Measuring the effect of sky glow on a global scale is a complex procedure. The natural atmosphere is not completely dark, even in the absence of terrestrial sources of light and illumination from the Moon. This is caused by two main sources: airglow and scattered light. Energy consumption:Joshua Filmer of Futurism.com reported in 2013 that at least 30 percent of street lighting is wasted — light that shines up into the sky, where it does no good. “Calculations show that 22,000 gigawatt-hours a year are wasted. At $0.10 per kilowatt-hour, the cost of that wasted energy is $2.2 billion a year,” Filmer wrote. “That’s 3.6 tons of coal or 12.9 million barrels of oil wasted every year to produce this lost light.” Hi can someone help me! My flashlight won’t work.. anybody who had the same problem? You can report a non-urgent fault with a street light by using the ‘Report now’ button below or phoning the Fault Line on 0845 601 0939, Monday to Friday from 8am to 5pm.  To report a streetlight that’s out or malfunctioning, complete the form below (*Required). Report a street light problem  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. The challenge faced by 21st century policymakers is to provide outdoor light where and when it is needed while reducing costs, improving visibility, and minimizing any adverse effects on plants, animals, and humans caused through exposure to unnatural levels of light at night. (Kyba et al., 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], p. 1807) The Dark-Sky Association was started to reduce the light going up into the sky which reduces visibility of stars (see Skyglow below). This is any light which is emitted more than 90° above nadir. By limiting light at this 90° mark they have also reduced the light output in the 80–90° range which creates most of the light trespass issues. In certain cases an over-illumination lighting technique may be needed. For example, indirect lighting is often used to obtain a “softer” look, since hard direct lighting is generally found less desirable for certain surfaces, such as skin. The indirect lighting method is perceived as more cozy and suits bars, restaurants and living quarters. It is also possible to block the direct lighting effect by adding softening filters or other solutions, though intensity will be reduced. All of this can be traced to one thing: the curse of light pollution.  In another example, the city of Calgary has recently replaced most residential street lights with models that are comparably energy efficient.[98] The motivation is primarily operation cost and environmental conservation. The costs of installation are expected to be regained through energy savings within six to seven years. The two main reasons street lights stop working are: Multiple Streetlights – This is a form to report more than one streetlight issue for the same city/township. Column Number: Asset Id: Street: Included in part-time night lighting scheme: Known fault: ​Please help us by giving detailed information about the problem. For example, tell us if the light is out altogether, going on and off, burning all day or intermittent and include the number of the column if you can. If you can’t see this then please state the exact location or adjacent house number. U.S. federal agencies may also enforce standards and process complaints within their areas of jurisdiction.

Even dim light can interfere with a person’s circadian rhythm and melatonin secretion. A mere eight lux—a level of brightness exceeded by most table lamps and about twice that of a night light—has an effect, notes Stephen Lockley, a Harvard sleep researcher. Light at night is part of the reason so many people don’t get enough sleep, says Lockley, and researchers have linked short sleep to increased risk for depression, as well as diabetes and cardiovascular problems. Type of problem choose one Lights not operating Lights going on and off Lights on during the day Broken glass Open, broken, or missing light fixture Damaged poles Exposed wires Graffiti on street light poles Other To place an attachment on a street light owned by us, you need to get a licence. We will not fit a shade to new LED street lighting for the first 3 months after installation. If there is still an issue after 3 months, please report the problem. 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. Judging by the number of visible stars, my observations show that light pollution has made the night sky over Warrensburg, New York, about four times brighter since the mid-’70s. And at various points along the horizon, there are now small domes of light indicating the presence of nearby towns, the brightest of which is Lake George, a popular tourist center several miles to the south. The question is then whether there can be a meta-inductive method which is “predictively optimal” in the sense that following that method succeeds best in predictions among all competing methods, no matter what data is received. Gerhard Schurz has highlighted results from the regret-based learning framework of Cesa-Bianchi that there is a meta-inductive strategy that is predictively optimal among all predictive methods that are accessible to an epistemic agent (Cesa-Bianchi & Lugosi 2006; Schurz 2008, forthcoming). This meta-inductive strategy, which Schurz calls “wMI”, predicts a weighted average of the predictions of the accessible methods, where the weights are “attractivities”, which measure the difference between the method’s own success rate and the success rate of wMI. The fourth solution is that the speed of light has decreased since creation week (Norman and Setterfield 1987; Setterfield 1989). This is often called “cdk” for “c decay,” where “c” is the letter that physicists usually use to represent the speed of light. Undoubtedly, this solution has sparked the hottest debate amongst recent creationists. When the possibility that light might have decreased was first proposed in the creation literature three decades ago, it was immediately met with great interest. However, much of the early interest soon turned to opposition. Opponents do not believe that the data adequately support this hypothesis; supporters do. Opponents point out that any significant change in the speed of light would alter the structure of matter that ought to be visible in distant objects. Supporters agree, but argue that other factors have changed to compensate for this. There is a great divide on this solution, and we will not discuss this controversy anymore here.
