Amazon is currently discounting single Philips Hue lights, dropping the price down to just $35. Now it's worth noting that if you live in California, they are priced at $39.99. That's still on sale, down from its regular $50 price tag, but not as great of a deal as the rest of the country.
Philips Hue is one of the more popular smart home ecosystems, which has a number of great lighting options available. These are for single bulbs, which means that the hub is not included. If you are looking to get started with Philips Hue, you're going to need to get the Hue Bridge. These will not work without it, since the bulbs themselves do not have WiFi, only when it is connected to the Hub.
These bulbs can do millions of different colors, which you can change from within the app. It is also compatible with Amazon Alexa and Google Assistant, so you can use your voice to control the bulbs if you wish. These are A19 sized bulbs, so they will work in most light sockets.
