LEDs are naturally pretty small things, and while there might be dozens scattered about inside a bulb there's still plenty of empty space in there meant only to make the things about the same size as a good ol' incandescent. Lite-On, however, has found something to make use of that space: batteries. The company's Mobile Lamp bulb can stay on for up to two hours even after the power is turned off, effectively turning it into a flashlight.
