An area of growing research and practice is using lighting to help control agricultural pests. This can include horticultural lighting in indoor growing facilities (aka controlled environment agriculture or CEA) or nighttime treatment with specific wavelengths on outdoor crops. Greenhouse growers have long known that introducing supplemental grow lights to greenhouses can dramatically change [...]

New research from the University of Zaragoza in Spain quantifies how the aging eye restricts the amount of circadian light reaching the retina based on photopic illuminance reaching the corneal plane and considering the optical density of an aging crystalline lens. As the researchers state: “As a result of the described behavior, retinal illuminance may [...]

A Belgian thermal management company named Diabatix nv is offering custom-designed heat sinks that use artificial intelligence/machine learning (AI/ML) generative design to create computer-generated shapes that can be optimized to achieve different engineering goals. Generative design is a process that uses algorithms and machine learning techniques to create and optimize designs based on specified design [...]

  In January, the Design Lights Consortium (DLC) published a new report about quantifying the non-energy benefits (NEB) of networked lighting controls (NLC). The most valued non-energy benefits varied by stakeholders, but included: extending the life of lighting equipment improved safety and security reduced maintenance improved light quality The top three takeaways of the report are: [...]

New York City, San Francisco, Washington D.C., Boston, and St. Louis are all preparing to fine building owners who fail to comply with new local regulations that in most cases, limit large buildings’ greenhouse gas emissions and/or curb energy usage. The earliest of the fines will go into effect this month in San Francisco. This [...]

Toshiba Corporation has unveiled a new photoluminescence technology, a novel phosphor that delivers excellent solubility in polymers or organic solvents, where it is transparent and colorless under visible light, and that emits persistent red-light emissions under UV light, with excellent color purity and six times the luminescence of current phosphors. These characteristics open up many [...]

A company named Photon Group created a mobile APP called, J’Ignite Ma Rue,” which enables citizens to control the streetlights in their neighborhood. Currently, eleven towns in France are allowing citizens to use the APP to control local streetlights. The primary benefits are saving energy by allowing citizens to turn down or off the lights [...]

A Dutch company, Sunne, designed the Sunne Lamp. Sunne is a self-powered solar light that captures, stores, and produces light indoors without the need for an external plug. By day, it harvests energy from sunlight while hanging in the window and stores it in its integrated battery. As evening falls, it starts to glow, powered [...]

I recently did a web search for GroAdvisors, one of the subsidiaries of Lighting Science Group Corporation (LSGC), and found their website was replaced with a 404 error message. I remember the big news in December 2021 when Healthe filed for bankruptcy, but those news stories never mentioned LSGC, nor any of its subsidiaries. I [...]
