First Photograph of Light as a Particle and a Wave

Quantum mechanics tells us that light behaves as both a particle and a wave, and scientists have tried to observe both aspects at the same time. In 2015, scientists at the Federal Institute of Technology in Lausanne in Switzerland achieved a snapshot capturing both properties. Learn more here.

Flicker May Play Future Role in Fight Against Alzheimer’s

Researchers have discovered that pulsing light reduces toxic proteins associated with Alzheimer’s disease in laboratory mice, raising hopes of future application to humans. Click here to learn more.

Study: LED Lighting Can Preserve Natural Taste of Milk

New LED lights that are being installed in milk display cases across the country do more than just reduce energy bills — they also help milk taste better, Virginia Tech researchers have found. The exposure to certain light changes the flavor profile of milk. Milk fresh from the dairy should taste sweet and rich but […]

Color Study Challenges CRI

Below is one of my contributions to the January issue of tED Magazine, the official publication of the NAED. Reprinted with permission. A study recently published in the journal Lighting Research & Technology explored human preference related to light source color. The results challenge the ability of the color rendering index (CRI) metric to predict […]

Study: Architects Want More Digital Support, Good Advice, Transparency from Manufacturers

Architects are calling on manufacturers of building products and materials to advance their digital capabilities, as well as their ability to consult and advise customers in the many phases of construction projects, according to a study published by The American Institute of Architects (AIA). The Architect’s Journey to Specification assesses the cultural, technical, and informational […]

Plant Roots in the Dark See Light

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 […]

CLTC’s Advanced Daylighting Lab Gets a Facelift

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 […]

LRC: Tailored Lighting Improves Quality of Life for Persons with Alzheimer’s Disease

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 […]

DOE Publishes CALiPER Snapshot on TLEDs

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 […]

DOE Publishes New Forecast of Energy Savings from LED Lighting

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 […]
