Liteon's 'Action Power Ball' LED bulb works even when the power is out
We hate to break it to you, but those LED light bulbs that are shaped like traditional light bulbs? It's all a lie. 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. To switch the bulb on or off you simply touch the copper part while something conductive makes contact with the metal part on the bottom, which could be a lamp socket or just a finger, as shown in the brief video after the break. The bulbs are due to be out sometime next year and should be hugely popular in areas with unreliable power -- or with an abnormally high rate of magicians per-capita.
