adapter or two compatible lithium batteries for power.
Product Structure
The light features a U-frame for 360° rotation and adjustable barn-doors to shape the light output. The rear panel contains the LCD screen, battery tanks, adapter interface, and control knobs for brightness, color temperature, hue, and saturation.
Installation Method
To mount the light, place it on a compatible light stand and secure it by rotating the lamp holder fixing knob clockwise. Loosen the adjustment knobs on both sides of the U-bracket to tilt the panel to the desired angle, then tighten the knobs to lock it in place.
Power Supply
The unit supports two power modes:

- AC Power: Connect the provided power cord and adapter to the DC15V interface.
- Battery Power: Install two suitable lithium batteries into the battery slots. Both batteries must be installed for the unit to function.
Control Modes and Operation
Use the Mode button to cycle through control modes:

- Rotate Mode: Adjust lighting effects directly using the dimming knobs on the unit.
- Master Mode: Adjust settings on the unit; connected slave units with the same channel will synchronize automatically.

Use the multifunctional knob to switch between CCT (Color Temperature), HUE, and SAT (Saturation) modes. Rotate the knob to adjust the selected value.
App Control
Download the "GVM LED" app. Switch the light to APP mode, enable Bluetooth and GPS on your smartphone, and connect to "BT_LED" within the app. The app allows for remote control of brightness, color temperature, and scene modes. You can also save custom light effects in "My Scenes".
Scene Modes
When controlled via the App, the light can simulate 20 different lighting effects, including: Lightning, Cop Car, Candle, TV, Bad Bulb, Party, Disco, Paparazzi, Explosion, Pulsing, Fire, Fireworks, Welding, CCT Loop, Hue Loop, Ambulance, Fire Engine, SOS, STROBE (CCT), and STROBE II (RGB).
