The use of full cutoff fixtures can allow for lower wattage lamps to be used in the fixtures, producing the same or sometimes a better effect, due to being more carefully controlled. In every lighting system, some sky glow also results from light reflected from the ground. This reflection can be reduced, however, by being careful to use only the lowest wattage necessary for the lamp, and setting spacing between lights appropriately.[86] Assuring luminaire setback is greater than 90° from highly reflective surfaces also diminishes reflectance. A change in the speed of light would quite literally end the world as we know it. The speed of light is not an arbitrary speed with no effect on outside systems, but is in fact a component in one of the most fundamental equations in the universe[6], the equation for matter: E = mc2 where E is energy, m is mass, and c is the speed of light in a vacuum.[7] This means that any increase of the speed of light would in turn increase the amount of energy released by the reactions of matter. Because the Sun, or indeed any star, relies on the reactions of matter, most notably nuclear fusion, a change in the speed of light would alter its energy output; if light were traveling as fast as some creationists demand, then the energy output of the Sun could be expected to increase over 800,000,000 times.[8][9] The radical effect of the electric lightbulb cannot be overstated. More than any lighting technology that preceded it—candles, oil lamps, or gas lighting—the electric light revolutionized the night. Now the darkness, at least in cities, was in full retreat. 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. The blinding effect is caused in large part by reduced contrast due to light scattering in the eye by excessive brightness, or to reflection of light from dark areas in the field of vision, with luminance similar to the background luminance. This kind of glare is a particular instance of disability glare, called veiling glare. (This is not the same as loss of accommodation of night vision which is caused by the direct effect of the light itself on the eye.) A street light fault is classed as an emergency if the light’s wires are exposed, if the shade is broken or hanging off or if the problem is caused by a road traffic accident.  If you think the problem is an emergency, please call Contact Warrington on 01925 443322 and the team will aim to inspect the light within two hours. Unfortunately, research is showing that in the U.S.A. fully two-thirds of us live under skies so bright we have lost the view of the Milky Way. And this loss comes mostly from just plain bad lighting – lighting that is not even doing a good job of showing us things we need or want to see on the ground. 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. Our Alternative is GravityLight – an innovative device that generates light with the lift of a weight Lights on tall structures can disorient migrating birds. Estimates by the U.S. Fish and Wildlife Service of the number of birds killed after being attracted to tall towers range from 4 to 5 million per year to an order of magnitude higher.[65] The Fatal Light Awareness Program (FLAP) works with building owners in Toronto, Ontario, Canada and other cities to reduce mortality of birds by turning out lights during migration periods. The starlight problem states that if the universe was only 6,000 years old — as Biblical literalism and Young Earth Creationism (YEC) state — then there would not be sufficient time for distant starlight to reach Earth. We can see light from stars more (way more) than 6,000 light years away, therefore the universe cannot be a mere 6,000 years old. The City of Winnipeg has adopted the latest Transportation Association of Canada’s Street Lighting Design Guide that stipulates the light levels for the City’s streets. This is the criteria that defines the number of lights and the wattage used to illuminate City streets. The main purpose of street lighting is to “provide an adequate visual environment for road users to safely use the road system during hours of darkness.” I spent more than 30 years looking for a solution to the light travel time problem, and recently I began thinking about a possibility that I find satisfactory. With so many other proposed solutions, one may legitimately ask why one more? I see that most of these solutions to the light travel time problem have advantages and disadvantages. If there were one solution that worked, there would not be so many solutions, and there would not be such sharp disagreement. Please consider my modest proposal. As I have previously argued (Faulkner 1999), I submit that God’s work of making the astronomical bodies on Day Four involved an act not of creating them ex nihilo, but rather of forming them from previously-created material, namely, material created on Day One. As a part of God’s formative work, light from the astronomical bodies was miraculously made to “shoot” its way to the earth at an abnormally accelerated rate in order to fulfill their function of serving to indicate signs, seasons, days, and years. I emphasize that my proposal differs from cdk in that no physical mechanism is invoked, it is likely space itself that has rapidly moved, and that the speed of light since Creation Week has been what is today. An English journal has become alarmed at the relation of electricity to songbirds, which it maintains is closer than that of cats and fodder crops. How many of us, it asks, foresee that electricity may extirpate the songbird?…With the exception of the finches, all the English songbirds may be said to be insectivorous, and their diet consists chiefly of vast numbers of very small insects which they collect from the grass and herbs before the dew is dry. As the electric light is finding its way for street illumination into the country parts of England, these poor winged atoms are slain by thousands at each light every warm summer evening….The fear is expressed, that when England is lighted from one end to the other with electricity the song birds will die out from the failure of their food supply.[77] Nicholas Nickleby was a campaigning novel highlighting the brutality of these schools to an ignorant or compliant society, which ultimately resulted in the schools’ demise. Today, Dotheboys Hall is filled with children being children, innocent fun and mischief, blissfully ignorant of Dotheboys’ past. The parallels between Nicholas Nickleby and modern-day campaigning journalism should not be lost. Sean Webb Dotheboys Hall Bowes, Co Durham Because of the increased sensitivity of the human eye to blue and green wavelengths when viewing low-luminances (the Purkinje effect) in the night sky, different sources produce dramatically different amounts of visible skyglow from the same amount of light sent into the atmosphere. Streetlight – An outdoor light, usually supported by a lamppost or pole, for illuminating a street, road or public area. Streetlight – This is a form to report a single streetlight issue. If there is a problem with the electricity supply, we will need to inform the electricity supplier and could take more time to fix the light. 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.
