LED's and OLED's are like tiny computer chips that give off light. Incondescent lights are inofficient. 95% is wasted. LED's are 20-50% efficient. They use a lot of less energy. LED's could cut every use in half. We use color LED's for cell phones, street lights, and flashlights. Poor people around the world can use LED's without electricity. OLED's can be made at room temperature. LED's need high temperatures. White LED's are to expensive to make!!!!
