After I finally managed to connect all three bulbs I bought (several unsuccessful attempts later), I made the mistake of turning the power off. This resulted in a loss of connection and forced me to repeat the setup over and over again. Unfortunately, now only two lights are lit, and the other one just doesn't light up anymore. The brightness is mediocre and the color temperature cannot be adjusted in normal lighting conditions (warm color). Color mode also does not have the same level of brightness as normal mode. The user interface is fine though, navigating the color picker was easy. Scenes don't make any sense in the UI, they're just preset colors and some color cycles (the speed can't be changed). I think in the future I will look for another bulb supplier.
