Setup
1. Installation
- Power Off: Before installation, ensure the power supply to the light fixture is turned off at the main switch to prevent electrical shock.
- Insert Bulb: Carefully insert the GU10 base of the LED spotlight bulb into the compatible GU10 socket. Twist gently until it is securely seated.
- Power On: Restore power to the light fixture. The bulb should illuminate in its default setting.
Caution: Ensure the voltage is within AC 100-240V, 50-60Hz. Do not install in wet locations or enclosed fixtures that restrict airflow, as this may shorten the bulb's lifespan.
2. Connecting to Control Devices
The FUT103 bulb requires a compatible remote control or a gateway for smart control features. It cannot be controlled directly by a smartphone without a gateway.
- Remote Control: This bulb is compatible with Mi-Light/Miboxer remotes such as FUT092, FUT089, B4, and B8. These remotes are sold separately. Refer to the remote control's manual for pairing instructions.
- Smartphone/Voice Control (via Gateway): For smartphone app control (MiBoxer APP) and voice control via Alexa or Google Home Assistant, an additional WL-Box1 Gateway (sold separately, ASIN: B01N7C3HXQ) is required.
- Connect the WL-Box1 Gateway to your home Wi-Fi network according to its instruction manual.
- Open the MiBoxer APP on your smartphone.
- Follow the in-app instructions to add and pair your FUT103 bulbs with the gateway.
- Once paired with the gateway, you can link the MiBoxer APP to Alexa or Google Home Assistant for voice control.
Operating Instructions
Once your FUT103 bulb is installed and paired with a compatible control device (remote or gateway), you can access its various lighting functions.
- Power On/Off: Use the designated power button on your remote or the app interface to turn the bulb on or off.
- Brightness Adjustment: Adjust the light intensity using the brightness controls on your remote or within the MiBoxer app.
- Color Changing (RGB): Select from 16 million RGB colors. On a remote, this is typically done via a color wheel or dedicated color buttons. In the app, a color picker interface is usually available.
- Color Temperature Adjustment (CCT): Change the white light from warm white (2700K) to cool white (6500K). This is often controlled by a slider or dedicated buttons for "WW" (Warm White) and "CW" (Cool White) on remotes, or a CCT slider in the app.
- Mode Selection: Some remotes and the app may offer pre-programmed dynamic lighting modes (e.g., flash, fade, jump).
- Memory Function: The bulb retains its last used color, brightness, and mode settings when turned off and on again, ensuring consistent lighting without needing to reconfigure.
Maintenance
- Cleaning: Ensure the bulb is off and cool before cleaning. Wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Replacement: When replacing the bulb, ensure the power is off. Allow the bulb to cool completely before handling. Unscrew the old bulb and screw in the new GU10 bulb.
- Storage: If storing the bulbs, keep them in their original packaging in a cool, dry place away from direct sunlight.
Troubleshooting
- Bulb does not light up:
- Check if the power supply to the fixture is on.
- Ensure the bulb is correctly installed and securely twisted into the GU10 socket.
- Verify that the voltage matches the bulb's requirements (AC100-240V).
- Test the bulb in another working fixture if possible.
- Bulb is not responding to remote/app control:
- Ensure the bulb is powered on.
