Each year 1.6 million women and children die as a result of indoor air pollution, much of it from kerosene lamps. But for the 1.6 billion people across the world without electricity there has been little alternative. D.Light has provided that alternative thanks to a cheap, reliable solar lamp. Over 220,000 units have already been sold in over thirty countries via a network of rural entrepreneurs. As one of these entrepreneurs says, “this will do to kerosene what mobile phones did to letters”.
