If you plan on using these bulbs with Alexa, look elsewhere. Response is too slow. I tell Alexa to turn on the light. Writes "the device is not responding" and after 5 seconds the light comes on. Too much delay that other smart bulbs don't have. Even unnamed brands are more responsive. I have found that Kasa lamps are the most reliable and have an instant response time. I will be returning these C by GE (Cync) smart lightbulbs.
