A
If you've got a reliable Internet connection, smart lights are a cheap way to make your home very cool. Here are four of them.
LIFX
The biggest feature: you don't need a separate hub to control your smart lights. They connect via Wi-Fi and you can stick the lights anywhere. The LEDS create up to 16 million colors and are programmable, so you can create custom lighting patterns through the smartphone app. You can also set up a lighting schedule and make changes with your voice through Amazon Alexa, Apple HomeKit, and Google Assistant. $70.
Sylvania
The Sylvania LED light strip(灯带) is Apple HomeKit-enabled, meaning you can change colors and settings with Apple's smart voice assistant Siri or through the app. The only feature Sylvania does not include -- one that LIFX does -- is the ability for the lights to automatically rotate(转换) through colors. With these lights, you can only adjust brightness and change colors. $39.
If you use an Android phone, make sure to get an Android version. It has the same functions but is also compatible
(兼容的) with Amazon Alexa or Google Assistant. $52.
Eve
The Eve LEDS can be extended with additional strips and reach up to 32.8 feet. The LEDS produce a full range of whites and colors and are compatible with Apple HomeKit -- therefore voice controlled with Siri. This setup requires no extra hub. The starter version is available for $80 and extension strips are available for $50.
Minger
Mingers Wi-Fi connected strips of LEDS are 16.4-feet-long and can be controlled via the Govee app on your smartphone or with Amazon Alexa. The company doesn't recommend connecting multiple strips. $29.
