Professor Invents the Best New Light bulb in 30 Years

So far the main alternatives to the common bulb have been CFLs and LEDs. Soon, a fourth lighting option will be thrown into the mix. It's called the FIPEL, which is short for field-induced polymer electroluminescent technology. The new light source is made of several layers of very thin plastic. Each sheet is about 100,000 times thinner than the width of a human hair. The plastic is inserted between an aluminum electrode and a transparent conducting electrode. When a current is passed through the device, it stimulates the plastic to light up. It works like a microwave oven but instead of giving off heat, it gives off light. Dr. David Carroll, a professor of physics at Wake Forest University in North Carolina developed the new light source.
