New York City To Get LED Street Lighting
New York City’s Department of Transportation has tapped the Office for Visual Interaction for testing LED street lighting around the Big Apple. If successful, all of the city’s 300,000 street lamps could one day be made up of LEDs.
Of course, LEDs are just plain awesome! Their power consumption is much lower than that of standard bulbs. Heck, even lower than that of CFLs.
But the OVI contract doesn’t only replace the current high-pressure sodium lighting, but also introduces a whole new lamp pole as well. While I am a fan of LEDs, I am quite fond of the Gotham-styled lamp poles. Keep your paws off, OVI!
Okay, maybe the new poles aren’t so bad. The poles will be between four to six feet, and have up to 100 LEDs each. They will have four light sources per pole, and can create different light patterns. The light footprints can be tailored for parks, street corners or mid-block.
The city will begin testing with a mere six poles, and the testing period will end by fall of 2009. But even if the city approves the highly-efficient lamps, it’s likely they won’t roll out 300-thousand new lamp poles all at once.

全球变暖是个事实，原因很多而且人们都已经很清楚了。但为什么就不采取行动呢，无视破坏环境的行为存在。从根本上说，加强对市民的教育很有必要。
Global warming is a fact,there are numerous reasons and almost all the citizens know them.Why not take actions?why we keep turning a blind eye on them?It is essencial to enhence education to citizens!
I’m a chinese girl,I’m fairly concerened our environment.
OVI got the contract - what lighting company actually makes the LEDs?
This only a test, I repeat, only a test. Lets see what kind of results the OVI gets.
Yeah, that’s what New York really needs? I’m a believer in more efficient energy saving methods but please stop all the global warming madness, it snowed in Las Vegas and New Orleans this year! The democrats really got this global warming thing cornered, if its to hot it’s global warming and if its to cold then it’s must be global warming. How about the realization that the earth has natural weather cycles and was once a frozen tundra millions of years ago. Global weather patterns are going to change regardless of what man does or doesn’t. I’m not saying we shouldn’t promote efforts to keep mother earth clean but please stop all the global warming fear mongering.
Before anyone shows his or her ignorance again, let’s get one thing straight. THE ONLY ’scientists looking at facts’ that support global warming are those among us that have ‘agendas’ based on who commissioned or financed said fact finding mission. Also, he media is so biased it is truly unbelievable. The media gets money and ratings to ‘ scare’ the ignorant sheep and will look for so called ‘experts’ to back up this. Believe it or not, amongst our professional circles this global warming terrorism campaign unleashed by governments and the media s a big joke. In the end it is a cash grab that, unfortunately , is sucking in the ignorant at an alarming rate. Also, the vast majority of unbiased climatologists and ecologists, say there is ZERO global warming. The earth goes through climatic changes that vary. It has been going on since the absolute beginning of this planet. -So you get some real facts to bring to the party or shut up.
As far as the LED lights are concerned, they are a good idea IN THE SOUTH. Here in Toronto, the LED stop lights are a big hit, in the warmer months that is. When it starts snowing, they do not generate enough heat to keep the ice and snow off the lens so it does not work that great.

“The poles will be between four to six feet”
I fail to understand, apart, high. Poles are set about 60 feet apart and light units are about 20 feet above the roadway.
Of course being LED’s maybe 4 to 6 is correct.
Maybe the should look into induction lighting, as it seems that for street lighting it might be the way to go.

Global warming is real, is it man-made? Not completely.
The “facts” state that the Earth is experiencing an increase in the Average Global Temperature. This changes certain weather patterns, and yes Global Warming can result in snow in some places. It’s about the Earth’s Average Global Temperature, not the specific temperature in Las Vagas.
Another fact is large amounts of CO2 in the atmosphere contributes to warmer temperatures. Want proof? Look at at Mercury and Venus. Mercury is 46 - 70 million Kilometers from the sun with a 42% Oxygen atmosphere and trace amounts of Carbon Dioxide. It’s average temperature is ~350°C. Venus, on the other hand, is 108 million kilometers from the sun with a 96.3% Carbon Dioxide atmosphere. It’s average temperature is ~461°C.
So, with more CO2 comes higher temps. SO yes Humans are contributing to Global Warming, but we are hardly the only cause. We SHOULD work towards greener energy, if for no other reason then it is sustainable. We wont have gasoline for ever, Fossil Fuels are limited: the Sun, seed oils, wind, etc. are renewable and produce little to no CO2 emissions.

LEDs are just not ready for a full scale deployment yet. The MOST efficient LEDs still only reliably put out around 70 lumens per watt. While the 50 year old High Pressure Sodium technology achieves 100 lumens per watt. If you want to keep the same light levels as before (highly recommended!), you will actually need to burn MORE energy with LEDs. Where is the energy savings???? And don’t give me that Scotopic vs. Photopic BS.
