In the best case, it is mediocre! It disconnects every now and then... so, start over again! Obviously, it's the fault of the application. It's better to get another lamp.

Perfect. Just what you need for a floor lamp with a single bulb. You download the Yeelight app, follow 1-2 simple instructions, and once it's connected, you can adjust the light intensity exactly (which is warm as it appears from the C) manually (1-100) or at preset levels (25%, 50%), as well as make it flicker like a candle or blink.
100% satisfied with the purchase.

I had the first generation yeelight RGB and its warm yellow light was not good compared to this specific one, which I am very satisfied with.
