Jim G: Bought one, liked it so much, bought 4 more

My first smart item was a Philips Hue smart bulb. It wasn t bright enough for me so I searched Amazon for a dimmable, color changing smart bulb which would give me lumens equivalent to at least 100 watts. I looked at a couple of different options.I went with 3Stone based on customer reviews and 3Stone s responses to customers questions. I wish the bulbs were brighter in color modes but 3Stone admits that in response to questions. The bulbs are easy to bring online using the Smart Life app. Once connected to Smart Life, Alexa discovered them easily. I have three bulbs in my bathroom. They can be controlled as a group on individually. 100W equivalent makes it easy for those of us who are math challenged. If I want a 60W bulb I can simle say, Alexa, change bulb to 60 . Individual smart bulbs are cheaper than installing a smart light switch and probably give you more control options. I just wish the color modes were a bit brighter and I wish the app would cycle the color modes. 3Stone, I ll be buying another 4 pack soon.
