If you notice a street light that is not operating properly, and it is not due to an emergency circumstance (i.e. flooding, downed power line, earthquake, etc.), please use the form below to report the problem. Our team of Customer Care Agents will respond to your email in the order received, Monday through Friday. Unexpected high volumes may result in a delayed response. Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories,[5] and, like any other form of pollution, disrupts ecosystems and has adverse health effects[6][7] The temperature of the CMB is essentially the same everywhere5—in all directions (to a precision of 1 part in 100,000).6 However (according to big bang theorists), in the early universe, the temperature of the CMB7 would have been very different at different places in space due to the random nature of the initial conditions. These different regions could come to the same temperature if they were in close contact. More distant regions would come to equilibrium by exchanging radiation (i.e. light8). The radiation would carry energy from warmer regions to cooler ones until they had the same temperature. The 350 year project of illuminating our nights has produced a challenging situation. The desire for more and better lighting at night has left us with an overabundance of artificial illumination, and has produced a novel problem. The realization of lengthening the day is increasingly perceived as a loss of the night, and a new frame has emerged to give shape to these concerns. The story of light pollution goes back much further than the 1970s, in juxtaposition but nevertheless linked to the technical and social history of modern nighttime illumination. Importantly, the concept of light pollution re-frames certain aspects and uses of nighttime lighting technologies. If we return once more to the driving question (how much artificial light at night is appropriate?), we can appreciate that the concept of light pollution provides a new starting point, and not an end point, for discussions about the future of nighttime lighting.1010. I would like to thank the anonymous reviewer for this insight.View all notes Gaslight was followed by the invention of electric lighting in the latter half of the nineteenth century—the most profound technological development in lighting, and arguably one of the most important developments of modern infrastructure. Figuratively, electric lighting became synonymous with—and symbolic of—modern progress. For a Russian poet visiting New York City in the 1920s, the bright electric lights were perceived as modernity’s very medium (Isenstadt, 2014 Isenstadt, S. (2014). Good night. Places Journal. Retrieved 22 October, 2014, from https://placesjournal.org/article/good-night/[Crossref] [Google Scholar]). Aided by various technical advances, for example, floodlights, electric lighting quickly became a ‘sophisticated cultural apparatus’ that could be used for advertising, commemorating history, expressing civic pride, highlighting monuments, etc. (Nye, 1990 Nye, D. E. (1990). Electrifying America: Social meanings of a new technology, 1880–1940. Cambridge: MIT Press. [Google Scholar], p. 73). Via electrification, artificial nighttime lighting became, and remains, a prolific technological artifact capable of esthetic and ideological expression well beyond functional requirements.44. Neumann’s’ Architecture of the Night (2002a Neumann, D. (Ed.). (2002a). Architecture of the night: The illuminated building. New York, NY: Prestel. [Google Scholar]) is arguably the most important recent study of nighttime illumination in architectural history and theory, linking the history of nighttime lighting with the history of modern architecture. Neumann mainly focuses on the esthetic and expressive qualities of ‘illuminated buildings’ throughout the nineteenth and twentieth centuries, providing the first comprehensive catalogue of relevant architectural projects.View all notes We use more than 8,300 street lights of various types and wattages. What they have in common is that nearly every one has a photo control switch. This tells it to turn on at night and go off during the day. Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories,[5] and, like any other form of pollution, disrupts ecosystems and has adverse health effects[6][7] Dear sir, Good evening i want to know where the backlight settings that will make the key pad light to show on my Techno phone?. The tendency is for people to say that they feel safer in brightly lit areas, but statistics do not indicate that most crime-plagued areas are made safer by increased lighting. Studies are mixed but there are results indicating increased crime with increased lighting. This may be the result of people feeling safer when they actually aren’t, thus being lulled into taking fewer anti-crime precautions. 9. Morgan-Taylor (2014 Morgan-Taylor, M. (2014). Regulating light pollution in Europe: Legal challenges and ways forward. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution and society (pp. 159–176). New York, NY: Taylor & Francis. [Google Scholar]) provides a brief analysis of current regulatory efforts in Europe. France is cited as having perhaps the strongest law to date, which requires non-residential buildings to switch off exterior lights and window displays between 1am and 7am. Other examples cited include regions of Italy that have taken a technical approach, prohibited lights above a specific brightness to project above the horizontal. Additionally, an online appendix to the article by Kyba et al. (2014 Kyba, C., Hänel, A., & Hölker, F. (2014). Redefining efficiency for outdoor lighting. Energy & Environmental Science, 7, 1806–1809.10.1039/C4EE00566J[Crossref], [Web of Science ®] [Google Scholar]) lists all known regulations and ordinances that are currently in place, as well as their motivations and targets.

Additional images from Suomi NPP taken between 2010 and 2016 clearly show how light pollution is on the rise around the globe. 2) When changing all light bulbs into LEDs, all LEDs start to flicker. Nevertheless they work fine when changing only 15 or less bulbs. We are faced with a new problem: simply put, we have too much light at night. For centuries, more and better urban nighttime lighting was largely seen as desirable and necessary. However, following the rapid proliferation of electric lighting throughout the twentieth century, the impacts of artificial nighttime illumination have become a research interest—or rather concern—in a variety of disciplines. Nighttime lighting uses enormous amounts of energy, in addition to costing billions of dollars, damaging ecosystems, and negatively affecting human health.11. These effects are described in more detail in Section 3.3.View all notes With this emerging knowledge, continuing with the same use patterns and regulatory strategies can no longer be justified. We must rethink our urban nights. But, some amount of artificial light is, of course, still desirable and necessary at night. Therefore, our new problem comes with a novel question: how much artificial light at night is appropriate? The light travel time problem is one of the greatest challenges that recent creationists face today. Simply defined, if the universe is only thousands of years old as the Bible strongly suggests, then how can we see objects that are at light travel time distances far greater than a few thousand years? A popular unit of distance used in astronomy is the light year, the distance that light travels in a year. Multiplying the speed of light by the number of seconds in a year, we find that the light year is a little more than 9 × 1012 km. Obviously, using “normal” units of distance measurements such as meters or kilometers is woefully inadequate in astronomy, hence the definition of this new unit of distance. With the most straightforward approach to the biblical record and the vast distances in astronomy, we ought not to see any objects more than a few thousand light years away. Most of the objects visible to the naked eye are not this far away, so, as the light travel time problem normally is defined, most objects visible to the naked eye do not present a problem to the recent creation model.
