Mark Lien, industry relations manager for the IES, recorded an audio version of his free-verse column written for the May 2021 issue of LD+A. Titled “Beyond Sunset,” the poem traces the trajectory of lighting history from the origins of electricity to modern day.

Progressions: Beyond Sunset: A history of lighting in free verse

We recorded a special Forces of Change video interview in March 2020 to provide a report on the impact of COVID-19 on lighting professionals from the vantage point of some prominent individuals representing various roles within our industry. Moderator Mark Lien talked with Diane Borys (Noctiluca Lighting Design and Consulting), Megan Carroll (New York Digital), Erik Ennen (MNCEE), Bob Preston (Capital Electric Supply), and Randy Reid (Edison Report). Now in November 2020, eight months after the initital discussion, we're revisiting the impact of COVID-19 on Lighting Professionals.

The purpose of this article is to evaluate from a biological standpoint the rationale for the establishment of a Circadian Lighting standard put forward by UL under the direction of Dr. Mark Rea of the Lighting Research Center at Rensselaer Polytechnic Institute. This critique is limited in scope but also applies to utilization of the Circadian Stimulus (CS) calculator also developed by the LRC.

FIRES | Circadian Lighting: a Neuroscientist’s Perspective

Whether you call it “circadian lighting,” “biologically effective lighting,” or some other name, the principle is the same: the color and intensity of light can be used to regulate the timing of our biological clocks, or “circadian rhythms.” For architects and lighting designers, this is an opportunity to provide healthy and comfortable environments for building occupants.

Mark Lien chats with IES Past President and editor of the Edison Report Randy Reid about the 20th Anniversary of the Edison Report, the importance of integrity in reporting, the invasion of the IT conglomerates into the lighting industry as well as some of the new lighting technologies that he finds fascinating.

As our population continues to grow, farm land disappearing and an increased awareness of what goes into our produce, the need to increase yield without chemicals is a critical topic. Host Mark Lien and Dr. Pocock discuss using LEDs (irradiance, spectral composition, timing, duration) to program photochemical, photosynthetic, development and biochemical processes in plants and the development of a physiological biofeedback system to maintain or change LED physiological programs. In layman’s term growing to produce better, stronger, faster. This fascinating, ground-breaking, and often warm interchange should not be missed.  Dr. Tessa Pocock is a Senior Research Scientist at the Center for Lighting Enabled Systems and Applications (LESA) at Rensselaer Polytechnic Institute. After obtaining a Ph.D. in plant physiology in Canada she moved her research to Sweden as a recipient of a prestigious Marie Curie Fellowship. She joined RPI in 2014 after a decade in the European horticultural lighting industry where she oversaw over 800 LED spectral high throughput experiments on greens, herbs, and medicinal plants. She is co-inventor on three technology patents, has authored or co-authored three book chapters and twenty-one peer-reviewed articles and has spoken at over 27 international conferences.  “We work at the leading edge of LED systems engineering, plant photobiology,  plant physiology, and greenhouse environmental controls. Our goal is to develop, transfer and implement energy-efficient CEA lighting systems to reduce your operational costs and lower your carbon footprint. This means increased profitability without compromise. Join Greenhouse Lighting and Systems Engineering (GLASE) and become part of the first horticultural lighting technology hub.”

As if our lighting community needs more disruption, we are poised for a radical change in how we make, distribute and sell our products. We have experienced two digital revolutions already in communication and computation. We can communicate instantly across the globe at no charge and computers are integrated into our lives. Digital fabrication is the third digital revolution. When we can make our own lighting sources, heat sinks, optics and luminaires in our garage or locally at a store with a larger 3D printer (3D Kinkos?) then business as usual is over. Container loads from Asia, our sales and distribution network and other peripheral support processes cease when costs equalize though local 3D printing. This will happen incrementally at first then accelerate to exponential growth as we experienced with communication and computation. The revolution has already begun with choices of 3D printers available on Amazon Prime for under $200. The Lighting Research Center has expanded their LED Lighting Institute to include content on 3D printing. Nadarajah Narendran, Ph.D. is the Director of Research at the LRC and is the Professor teaching a hands-on 3D lighting class. He has been leading a team that conducts research and educational programs to accelerate the development and market transformation of lighting technologies. The seminar culminates with participants designing, building and evaluating their own lighting fixtures including custom 3D printed components. Please enjoy this conversation between Narendran and host Mark Lien on this timely issue impacting in our lighting community. Dr. Narendran leads a team that conducts research and educational programs to accelerate the development and market transformation of solid-state lighting technology. He is the Professor, School of Architecture, as well as Director of Research at the Lighting Research Center, Rensselaer Polytechnic Institute. He is a Fellow of the Illuminating Engineering Society. Winner of Rensselaer’s William H. Wiley Distinguished Faculty Award, Taylor Technical Talent Award (Best Technical Paper), and PEW Teaching Leadership Award.
