This Motion detecting light bulb is the new and revolutionary light bulb that turns on automatically when you enter the room and turns off automatically when you leave. Built into the tip of the bulb is a small motion detector. The detector is only active if there isn’t enough ambient light (you can control this) and activates the bulb when it detects ‘temperature changes’. Once you leave its 25 foot-detecting-radius the bulb turns off within 10 seconds to 5 minutes, it just depends on your preference. Available now for $19. [GadgetReview]
