The Wall Street Journal also reported today that light is increasingly being used to diagnose and monitor diseases such as diabetes, highly desirable because it is non-invasive. Light is already used for eye surgery, dental work, cosmetic skin work, combating SAD, hair transplantation and other uses. Get the story here.

A Frost & Sullivan research report, titled European Energy Efficient Lighting Markets, provides an in-depth analysis of the competitive landscape while detailing key market and geographic trends in the European energy-efficient lighting market, focusing on CFLs, LEDs and halogen lamps in the commercial, residential, public and industrial sectors.

NOTE: The bad link at the bottom has been fixed. The Lighting Research Center‘s DELTA program recently field tested photovoltaic-powered LED luminaires installed at three public, outdoor sites in the Catskill Mountains region of upstate New York. The luminaires were prototypes designed by Sullivan Renaissance, Philips Hadco and SolarOne Solutions. Click here to learn the [...]

LED technology continues to rapidly mature and is pursued as a street lighting alternative to traditional lamp sources categorized as HID lamps such as high pressure sodium. In order to quantify the performance of new LED street lighting options, lighting specifiers must compare the claimed benefits of LED fixtures, including long life, reduced maintenance, and [...]

The California Lighting Technology Center (CLTC) recently demonstrated Philips Day-Brite NiteBrites HID wall packs at California State University, Chico. The demonstration included replacing 13 150W high pressure sodium wall packs and one 70W HPS tall wall pack with 14 new bi-level HID fixtures at Shasta and Lassen halls. The retrofit increased light levels of the [...]

The Alliance for Solid-State Illumination and Technologies (ASSIST) recently published a technical paper that quantitatively evaluates the impact that outdoor lighting has on the human circadian system. A growing interest in the role that light plays on human health, combined with the increasing use of white outdoor lighting with high correlated color temperatures and a [...]

The Department of Energy recently announced that it has completed Round 10 of product testing through its CALiPER program. A Summary Report containing the results from the new testing is now available for download on the DOE SSL website here. Round 10 of product testing covered four main categories: parking structure luminaires, outdoor wallpack luminaires, [...]

U.S. Department of Agriculture scientists recently stated the conclusions of a new study that found that supermarket lighting can help keep spinach fresh and producing new vitamins. Sorry, kids, it doesn’t make it taste any better. Get the story here.

A recent survey of lighting designers and specifiers by the National Lighting Product Information Program showed that for retail applications, light source color properties are considered more important than any other light source criterion, including energy efficiency. To define light source color properties, the lighting industry predominantly relies on two metrics, correlated color temperature (CCT), [...]
