Lighting is responsible for one-fourth of all electricity consumption worldwide,[citation needed] and case studies have shown that several forms of over-illumination constitute energy wastage, including non-beneficial upward direction of night-time lighting. In 2007, Terna, the company responsible for managing electricity flow in Italy, reported a saving of 645.2 million kWh in electricity consumption during the daylight savings period from April to October. It attributes this saving to the delayed need for artificial lighting during the evenings. A typical kerosene lamp is made by taking an empty bottle or tin can, putting a wick in the middle, filling it with fuel and lighting. Using kerosene for lighting is extremely inefficient, dangerous and expensive, and it has extensive health and environmental drawbacks. Light pollution is artificial light introduced into the natural night, especially where it is not needed or wanted. This unwanted light appears “The customer is really, in the long run, potentially hurting their pocketbook by leaving that light on and ignoring it,” says Jim Collins, a national training team leader for Ford Motor Co. In some extreme cases, the car’s computer may reduce power for you as it tries to limit the risk of damage. You can report problems with street lights or illuminated signs on council-maintained roads and footpaths (public highway) to the council. You can report a fault online or by telephone. Hi can someone help me! My flashlight won’t work.. anybody who had the same problem? 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). In the 1600s, Ole Roemer became one of the first scientists to make a measurement of the speed of light. Roemer observed the orbits of Jupiter’s nearest moon and recognized that its orbital period was observed to be approximately 22 minutes longer when measured from Earth when it was furthest from Jupiter compared to when it was closest to Jupiter. Roemer reasoned that the difference was due to the fact that it took longer for light from Jupiter to travel the extra distance when Earth’s position was on the opposite side of the Sun from Jupiter. The distance d2 is 2.98×1011 m greater than the distance d1. Determine Roemer’s estimate of the speed of light in the 1600s. Medical research on the effects of excessive light on the human body suggests that a variety of adverse health effects may be caused by light pollution or excessive light exposure, and some lighting design textbooks[34] use human health as an explicit criterion for proper interior lighting. Health effects of over-illumination or improper spectral composition of light may include: increased headache incidence, worker fatigue, medically defined stress, decrease in sexual function and increase in anxiety.[35][36][37][38] Likewise, animal models have been studied demonstrating unavoidable light to produce adverse effect on mood and anxiety.[39] For those who need to be awake at night, light at night also has an acute effect on alertness and mood.[40] To report a streetlight that’s out or malfunctioning, complete the form below (*Required). If you are reporting problems with temporary traffic lights, please provide relevant contact details where possible. Use the street light outage application to report street light outages. The application allows you to select a street light on a map to report lights out, lights flickering, and lights that are burning during the day. 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. Many astronomers request that nearby communities use low pressure sodium lights or amber Aluminium gallium indium phosphide LED as much as possible, because the principal wavelength emitted is comparably easy to work around or in rare cases filter out.[90] The low cost of operating sodium lights is another feature. In 1980, for example, San Jose, California, replaced all street lamps with low pressure sodium lamps, whose light is easier for nearby Lick Observatory to filter out. Similar programs are now in place in Arizona and Hawaii. Such yellow light sources also have significantly less visual skyglow impact,[91] so reduce visual sky brightness and improve star visibility for everyone. Setterfield, B. 1989. The atomic constants in light of criticism. Creation Research Society Quarterly 25:190–197. The big bang model assumes that the universe is many billions of years old. While this timescale is sufficient for light to travel from distant galaxies to earth, it does not provide enough time for light to travel from one side of the visible universe to the other. At the time the light was emitted, supposedly 300,000 years after the big bang, space already had a uniform temperature over a range at least ten times larger than the distance that light could have travelled (called the ‘horizon’)11 So, how can these regions look the same, i.e. have the same temperature? How can one side of the visible universe ‘know’ about the other side if there has not been enough time for the information to be exchanged? This is called the ‘horizon problem’.12 Secular astronomers have proposed many possible solutions to it, but no satisfactory one has emerged to date (see Attempts to overcome the big bang’s ‘light-travel–time problem’). Display light issue isn’t that big, as you would still be able to operate your phone, but you are surely going to encounter a whole lot of troubles when it comes to your phone operation. If you are lucky enough then the first step will surely solve your problem and without paying anything to anyone, else it will become a huge problem from you. Requesting new street lights  Requests for new street lighting should be passed to the parish or town council with as much information as possible. We’re converting many of our street lights to energy-efficient Light Emitting Diode (LED) technology. Read more about our LED street lighting project. When reporting a lighting fault to us it would be helpful if you could supply: If you are reporting a hazardous condition (other than a malfunctioning light) DO NOT use this form. Please call 1-800-4OUTAGE (1-800-468-8243) to report the condition. The street lighting service looks after over 22, 000 street lights and illuminated traffic signs. In addition, many homes have poor ventilation and fuel-based lighting poses serious debilitating health hazards such as respiratory and eye problems. In developing nations, acute respiratory infection, influenza and pneumonia kill nearly two million children annually. In September 2009, the 9th European Dark-Sky Symposium in Armagh, Northern Ireland had a session on the environmental effects of light at night (LAN). It dealt with bats, turtles, the “hidden” harms of LAN, and many other topics.[76] The environmental effects of LAN were mentioned as early as 1897, in a Los Angeles Times article.
