The latest addition to the Philips Hue smart light system is a small black box that syncs a room full of lights with whatevers happening on your TV. Games, movies, streaming media, or anything else youre watching can pass through the box, which will perpetually adjust the color and brightness of your lights to match, creating a more immersive experience.
