:o, I don't know why I haven't heard of this yet, but this is nice. Really, it's a classic example of the business case for sustainability. Nice post.

I was suprised to see on the TreeHugger site that low pressure sodium lamps are the most efficent. I alway think that driving under their orange light is nice, apparently the police have a problem with them, but then you don't see a lot of police out at night in the UK (They hide in the police station, away from all those nasty criminals).

The only problem with using LED lights could be visibility. If you try using a LED torch to find something in the loft, it is harder to see, than with a normal torch, although the LED appears to be brighter.

The city website and your post say that the city is saving and will save tons of money on energy cost with the LEDs, but then the Treehugger/Wikipedia write up shows that the normal orange street lights are more efficient. Are they saving money because the LED lights just don't light up as much area? If so then in the end they will have to put up more street lights as people get grumpy from the increased dark areas, thus losing out on savings. Will someone please explain this to me?

James: If I'm reading the article correctly, the replacement costs are so much lower there's a long-term savings. And it's not just the cost of the lamps, it's the labor. Labor can be pretty expensive.

"The city hopes to be able to cut its $1.39 million street lighting budget in half by switching to LED street lighting, and that accounts for just the energy savings."

That is what threw me.

First, LEDs aren't always less efficient than low-pressure sodium lamps. Several LEDs have been designed that are more efficient that Low-pressure sodium, they just aren't available yet.

Second, American cities rarely use low pressure sodium nowadays. I have no idea why, apparently they want a broader spectrum of light and are willing to pay for it. The LED lamps must be significantly more efficient than whatever it is that Ann Arbor is currently using. It could very well be halogen, which is fairly common nowadays, and also fairly inefficient.

Thanks for the report. That is very cool and definitely sustainable.

Currently the LED efficiency could reach more than 80lm/W. It really close to the sodium light can provide. We also need to think about the controlable feature that could suddenly adjust the light output to getting more energy saving. Lable cost, digital controllable, and higher efficiency will lower the total cost a lot in today's LED market.

I'm an Ann Arbor resident who just discovered this discussion, and perhaps can clear up a bit of the confusion about the potential savings here with the LED lighting. If in fact Ann Arbor had already been using LPS street lighting, then the switch to LED technology would in fact be a decrease in efficiency and an increase in energy costs. The truth however is that most street and sidewalk lighting in Ann Arbor is currently less efficient MH, and of designs that throw 10 to 50 percent of their light skyward rather than toward the ground. So with the new LED designs we will both increase efficiency over the replaced lamps, AND stop wasting energy by sending light off into the sky.

Please take a look at this site, LED street lighting has now just moved forward.
No More diodes, we are now looking at chips! Very interesting.

one problem with led that appears to get lost in the
more lumens/watt race is the relative scarcity of some of the materials needed to produce these LED. similare
problem that solar power efficiency is hampered by.
good material availabillity - ~low efficientcy
low material availabillity - good efficiency (>30%)

To get the best in energy savings, and by far the longest lasting and highest quality LED lighting, visit our website, www.modalight.com

I have been told from a reliable source that LED bulbs don't use heavy metals, therefore thay can be recycled without problems from heavy metals creating more pollution. A matrix can be really helpful in determining the most green product available. LED rates very well in a green matrix.

We are the LED application design and manufacturing company in Taiwan.

We have developed new LED street light using Nichia LED for the market.

Low pressure sodium lights are rarely seen in the USA but are frequently seen in Europe and give off a distintive yellow glow. High pressure sodium lights are often seen in the USA and give off a peach colored glow. Most "non-architectural" street lamps (e.g. those suspended on metal arms from wooden poles) that give off a white light are mercury vapor lamps. Most architectural street, sign, and building lamps (e.g. the Ann Arbor street lamps) that give a white light are metal halide lamps.

Mercury vapor lamps are normally inexpensive to install and relamp and their white light is not offensive but they are not as energy efficient as high pressure sodium. High pressure sodium lamps are usually inexpensive to install and relamp and are energy efficient but their peach light color is unappealing. Metal halide fixtures are usually energy efficient and provide very accurate color rendering, but they are usually more expensive to install and relamp (and in many cases, utilities and municipalities are reluctant to replace and throw away functioning fixtures, unless they have a good reason to do so as did Ann Arbor in its downtown pedestrian shopping district). Hence the compromises with all three types of lamps.

just thought i should put up the actual makers of the lights in a2. im new to the company but i am very excited about the green possibilities for out future here at relume. check it out!

There's a bit of confusion in the postings regarding the Ann Arbor, MI, LED retrofit lamps provided by Relume.

Advanced, white power LEDs [Cree XRE] can deliver over 107 lumens per Watt and are nearly equal in luminous efficacy to HPS lamps but with a BIG difference: They depreciate in luminous output at a MUCH lower rate.

