The effectiveness of using full cutoff roadway lights to combat light pollution has also been called into question. According to design investigations, luminaires with full cutoff distributions (as opposed to cutoff or semi cutoff, compared here[87]) have to be closer together to meet the same light level, uniformity and glare requirements specified by the IESNA. These simulations optimized the height and spacing of the lights while constraining the overall design to meet the IESNA requirements, and then compared total uplight and energy consumption of different luminaire designs and powers. Cutoff designs performed better than full cutoff designs, and semi-cutoff performed better than either cutoff or full cutoff. This indicates that, in roadway installations, over-illumination or poor uniformity produced by full cutoff fixtures may be more detrimental than direct uplight created by fewer cutoff or semi-cutoff fixtures. Therefore, the overall performance of existing systems could be improved more by reducing the number of luminaires than by switching to full cutoff designs. Section 2 discusses the moral and political significance of framing problems, in relation to the novel environmental problem of excess artificial nighttime lighting in cities. Section 3 then analyzes the concept of light pollution in detail. Here, both the origins of the concept and its current manifestations are presented, in order to provide a more comprehensive understanding of light pollution. Section 4 returns to the question of how light pollution frames concerns and possible responses, and discusses two interrelated questions: the potential limitations of the concept as a normative or prescriptive tool, and the ambiguities and inconsistencies in its practical application that require clarification. Thus, first steps are taken in dissecting the ethical significance of the concept of light pollution and the role it can play in addressing the adverse effects of artificial nighttime lighting. I have a problem with the red light, I haven’t used the camera for 6 months or more and today when I was going to take the picture, the first film came out white but the second picture I took came out normal. I took the film out because it also marked that it has 10 films but it has like 4. The red light its still going on and I don’t know whats going on. Can someone help me? Also, I haven’t drop the camera, its been sitting on my shelf for a while. Today I ended up checking everyones tail lights out in the parking lot. It all started when Kristin ask for help in repairing her inoperative brake likes. After fixing those we checked out all the lights on Kaias wagon and then my wife, Linda, drove in in her 1993 300D, so I decided to check those as well. Senator Bernie Sanders took the spotlight Monday in a live-streamed town hall focused on inequality. The event came a couple of days after an op-ed in The Guardian in which he criticized “corporate media” for ignoring the rise of oligarchy in the US. The relationship between safety and lighting at night is complex at best, and often controversial. Historical surveys into the origins of public nighttime lighting (e.g. Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar]) describe the storied relationship between the value of safety and lighting efforts. Lighting served the practical function of making nighttime travel safer, but also the symbolic function of protection from the evils of the night (spirits, demons, etc.). In contemporary discourse, the exact relationship between safety and security and nighttime lighting remains contentious, with various studies proving or disproving a correlation (Pottharst & Könecke, 2013 Pottharst, M., & Könecke, B. (2013). The night and its Loss. In Space-time design of the public city, urban and landscape perspectives (Vol. 15, pp. 37–48). Dordrecht: Springer.10.1007/978-94-007-6425-5[Crossref] [Google Scholar]). It is outside the scope of this paper to comment on these studies in detail, but it is important to note that advocates for mitigating light pollution often cite the possibility that less (or more wisely designed) lighting may improve safety and reduce crime (e.g. Bogard, 2013 Bogard, P. (2013). The end of night: Searching for natural darkness in an age of artificial light. New York, NY: Back Bay Books. [Google Scholar]; Henderson, 2010 Henderson, D. (2010). Valuing the stars: On the economics of light pollution. Environmental Philosophy, 7, 17–26.10.5840/envirophil2010712[Crossref] [Google Scholar]). If the lightbulb flickers, follow this troubleshooting procedure: Such a question may not strike you as entirely novel or revolutionary, as surely such questions are as old as attempts to illuminate our nights. But, the context in which this question is posed—the growing recognition of environmental and health-related problems caused or amplified by nighttime lighting—gives it new meaning. We are now seeking a transition in nighttime lighting strategies toward reducing the amount of illumination. And, it has been acknowledged that traditional approaches have been ineffective to date. Kyba, Hänel, and Hölker (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]) note that despite improvements to efficiency in lighting technologies, energy usage for outdoor lighting and artificial nighttime brightness continues to increase annually. Thus, a complete conversion to efficient lighting technologies alone (i.e. LEDs) is unlikely to reduce energy consumption or other unwanted consequences; new approaches to nighttime lighting must look beyond the narrow focus of improving efficiency. They summarize this necessary change in perspective by stating that, Please note that street lights are fixed as soon as possible, depending upon when crews are in the area and workload. 1. FPL does not own or maintain streetlights on aluminum poles located on major highways, like I-95 or the Florida Turnpike. If the check engine light comes on, here are some tips on what you should do: We own and look after most of the street lights in Kent. Parish and district councils own and look after some and some are privately owned. That light can cause pollution is a new idea for most people, and many may think it is not really very important except to astronomers. But light pollution interferes with living systems in many ways, causing, for example, sea turtles to lose their way to the sea, migrating birds to become confused and strike buildings, and plant seasonal cycles to be disturbed. It also affects human hormone cycles and our day-and-night cycles of sleep and wakefulness. Using light carelessly wastes energy, resources used to make the energy, and interferes with everyone’s visibility not only of stars but also of things on the ground that we need to see. 4. 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. Current calls for mitigation are often rested on an appeal to needs. For example, the International Dark-Sky Association cites needs-based principles of lighting as a way to minimize the negative effects of light pollution (IDA, 2014 IDA. (2014). International Dark-Sky Association. International Dark-Sky Association. Retrieved 15 January, 2015, from [Google Scholar]). It seems to follow that ‘unneeded’ nighttime illumination equates to light pollution, and therefore, contributes to the pre-defined negative effects. For, at the least, lighting deemed unnecessary wastes energy. This requires a clear justification for what is ‘needed’ nighttime illumination, which is both a quantitative and qualitative question. However, the moral terrain of such claims has been left largely unexplored. A needs-based approach requires that we can confidently point to criteria for needed lighting. Yet, as historic surveys on nighttime lighting makes clear, the blurring of symbolic and actual needs of nighttime lighting are complex at best, and needs are co-constituted by societal perceptions and values (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]). If policies aimed at light pollution mitigation adopt a needs-based approach, adequate reasoning should be given for why a different approach—say one geared toward preferences and desires—is insufficient.
