There are batteries to make regular appliances smart, and now there's a light socket to make any lightbulb a connected one. Oh and that socket has its own LED light ring, too. Socket comes with an app that lets users turn their lights on, adjust their brightness and power, and create a room ambiance. Read: its light ring changes colors. And because it syncs with Apple's HomeKit, Siri also works. Socket costs $79, not including bulbs. With so many lightbulb options on the market how can we choose?!
