Not too bright
Pairs with Alexa, easy to install and upload to the Alexa app. The color changing feature works well. Not very bright.

Good prices for Bluetooth smart bulbs
If you use updated Alexa, you need Bluetooth smart bulb.

Robert H. –
Good bulbs if you can standardize
These are very similar to other LED bulbs out there, except they are not readily available to the hub apps – you have to use the company’s own app and then connect it to your hub. Once you do it it isn’t that big of a deal. It would be annoying to have to troubleshoot multiple apps so if you are replacing the majority with these then it works better. Other than that, the bulbs are easy to connect and change the color/depth/warmth/brightness via the commands. For the price these are great entry level smartbulbs.

Great smartbulbs!
I love smart home technology. When I was a kid I dreamed of voice-controlled lights and gadgets, especially when it was late and I forgot to turn off a light. Once this tech hit the mainstream I adoped it. I’m spoiled now, and when I’m visiting places with physical switches I find myself confused. I didn’t have my whole house outfitted with smart bulbs but that’s my goal so I’ve been stocking up on bulbs. When I saw this listing I had to try them.They arrived in a nice box and contained all four bulbs.Setup wasn’t too difficult. Download the app, screw in the bulb, follow the instructions. They all paired on the first try.These are nice bulbs! They linked to our Alexa right away and I’ve been able to control them through our Alexa dots. I don’t mess with the color adjustment much but I really like the warm white lights these offer. They’re responsive, and when I flip the switch off and on they don’t lose their programming (though I haven’t left them powered off for any duration).Overall I’m happy with these bulbs. They pair quickly to the app, respond quickly to commands, and have the option for warm white lights.

Doesn’t work with Alexa; Amazon doesn’t care about false claims
Product was not compatible with Alexa. There are issues with the Skill. I called technical support and the person who called me back had no idea what they were talking about. I also called Alexa support, and they were no help and couldn’t even recommend another bulb that they were sure worked with their skills. We returned the items and found a workaround for our previously bricked Sengled bulbs.
