my red light also on ive tried quite a few batteries.. what brand do you guys use? This comes with a rather unique set of challenges, because what is polluting for one person can be acceptable or even desirable lighting for another. There are uses of light that are necessary at night, especially in cities; no ‘dark sky advocate’ would deny that. And there are obvious instances of excessive brightness and poorly designed lighting, which most reasonable people would agree is unnecessary and wasteful. But, there will also be instances that fall somewhere in an intermediary, gray area. These could be instances where the lighting does not obviously fall into one of the sub-categories of light pollution, or does not relate directly to one of the identified effects of light pollution, or is contested as a good by some stakeholders and a nuisance or excess by others. Or, it could be a new technological innovation that reduces energy consumption but will potentially increase skyglow—an emerging issue connected to LEDs (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]). In these instances, we will see the weighing of benefits versus negative effects by regulatory decision-makers. It is unclear how the current conception of light pollution can be used to resolve such conflicts, without drawing upon a larger moral framework—for example, a formulation of the precautionary principle, a definition of sustainable development, or perhaps an explicit focus on minimizing energy usage—that helps to elucidate exactly what an acceptable level of pollution is. And, different approaches may rely on rights-based or consequentialist moral frameworks. These may, in turn, offer different boundary conditions for what qualifies as acceptable levels of light pollution. For example, in 2007, a group of astronomers published the Starlight Declaration, asserting that access to the night sky should be an ‘inalienable right of humankind’ (Starlight Initiative, 2007 Starlight Initiative. (2007). Declaration in defence of the night sky and the right to starlight. La Palma: La Palma Biosphere Reserve. Retrieved 14 January, 2015, from [Google Scholar], p. 3). Adopting such a rights-based approach would likely yield different conclusions than, say, a cost-benefit analysis. We would then need to ask if light pollution is, or should be, beholden to one broader moral framework, or how different manifestations can be reconciled. If we recall the discussion of defining problems within policy as a means to guide action (Stone, 2002 Stone, D. (2002). Policy paradox: The art of political decision making. New York, NY: W. W. Norton & Company Inc. [Google Scholar]), the concept of light pollution therefore requires further parameters beyond the causes and effects listed above. Use this form to report problems with street lights, traffic lights, zebra crossings, illuminated signs or bollards. Energy conservation advocates contend that light pollution must be addressed by changing the habits of society, so that lighting is used more efficiently, with less waste and less creation of unwanted or unneeded illumination.[citation needed] Several industry groups also recognize light pollution as an important issue. For example, the Institution of Lighting Engineers in the United Kingdom provides its members with information about light pollution, the problems it causes, and how to reduce its impact.[10] Although, recent research[11] point that the energy efficiency is not enough to reduce the light pollution because of the rebound effect. The IDA, founded 30 years ago, gathers and disseminates light-pollution information and solutions. It has played a pivotal role in turning the tide in the light-pollution war. The IDA is winning over key sectors of the nonastronomical public — including government groups, sections of the lighting industry and electric utilities — arguing that good lighting for astronomers equals energy savings and more attractive surroundings for everyone else. To report a street light outage, a light going on and off (cycling), a light on during the day, vandalism, or any other problem with a street light, call the Street Light Outage Hotline or use the online form. For a comprehensive understanding of light pollution, contemporary discourse must be coupled with an exploration of the origins and emergence of the concept, which in turn requires a broad understanding of the development of urban nighttime lighting. Detailed historical studies into the technological innovations and social implications of artificial nighttime lighting have been published in the past few decades (e.g. Bowers, 1998 Bowers, B. (1998). Lengthening the day: A history of lighting technology. Oxford: Oxford University Press. [Google Scholar]; Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar]; Isenstadt, Maile Petty, & Neumann, 2014 Isenstadt, S., Maile Petty, M., & Neumann, D. (Eds.). (2014). Cities of light: Two centuries of urban illumination. New York, NY: Taylor & Francis. [Google Scholar]; Nye, 1990 Nye, D. E. (1990). Electrifying America: Social meanings of a new technology, 1880–1940. Cambridge: MIT Press. [Google Scholar]; Schivelbusch, 1988 Schivelbusch, W. (1988). Disenchanted night: The industrialization of light in the nineteenth century. (A. Davis, Trans.) London: University of California Press. [Google Scholar]). And, important studies on the social, economic, and legal aspects of nighttime lighting have also been published recently (e.g. Meier, Hasenöhrl, Krause, & Pottharst, 2014 Meier, J., Hasenöhrl, U., Krause, K., & Pottharst, M. (Eds.). (2014). Urban lighting, light pollution and society. New York, NY: Taylor & Francis. [Google Scholar]). The brief discussion below cannot do full justice to the in-depth explorations of nighttime lighting that these scholars have explored, nor to the various cultural and geographical nuances of historical developments in lighting. Rather, I would like to highlight the conditions within which light pollution arose, which puts us in a better position to assess our contemporary definition and ask how the framing of light pollution responds to the core problem discussed above. In particular, Sections 3.1 and 3.2 will highlight the shift away from how to light cities and, somewhat paradoxically, toward a desire for dark or natural nights. Put otherwise, 6. These four categories of light pollution are used (although with slightly different terms) by the International Dark-Sky Association, and cited elsewhere as well (e.g. 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]). As such, I am accepting these as the standard causes of light pollution. The problem is this: even assuming the big bang timescale, there has not been enough time for light to travel between widely separated regions of space. So, how can the different regions of the current CMB have such precisely uniform temperatures if they have never communicated with each other?9 This is a light-travel–time problem.10 Hi can someone help me! My flashlight won’t work.. anybody who had the same problem? You can now report a street light problem with your smartphone, so it is easier to report it from the location. Visit on your smartphone and select “Report Street Light Problem.” To solve the starlight problem, some creationists have proposed a change in the speed of light; this proposition became known as c-decay. The idea was first systematically advanced by creationist Barry Setterfield in his 1981 book The Velocity of Light and the Age of the Universe. Setterfield claimed that, at the date of creation, light traveled millions of times faster than it does today and has been decaying precipitously ever since (until it stopped at its present value coincidentally with the ability to detect small changes). This idea is fundamentally absurd and since its inception has been universally derided by scientists. The idea was supported into the late eighties by creationists whose claims became more and more bizarre in attempts to prop up their failing model, until it finally collapsed under the weight of the evidence against it. In 1988, the idea was given up by the major creationist organization Institute for Creation Research, which, in an attempt to distance themselves from the scientific debacle that c-decay had become, became vocal critics of it.[5] Testo Ultra Celuraid Muscle VigRX Plus Masculin Active Tonus Fortis Eron Plus Atlant Gel power up premium eracto Atlant Gel
