The Shelly Duo Bulb E27 Gen3 is a dimmable LED bulb from the manufacturer, featuring adjustable white color temperature (2700K–6500K), Wi-Fi, and Bluetooth connectivity. It can be screwed into a standard E27 socket, making it easy to replace any existing bulb while instantly adding smart functionality to your lighting. It is ideal for home use, offices, or small commercial environments where flexible control of brightness and color temperature is required, either via an app or automation.
One of the key advantages of the bulb is that it works without a hub, connecting directly via Wi-Fi, but it can also be controlled via Bluetooth using Shelly BLU wireless switches or remotes. As part of the Shelly ecosystem, it offers advanced automation features, including scheduling, scenes, and even custom script-based operation. Thanks to the built-in web interface, it can also be fully configured locally.
The Gen3 version adds further benefits, as it can function as a Wi-Fi range extender and a BLE gateway, making it not just a lighting device but an active part of your smart home network. With energy monitoring, event logging, and advanced APIs, the product integrates especially well into advanced or DIY-based systems.
