I don’t know how I missed this one. — the Nokera solar-powered light bulb.  Designed to replace kerosene and other fuel-powered lanterns in developing countries that don’t have a power grid and electricity.  A day’s-worth of charging in the sun will produce 2 to 4 hours of light from the bulb’s 5 LED’s.

Purported to be durable, rainproof and shatter-resistant.  Many of its parts are replaceable.  Bummers: price and battery life.  A single bulb costs $15 and the replaceable NiMH battery has about a 2 year life span with daily use.  Marketed primarily to large, aid organizations.
