You always hear about how you should change to compact fluorescent lightbulbs and turn out the lights when you leave the room; with something like Motionbulb you can have both at the same time. A slick motion sensor is embedded in the bulb’s housing, turning itself on when it senses motion within 25 feet, and switching off when you leave the room
