• Rotate Control mode: Lighting effect adjusted by the dimming knob.
• Slave Control mode: Channels adjusted by ▲/▼ buttons. Synchronized and controlled with the master if channels match.
• Master Control mode: Lighting effect and channels adjusted by the dimming knob. Slave machines with the same channels are adjusted synchronously.
• APP Control mode: Lighting effect adjusted by the APP.

The multifunctional knob switches between color temperature, hue, and saturation:

• CCT mode: Adjusts color temperature from 3200K to 5600K.
• HUE mode: Adjusts hue from 0° to 360°.
• SAT mode: Adjusts saturation from 0% to 100%.

Adjust Brightness (BRG)

On-line Control (Joint Control)

• To control multiple lights: Set one as Master mode, others as Slave mode. Ensure master and slave channels match for synchronous control.
• To control via APP: Set one light to APP mode and connect to the mobile app. Set other lights to Slave mode with matching channels. The APP can then control the connected light and synchronously control slave lights.

APP Control

Switch the light to App mode, connect its Bluetooth to your phone. Use the App to control brightness, color temperature, color, saturation, scene type, channel, and power on/off.

The APP can simulate 20 different scene lights: 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).

If there are controlled slave machines, they can also be controlled through the App.

App Control

1. Scan the QR code on the back of the manual to download the APP.
2. Turn on the light, switch to APP mode. Ensure phone Bluetooth and APP permissions are enabled (Android requires GPS and positioning permission). Open the "GVM LED" application, navigate to the Bluetooth search interface (Figure 1). Find "BT_LED", click connect. Upon successful connection, the APP control interface (Figure 2/3/4) opens, allowing control of the connected light. If a slave light is present, the APP will synchronously control it if its channel matches the connected APP mode machine. Note: Do not pair Bluetooth via the system's Bluetooth page; open the APP directly for pairing.
3. Save up to 6 custom light effects in "My Scenes". After setting parameters, click the [disk-icon] in the right corner, select "Save Current Scenes", and click "OK". The effect will be found in "My Scenes". (Figure 5)
