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] 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 Nighttime illumination, once scarce, is now possessed in abundance and unavoidably ubiquitous. As a result, though, an interrelated shift in perception and valuation emerged—a shift that is critical to present discourse. With this abundance and ubiquity, a renewed attention was given to what is hindered by light. Darkness became, as Hasenöhrl notes, a valorized and ‘sought-after luxury’ of our electrified nights (2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar], p. 119). As a result, our taken-for-granted infrastructure of artificial nighttime lighting has been re-noticed, but in a new light. Concerns are increasingly articulated through a sense of loss—a loss of connection to starlight, or an aspect of nature, or the sublime, or a piece of our humanity—brought about by the loss of dark or ‘natural’ nights (e.g. Bogard, 2013 Bogard, P. (2013). The end of night: Searching for natural darkness in an age of artificial light. New York, NY: Back Bay Books. [Google Scholar]). Outdoor Area Light – An outdoor light, typically on private property, that is maintained by the electric company and leased to the customer. Column Number: Asset Id: Street: Included in part-time night lighting scheme: Known fault: Histories of nighttime illumination mainly focus on the seventeenth century onward, for a few reasons. First, lighting technologies remained essentially unchanged for thousands of years before then (Schivelbusch, 1988 Schivelbusch, W. (1988). Disenchanted night: The industrialization of light in the nineteenth century. (A. Davis, Trans.) London: University of California Press. [Google Scholar]). Second and relatedly, public lighting in the modern sense only emerged in the mid-1600s. This was a time of societal changes in Europe that allowed for lighting technologies and associated urban behaviors to rapidly develop.22. For a summary of these societal changes, see Ekirch’s At Day’s Close (2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar], p. 72).View all notes In considering the origins of public nighttime lighting in the seventeenth and eighteenth centuries, two important points should be noted. The first is that, despite technical improvements to oil lamps, lighting was still poor and city streets were mostly dark; only major thoroughfares were lit, and often only on the darkest nights of winter for a few hours (Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar]; Schivelbusch, 1988 Schivelbusch, W. (1988). Disenchanted night: The industrialization of light in the nineteenth century. (A. Davis, Trans.) London: University of California Press. [Google Scholar]). Second, old habits did not die easily; darkness still represented a time both sacred and dangerous for many. In certain places it remained custom to stay home, except for special occasions, and devote evenings to prayer and rest (Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar]). Use dimmer switches on household lights or use candles. At night, use dimmer switches in your home to reduce unnecessary lighting, or try using candles if you want to reduce your light pollution even further, and to encourage your own body’s winding down for the night. You might find that you like the effects, and appreciate the increased restful sleep of your entire family! Also, if possible, consider eliminating your use of electronics a couple of hours before you go to bed to eliminate the blue light that such devices often emanate that may negatively impact your body’s own melatonin production. Hi can someone help me! My flashlight won’t work.. anybody who had the same problem? If you are reporting problems with temporary traffic lights, please provide relevant contact details where possible. 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. 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. 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] Maxman Atlant Gel Atlant Gel Masculin Active Eron Plus Erozon Max Anabolic Rx24 Atlant Gel eracto Masculin Active
