Outdoor Areas Lighting with LEDs – the Competition Between Scotopic Efficacy and Light Pollution

In this paper the effect of typical outdoor LED lamps on star visibility index SVI was analyzed. For those lamps the spectral power distribution SPD, the nearest color temperature CCT [K] and efficacy n [lm/W] are provided. For given lamp, the SVI has been defined as ratio of its scotopic flux to scotopic flux created by full moon. The calculations shows that, the use of lamps with low CCT does not significantly affect the of the value SVI. Unfortunately from an economic point of view, those kind of lamps are less attractive in applications because of their low n. Full Text: PDF ReferencesC. Rich, T.

Chronic exposure to dim artificial light at night decreases fecundity and adult survival in Drosophila melanogaster

The presence of artificial light at night is expanding in geographical range and increasing in intensity to such an extent that species living in urban environments may never experience natural darkness. The negative ecological consequences of artificial night lighting have been identified in several key life history traits across multiple taxa (albeit with a strong vertebrate focus); comparable data for invertebrates is lacking. In this study, we explored the effect of chronic exposure to different night-time lighting intensities on growth, reproduction and survival in Drosophila melanogaster. We reared three generations of flies under identical daytime light conditions (2600lx) and one of four ecologically relevant ALAN treatments (0, 1, 10 or 100lx), then explored variation in oviposition, number of eggs produced, juvenile growth and survival and adult survival. We found that, in the presence of light at night (1, 10 and 100lx treatments), the probability of a female commencing oviposition and the number of eggs laid was significantly reduced. This did not translate into differences at the juvenile phase: juvenile development times and the probability of eclosing as an adult were comparable across all treatments. However, we demonstrate for the first time a direct link between chronic exposure to light at night (greater than 1lx) and adult survival. Our data highlight that ALAN has the capacity to cause dramatic shifts in multiple life history traits at both the individual and population level. Such shifts are likely to be species-specific, however a more in depth understanding of the broad-scale impact of ALAN and the relevant mechanisms driving biological change is urgently required as we move into an increasing brightly lit future.

Catherine Rich, Travis Longcore. Ecological Consequences of Artificial Night Lighting2006458$65(hardcover)$35(paperback)1559631287(hardcover)1559631295(paperback) The world at night is illuminated artificially mainly by urban lighting, but also fires, gas flares, and light-induced fisheries (www.ngdc.noaa.gov/dmsp/image/poster_world.jpg). This edited volume is the best source for the increasingly recognized environmental impact of artificial light on the living world. Artificial lighting disrupts animals by disorienting them at night, increasing their exposure to predation or conversely to abundant food sources, altering light-sensitive endocrine systems, and disrupting crepuscular and nocturnal mating, signaling, and dispersal. The best-known examples of these disruptions are confusion and mortality of migrating birds at lighted towers and buildings and the disorientation of sea turtle hatchlings returning to the sea. This is just a fraction of the ecological effects of night luminescence, of which only a small portion are documented. Fifteen chapters cover effects of artificial lighting on mammals, birds, reptiles, amphibians, fishes, invertebrates (mostly insects), and plants. The book was an outgrowth of the first and only conference on Ecological Consequences of Artificial Night Lighting, held in Los Angeles in 2002. The volume is organized in sections based on the taxonomy of animals, plus one chapter on plants, an introduction, and a synthesis section. Each of six larger sections is punctuated by a passage …

The Urban Wildlands Group, a Los Angeles–based conservation organization, convened a gathering of ecologists in 2002 to review the state of knowledge about the ecological consequences of artificial night lighting. This book provides edited proceedings from that conference. When New York City’s Pearl Street Station opened in 1882, the age of modern urban lighting was ushered in. Coincidentally, this was also a time when large optical refracting telescopes were built. By the 1950s, astronomers were complaining that “sky glow” from city lights were keeping them from doing their work. Sky glow happens when lights from urban areas reflect off clouds, causing light from even a small urban area to obliterate much of what there is to see in the night sky. The effect was most problematic in the western United States, location of several large telescope facilities and the traditional home of big, starry skies. By 2002, nine U.S. states and one entire country - the Czech Republic - had adopted so-called dark sky provisions, and 11 other states were considering similar laws. These legal efforts were based on aesthetic concerns. Some statistics frequently quoted came out of the First World Atlas of the Artificial Night-Sky Brightness (2001): half of the world’s population has never seen the Milky Way, 40 percent of Americans no longer have to adjust their eyes to night vision, two thirds of the world's population lives under light-polluted night skies. In March 2006, the National Park Service’s Night Sky Team released comprehensive data on the amount of light in the night sky in national parks, finding pollution in places that once seemed distant from urban centers. But to paraphrase one of this book’s editors, the idea that light pollution might pose a broad problem for whole ecosystems remained mostly in the gray literature. The topic is relatively new and unstudied and does not even have proper terminology yet. Lighting professionals and environmental regulators speak of “lux” to communicate a quantity of visible light. But for ecological purposes, “lux” fails to express the fact that different light sources

Ecological light pollution

Ecologists have long studied the critical role of natural light in regulating species interactions, but, with limited exceptions, have not investigated the consequences of artificial night lighting. In the past century, the extent and intensity of artificial night lighting has increased such that it has substantial effects on the biology and ecology of species in the wild. We distinguish “astronomical light pollution”, which obscures the view of the night sky, from “ecological light pollution”, which alters natural light regimes in terrestrial and aquatic ecosystems. Some of the catastrophic consequences of light for certain taxonomic groups are well known, such as the deaths of migratory birds around tall lighted structures, and those of hatchling sea turtles disoriented by lights on their natal beaches. The more subtle influences of artificial night lighting on the behavior and community ecology of species are less well recognized, and constitute a new focus for research in ecology and a pressing conservation challenge.
