The Dark Side of Bright Nights: Rethinking Holiday Illumination
As the holiday season begins, cities and neighborhoods around the world participate in a collective ritual of illumination. While these displays spark joy, they also create a measurable global phenomenon. NASA satellite data reveals that during the holidays, nighttime lights in major metropolitan areas shine 20 to 50 percent brighter than the rest of the […]
Everyone can participate in measuring light pollution!
Measuring light pollution relies on a combination of physical instruments, digital tools, and mapping methods that help quantify how artificial light alters nighttime brightness. One of the main tools that are used in monitoring is the Sky Quality Meter (SQM), which provides numerical readings of sky luminance. SQMs allow users to record sky brightness in different […]
Project presented at Regional Erasmus+ Cluster Meeting and Contact-Making Seminar in Colombia
The city of Bogota, Colombia, hosted the Regional Erasmus+ Cluster Meeting and Contact-Making Seminar for Latin America and the Caribbean. On October 7–8, 2025, our partner organization from Germany, represented by Daniel Almedia, showcased our joint project, VET EcoLume, specifically the component “Education institutions as beacons of green behaviour.” The event was organized by the […]
Illuminating a Sustainable Future: Five Pillars for Tackling Light Pollution
The perpetual glow of modern civilization has created an invisible, yet profoundly harmful, environmental challenge: light pollution. It’s not simply a matter of wasted energy or blocked stargazing; it’s a form of environmental contamination that disrupts sleep, interferes with nocturnal wildlife behavior, and obscures one of humanity’s oldest natural resources, the night sky. To reverse this […]
Does darkness matter more than we think?
In one of our previous articles „From Darkness to Light: Sustainable Solutions for Light Pollution Mitigation“ we have discussed basics of light pollution and it`s effects on human health, environmental and economical impact. Why Darkness Matters Darkness is more than just the absence of light but it is a natural condition that has shaped life […]

Collaborative Session: Shaping the Future of Light Pollution Mitigation Education
In February 2025, as part of the VET-EcoLume project, we hosted a Collaborative Session—an online conference that brought together more than 35 stakeholders from Croatia, Colombia, Chile, Germany, and Estonia. This session served as a crucial platform for engaging with experts, educators, and practitioners dedicated to combating light pollution and promoting sustainable urban lighting solutions. […]
From Darkness to Light: Sustainable Solutions for Light Pollution Mitigation
Light pollution is one of the most pervasive yet underappreciated environmental issues of our time. The excessive or misdirected artificial light that floods urban areas and spills over into natural spaces has significant consequences for both human health and the environment. While it’s easy to overlook the effects of too much light in our cities, […]
