This is America’s elected leader — and he essentially, based on his first public response, ignored what the real problem is. And although the White House has come around to bipartisan proposals to very slightly improve background checks and ban bump stocks, the compromises amount to fairly small changes to America’s weak gun laws. In addition to skyglow, light trespass can impact observations when artificial light directly enters the tube of the telescope and is reflected from non-optical surfaces until it eventually reaches the eyepiece. This direct form of light pollution causes a glow across the field of view which reduces contrast. Light trespass also makes it hard for a visual observer to become sufficiently dark adapted. The usual measures to reduce this glare, if reducing the light directly is not an option, include flocking the telescope tube and accessories to reduce reflection, and putting a light shield (also usable as a dew shield) on the telescope to reduce light entering from angles other than those near the target. Under these conditions, some astronomers prefer to observe under a black cloth to ensure maximum dark adaptation. In one Italian regional lighting code this effect of stray light is defined as “optical pollution”[citation needed], due to the fact that there is a direct path from the light source to the “optic” – the observer’s eye or telescope. U.S. federal agencies may also enforce standards and process complaints within their areas of jurisdiction. For instance, in the case of light trespass by white strobe lighting from communication towers in excess of FAA minimum lighting requirements[13] the Federal Communications Commission maintains an Antenna Structure Registration database[14] information which citizens may use to identify offending structures and provides a mechanism for processing citizen inquiries and complaints.[15] The U.S. Green Building Council (USGBC) has also incorporated a credit for reducing the amount of light trespass and sky glow into their environmentally friendly building standard known as LEED. Determine the frequency of … (GIVEN: 1 m = 109 nm) a. … red visible light (λ = 650 nm) b. … violet visible light (λ = 420 nm) In establishing an acceptable level of polluting, some clarification of qualitative values will strengthen future decisions. Consider the research by Gallaway (2014 Gallaway, T. (2014). The value of the night sky. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution and society (pp. 267–283). New York, NY: Taylor & Francis. [Google Scholar]), who explores the instrumental value of the night sky for promoting the broadly held values of happiness and sustainability. He concludes by stating, ‘We suggest that estimating the night’s value is not nearly as important as simply recognizing that it does have enormous value and then trying to preserve this value and put it to good use’ (p. 280). Gallaway’s discussion of key night sky traits includes its ability to connect us to the natural world, its ability to engender a sense of wonder, and its beauty. Such an articulation of the value of reducing light pollution falls outside traditional economic calculations, as discussed elsewhere by Gallaway (2010 Gallaway, T. (2010). On light pollution, passive pleasures, and the instrumental value of beauty. Journal of Economic Issues, 44, 71–88.10.2753/JEI0021-3624440104[Taylor & Francis Online], [Web of Science ®] [Google Scholar]). It also further calls into question a needs-based approach. As a frame, light pollution will set the boundaries on what sort of answers are possible, which requires a careful consideration of how ‘needs’ are defined, and what needs ought to be encapsulated by future policies. About 1.7 billion people or more than a fifth of the world’s population are without access to electricity and modern lighting. The problem is most severe in rural areas or on the fringes of cities. , however the extent to rural electrification varies widely from country to country.  For example, 90% of Africa is not served by grid electricity versus 20% of Mexico. In fact, some African countries, for example, Rwanda and Burundi have barely passed the 1% electrification threshold! To place an attachment on a street light owned by us, you need to get a licence. Contact Highways England if the street light is on a motorway or an ‘A road’ they manage in England. The GravityLight Foundation aims to improve the lives of people without electricity by providing clean, safe and affordable lighting The anthropic principle is based on the observation that any small change in any of the basic constants of physics, which include the speed of light, would make human life impossible. hello, I have an infinix X557 the lcd backlight isn’t coming up but the screen display is ok. I would appreciate any diagram towards this We aim to fix streetlights within 28 working days. If it can’t be fixed on the first visit, we may need to order extra parts and the repair will be planned as soon as possible. Experts say that many drivers confuse the “service required” light on the gauge cluster for the Check Engine light. These warning lights are unrelated. The service required light just means the car is due for an oil change or other routine maintenance. It is not the indicator of trouble that the Check Engine light is. Street light switched off for energy saving CarMD published a list of the five most common Check Engine light codes in 2010 and estimated cost of repair. In order of frequency, they are: The problem with the last bulb is this; the dimmer switch itself needs to see a suitable load. i.e. it is happy working into a standard filament bulb. It’s driving all your lights in parallel, so whilst there is one regular bulb in there the dimmer is still happy. At the point you replace that last bulb with an LED lamp, the dimmer now sees only LED electronics as its load. The dimmer will not function properly (due to the way it works, it won’t fire correct) and the result is it sends occasional pulses to the lights in its confusion and you observe the flickering. Outages are usually repaired within five working days. If the fault is regarding the electricity supply to the light we inform the local electricity company who usually attend within eight working days of receiving report. The purpose of this paper is to elucidate light pollution as a normative concept, and focus specifically on its increasing role in shaping, or framing, future regulatory efforts, and decision-making processes. The goal is not to condemn or approve of the use of light pollution from an ethical perspective, nor is it to arrive at definitive answers for the ambiguities inherent in the concept. Rather, I begin by accepting the term as the dominant concept for describing a novel environmental problem, and critically reflect on its ethical significance and potential limitations. While the implications of light pollution are far-reaching, here I will focus specifically on light pollution as it relates to urban nighttime lighting. Such an analysis can be seen as an example of an issue discussed within this journal by Elliott (2009 Elliott, K. (2009). The ethical significance of language in the environmental sciences: Case studies from pollution research. Ethics, Place & Environment, 12, 157–173.10.1080/13668790902863382[Taylor & Francis Online] [Google Scholar]), namely the ethical significance of language and terminology choices for framing environmental policy decisions and debates. While Elliott discusses very different types of pollution, the themes highlighted are quite relevant for an examination of light pollution. Elliott—who draws from a more pragmatic branch of environmental ethics that I adopt here—describes the usefulness of practical ethics for policy discussions. Philosophers can help to create and define the moral space within which policy decisions will be made, and so can contribute to upstream policy decisions. Elliot (2009 Elliott, K. (2009).
