bottle lights

Liter of Light - a company in the Philippines - has recycled plastic bottles by turning them into lights that do not need electricity. The company had successfully installed about 3,50,000 bottle lights in more than 15 countries. The lights were made out of plastic bottles, water, galvanized steel, and bleach. These easy to maintain bottle lights produce the same light as a 50W incandescent bulb and could be installed anywhere.
