Product detailed description

💡 Create the perfect atmosphere for every moment

Shelly CCT Bulb E27 Gen3 is a bulb that combines tunable white, dimming and advanced automation features in one compact solution. Thanks to Wi-Fi and Bluetooth connectivity, the bulb easily integrates into any smart home. Set the right light for every moment. Enjoy adjustable white light, from warm and cozy to bright and cool. Create lighting schedules for months ahead, trigger automations and control everything remotely from your preferred platform.

It can be screwed into a standard E27 socket, allowing easy replacement of an existing bulb and instantly adding smart functionality to your lighting. It is ideal for home use, offices or small commercial spaces where flexible control of brightness and color temperature is needed, either through an app or automation.

One of the main advantages of this bulb is that it works without the need for a hub, connecting directly via Wi-Fi, but it can also be controlled via Bluetooth using a wireless switch or the Shelly BLU remote control. As part of the Shelly ecosystem, it offers advanced automation features, including scheduling, scenes, and even operation based on custom scripts. Thanks to the built-in web interface, it can be fully configured locally.

The Gen3 version adds further benefits, as it can act as a Wi-Fi range extender and a BLE gateway. This makes it not just a lighting device, but an active part of your smart home network. With energy consumption monitoring, event logging, and advanced APIs, the product integrates exceptionally well into advanced or even DIY systems.
