The Link2Home Wi-Fi LED Filament Dimmable Bulb combines a beautiful rustic golden lamp with modern control. Move across the white light spectrum from an ultra-warm 1,800K through to a cool 2,700K. You can also dim the light via the Link2Home Pro app (Free). Control your home atmosphere via app control or voice. Using the Link2Home Pro app, you can set up precise timers that can be customised by days of the week. Set up countdown timers too. You can group multiple lights together to control one room, one house, or control each light individually. Fully integrated with Amazon Alexa and Google Assistant. Just ask your smart speaker to control your light device or group by saying 'Alexa turn on the hallway' or 'Hey Google! Turn on the living room lamp'.
