Perfect for rooms up to 10-12 m2. I hung two on a 15m2 room, because one seemed not enough, even a large version of the 550C. Although who cares. But now, at full power, the room is as bright as in an operating room)) The full functional potential is revealed, of course, only through applications (Yeelight, MiHome). The remote control is in principle convenient for quick actions and basic settings. I also installed Yeelight switch-buttons, switched the lamps to Flex-mode, now they are always online. But in working with the / Alice application, the functionality is greatly curtailed. In fact, there you can only turn on / off, change the brightness and color temperature of the main lighting. The backlight / night mode (moon) can no longer be turned on (Maybe in future versions of the application they will finish it.