Using advanced thermal management, the Relume LED light engines will deliver 70,000 hrs of light [to 70% of initial output] while HPS lamps would degrade in 20,000 hrs to something on the order of 40% of initial output.

HPS lamps may deliver more gross lumens per Watt, but current published research shows that the yellow / pink quality of the light has a low CRI [25] and is marginal in terms of visual acuity. In fact, 5500 K LEDs that deliver 1/4 the gross lumens of an HPS lamp are found to deliver BETTER acuity.

LPS lamps are another matter - with a CRI of 0, they aren't really suitable for general lighting and as efficient as they might be, humans can't see too well in the 590 nm, monochromatic light ... so why use them?

Regarding 'equivalent'luminous output, the newest LEDs [CRI = 82] deliver the same illuminace on the roadway as standard MH lamps at half the input power, primarily because the LED flux can be directed onto the street rather than the sky. The LED globes in Ann Arbor were originally MH lamps that used 2X the power of the LED light engines we installed. These LEDs are projected to last 10-12 years instead of 2 -3 for the MH bulbs.

While the AA globes aren't full cut - off because of their geometry, many of our LED luminaires are dark skies compliant.

Hi Post

Ironically this is all dated now. There is a dutch company who have patented a new power management system specifically for intelligent streetlights. They are LED units www.lioris.eu and they have a new system using Zigbee. This allows for 99 slaves for every master. The end result is focussed lighting at the same brilliance as sodium lighting with heads the same price a sodium heads but they speak to each other using GPRS and Zigbee.

End result - Streetlights that eliminate light pollution and reduce energy consumption by about 90%. This power managenemt system apparently is going to be licensed out to other streetlight vendors.

Street light energy management systems [ELMS] have been around for years - that's what is dated.

Major players include Virticus, Echelon and others. Mesh networks using a wide variety of license free communication protocols such as Zigbee or any number of systems operating in the ISM bands have also been around for a while. NONE of this impacts the importance of luminous efficacy, useful life and life cycle cost. Any number of manufacturers boast about having the 'magic answer' to green, cost efficient LED street lighting, but the proof is on the street - so to speak.

Relume has more installed LED luminaires than all other companies combined. We even publish our erformance ... photometric IES files developed by independent, acredited testing laboratories. No other company does this ... if THEY have the ultimate answers, why not publish third party test results?

The fact is ... nobody has the answers to all LED lighting problems. The cost of the fixtures is still high and we have problems [$$$] duplicating the performance of 400 W H.P.S. lamps ... even when we employ the most aggresive thermal management methods.

Unfortunately, the field is over-run with pretenders who think that LED solutions are the result of press releases!

You know... after looking at all the coments I have discovered that most of you are so mis informed that reality has not set in. The led market is very strong; however, it is so expensive that it will never be able to replace mercury vapor or incandescent lights. A perfect example is the led street lamp. The lamp costs alone is 800 dollars EACH!!!! To make this pay for the so called savings would take 20 years and then will need replacement. The claims of 100,000 hours for those high powered leds life span goes down drastically with power.You would be lucky to get 20 k hours at best. True, you will save at least half in electric, but you will never be able to recover the investment for replacing the lamps. I have connections in China for the company that makes those led,s. MY cost alone for just a 175 watt eqal powered led is 650 dollars. So until they are mass produced it will never work. Mark

HPS is used heavily in the agriculture industry, so there are many test comparing the two.

LED, even in it's somewhat immature stage is 20-35% more efficient.

Plus they last so long they are vastly more cost effective. HPS not ONLY burn out fast, but their lumens output fades quickly over time. SO, even if your HPS lamp lasts 2 years it will likely have only 70% the output it use to.

Another smart move is getting the light CLOSER to the ground so you don't have to use such high wattage such as parking lot lights which tend to be very high up for no apparent reason.

Distance greatly diminishes light output. Smarter made reflectors and light enclosures that don't become cloudy or translucent over time would help a lot also.

How much of that wattage is being absorbed by the inferior reflector and the foggy glass over it.

LED's are vastly more weather resistant also and they don't produce that nasty electric interference that HPS use. They also don't get burning hot to the touch AND they can't shock you dead easily like an HPS ballast could.

It's horrible congress is too dumb to push this technology. LED's unlike HPS have the potential to get A LOT cheaper. HPS is a widely used technology and is very cheap via mass production.

LED is simpler and will cost much less as the industry matures. However, smart investments from the states would speed that up. Ideally congress could give them some direction on reliable savings.

I think LED is one that we can bet on to be the future of lighting. We are probably not going to do much better than LED anytime soon and we can probably improve it considerably.

We've used LED's in electrics for years, but only recently has the blue LED come out allowing for white LED's to be produced. I feel unlike HPS, LED's are conservatively rated AND like fluorescent their lumen output does not fade quickly over time as HPS does.

