What all definitions have in common—either explicitly or implicitly—is the goal of establishing a base upon which the negative effects of artificial nighttime illumination can be categorized. Toward this end, Gallaway’s definition opens us to the broader range of concerns embodied by the contemporary usage of the term—light pollution is not meant to condemn nighttime lighting as a whole, but rather specific uses and outputs of artificial lighting. These negative or undesired aspects of nighttime lighting can be subdivided into four categories: skyglow, glare, light trespass, and clutter.66. 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.View all notes Skyglow is light sent upward (directly or reflected) and scattered in the atmosphere, causing artificial ambient brightness and decreasing stellar visibility (Mizon, 2012 Mizon, B. (2012). Light pollution: Responses and remedies (2nd ed.). New York, NY: Springer.10.1007/978-1-4614-3822-9[Crossref] [Google Scholar]). This is the orange haze often seen above cities, and the largest burden for astronomy. It has also arguably been the dominant focus of efforts to quantify light pollution, as some landmark studies rely on satellite imagery (e.g. Cinzano, Falchi, & Elvidge, 2001 Cinzano, P., Falchi, F., & Elvidge, C. D. (2001). The first world Atlas of the artificial night sky brightness. Monthly Notices of the Royal Astronomical Society, 328, 689–707.10.1046/j.1365-8711.2001.04882.x[Crossref], [Web of Science ®] [Google Scholar]). The other three forms of light pollution are more commonly experienced hinderences in daily life: glare occurs when excessive brightness reduces visibility (e.g. a floodlight at eye level), light trespass is unwanted or unintended light (e.g. light shining into your bedroom window at night), and clutter is caused by over-illuminated clusters of light sources (e.g. signage and advertising) (IDA, 2014 IDA. (2014). International Dark-Sky Association. International Dark-Sky Association. Retrieved 15 January, 2015, from https://darksky.org/ [Google Scholar]; 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]). Research is also examining the effects on flora and fauna, especially birds, bats, turtles, and insects. While a few species benefit from increased brightness at night, many are negatively affected. Perhaps most notable are the effects of artificial light on migrating birds and newly hatched turtles attempting to reach the ocean (Gallaway, 2010 Gallaway, T. (2010). On light pollution, passive pleasures, and the instrumental value of beauty.

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]). The effects of artificial lighting on human health first emerged in the late 1960s, but have gained more attention by medical researchers in the last few decades. Pottharst and 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]) summarize ongoing research correlating nighttime lighting—and more specifically disruptions to our circadian rhythm—to insomnia, depression, obesity, loss of night-vision, and the suppression of melatonin (which is potentially linked to an increased risk of breast cancer). While the precise connection between human well-being and exposure to artificial nighttime lighting requires further research, the World Health Organization has nevertheless stated that exposure to certain lights at night is likely a carcinogen (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]).

The method for best reducing light pollution, therefore, depends on exactly what the problem is in any given instance. Possible solutions include: If you notice a streetlight or outdoor area light is out, please use this form to let us know about the problem. Thank you for helping to keep our community safe. The third solution is not much discussed anymore. It relied upon some speculative hypothesis about the nature of light that has never been demonstrated. Very few creationists embraced this solution anyway, and those who once did mention this solution normally offered it as a hypothetical possibility not necessarily with endorsement. For a critical discussion of this theory, please see Akridge (1984). Monochromatic yellow light (λ = 594 nm) passes throught two slits with a slit spacing of 0.125 mm and forms an interference pattern on a screen that is positioned 14.5 m away. Determine the distance between the fifth bright spots on opposite sides of the central bright spot. This did not fix the problem. The two bulbs were still coming on dimly at the same time when pressing the brake pedal.  Now I should turn this into a contest. You electrical wizards out there may already have a good guess.  In all my years of working on all types of cars – almost every time I have run across a problem with front and rear lights doing weird things – and by that I mean not glowing brightly, cross feeding, coming on at the wrong time, intermittent operations, etc, etc, it has almost always turned out to be an electrical grounding problem.  And it was no different here.  I took a close look at the grounding strap connecting points and I could see corrosion.  I applied some dielectric grease and squeezed the contact points together with some needle nose pliers and Wallaah – the running bulb went off and the brake light bulb came on super bright.  A good day and another one fixed.

Determine the distance between the fifth bright spots on opposite sides of the central bright spot. A Harvard study shed a little bit of light on the possible connection to diabetes and possibly obesity. The researchers put 10 people on a schedule that gradually shifted the timing of their circadian rhythms. Their blood sugar levels increased, throwing them into a prediabetic state, and levels of leptin, a hormone that leaves people feeling full after a meal, went down. Keep unnecessary lights off when going camping and staying in cottages because they can interfere with the health and the natural behavior of nocturnal animals like salamanders. Report a street light problem Reducing light pollution implies many things, such as reducing sky glow, reducing glare, reducing light trespass, and reducing clutter. The method for best reducing light pollution, therefore, depends on exactly what the problem is in any given instance. Possible solutions include: 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. Turn off unnecessary lights outdoors and replace outdoor lights with low-glare versions. The International Dark-Sky Association certifies lights for low-glare and efficiency, and the company Starry Night Lights produces low light pollution lighting that is more environmentally-friendly. Some lights get extra bright while others run dim. Bulbs may even be popping, and an electronic appliance or two may have died recently. This is a condition that will continue to be destructive to equipment in you home.
