Before buying an LED bulb you could check the specifications to see if it compatible with any type of dimmer switch. Most are not. Also since LED bulbs as so new (for residential lighting) there are not yet many standards followed for their operation. Some specialty LED bulbs are beginning to become available with dimming systems specially design for that type of bulb. In the night, the polarization of the moonlit sky is very strongly reduced in the presence of urban light pollution, because scattered urban light is not strongly polarized.[84] Polarized moonlight can’t be seen by humans, but is believed to be used by many animals for navigation. It is worthwhile to quickly note that, as with most transformational technologies, nighttime lighting has not always been met with open arms. Hasenöhrl (2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar], p. 105) notes that while the introduction of new lighting technologies was in general positively received, this did not imply universal endorsement or ‘a universal devaluation of the “dark night” as a whole’. The consequences of artificial nighttime lighting have been under debate since the nineteenth century, and some criticisms of artificial nighttime lighting can be found even earlier.55. Criticisms can be found as early as 1662, when a London pastor stated ‘We ought not to turn day into night, nor night into day … without some very special and urgent occasion’ (Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar], p. 74). This was due to the disruption of the perceived natural (Christian) order that such lighting may cause. However, most criticisms are found in the nineteenth century onward, and specifically around times of transition between technologies. Early objections were often esthetic, however moral objections can also be found (Hasenöhrl, 2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar]). There are documented criticisms of artificial nighttime lighting in astronomy-related literature as early as 1866 (Sperling, 1991 Sperling, N. (1991). The disappearance of darkness. In D. L. Crawford (Ed.), Light pollution, radio interference, and space debris (Vol. 17, pp. 101–108). San Francisco, CA: Astronomical Society of the Pacific Conference Series. [Google Scholar]). Already in the 1880s, Alexander Pelham Tottler—generally regarded as the originator of the scientific study of lighting—identified issues with street lighting that predict modern debates. For example, he argued that too much light is wasted, and that glare causes safety concerns (Bowers, 1998 Bowers, B. (1998). Lengthening the day: A history of lighting technology. Oxford: Oxford University Press. [Google Scholar]). Naturalists and artists expressed ambiguity (at best) towards artificial light as early as the 1920s (Nye, 1990 Nye, D. E. (1990). Electrifying America: Social meanings of a new technology, 1880–1940. Cambridge: MIT Press. [Google Scholar]), and by this time there were already some calls for lighting engineers to reduce urban brightness (Isenstadt, 2014 Isenstadt, S. (2014). Good night. Places Journal. Retrieved 22 October, 2014, from https://placesjournal.org/article/good-night/[Crossref] [Google Scholar]).View all notes The most outspoken critics have been astronomers, as reduced stellar visibility has been a long-noticed effect of urban lighting (Sperling, 1991 Sperling, N. (1991). The disappearance of darkness. In D. L. Crawford (Ed.), Light pollution, radio interference, and space debris (Vol. 17, pp. 101–108). San Francisco, CA: Astronomical Society of the Pacific Conference Series. [Google Scholar]). Still, in the larger narrative of lighting technologies these objections were the exception—nighttime lighting was mostly seen as necessary and desirable for modern urban life (Hasenöhrl, 2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar]). The two main reasons street lights stop working are: Hi! A few minutes ago, I had the same problem. I also dropped my camera and the red light won’t disappear. I’ve tried other batteries but it didn’t work. After 30 minutes of changing the batteries it worked again. I suggest you use AA LR6 batteries. They have to be from the SAME brand. Don’t use 2 different brand batteries. I hope it will work! (Also, please use NEW batteries. I changed my batteries with old ones and that’s probably why it didn’t work after 30 minutes) Download and complete the attachment to street light application form (PDF, 339.5 KB). Occasionally, the Check Engine light comes on when nothing is wrong with the car, Mazor says. It could be a temporary problem caused by a change in humidity or other factors. In such cases, the light should go off by itself after a short time. Please use this form to report a lighting issue. Some types of light sources are listed in order of energy efficiency in the table below (figures are approximate maintained values), and include relative visual skyglow impacts.[88][89] With over 54,000 lights, we depend on citizens to report problems. When reporting a problem, please provide as much information as you can about the location, especially pole numbers, adjacent addresses, and side of the street. If you phone in, you may get voice mail, so please leave a brief message with the previously mentioned information.  But not all colors of light have the same effect. Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night. And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown. 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 https://www.starlight2007.net/ [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.
