Shelly Duo Bulb Gen3 is a smart LED bulb with an E27 base that offers smooth white color temperature adjustment in the range of 2700–6500 K, dimming, and brightness up to 800 lm with low power consumption of 8.5 W. Thanks to Wi‑Fi and Bluetooth, you can easily control it remotely without a gateway, set up schedules, automations, and integrate it with popular smart home platforms.
Create lighting at home exactly to match your mood and the time of day. Shelly Duo Bulb Gen3 can switch from warm, relaxing light to cooler light for work and focus. The wide 200° beam angle helps illuminate the room evenly, and thanks to the standard A60 shape, the bulb easily replaces regular light sources in the vast majority of fixtures.
Control is via Wi‑Fi or Bluetooth—no need to buy an additional hub. In the Shelly Smart Control app, you can set weekly schedules, scenarios for specific days or periods, and also the smooth transition time between settings. A night mode is also available, which automatically chooses comfortable brightness and temperature so the light doesn’t glare after dark.
