Desirability of street lights

A variety of studies have supported this view but at least one indicated that it had little or no effect.

References should be given. This phrase seems not neutral, giving importance to just "one article". How many studies have ben carried out? One in three is significant, but one in a hundred deserves no reference to it. --John C PI 14:58, 8 January 2006 (UTC)[reply]

I googled around for these studies but couldn't find any. I took the liberty of removing this section of the article myself. --Matt0401 18:57, 26 March 2006 (UTC)[reply]

It is no longer true that Britain has almost exclusively Sodium lighting. It is now becoming rare in many areas! Dbfirs (talk) 23:58, 2 January 2008 (UTC)[reply]

Inconsistency

Some other web page in Wikipedia claims that Paris in France had some electric street lamps in 1878.

Paris being in Europe; that would make it the first European city to have street lights.

It was demonstrated but wasn't placed into production as a street lamp. Binarypower 16:42, 3 September 2006 (UTC)[reply]

"The next challenges"/"The future"

To me, that section seems out of place, somewhat biased, and totally unsourced. My initial instinct was to remove it, however I don't want to destroy what looks like good faith work with (I hope) good info in it. Anyone else have advices or something on that section?

The whole calculation section of CO2 emmissions is completely unsourced and untrue. An average incandecent bulb may be 150 (I would personally say lower), however, later int the section it mentions lamps at 5 and 20 watts. Also, street lighting contributes to less than 3% of the power consumed by the city. In the power shortage of the 80s, Las Vegas ordered all neon-lighting to be turned off. In turn, savings of 3% were made, so this is hardly worth mentioning as a major polluter of CO2. In my opinion, I think recalculating it with 20 volt streetlights, and comparing the kWhs consumed to another energy consumer, eg: Air Conditioning. Architect2k 17:24, 11 September 2006 (UTC)[reply]

Reads like original research to me, I was going to comment on it right when I read it.. Reads like.. somebody lobbying for change or something. --Streaky 17:48, 27 November 2006 (UTC)[reply]

Studies in Denmark for systems with electronic ballasts communicating through power line communication to the cabinet has shown that the ROI is around 9-10 years if applied to an existing street light system. In Denmark you will need 2 people and a lift for installing the electronic ballast to the fixture and with the cost of the equipment and an expected lifetime for electronic equipment in this environment, this doesn't make the solution feasible.

First city

According to this, the first city in the world to be lit by electric streetlamps was Cleveland, Ohio, in 1879. Uncle G 09:46, 7 October 2006 (UTC)[reply]

Looks like your correct from these sources too. Binarypower 03:06, 9 October 2006 (UTC)[reply]
Acoording to [1], Paris was using arc lamps in 1877 (the text is in black on black) —Preceding unsigned comment added by 201.73.148.130 (talk) 18:06, 10 December 2007 (UTC)[reply]

Distance

is there any maximum distance streetlights can be place away from each other, I would assume so as their effectivness with diminish the further away from each other they were placed. I was bored last ngiht and figured out they were roughly 30m apart from each other either on the smae side of the road of alternating from one side to the other —The preceding unsigned comment was added by Patcore (talk • contribs) 10:41, 12 March 2007 (UTC).[reply]

Manufacturers

Shouldn't there be such a section in this article? Possible entries are: AEG, GE (USA), Siemens (Germany), Svetlina (Stara Zagora, Bulgaria) etc. Kaksisi 18:48, 6 September 2007 (UTC)[reply]

Grim light

Sorry for making this peaceful article a bit horrendous, but the additions still belong there, that was a part of history. 91.83.28.101 (talk) 13:38, 19 April 2008 (UTC)[reply]

Someone purged the article, which is equal to censorship. Like it or not lamp posts were and are frequently used as makeshift gallows in mob executions and the paragraph I added included several example, yet some jerk swiftly removed as unsourced. This is equal to censorship! 91.83.16.172 (talk) 22:40, 10 May 2008 (UTC)[reply]
