2. Setup Instructions
To utilize the full smart features of your LGIDTECH FUT103 LED Spotlight, you must first set up the MiBoxer 2.4G Gateway (WL-Box1 or similar compatible gateway, sold separately) and pair it with the control application.
2.1. Gateway and App Pairing
- Step 1: Power on the Gateway
Connect the MiBoxer gateway to a power source using the provided USB cable (adapter excluded, compatible with phone adapters). Long press the 'SET' key on the gateway for 3 seconds until the 'SYS' indicator blinks quickly. - Step 2: Open the Control Application and Add Device
Open the MiBoxer or Tuya Smart application on your smartphone. Tap 'Add Device' or the '+' icon to begin searching for nearby devices. Ensure your phone's Bluetooth is enabled. Select 'Light Source (BLE+Wi-Fi)' from the lighting category. - Step 3: Pair with Wi-Fi
Confirm the gateway's indicator light is blinking rapidly. Enter your 2.4 GHz Wi-Fi network password (5GHz networks are not supported). The application will then search for and add the gateway. Once successfully added, the 'LINK' indicator on the gateway will turn green. - Step 4: Linking Lamps or Other Devices
From the gateway control interface in the app, navigate to the 'Set' tab and select 'Link/Unlink'. Choose the desired zone (e.g., Zone 1, Zone 2, etc., or ALL). Power off the LED lamp, then reload power after 10 seconds. Within 3 seconds of the lamp turning on, press the 'Link' button in the app. The lamp will flash 3 times slowly to indicate successful linking. If linking fails, repeat the steps.

3. Operating Instructions
Once your LGIDTECH FUT103 LED Spotlight is linked to the gateway and control application, you can manage its various lighting features.
3.1. Color Changing (RGB)
Access the 'Color' tab within the application. You can select from 16 million colors to create different moods and ambiances. Simply tap or drag your finger across the color wheel to choose your desired hue.
3.2. Color Temperature Adjustment (CCT)
In the 'White' tab of the application, you can adjust the color temperature from 2700K (warm white, suitable for relaxation) to 6500K (cool white, ideal for working or focused tasks).
3.3. Dimming
Adjust the brightness level of the light using the dimmer slider available in both 'White' and 'Color' modes within the application.
3.4. Memory Function
The bulb features a memory function, retaining the last color, brightness, and mode settings even after being turned off and on again.
3.5. Remote Control Compatibility
The FUT103 bulb is compatible with various MiBoxer remote controls (sold separately) for direct control without the app, including:
- 4-Zone Remote FUT092

3.6. Voice Control
When connected via the WL-Box1 Gateway, the bulb can be controlled using voice commands through compatible smart home assistants like Amazon Alexa and Google Home Assistant.
4. Maintenance
To ensure the longevity and optimal performance of your LED spotlight, follow these general maintenance guidelines:
- Cleaning: Ensure the bulb is powered off and cool before cleaning. Use a soft, dry cloth to gently wipe the surface. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the bulb.
- Environment: This product is designed for indoor use only. Avoid exposure to extreme temperatures, high humidity, or direct water contact.
- Installation: Ensure the bulb is securely screwed into a compatible GU10 base. Do not overtighten.
- Power: Always ensure the voltage is within the specified range of AC 100-240V / 50-60Hz.
5. Troubleshooting
If you encounter issues with your LGIDTECH FUT103 LED Spotlight, refer to the following common solutions:
- Bulb not responding to smartphone app:
Confirm that you have a MiBoxer 2.4G Gateway (hub) connected and properly paired. This bulb cannot be controlled directly by a smartphone without the gateway. Ensure the gateway is powered on and its 'LINK' indicator is green. - Linking failed (light does not flash slowly):
If the light does not flash slowly after power cycling and pressing 'Link' in the app, repeat the linking steps carefully. Ensure the power is turned off for at least 10 seconds before turning it back on and attempting to link within 3 seconds. The light may already be linked to a different code if it does not respond. - Incorrect color or brightness:
Check the settings in your control application. Ensure you are in the correct mode (White or Color) and adjust the sliders accordingly. - Bulb not turning on:
Verify that the bulb is securely installed in the GU10 base and that the power supply is active. Check the voltage to ensure it is within the AC 100-240V range.
