Engadget reports Lite-On has developed a LED bulb with integrated batteries, so you can use the bulb as a flashlight. The Lite-On Mobile Lamp LED bulbs are expected to come out sometime next year.
. 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.
