If an outdoor lighting pole is broken, please call Xcel Energy Customer Care at 1-800-895-4999. (Except in Minnesota; continue form submission) Stray light, in the sky or elsewhere, is wasted light – it is not needed for and does not help visibility. It is really a mistake that it is there. Why does it happen? Column Number: Asset Id: Street: Included in part-time night lighting scheme: Known fault: A study presented at the American Geophysical Union meeting in San Francisco found that light pollution destroys nitrate radicals thus preventing the normal night time reduction of atmospheric smog produced by fumes emitted from cars and factories.[82][83] The study was presented by Harald Stark from the National Oceanic and Atmospheric Administration. 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. If you notice a street light that is not operating properly, and it is not due to an emergency circumstance (i.e. flooding, downed power line, earthquake, etc.), please use the form below to report the problem. Our team of Customer Care Agents will respond to your email in the order received, Monday through Friday. Unexpected high volumes may result in a delayed response. 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). If the lightbulb flickers, follow this troubleshooting procedure: You’re driving home from work one day when the car owner’s worst nightmare happens: the check engine light pops on. It comes without warning and with no explanation. For most drivers, this means a trip to the mechanic, but it’s not difficult to diagnose (and sometimes fix) yourself. While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours). As Jalopnik recently pointed out, the check engine light is one of the most frustrating and confusing facets of owning a vehicle. It’s just a light with no information telling you what the problem is. It’s a cry from a baby with no explanation. But you can do a few things yourself before heading into the shop for costly repairs. Call it the most misunderstood indicator on your dashboard: The check engine light can mean many different things, from a loose gas cap to a seriously misfiring engine. Light trespass occurs when unwanted light enters one’s property, for instance, by shining over a neighbor’s fence. A common light trespass problem occurs when a strong light enters the window of one’s home from the outside, causing problems such as sleep deprivation. A number of cities in the U.S. have developed standards for outdoor lighting to protect the rights of their citizens against light trespass. To assist them, the International Dark-Sky Association has developed a set of model lighting ordinances.[12] In a large house there is a basement with three rooms. In the middle of each room is a light. There are no windows in any of the rooms and no light switches. 6. 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. Street lights on red routes, however, are maintained by Transport for London (TfL) – report a problem to TfL. 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. Some studies suggest a link between exposure to light at night, such as working the night shift, to some types of cancer, diabetes, heart disease, and obesity. That’s not proof that nighttime light exposure causes these conditions; nor is it clear why it could be bad for us. But we do know that exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms, and there’s some experimental evidence (it’s very preliminary) that lower melatonin levels might explain the association with cancer. If the light has one of the following faults please call 01443 425001 during the hours of 8:30am – 5:00pm or 01443 425011 during evenings and weekends. Hi can someone help me! My flashlight won’t work.. anybody who had the same problem? In our living room, there are 4 light sources, each of which consists of 4 light bulbs. I assume all of those (16 in total) light bulbs are in parallel, because when one of them is broken, all the others (15 bulbs), still shine. We can turn those light bulbs on with a slider. So it is possible to let them shine on f.i. half the intensity. Akridge, G. R. 1984. The universe is bigger than 15.71 light years. Creation Research Society Quarterly 21, no. 1:18–22. The ‘distant starlight problem’ is sometimes used as an argument against biblical creation. People who believe in billions of years often claim that light from the most distant galaxies could not possibly reach earth in only 6,000 years. However, the light-travel–time argument cannot be used to reject the Bible in favour of the big bang, with its billions of years. This is because the big bang model also has a light-travel–time problem. 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 [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. Journal of Economic Issues, 44, 71–88.10.2753/JEI0021-3624440104[Taylor & Francis Online], [Web of Science ®] [Google Scholar], p. 72). erogan VigRX Plus Tonus Fortis Penigen 500 el macho Maca peruana BeMass Maca peruana Tonus Fortis Stéroïdes
