To those living in developed countries, Sun King solar lights are pretty cool little gadgets. Once charged using a small solar panel (included) they provide a good source of light for up to 30 hours. Or they can be used to recharge up to two cell phones at a time. They could be a fun item to take on a camping trip or use during a power outage. 

Designing and distributing technically sophisticated yet durable solar lights has been a nifty accomplishment for Greenlight Planet, whose aim is to replace dangerous kerosene lamps. [Christian Science Monitor ]
