Light is not only a source of energy for plants but also an important signal which regulates many light-dependent growth processes allowing it to effectively adapt to its environment. Light is first detected by photoreceptors in the shoot of a plant. For more than three decades, scientists have been speculating whether roots are also able [...]

As part of current research sponsored by Southern California Edison, the California Lighting Technology Center (CLTC) is updating its Advanced Daylighting Lab to include dynamic fenestration and integration of electric lighting and HVAC systems. Activities are being conducted in collaboration with ready-to-integrate manufacturing partners so that new systems can more quickly and effectively transition to [...]

Lighting tailored to the needs of an individual can improve sleep and reduce depression and agitation in persons with Alzheimer’s disease, according to a recent study led by Dr. Mariana Figueiro, Light & Health Program Director at the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute in Troy, NY. The study, published in the April [...]

Linear or tubular LED lamps (TLEDs) typically draw about 60% of the power of linear fluorescents and have become a viable retrofit option. DOE’s CALiPER program has released a new Snapshot report on TLEDs that’s based on LED Lighting Facts data. Among the key findings: • TLEDs now comprise more than 50% of all lamps [...]

The U.S. Department of Energy has published the latest edition of its biannual report, Energy Savings Forecast of Solid-State Lighting in General Illumination Applications, which models the adoption of LEDs in the U.S. general-lighting market, along with associated energy savings, based on the full potential DOE has determined to be technically feasible over time. The [...]

I contributed this short article to the February 2016 issue of tED Magazine, published by the National Association of Electrical Distributors (NAED). Reprinted with permission. Manufacturer Zumtobel recently concluded a field study with Gerry Weber that showed an increase in sales based on a lighting solution optimized based on the personality type of the fashion [...]

According to a new report published by Allied Market Research titled, World Organic LED Market – Opportunities and Forecasts, 2014 – 2020, the world OLED market is estimated to generate revenue of $37.2 billion by 2020, registering a CAGR of 18.3% during the forecast period 2015 –2020. Enhanced picture quality, high energy efficiency, increasing demand [...]

In late 2014, the U.S. Department of Energy’s (DOE) Municipal Solid-State Street Lighting Consortium (MSSLC) published the results of a survey of entities across the United States that operate public street and area lighting.
 The survey was conducted in the latter half of 2013 to gain a better understanding of national energy consumption related to [...]

A brief article I wrote for tED Magazine. Reprinted with permission. In Value Metrics for Better Lighting (SPIE Press), Mark S. Rea, PhD, professor and director for the Lighting Research Center at Rensselaer Polytechnic Institute, proposes a new solution to an old problem in the lighting industry. The industry, he says, has traditionally focused on [...]
