I bought one Philips light. Nothing special, no colors, nothing. Just a white lamp. But wanted to dim it. That requires an app from China! The good news is that I wasted a half an hour of my life trying to get the app to recognize a lamp blinking three feet away. Never paired to the light bulb. Tried automatic (twice) and tried manual (several times). If I could rate it lower I would. Bought a dimmer cord on Amazon. It worked first time and not dependent upon some software company in China knowing where I am and what I'm doing with the light bulb in my dining room!
