The use of full cutoff fixtures can allow for lower wattage lamps to be used in the fixtures, producing the same or sometimes a better effect, due to being more carefully controlled. In every lighting system, some sky glow also results from light reflected from the ground. This reflection can be reduced, however, by being careful to use only the lowest wattage necessary for the lamp, and setting spacing between lights appropriately.[86] Assuring luminaire setback is greater than 90° from highly reflective surfaces also diminishes reflectance. I have outwalked the furthest city light, ends the first stanza of Robert Frost’s poem ‘Acquainted with the Night’. For many contemporary urban dwellers, such a feat is becoming exceedingly difficult in our electrified, 24 h societies. While artificial nighttime illumination has brought with it many advances and possibilities, the negative consequences of its ubiquity and proliferation have only recently emerged as a topic of inquiry. Discourse is increasingly framing concerns about nighttime lighting via the concept of light pollution, particularly with respect to environmental effects. However, light pollution has received relatively little attention compared to other environmental problems, remaining scientifically and culturally ‘in the dark’ (Hölker et al., 2010 Hölker, F., Moss, T., Griefahn, B., Kloas, W., Voigt, C., Henckel, D., … Tockner, K. (2010). The dark side of light: A transdisciplinary research agenda for light pollution policy. Ecology and Society, 15(4), 13.10.5751/ES-03685-150413[Crossref], [Web of Science ®] [Google Scholar]). Equally important, the framing of environmental problems caused by artificial nighttime lighting via the concept of light pollution has received little critical attention. Understandings of light pollution are reliant on seemingly technical descriptions—light pollution is used to categorize and quantify the adverse effects of artificial nighttime illumination. But such a categorization carries an implicit normative judgment, and should not be accepted without critical reflection. The International Commission on Illumination, also known as the CIE from its French title, la Commission Internationale de l’Eclairage, will soon be releasing its own form of unified photometry for outdoor lighting. Wildlife:John Metcalfe at Citylab.com reported last year that lights are disorienting birds, with deadly results. “Many species migrate by night and are perilously dazzled by artificial illumination, for reasons we don’t yet completely understand,” Metcalfe wrote. “Lights on skyscrapers, airports, and stadiums draw birds into urban areas, where they smack into walls and windows or each other, or flap around and eventually perish from exhaustion-related complications.” Current public lighting in Australia, particularly for minor roads and streets, uses large amounts of energy and financial resources, while often failing to provide high quality lighting. There are many ways to improve lighting quality while reducing energy use and greenhouse gas emissions as well as lowering costs.[33] But what of the details of the transition between the miraculous transmission of light over great distances to the relatively slow pace today, all accomplished on Day Four? Would this imply a transition region that still might be reaching the earth today? Might there be some implication for the Hubble relation, the general trend of increasing redshift with increasing distance? Alas, I do not know. These and many other questions must be addressed for my proposal to be taken seriously by fellow creation scientists. I hope that with time to reflect, discussion with others, and perhaps the work of others on my proposals may yield some insight into these and many more questions. I place this proposal before others to stimulate discussion. I identify a little-noticed issue in the normal formulation of the light travel time problem. In addition, I lay groundwork for the beginning of a new solution to the problem. This solution invokes similarity between creative acts of Day Four and other days of the Creation Week, but especially Day Three. The Day Three account suggests unusually fast growth for plants. In similar fashion, this possible new solution suggests unusually fast propagation of light on Day Four, probably by rapid expansion of space. This is an appeal to a miraculous event rather than a physical process to get distant starlight to the earth. It is not yet clear whether this suggestion could have testable predictions. If this is the correct way to look at the problem, it may be that we are seeing much of the universe in something close to real time. I briefly compare this possible solution to the light travel time to other previously published proposals. 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. Everyone has slightly different circadian rhythms, but the average length is 24 and one-quarter hours. The circadian rhythm of people who stay up late is slightly longer, while the rhythms of earlier birds fall short of 24 hours. Dr. Charles Czeisler of Harvard Medical School showed, in 1981, that daylight keeps a person’s internal clock aligned with the environment. The use of full cutoff lighting fixtures, as much as possible, is advocated by most campaigners for the reduction of light pollution. It is also commonly recommended that lights be spaced appropriately for maximum efficiency, and that number of luminaires being used as well as the wattage of each luminaire match the needs of the particular application (based on local lighting design standards). 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 https://darksky.org/ [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. Put exterior lights on motion detectors to reduce the unnecessary use of outdoor lighting, and direct illumination of lights towards the ground, not upwards (which is not efficient, and contributes to sky glow). If there is a problem with the electricity supply, we will need to inform the electricity supplier and could take more time to fix the light. Since its introduction by astronomers the concept of light pollution has been gaining momentum and widespread acceptance. Contemporary understandings of light pollution focus on categorizing the negative consequences of artificial lighting across a range of disciplines. Thus, it can be defined in many different ways, creating some issues with ambiguity (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]). However, efforts have been made to provide a universal definition and to codify negative effects, which go well beyond a sort of Luddism or a nostalgic pining for more darkness. The International Dark-Sky Association, arguably the leading authority on light pollution, defines light pollution simply as ‘any adverse effect of artificial light’ (IDA, 2014 IDA. (2014). International Dark-Sky Association. International Dark-Sky Association. Retrieved 15 January, 2015, from https://darksky.org/ [Google Scholar]). A more nuanced articulation of the concept states, ‘the unintended consequences of poorly designed and injudiciously used artificial lighting are known as light pollution’ (Gallaway, 2010 Gallaway, T. (2010). On light pollution, passive pleasures, and the instrumental value of beauty.
