Shelly Duo RGBW (for E27 socket) is an energy-efficient smart RGBW bulb from Shelly with both color light and dimmable white light, offering also light temperature setting feature for white light. Equipped with WiFi, it can be controlled, scheduled from smartphone app or a web browser, from cloud or local network.

Connect Shelly Duo directly to your Wi-Fi at home or office, play with the light and choose the appropriate color, lightness and light temperature to match the light to your mood and activities. With Shelly Duo it's easy to set stronger cold light for work and reading, warmer light for a family dinner and color or warm small light for a romantic evening.

Presence simulation is also supported, just as in case of other Shelly products. While you are not at home, with the 24h timer for each day of the week you can preset the exact time when the lights go ON and OFF.

It's a Plug&Play solution, just remove the old bulb and screw in your new Shelly smart bulb in the socket. Pair with your smart phone with a few clicks, and ready to use. Choose your brightness and light temperature in the app or in the browser, and enjoy!

Just as it name suggests, it has two major features:

  • white light is dimmable
  • white light's temperature (cold vs warm white) can be set.
  • +1: colored light can be also set.

Of course, you can turn on and off the light with your traditional switch just as in case of a traditional bulb.

Automatically follow the sun and control your light accordingly. Set your Shelly DUO Bulbs to turn on/off based on the sunrise and sunset hours.

No more stressful bright light during the dark early hours of the morning. Set your custom schedule and choose soft and low light while it is still dark outside when you need to turn on the lights early in the morning.
