  Cornell University researchers have pioneered a groundbreaking method to watermark videos using light, addressing the urgent problem of video manipulation in an era dominated by generative artificial intelligence and rapidly spreading misinformation. Their innovation, named “Noise-Coded Illumination for Forensic and Photometric Video,” involves embedding a secret, unique code directly into the light emitted by [...]

  UC Davis researchers at The Color Lab have discovered that amber lighting has significant soothing effects on stress and anxiety, and they are now working on implementing human-centric lighting designs aimed at optimizing well-being in real-world settings. This innovative research is the product of an interdisciplinary collaboration between the California Lighting Technology Center (CLTC) [...]

The accelerating demand for electricity is reshaping the energy landscape, presenting both challenges and unprecedented opportunities for the electrical distribution industry. As one of the pivotal sectors positioned to drive this transformation, electrical distributors are tasked with supplying the critical services, products, and innovative solutions that will power the future. To guide its members through [...]

  Researchers from the University of St Andrews and the University of Cambridge have achieved a breakthrough in wireless optical communications by using OLEDs (organic light-emitting diodes)—commonly found in smartphone screens and televisions—as fast, long-distance transmitters for visible light communication (VLC), also known as Li-Fi. VLC uses light waves rather than radio frequencies to send [...]

  Defense Advanced Research Projects Agency (DARPA) Persistent Optical Wireless Energy Relay (POWER) program is bringing futuristic visions closer to reality by achieving record-setting results in long-distance, wirelessly beamed power. This initiative aims to revolutionize the delivery of electricity, particularly for military and humanitarian operations where the logistics of providing energy across challenging terrain are [...]

  In a recent research paper titled “A New Way to Understand the Color Rendition Performance of Multi-Primary Light Sources” published in Leukos, the researchers introduce a novel approach to evaluating and characterizing the color rendition performance of tunable, multi-primary light sources—a class of modern illumination technologies with significant applications in architecture, entertainment, and display [...]

By Bill Chan, President, LiteController Inc. Melanopic Equivalent Daylight Illuminance (M-EDI) is widely used to assess circadian-effective lighting, but is it truly optimized for human biological responses? What is M-EDI? Melanopic Equivalent Daylight Illuminance (M-EDI) is a metric used to evaluate how light impacts our circadian rhythms, based on the sensitivity of Melanopsin, a photopigment [...]

A new study was published last month, Non-Image-Forming Effects of Daytime Electric Light Exposure in Humans: A Systematic Review and Meta-Analyses of Physiological, Cognitive, and Subjective Outcomes, in the IES journal Leukos. Light exerts numerous nonvisual or non-image-forming, effects – such as its impact on melatonin suppression, circadian phase-shifts, sleep quality, and alertness. While research [...]

A recent study conducted by researchers at Shanghai Jiao Tong University School of Medicine has uncovered a potential link between blue light exposure and an increased risk of kidney stone formation, raising important questions about the health impacts of modern lighting and screen use. Kidney stones are a growing global health concern, traditionally associated with [...]
