Does the Shelly Duo Bulb E27 Gen3 change RGB colours?

No. It is a tunable-white bulb from 2700 to 6500 K — it adjusts colour temperature from warm to cool and brightness, but does not produce RGB colours. For colours, choose an RGBW model.

Does it need a Shelly hub to work?

No. The bulb has built-in Wi-Fi 2.4 GHz and Bluetooth 4.2, so it connects directly to the Shelly Smart Control app with no separate gateway or hub.

How bright is it and how much power does it use?

It delivers up to 806 lm while drawing just 8.5 W, with a 200° beam angle — enough for the main lighting of an average room.

Does it work on 5 GHz Wi-Fi?

No, the bulb works on the 2.4 GHz band only (802.11 b/g/n). Make sure your router broadcasts a 2.4 GHz network before setup.

Which voice assistants and platforms is it compatible with?

It works officially with Amazon Alexa, Google Home, Samsung SmartThings and Home Assistant, so you can switch it by voice or add it to scenes.

What happens after a power outage?

When power returns the bulb turns on by default. The power-on behaviour can later be changed in the Shelly Smart Control app.

About this product

The Shelly Duo Bulb E27 Gen3 is a smart LED bulb with an E27 base and tunable white across the full 2700-6500 K range, from warm evening light to cool daylight. At 806 lm and just 8.5 W with a 200° beam angle, it replaces an ordinary bulb in a living-room, bedroom or kitchen fixture and dims smoothly with no hub needed.<br><br>Dual Wi-Fi 2.4 GHz and Bluetooth 4.2 connectivity lets you add the bulb to the Shelly Smart Control app quickly and build schedules and MQTT automations. It works with Amazon Alexa, Google Home, Samsung SmartThings and Home Assistant, and after a power outage it turns back on by default.

Where it works

Use cases

Home

In a Chisinau apartment bedroom the bulb fades to warm 2700 K in the evening and rises to cool 6500 K in the morning for an easier wake-up.

Home

On the kitchen ceiling, cool white 6500 K and 806 lm give clear, shadow-free light for cooking, and you dial it warm in the evening.

Home

In a building hallway the bulb turns on by default after a brief outage, so the stairwell stays lit with no manual action.
