I've got two now. One is multicolor and one is soft white, but both are adjustable as far as brightness level. When Alexa works with them, it is cool. She doesn't always work with them though. I'm not sure if the fault is with Amazon or with TP-Link and the code they created to connect their bulbs to Alexa. Probably the latter. But there are days that Alexa will not be able to control the bulbs, but most days she can. However, the scenes have never worked. Again, I think this is mostly due to TP-Link and not Amazon, but I cannot be certain of that. Mostly I use my iPhone/iPad to control them, especially the multicolored one since I was never able to control the color hue via Alexa.
