1. Remove the liberal bias from the article. Oh wait, you wouldn't have an article without that...
* ya, I live in Las Vegas, so i know what you mean. But I'm also an amatuer astronomer, so I get away at least once a year.


:Reality has a liberal bias. Not necessarily for things that only affect relations between humans (whether kookoo anarchists should let legal heroin stores open in front of schools or not, is Hamas evil..) but definitely for environmental things. The conservative track record is very bad on that. And don't say liberal is tree hugging people that want no wood to be used ever and think the tree's spirit speaks to them, the average liberal's nothing like that.

"really semi-barbaric densely populated areas of the United States" -- that's supposed to be NPOV?!

== FAC? ==

Just came across this article and it's looking great! ] seems to have done a great job making this into a very good piece of work. I'd love to nominate this as a ], but I know there's one thing that might hold it back - references. If someone could add this one missing section (perhaps by rearranging the External links section) then I reckon it could become featured. ] ] 23:02, 27 May 2005 (UTC)
:Thanks, that's very flattering and I agree with you about the references. (So far I've been lazy, since a lot of the info that I've added has been coming from recollections of my own experience.) I'll look at improving them over the next few days to help back up the information. I also still feel that it's not quite complete yet, and it trails off a bit towards the end. In particular, there's quite a bit more that might be said about the methods of reducing light pollution. If anyone wants to help fill that in, the door's open. Otherwise I'll see what I can do. ] 01:41, 28 May 2005 (UTC)

== More pictures ==

I don't know if anyone's following the edits I've been making lately. If you are, though, can anyone provide an extra image or two for inclusion in the article? In particular, I've been looking around for a good picture of something like a drop-lens cobra fixture, taken during the day, to demonstrate how it's designed in such a way so that light will escape horizontally and upwards. Any other images that might demonstrate things in the article would be great too, of course.


==Wiki Education assignment: BioEE1610 WIM==
I'd thought there might be free-to-use pictures available from the IDA, but it seems to want to charge even to obtain them, let alone re-publish.

I was on the boad of Dark Sky when this was changes. The reason is that old definition was biased by the industry and was incoherent of other definitions of pollution. Like the pollutants on the "1979 convention on long -range transboundary air pollution", where clearly, is included the light pollution.

:''"According to a study performed by ] magazine, ], ] has the least amount of light pollution, and thererefore the darkest skies in the continental United States."''
I've just (temporarily) removed the above paragraph from the ''Consequences/Loss of night sky'' section, because it doesn't seem to fit there when I read it. It doesn't seem like a consequence to me. I'm not sure exactly which section it should go into as they are right now. It might be that the article needs a new section for the current state of light pollution in different parts of the world, or something like that, but if so it'd be nice to have a bit more information stated than a line about Utah in the USA. Hopefully it can be cited a bit more specifically soon, too -- I've contacted ] to ask about where it came from. Does anyone have any thoughts? ] 10:54, 17 July 2005 (UTC)

regarding your statement about Alaska, my assumption with that is the fact that it stays dark for about 3 or 4 hours in the summer up there. The sun doesn't set until about 11:00pm up there in the summer. When it does set, its more like a perpetual twilight rather than complete darkness. ] 00:58, August 8, 2005 (UTC)

To-do list for Light pollution: edit·history·watch·refresh· Updated 2008-09-05

  • It is inaccurate in "Measurement of light pollution and Global Effects" section to say that work by Cinzano et al. "measures" the sky glow by using DMSP observations - this discussion should be corrected to say that this work provides a crude estimate using a model, and only of the zenith. For example, it uses sea-level atmospheric conditions everywhere, which cannot give accurate results in western US nor in aerosol-laden areas. Further, the photometric accuracy of the DMSP data has not been established and has been questioned in the refereed literature. Since someone else wrote this section, I will let them revise unless I am asked to do so. Cluginbuhl (talk) 23:03, 22 February 2008 (UTC)
      • There is a specific organization that suppress any efforts to give Italy a unique national bill against light pollution, which is Ente Nazionale di Unificazione, founded in the early years of 1900 to standardize industrial testing, materials, procedures and so on.

