New LRC Study Tests the Impact of Circadian Light on Alertness in Office Workers

In 2017 the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute published a groundbreaking study showing that office workers who receive a robust dose of circadian-effective light experience better sleep, and lower levels of depression and stress, than those who spend their days in dim or low light levels. The team of LRC researchers, led by Dr. Mariana Figueiro and sponsored by the U.S. General Services Administration, measured existing light levels for 109 participants at five federal office buildings designed to maximize daylight availability indoors. The research team found that even in open offices with many, large windows, office workers were not receiving enough light to stimulate their circadian system during the day, due to factors such as season, cloud cover, desk orientation, and window shade position.

Designing With Tunable White Light in Focus at the National Lighting Bureau’s Annual Lighting Forum

Relying on tunable white light “is the best, most-affordable way to ‘future-proof’ your work and designs and ensure very high performance.” So said Terry Clark, Founder and Chairman of the Board of Finelite, Inc., while participating in the National Lighting Bureau’s Annual Lighting Forum as one of three panelists focused on new and emerging developments in tunable white light; i.e., lighting whose color and other elements can be adjusted to meet a variety of needs and preferences. Other panelists included Brent Protzman, Ph.D., Director of Building Science and Standards Development, Lutron Electronics, Inc., and Sandra Stashik, P.E., F.IES, LEED AP, Director, Strategic Specification Development, Acuity Brands Lighting. EdisonReport Editor and Publisher Randy Reid moderated the discussion. Read more »

LRC Releases Free, Open Access Circadian Stimulus Calculator

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has recently released a free, open-access circadian stimulus (CS) calculator to help lighting professionals select light sources and light levels that will increase the potential for circadian-effective light exposure in architectural spaces, utilizing the CS metric. Developed by LRC researchers, the CS metric is a new way to quantify light’s impact on acute melatonin suppression, a marker of circadian system activation. Read more »

Warm Dimming and the Future of LED

As LED lighting grows in acceptance and popularity, so does the need for better and more ranging color quality. Traditionally, LED lighting gave off a stark white, cool glow that was harsh on the eyes and made it difficult to use as a primary lighting source. Warm-dim LED technology has toned down that cool coloring, dynamically shifting the current and future applications of LED lighting management systems. Dimmability with a warm glow effect creates more opportunities than ever for LED lighting management systems. Read more »

Joint Position Paper by LightingEurope and the IALD on Human Centric Lighting

Light has been known for a long time to enable sight, safety and orientation. However, light is not limited to facilitate vision, it has the potential to achieve far more than this. Science has shown that light facilitates powerful non-visual effects on humans. Light has the ability to improve cognitive performance, it can energize, increase alertness or ease relaxation. It can improve mood, as well as stabilize the sleep-wake cycle of people. Therefore, it can be understood that light impacts people’s wellbeing and performance. In fact, the true value of light lies in the combination of excellent visual, biological and emotional effects of light. LightingEurope uses the terminology “Human Centric Lighting” for lighting that brings such benefits to the users. A product or system can only be “Human Centric” within the context of people, time and space, thus within a specific application. Therefore, Human Centric Lighting requires the integration of these effects in the lighting design. Read more »
