plenty of those ritzy LED light bulbs to choose from, but how's about using the ultimate light source to create... even more light! That's exactly what Nokero is setting out to accomplish with its N100, which is being christened the "world's first" solar light bulb. Designed specifically for use in developing nations where continual electricity is a mere pipe dream, this bulb is housed in an ultra-rugged, rainproof enclosure that can provide around four hours of light when fully charged; if you leave it in the sun all day, it'll harness enough juice to provide illumination for around two hours. The unit itself is constructed from impact resistant plastic and includes a foursome of solar panels, five LEDs and a replaceable, nickel metal hydride battery that's said to last two years. The company informed us that these will run you around $15 if purchased one at a time, though the goal is to sell 'em in bulk for around $6 apiece and have them delivered to rural parts of India, Africa and possibly District 9. Go on and get schooled by heading past the break and clicking play.
