Quick Guide from the Manual
The GVM-1300D and GVM-1500D are professional photography lights featuring RGB and bi-color capabilities. Key operations include:
- Mode Switching: Press the composite knob to switch between CCT, HUE, SAT, and SC (Scene) modes.
- Master/Slave Control: Set one light to Master and others to Slave with the same channel (CH) to synchronize settings.
- APP Control: Use the GVM_LED app via Bluetooth to control brightness, color temperature, and scene effects.
Product Overview
The lights feature an aluminum alloy construction with an LED screen for displaying brightness, mode, channel, and battery status. They support dual power supply: DC input (15V/5A) or two lithium batteries.
Installation

- Mounting: Attach the light to the bracket by rotating the knob clockwise.
- Diffuser: Insert the diffuser from the side of the light panel.
- Angle Adjustment: Loosen the adjustment knobs on both sides of the U-bracket, set the desired angle, and tighten the knobs.
- Accessories: If using light control folding, align the mounting holes with the hinges and secure with screws.
Operation and Modes
The composite knob is the primary control interface:
- CCT Mode: Adjust color temperature from 3200K to 5600K.
- HUE Mode: Adjust light color from 0° to 360°.
- SAT Mode: Adjust color saturation from 0% to 100%.
- SC (Scene) Mode: Access 8 scene effects: Lightning, Police car, Candlelight, TV, Bad light bulb, Party, Disco, and Paparazzi.
APP Control and Multiple Units
To control via APP:
- Turn on the light and set it to APP mode.
- Enable Bluetooth and GPS on your smartphone.
- Open the GVM_LED app, search for "BT_LED", and connect.
- For multiple units, set the APP-connected light to the desired channel and set other lights to Slave mode on the same channel for synchronous control.
Safety and Maintenance
- Do not use in highly humid environments or expose to corrosive liquids.
- Ensure the light is placed firmly to prevent falling.
- Disconnect power and remove batteries if the light will not be used for an extended period.
- Use only the provided or manufacturer-approved power adapters.
Practical help
Common problems
Ensure the light is in APP mode, Bluetooth and GPS are enabled on your phone, and you have connected to the device named 'BT_LED' within the app.
Verify that both the Master and Slave lights are set to the same channel (CH) and that the Slave light is correctly set to 'Slave' mode.
Check if the light is in APP mode and controlled by the phone, or press the ON/OFF button again to ensure it is not in a standby state.
Check if the SAT (saturation) value is set to 0. Increase the SAT value to see the color effect.
Before use
- Verify the power adapter matches the required voltage (15V/5A) or use two fully charged lithium batteries.
- Ensure the U-bracket knobs are tightened securely.
- Check that the diffuser is properly inserted if soft light is required.
- Enable Bluetooth and GPS on your mobile device for APP control.
- Set the correct mode (Master/Slave/APP) before operation.
