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). Of course, it must be remembered that the aforementioned biblical references to the stretching of the heavens appear in poetic passages that are unlike the record of Day Four in Genesis 1:14–19, which bears all the markings of prose (Boyd 2005). Consequently, “stretching” in these instances may be a metaphorical device that refers to nothing more than the creation of the heavens in their expanse. In other words, the language employed is likely not specific enough to enlist as certain evidence for the defense of my view. Nevertheless, the language surely does not preclude the position I have advanced; indeed, if the text does intend to convey the idea of light travelling at an abnormally accelerated rate in order to reach the earth on Day Four (or, at the very latest, Day Six), then reference to God stretching out the heavens is quite appropriate. Disadvantages of low pressure sodium lighting are that fixtures must usually be larger than competing fixtures, and that color cannot be distinguished, due to its emitting principally a single wavelength of light (see security lighting). Due to the substantial size of the lamp, particularly in higher wattages such as 135 W and 180 W, control of light emissions from low pressure sodium luminaires is more difficult. For applications requiring more precise direction of light (such as narrow roadways) the native lamp efficacy advantage of this lamp type is decreased and may be entirely lost compared to high pressure sodium lamps. Allegations that this also leads to higher amounts of light pollution from luminaires running these lamps arise principally because of older luminaires with poor shielding, still widely in use in the UK and in some other locations. Modern low-pressure sodium fixtures with better optics and full shielding, and the decreased skyglow impacts of yellow light preserve the luminous efficacy advantage of low-pressure sodium and result in most cases is less energy consumption and less visible light pollution. Unfortunately, due to continued lack of accurate information,[92] many lighting professionals continue to disparage low-pressure sodium, contributing to its decreased acceptance and specification in lighting standards and therefore its use. Another disadvantage of low-pressure sodium lamps is that some people find the characteristic yellow light very displeasing aesthetically.[citation needed] hello, I have an infinix X557 the lcd backlight isn’t coming up but the screen display is ok.

Kaise thik kare A second important point is that by concentrating upon the very distant objects, the light travel time problem is not formulated properly, for the situation is far worse! Most treatments of the light travel time problem concentrate upon the question of how we can see objects more than 6,000 lt-yr away. Because most objects clearly visible to the naked eye are well within 6,000 lt-yr, they aren’t a problem in a recent creation. But while it is possible for us to see most of the naked eye stars and today, some millennia after the Creation Week, it would not have been possible for Adam to have seen any stars (other than the sun) for at least four years after his creation. The stars were made on Day Four, and Adam was made on Day Six. The nearest star after the sun is 4.3 lt-yr away, so Adam could not have seen even the closest star for more than four years, and then stars would have slowly winked in over the succeeding years. However, the stars could not have fulfilled their God ordained functions when Adam first saw them after Day Six. These functions include being used to mark seasons and the passage of time (we still do this today with the day, month, and year). The passage of the year and the seasons are reckoned by how the sun appears to move against the background stars as the earth orbits the sun. Absent these background stars, it would not be possible to determine the passage of the year and of the seasons. Therefore, to truly solve the light travel time problem, light from stars even a few light years away must have been visible only days after their creation (and it is likely that the light of all the astronomical objects reaching the earth today also reached the earth at this early time). Any realistic solution to the light travel time problem must explain how Adam could have seen any stars on the evening following Day Six. Once that issue is resolved, the light travel time problem for truly distant objects probably is solved as well. At any rate, we ought to properly formulate the light travel time problem in all discussions of this issue. Light pollution is a topic gaining importance and acceptance in environmental discourse. This concept provides a framework for categorizing the adverse effects of nighttime lighting, which advocacy groups and regulatory efforts are increasingly utilizing. However, the ethical significance of the concept has, thus far, received little critical reflection. In this paper, I analyze the moral implications of framing issues in nighttime lighting via the concept of light pollution. First, the moral and political importance of problem framing is discussed. Next, the origins and contemporary understandings of light pollution are presented. Finally, the normative limitations and practical ambiguities of light pollution are discussed, with the aim of strengthening the framework through which decisions about urban nighttime lighting strategies are increasingly approached. For a long time, solution two was very popular, and while it is less popular today, it continues to have a wide following (the late Henry M. Morris, Jr. was fond of this solution). Proponents argue that by its very nature, creation must include some “appearance of age,” for plants, animals, and people were not made as embryos or infants, but as mature adults, even though they did not go through the normal process of growth to reach adulthood. We certainly see this is true of Adam and Eve, but it also would seem to be true of plants, or else they could not fulfill their God ordained purpose of providing food only 2–3 days after they appeared if they were not mature (Genesis 1:29–30). Similar reasoning applies to many animals. Thus, the stars could not fulfill their purposes unless they were visible right away, so God made them with their light already en route to earth. This has a certain amount of appeal to it, but it also could be construed as deceptive on the part of God to make light containing tremendous amount of information of physical processes that never happened. Since the vast majority of the universe is more than a few thousand light years distant, it would seem that we will never see light that actually left these distant objects, and hence much of the universe amounts to an illusion. This concern has been the primary motivation of those seeking other solutions to the light travel time problem. A full cutoff fixture, when correctly installed, reduces the chance for light to escape above the plane of the horizontal. Light released above the horizontal may sometimes be lighting an intended target, but often serves no purpose. When it enters into the atmosphere, light contributes to sky glow. Some governments and organizations are now considering, or have already implemented, full cutoff fixtures in street lamps and stadium lighting.
