Shelly Duo Bulb E27 Gen3

What it’s for: a smart E27 bulb with tunable white (CCT). The Shelly Duo Bulb E27 Gen3 screws into any standard E27 lamp holder and gives you dimmable white light tunable from a cosy 2700 K warm white to a crisp 6500 K daylight — warm for evenings, cool for working. Control it from the wall switch as normal, from the app, by voice, or pair it directly with a Shelly BLU remote or button.

Being a Gen3 device it also earns its keep in your network: enable the Wi-Fi range extender and it retransmits your Wi-Fi for other Shelly devices, or use it as a BLE gateway bridging Shelly BLU sensors into your system. Sunrise/sunset routines, weekly and advanced schedules, and smooth transition dimming are all built in.
