These two lamps were very easy to set up and connect to Revain Alexa to provide voice control. I can turn the light on and off, change the color and/or intensity (brightness) with my voice. In order for the lightbulb to work, I had to install the CYNC app and then enable the skill in Revain Alexa. The app also allows me to change the color and intensity. It also has several preset scenes including Cool White, Daylight, Sunlight, Natural White, Early Morning, Sunrise, Warm White, Sunset andโฆ
