eufy has discounted the Lumos Smart Bulb, it's very popular smart bulb that is already pretty cheap at $18.99, but now it's even cheaper at $12.99 each. This is a great deal for this bulb, considering most other smart light bulbs that are tunable white, are closer to $30. Makes it a great way to make your lights in your home smart, without spending a fortune.
The Lumos Smart Bulb from eufy (a division of Anker), is a typical-sized smart bulb - the A19 size - and will work with virtually any light socket or lamp in your home. It's important to note that these are not safe for using outdoors. Using the eufy app, which is available for Android and iOS, you'll be able to turn on and off the lights when you wish. You can also set a schedule so that it turns on at a specific time of the day, all by itself. And of course you can also adjust the temperature of the light. So if you want lights that are more white than yellow, you can do that with the app, which is pretty nice to see. Finally, this light bulb is also compatible with Amazon Alexa and Google Assistant, so you can use your voice to control these light bulbs which is definitely a nice feature to have.
