The Nokero solar light bulb isn't going to win any design beauty contests, but sometimes it's worth noting substance can be an awfully beautiful thing in itself. The Nokero's utilitarian form was designed not only to withstand rain, wind and sun, but the 4 solar panels all around the standard bulb sized light can charge the nickel metal hydride battery within, which in turn powers 5 LED lights that can be used for up to 4 hours when fully charged.
The Nokero Solar Light Bulb was designed with impoverished regions such as Africa and India in mind, where dependable and accessible electricity can be a rare occurrence (thus the rugged appearance); the bulb-shaped lights are especially notable because they can help offset the use of polluting and expensive kerosene lamps in areas where the population can live in relative darkness at night normally.
The Nokero Solar Light Bulb is available in single or bulk amounts, starting at $15 for one and dropping down to $10/unit when purchased in a 48 bulb case. Ordering information available at Nokero.
