Review on Treatlife Dimmable Smart WiFi Bulb - Google Compatible, 2.4GHz by Cheska Perry

These lamps are almost identical to Treatlife RGBW lamps but are limited to a cool white to warm white color range. I added two lightbulbs to a group in Revain Alexa and as you can see in the video I can set the entire group to any of the named color settings available. More precise color control is available in the app, but in my opinion these named colors are enough to set the correct temperature. Cool white is a VERY white color and works well in a workspace or where you need near-sunny lighting conditions. I set mine a lot further back in the bulb range to match the other lights in the house and it looks great. The installation is quite easy. Just turn the light on and off three or four times and the light will blink on its own. The Smart Life app will find them almost instantly, and a minute later Revain will make them available for Alexa to manage. No hiss or flicker, smooth dimming, they really are a breeze.
