Wetland and Amphibian Lighting: Managing Light Around Water and Breeding Areas

Amphibian lighting starts by avoiding unnecessary nighttime light near wetlands and breeding habitat. When lighting is necessary for a roadway, path, facility, or operations task, the practical approach is to contain it to that task, limit when it operates, evaluate spectrum as one part of the design, and verify the installed condition with site-specific ecological and regulatory input.

Seasonal Dimming Schedules for Wildlife-Sensitive Areas

A wildlife lighting schedule is a documented, site-specific seasonal dimming plan that changes roadway or public-area lighting timing and levels during recurring periods of wildlife sensitivity while retaining lighting needed for the location. It should be built from local habitat information, the purpose of the lighting, applicable requirements, field validation, and a review process, not from a universal preset.

Spectral Power Distribution vs. CCT for Ecological Outdoor-lighting Evaluation: Why SPD Matters More

For ecological outdoor-lighting evaluation, spectral power distribution (SPD) is more informative than correlated color temperature (CCT) because it shows how a source’s output is distributed across wavelengths. CCT describes apparent color, while ecological effects also depend on the amount, direction, timing, duration, setting, and organisms exposed to the light.

Eco-Friendly Streetlights: Paving the Path for Sustainable Urban Illumination

Streetlights have always been a key part of city life, showing us the way at night and making our streets safe. Over time, as technology got better, streetlights changed too. We moved from gas lamps to electric bulbs and, now, to LED lights. These changes have been good for people, but they’ve also brought problems for wildlife.
