Find The Latest In Lighting Fixtures

Times change, and so do offerings in light fixtures. Not only will some styles change, so does technology, so as to be able to provide the most innovative and energy-efficient home lighting and other types of lighting fixtures.

As we all know, energy bills are only the rise. A capital investment today in a more efficient fixture today can pay for itself in your energy bills in perhaps a matter of months. Plus, of course, energy efficiency is a first step we all can take in terms of reducing our carbon footprints.

The Farreys website, available through the links presented here, allow to quick search through a variety of offerings and compare products side by side before purchase. In addition to lighting, Farreys carries ceiling fans and other products that can also make an impact on your household energy costs.

In terms of also saving money, check out various offerings for free shipping costs.

Researchers Develop Darkest Manmade Material

Researchers at Rensselaer Polytechnic Institute and Rice University have created the darkest material ever made by man.

The material, a thin coating comprised of low-density arrays of loosely vertically aligned carbon nanotubes, absorbs more than 99.9 percent of light and one day could be used to boost the effectiveness and efficiency of solar energy conversion, infrared sensors, and other devices. The researchers who developed the material have applied for a Guinness World Record for their efforts.

“It is a fascinating technology, and this discovery will allow us to increase the absorption efficiency of light as well as the overall radiation-to-electricity efficiency of solar energy conservation,” says Shawn-Yu Lin, professor of physics at Rensselaer and a member of the university’s Future Chips Constellation, who led the research project. “The key to this discovery was finding how to create a long, extremely porous vertically-aligned carbon nanotube array with certain surface randomness, therefore minimizing reflection and maximizing absorption simultaneously.”

The research results were published in the journal Nano Letters.

All materials, from paper to water, air, or plastic, reflect some amount of light. Scientists have long envisioned an ideal black material that absorbs all the colors of light while reflecting no light. So far they have been unsuccessful in engineering a material with a total reflectance of zero.

The total reflectance of conventional black paint, for example, is between 5 and 10 percent. The darkest manmade material, prior to the discovery by Lin’s group, boasted a total reflectance of 0.16 percent to 0.18 percent.
