Summary


This article I am reading is mostly about light, power, and energy. It was also
Talking about led’s and oled’s. Oled’s and Led’s are like tiny computer chips
That give off light. Led’s and oled’s are better than incandescent lights, and the
Reason for that is because incandescent lights are inefficient 5% goes to light,
95% is wasted led’s are 20 – 50% efficient, led’s help us because it could
Cut energy use in half we use colors led’s for cell phones, street lights, bridges, and flash lights.
