These are the new version of the Xiaomi Yeelight bulbs which were released this year with a few new features. They're now 10W (was 9W), have 800 lumens (was 600) and have native Apple HomeKit support in the second half of 2018.
Like the previous version they have a massive range of colour combinations and equipped with WiFi that allows you to control them through the Yeelight and Mi Home app. They can also be integrated with Google Assistant, Aamazon Alexa and other smart home systems via IFTTT. They're great for setting mood lighting, flowing lights for that romantic night or beat in sync with music.
