They worked... For a year and a half.
I bought 9 tp-link smart bulbs on july 9th, 2017.I bought 2 lb130 (multi color), 6 lb120 (white/adjustable warmth), and 1 lb110 (warm white).It is now october 13, 2018.The lb130s and lb110 are still working perfectly.The lb120 on the other hand.. I've had four go bad. The first one went bad in january 2018, the second one went bad in march 2018, the third in august 2018, and the 4th in september 2018.At first they just say they're disconnected. Flipping the light off and back on by the power source fixed it for a few weeks. Temporarily. Then they would just stop working. They'd stop responding entirely. 2 stopped working while in the on position, so the lights would stay on and i'd have no control over them. The other 2 stopped working while in the off position, so they'd stay off (the leds still worked, because turning them off an on 5 times would make them flash to do a factory reset, but then would continue not working).I am displeased with the performance of these tp link smart bulbs, and probably won't be buying any more. I'll be replacing them with a different brand of smart bulbs.
