The Bluetooth Bulb is a prototype lightbulb that features Bluetooth 4.0 with a range of 50 meters. After you’ve screwed it into a socket, you can download an app and pair it with your smartphone, allowing you to control the bulb. You can turn it on and off, dim it, set a timer, or even change the color with a special RGB model. You can use your device to control a number of these next-generation bulbs, and multiple devices can be paired with each bulb. Check out the video below to see the bulbs in action:
