The old light bulb is about to go next-gen on us thanks to Bluetooth 4.0 to the mix. The Bluetooth Bulb lets you pair your phone with one or more lights in your home, and you can control them via an app. Pretty fancy huh?
You can do all of the usual stuff, like switch them on, off, change the brightness, set a timer, and a special RGB bulb even lets you change the color ambiance. No need to worry about the cost and waste either. Every part is replaceable.
So if you are looking for a light control system with no extra parts involved, this is a great solution. It is just a patented prototype right now, but they hope to go into mass production as soon as possible.
