Sonoff B02-BL-A60 WiFi LED smart bulb for E27 base can bring dimmable cold white / warm white light into your home. You may choose the cold or warm white light for different activities and mood. Bulb connects with its WiFi to eWeLink cloud via your home or office WiFi network directly and can be remotely turned on and off in eWeLink APP, available both for Android and iOS phones. Pairing is done in a few seconds via Bluetooth, much more easier than WiFi of the previous product version.

You can both adjust the color temperature for warm and cold light and change the brightness level for various occasions. The bulb has a unique smart LED technology to ensure it saves your electricity bills by 90%, compared to a traditional bulb.

Group control makes it easy to control the lighting of a whole area, and multiple lights can be controlled together in eWeLink app. The app also provides you scheduled ON/OFF features, and lights can be also controlled by creating smart home automations with eWeLink app's Smart Scene feature. For example, you may use a PIR motion sensor or a door/window open sensor to turn on the lights automatically.

As all other Sonoff products, it supports voice control to turn on/off, adjust the brightness and color temperature via Alexa and Google Assistant.

Its universal E27 base fits for most standard light fittings.

With this smart bulb, you can do more than remotely turn on and off using your smartphone and via your voice (connect with Alexa or Google Home), a typical feature that the automated schedule can make the bulb automatically turn on and off which helps to save energy and reduce your monthly electricity bill. The bulb is dimmable and you can cool it down or warm it up to set the mood you want in the room. Group control is designed to help control the specific lighting of one or more areas, saving much time on running them respectively.