Its members are universities, public administrations, representatives of manifacturing industries and so on. It produced a specific standard UNI 10819 to (very theoretically) protect the sky from light pollution and some lectures to defend it against the hordes of people that recognized how that standard LEGALIZED light pollution rather than reduce it, but if every one agree I can try to translate their thoughts. To point out how scientists can vary their opinions about this topic it could be useful to summarize prof Zichichi article on catholic magazine "Famiglia Cristiana" and the remarks of prof Maffei, an italian astronomer who pionereed infrared photografic surveys to Zichichi's article. Again, I can traslate. As a final suggestion based on my own experience in Italy I have to remark that the "dispute" about light pollution depends on the strong relationship that links light and energy industries, universities, politicians. Light and energy industries are trying to increase profits and do not accept any regulamentation, universities have to defend their own business and do not like that someone else discovers and applies cheaper and environmental safe lighting rules, politicians fear to lose a powerful argument to gain votes, summarized as "daylight intensity lighting for safety against crime". But I have to remark that only 7 1/2 italian regions on 20, 40% of land and 30% of population have to bear "industrial" lighting rules: in 2007 Liguria, Friuli Venezia Giulia and half of Trentino Alto Adige rejected UNI standards to adopt "zero lighting above lamps" rules. How can exist a "dispute" about light pollution when the majority of a nation says that night skies have to be protected ? --195.210.65.30 (talk) 08:30, 12 December 2007 (UTC)

  • Check that references are formatted properly, both in the references list and in the article. Seems to be done now. Izogi 03:35, 30 May 2006 (UTC)
  • Expand the table of luminaires in the Adjusting types of lighting section.
    • This list is based on data in the IDA Information Sheet 52, which still needs to be cited.
      • For the record, that particular IDA information sheet might not be a reliable source... see this discussion. Izogi 23:54, 19 July 2005 (UTC)
        • i tend to agree with izogi and question the validity of this as a source Anlace 22:45, 25 February 2006 (UTC)
  • Expand the Organisations section so that it explains a bit about the formation of various organisations, instead of just listing a couple.
    • It might be useful to include a lighting engineering organisation or two, if there are any prominent ones.
    • Are there any well known organisations that actively counter what anti-LP campaigners say? If so, it's probably worth mentioning them to maintain a neutral point of view.
  • Add a more specific citation for the information in Interruption of the eco-system which refers to Michael Mesure's comments about the deaths of millions of birds. (Although I don't doubt he's said it, I couldn't find a reference, myself -- Izogi) Well tidied up by a helpful anonymous user—Thanks heaps. Izogi 10:23, 14 July 2005 (UTC)
  • Some of the text in the Types of light pollution section might actually belong in the Consequences of light pollution section, or maybe not.
  • Consider expanding the section about Redesigning lighting plans, or perhaps merge it into other sections. It seems a bit short right now. Done. Izogi 03:19, 11 July 2005 (UTC)
    • Should the paragraph about Calgary be moved to this section? Done. Izogi 03:19, 11 July 2005 (UTC)
  • Maybe think about adding a section to do with the current state of light pollution around the world. (Don't know how this would work, but the text about Utah having the least LP in the US doesn't seem to fit well in the Consequences of light pollution section.) Thoughts? Izogi 8 July 2005 07:01 (UTC)
  • Note something about pollution of the radio spectrum. (This may actually warrant its own article, but it should at least be cited here.) Izogi Added a disambiguation page and (for now) linked it to a radio spectrum pollution stub. Izogi 05:45, 18 July 2005 (UTC)
  • Establish better link to Lighting article and to energy conservation in generalAnlace 17:50, 19 February 2006 (UTC)

To-do list

Here's a list of possible things that the article might benefit from, in no particular order:


1. Remove the liberal bias from the article. Oh wait, you wouldn't have an article without that...

Reality has a liberal bias. Not necessarily for things that only affect relations between humans (whether kookoo anarchists should let legal heroin stores open in front of schools or not, is Hamas evil..) but definitely for environmental things. The conservative track record is very bad on that. And don't say liberal is tree hugging people that want no wood to be used ever and think the tree's spirit speaks to them, the average liberal's nothing like that.

Feel welcome to edit the list, of course. Izogi 23:55, 10 Jun 2005 (UTC)
