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. Over-illumination is the excessive use of light. Specifically within the United States, over-illumination is responsible for approximately two million barrels of oil per day in energy wasted.[citation needed] This is based upon U.S. consumption of equivalent of 18.8 million barrels per day (2,990,000 m3/d) of petroleum.[16] It is further noted in the same U.S. Department of Energy source that over 30% of all primary energy is consumed by commercial, industrial and residential sectors. Energy audits of existing buildings demonstrate that the lighting component of residential, commercial and industrial uses consumes about 20–40% of those land uses, variable with region and land use. (Residential use lighting consumes only 10–30% of the energy bill while commercial buildings’ major use is lighting.[17]) Thus lighting energy accounts for about four or five million barrels of oil (equivalent) per day. Again energy audit data demonstrates that about 30–60% of energy consumed in lighting is unneeded or gratuitous.[18] 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. Occasionally, the Check Engine light comes on when nothing is wrong with the car, Mazor says. It could be a temporary problem caused by a change in humidity or other factors. In such cases, the light should go off by itself after a short time. My instax camera fell about less than 1m height, and now the red light next to the viewing lens is not disappearing. Due to that, i cannot take photos when i press the button. Help? Akridge, G. R. 1984. The universe is bigger than 15.71 light years. Creation Research Society Quarterly 21, no. 1:18–22. 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. Dear Eng : Plis help me to repair tecno N6s lights by jumper The red light of camera wont turn off. What should i do? I changed the batteries. But the red light still on 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.” I just dropped my camera and now the red light isn’t going away please help me Hey. My camera also fell like a week ago and the red light near the lense won’t go and if I take a photo, the film won’t come out like if I didn’t had any. This paper has critically engaged with the concept of light pollution and identified areas that require further clarification. The limitation of light pollution as a criterion for the moral evaluation of artificial nighttime lighting was discussed, concluding that it can best function in the limited capacity of mitigation or preservation efforts. This led to practical concerns, specifically the ambiguity of thresholds for acceptable levels of light pollution, and the mechanisms that could be used to establish said thresholds. The intention was to highlight conceptual and practical issues that, if addressed, can help to strengthen future regulatory efforts in urban nighttime lighting. Jill is helping her younger brother Nathan set up an exhibit for a Science Fair. Nathan’s exhibit pertains to the wave-particle nature of light waves. He wishes to demonstrate the wave nature of light by displaying the two point interference pattern of red laser light (λ = 648 nm). Nathan has purchased a double slit slide from a science warehouse which has slits separated a distance of 0.125 mm. Nathan has asked Jill to determine the slide-to-screen distance which will result in a 2.0 cm separation between adjacent bright spots. What distance will result in this antinodal spacing? Light pollution, also known as photopollution, is the presence of anthropogenic light in the night environment. It is exacerbated by excessive, misdirected or obtrusive uses of light, but even carefully used light fundamentally alters natural conditions. As a major side-effect of urbanization, it is blamed for compromising health, disrupting ecosystems and spoiling aesthetic environments. 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. The physics of fluorescent lights can’t be changed, but coatings inside the bulbs can be so they produce a warmer, less blue light. LED lights are more efficient than fluorescent lights, but they also produce a fair amount of light in the blue spectrum. Richard Hansler, a light researcher at John Carroll University in Cleveland, notes that ordinary incandescent lights also produce some blue light, although less than most fluorescent lightbulbs. 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. Section 2 discusses the moral and political significance of framing problems, in relation to the novel environmental problem of excess artificial nighttime lighting in cities. Section 3 then analyzes the concept of light pollution in detail. Here, both the origins of the concept and its current manifestations are presented, in order to provide a more comprehensive understanding of light pollution. Section 4 returns to the question of how light pollution frames concerns and possible responses, and discusses two interrelated questions: the potential limitations of the concept as a normative or prescriptive tool, and the ambiguities and inconsistencies in its practical application that require clarification. Thus, first steps are taken in dissecting the ethical significance of the concept of light pollution and the role it can play in addressing the adverse effects of artificial nighttime lighting.
