A new study from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute found that office workers who receive a robust dose of circadian-effective light in the morning, from electric lighting or daylight, experience better sleep and lower levels of depression and stress, than those who spend their mornings in dim or low light levels.

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy The DOE SSL team was out in full force at LIGHTFAIR, where we offered a wide range of educational sessions in our booth, which was jam-packed with people seeking more information about [...]

Shirley Coyle, President of Cree Canada, recently contributed her thoughts to Lighting Design & Application in response to a request to chime in on the American Medical Association’s recent guidelines for LED outdoor lighting. She points out that basing recommendations on correlated color temperature (CCT) is flawed: On the issue of safety, the most obvious [...]

Eaton has announced the winners of the 40th Annual SOURCE Awards lighting design competition. The winners were recognized on Monday, May 8 at LIGHTFAIR International 2017 in Philadelphia, Pennsylvania. Six professional awards and seven student awards were presented. The annual competition, which began in 1977, focuses on furthering the understanding, knowledge and function of lighting [...]

Below is my contribution to the April issue of tED Magazine. Reprinted with permission. Outdoor lighting has proven a key market for LED sources due to their durability, directionality, efficiency, longevity, color and optical control. While metal halide and high-pressure sodium remain predominant in the installed outdoor lighting base, LED has captured a majority of [...]

Seniors represent the fastest-growing segment of the population with over 40 million Americans over 65 (U.S. Census Bureau, The Older Population. 2010), with over 10,000 Baby Boomers turning 65 every day. The over-40 population represents approximately 89 million people and of those, 63% have vision problems (National Eye Institute of the National Institutes of Health [...]

My contributions to the January issue of ELECTRICAL CONTRACTOR included a roundtable interview with noted experts who speculated on the future of lighting as shaped by several trends. Major lighting trends—including LED, intelligent lighting controls, the industrial Internet of Things (IIoT), power over ethernet (PoE), energy codes, and light and health—are creating new opportunities and [...]
