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. 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. I identify a little-noticed issue in the normal formulation of the light travel time problem. In addition, I lay groundwork for the beginning of a new solution to the problem. This solution invokes similarity between creative acts of Day Four and other days of the Creation Week, but especially Day Three. The Day Three account suggests unusually fast growth for plants. In similar fashion, this possible new solution suggests unusually fast propagation of light on Day Four, probably by rapid expansion of space. This is an appeal to a miraculous event rather than a physical process to get distant starlight to the earth. It is not yet clear whether this suggestion could have testable predictions. If this is the correct way to look at the problem, it may be that we are seeing much of the universe in something close to real time. I briefly compare this possible solution to the light travel time to other previously published proposals. 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. Deciphering the Code Do-it-yourselfers can buy inexpensive code readers that connect to this standardized onboard diagnostics (OBD) port and search for the code’s meaning on Web sites such as Engine Light Help. The Check Engine light can even be turned off by some code readers, even though this action alone does not actually repair the underlying problem. In many such cases the light will simply come back on later. Clarifications to the ambiguities discussed above will likely change alongside differences in geographies, cultures, and belief systems. The recent edited volume Cities of Light (Isenstadt et al., 2014 Isenstadt, S., Maile Petty, M., & Neumann, D. (Eds.). (2014). Cities of light: Two centuries of urban illumination. New York, NY: Taylor & Francis. [Google Scholar]) provides a first overview of historic developments in nighttime illumination with respect to individual cities, a format that could be expanded to contemporary environmental debates. But regardless, if light pollution will be the frame through which regulations are established, anticipating value-level conflicts and ambiguities is important. We must clarify—or at the least debate—the normative foundations of light pollution before the framework becomes normalized and fades into the background of presuppositions informing nighttime lighting strategies. Two switches are supposed to control one set of lights but don’t always work right. Occasionally a switch goes bad. More often this problem comes from someone having Replaced a switch wrongly. Please enter any additional information that may help our technician locate the light for repair. 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? 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. Please enter any additional information that may help our technician locate the light for repair. Not convinced that extra lighting is a problem? Check out these nighttime satellite views of Earth, courtesy of NASA’s Suomi NPP satellite. Additional images from Suomi NPP taken between 2010 and 2016 clearly show how light pollution is on the rise around the globe. Any scarcity of urban nighttime illumination was quickly diminishing as electrification spread across North American and Europe during the twentieth century, developing alongside urbanization and the growth of transportation networks (Isenstadt, 2014 Isenstadt, S. (2014). Good night. Places Journal. Retrieved 22 October, 2014, from[Crossref] [Google Scholar]). This proliferation of nighttime illumination has been continuous to the present day, save for two major disruptions: World War Two and the energy crisis of the 1970s. However, nighttime illumination efforts quickly resumed shortly after both of these events (Neumann, 2002b Neumann, D. (2002b). Architectural illumination since World War II. In D. Neumann (Ed.), Architecture of the night: The illuminated building (pp. 78–84). New York, NY: Prestel. [Google Scholar]). Current estimates are that artificial nighttime lighting continues to increase globally by about 3–6% annually (Hölker et al., 2010 Hölker, F., Moss, T., Griefahn, B., Kloas, W., Voigt, C., Henckel, D., … Tockner, K. (2010). The dark side of light: A transdisciplinary research agenda for light pollution policy. Ecology and Society, 15(4), 13.10.5751/ES-03685-150413[Crossref], [Web of Science ®] [Google Scholar]). This has been, in many ways, the ultimate realization of values strived for since the seventeenth century. A lengthening of the day has effectively been achieved, creating unmistakably modern nights where the various facets of nightlife can occur, and where many daytime activities can continue well into the night. But this has come with unintended consequences. In his exploration of ‘the world after dark’, Dewdney (2004 Dewdney, C. (2004). Acquainted with the night: Excursions through the world after dark. Toronto: HarperCollins Publishers Ltd. [Google Scholar], p. 101) cleverly evaluates the two-sided nature of this achievement, stating, In light of this disagreement, it is safe to say that the horizon problem has not been decisively solved. According study conducted by CarMD, five common malfunctions cause the check engine light to come on, and several of them are simple to fix yourself. Let’s take a look at the most common issues. Recent creationists believe that the universe is only thousands of years old. The universe appears to be far larger than just a few thousand light years in size, suggesting the light travel time problem. However, by concentrating on the current age of the universe, we incorrectly formulate the light travel time problem. I recommend that we properly state the problem by noting that Adam had to see much of the universe at the conclusion of the Creation Week. Disputes are still common when deciding appropriate action; and differences in opinion over what light is considered reasonable, and who should be responsible, mean that negotiation must sometimes take place between parties. Where objective measurement is desired, light levels can be quantified by field measurement or mathematical modeling, with results typically displayed as an isophote map or light contour map. Authorities have also taken a variety of measures for dealing with light pollution, depending on the interests, beliefs and understandings of the society involved.[citation needed] Measures range from doing nothing at all, to implementing strict laws and regulations about how lights may be installed and used. 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. 8. Gallaway et al.

These criteria ‘consider the night sky polluted when the artificial brightness of the sky is greater than 10% of the natural sky brightness above 45° of elevation’ (Gallaway et al., 2010 Gallaway, T., Olsen, R., & Mitchell, D.
