A more efficient efficient plastic lightbulb is being developed.
A more efficient plastic light bulb is set to start production next year.
The plastic bulbs are the invention of Doctor David Carroll, a Wake Forest University professor of physics. His bulbs use three layers of white emitting polymer and nanomaterials that light up as an electric current flows through.
He says the light spectrum of common fluorescent bulbs is unnatural, telling the BBC: "They have a bluish, harsh tint to them, it is not really accommodating to the human eye; people complain of headaches and the reason is the spectral content of that light doesn't match the Sun.” He says “our device can match the solar spectrum perfectly.”
Another new light bulb that is designed to last for over 20 years is the light emitting diode, or LED light. LED lights for use at home can cost between 20 and 60 dollars a piece.
They use up to 90 percent less energy that incandescent bulbs but produce the same amount of light.
The LED bulbs will reportedly work for over 20 years based on approximately 3 hours of daily use
