3. Setup Guide
- Install the Bulb: Carefully screw the Brightech Smart LED Light Bulb into any standard E26 medium base lamp or fixture. Ensure the power is off before installation.
- Download the App: Search for and download the recommended smart home application (e.g., Tuya Smart or a compatible app) from your device's app store (available for Android and iOS).
- Register/Log In: Open the app and follow the on-screen instructions to create an account or log in if you already have one.
- Connect to Power: Turn on the power to the lamp/fixture where the bulb is installed. The bulb should begin to blink, indicating it is in pairing mode. If it does not blink, turn the power off and on quickly 3-5 times until it starts blinking.
- Add Device: In the app, tap the '+' icon or 'Add Device' to begin the pairing process. Select 'Lighting' or 'Light Source' and then 'Light Bulb (Wi-Fi)'.

- Pairing: Follow the app's instructions to complete the pairing. This usually involves confirming the bulb is blinking rapidly. Once connected, the bulb will stop blinking and may glow steadily.
- Rename Device: After successful pairing, you can rename the bulb to something easily recognizable (e.g., 'Living Room Lamp', 'Bedroom Light').
- Integrate with Voice Assistants (Optional): To use with Alexa or Google Home, link your smart home app account within the Alexa or Google Home app. Follow their respective instructions for adding new smart devices.
