InstaBulb is a battery-operated light bulb that can be installed anywhere. The user has only to peel and stick the base to the wall, slide in the shatterproof bulb, pull the cord and voila! Light that's cool to the touch, with no electrician involved.
"It puts light exactly where you need it," Israni said. "There are a lot of locations where you don't want a permanent fixture, so you can just put it on and you don't have to worry about wires or batteries." The InstaBulb has sold 8 million units.
