There have been major qualitative and quantitative changes in outdoor lighting technology in the last decade. The level of skylight caused by outdoor lighting systems is growing at a very high rate, about 20 percent per year nationwide. In addition, the spectral distribution of man-made light pollution may change in the next decade from one containing a few mercury lines to one containing dozens of lines and a significantly increased continuum level. Light pollution is presently damaging to… 

Optimizing Lighting of Rural Roads and Protected Areas with White Light: A Compromise among Light Pollution, Energy Savings, and Visibility

ABSTRACT The broad implementation of light emitting diode (LED) light sources in public lighting has become a revolution in recent years. Their low power consumption and good performance (extremely

Red is the new black: how the colour of urban skyglow varies with cloud cover

The development of street lamps based on solid-state lighting technology is likely to introduce a major change in the colour of urban skyglow (one form of light pollution). We demonstrate the need

National Scale Spatial Variation in Artificial Light at Night

It is demonstrated that, although artificial light at night increases with human density, the amount of light per person decreases with increasing urbanization.

Artificially lit surface of Earth at night increasing in radiance and extent

The first-ever calibrated satellite radiometer designed for night lights is used to show that from 2012 to 2016, Earth’s artificially lit outdoor area grew by 2.2% per year, with a total radiance growth of 1.8% peryear.

Design and implementation of an illumination system to mimic skyglow at ecosystem level in a large-scale lake enclosure facility

This work presents the first experimental setup to mimic skyglow at ecosystem level outdoors in an aquatic environment with white light-emitting diodes at a large-scale lake enclosure facility and can be adapted to other outdoor and indoor skyglowing experiments.

Measurement and distribution of urban light pollution as day changes to night

Light pollution has a serious impact on astronomical observations and ecological balance. So far, most scholars have carried out field measurements of urban sky glow luminance using satellite data.

An analysis of light pollution at the Thirty Meter Telescope candidate sites

Light pollution can create difficulties for astronomers attempting to observe faint objects in the night sky. Light from a local small town can be just as intrusive as light from a large city in the

Chapter 15. Light pollution and the impact of artificial night lighting on insects

The creation of urban environments has significant impacts on animals and insects throughout the world (Niemelä et al. Chapter 2; Caterall, Chapter 8; Nilon, Chapter 10; van der Ree, Chapter 11;
