Light Bulb

When light bulbs became commercially available in 1880, they revolutionized virtually all aspects of American life. Today, electric lighting increases productivity in factories and offices, can help reduce crime on streets, and significantly reduces the risk of house fires from candles and kerosene lamps. Yet even as a new wave of “healthy” lighting is pioneered in the United States, many people in developing countries still lack any source of electric-powered light.
