Say goodbye to that annoying buzz created by overhead fluorescent light bulbs in your office or residence hall. Wake Forest scientists have used nanotechnology to develop a flicker-free, shatterproof alternative for large-scale lighting.
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
NXP Semiconductors has developed an innovative, sustainable and highly efficient solar-powered street lighting solution, together with Philips Lighting. The groundbreaking Solar Gen2 solution, demonstrated by NXP at CES 2012, could have a major impact on energy consumption in urban areas at night. By charging street lamps during daylight hours, the new solar-powered solution from Philips Lighting and NXP can supplement the capacity of the conventional electricity grid, saving money and reducing CO2 emissions. http://www.nxp.com/news/press-releases/2012/01/nxp-demonstrates-groundbreakin…
The key to the breakthrough lies in the combination of new High Brightness LEDs and unique patented optics from Philips Lighting, together with NXP’s MPT61x range of configurable ICs for Maximum Power Point Tracking (MPPT), which can deliver 98% power conversion efficiency in solar photovoltaic (PV) cells.

The Energy Smart LED bulb does not contain any hazardous substances and will fit into any traditional bulb socket.
GE Fast Forwards to Future of LED Lighting
Unveils unique LED bulb designed to distribute light like an incandescent bulb, last 17 years
About $50 for this energy smart LED bulb. If you only need one light bulb would you pay $50 for it, knowing it lasts ‘forever’?