HPS is a good technology, but it has no real place now that white LED's are out. There are other high efficiency light techniques that are cheap such as sulfur lighting, but nothing so commercially viable as LED.

You can even buy LED replacements to your flashlights now.

We are pushing CFL on the states now. We probably should skip right to LED since energy prices are ONLY going up and it takes gas to send the guys out to change the light bulbs. The biggest cost is likely the energy, then the maintenance, then the equipment. SO, the increased purchase price of LED is the least important of the costs and will come down significantly as more people buy into the tech.

Can I have a list of the manufactures of these products

As to Mark's comments on the cost of LEDs ... our company, Relume Technologies of Oxford, MI supplied the 1000 LED street lights for Ann Arbor, MI. We sell these for something on the order $ 400. Relume uses Cree LEDs that currently sell for about $2 each in million lot. Each street lamp uses 48 LEDs and a power supply ... do the math. The lamps we provided are equivalent to 100 Watt M.H. lumnaires in light output and consume less than half the power. Independent [third party] lab testing verifies that these Cree LEDs will deliver over 70,000 hrs. of service [to 30% degradation] when the LEDs are operated at or below the design junction temperature of 75 degrees C.

We have sold other led fixtures to Battle Creek, Grand Rapids & Oxford, MI, Canton, OH, Weland, ON [Canada] and are under test in over 100 other locations.

Why would anyone buy these things if they can't get a payback?

Could LED streetlights be individually powered with solar energy?

Unfortunately, solar street lighting isn't practical. That said, if one were to intermittently turn on the street lights a few hours a night, [on an occupancy basis] solar charging might work.

Total average solar flux is on the order of 1 KW per square meter. Affordable solar panels convert only 12 -15% of that energy into electric power that can charge batteries. If we assume a 1 square meter solar panel [~$ 1000] is attached to each street lamp pole and can collect sunlight for 6 hrs. per day, we could store about 600 Watt-hrs of energy - after charger / battery losses etc. In some parts of the U.S. [New Mexico] we might be able to power a 60 Watt street light [not much light] for around 10 hrs. with the stored power.

The problem is that for most of the U.S. we have at LEAST one cloudy day for every sunlit day - making the proposition impractical.

I work for a uk company www.gemmalighting.com who design and manufacture LED street lighting in the U.K

Gemma Lighting and Displays has proven to save companies across the U.K upto 75% off their energy bills and save £££ in maintanance.

LED technology is now at a competitive price and can provide a quick ROI.

Look at all these companies boasting their wears here! It's absolutely incredulous and offers no relevance to the story here.

I on the other hand have something that is truly the most efficient right now. Our patented product uses existing lights and makes them 18% to 33% more efficient (depending on the product you choose and the setting) while extending bulb life by 20% to 40% percent and ballast life by 80% to 200%.

We use a passive magnetic technology to condition the power and reduce the voltage after the initial strike. This process maintains the same amount of lumens while eliminating the waste (expressed as heat).

Our products has been used for the last 20 years with absolutely no defects or maintenance required.

The best part about our product is it works with existing facilities (no expensive retrofits!).

I would be happy to provide anyone with more information and show field studies from the City of Anaheim (the home of Disneyland) and the City of Sacremento (the home of "The Governator").

One thing that you are all forgetting about these lights is that there is a large value in the LED lights in that they can be focussed on a specific area. One post did say that the light would be thrown where it belongs (on the street) instead of in the sky. This makes for easier compliance with the Dark Skies Initiative, which aims to reduce light pollution and its associated wildlife impacts. Wilflife inpacts are huge when it comes to this initiative by the US Department of the Interior. This is a consideration. There is a study online (PDF Format) that lists the Ann Arbor information from which you'll find that most of these posts are opinion, not fact. LED lights (in almost 100% of the cases) save money. Even if the pay off is 15 years (which is a maximum), the energy and replacement costs of LED Street Lights, combined with the environment impact (positive), makes this a worthy capital investment.

Can I have a list of led street lamp manufacturers

Dear Madam/Sirs,

Our LED Street Light and related fixtuare are very much unique and reliable.
As you know all the clients very well, the LED is weak on the heat generating by itself. Unfortunately, till today, there are not any solution and technology to reduce the heat generating by itself.
so, we should consider how to radiate the heat. If we effectively radiate heat of LED light, we can drastically increase the life time of LED light and and keep their illumination during the original life time of LED.

So, we have developed LED street light(63W and 108W) which have been radiated heat drastically and launched the complete set of LED street light in Korea(one of well known city located in southern part of Korea).
Any body who are interested in our LED Street Light with Fixture, please get in touch with us at any time. We will never let you down in the points of your concerns.

If you need more details, please feel free to contact us at any time using our e-mail and cell phone.

Low LED power consumption yields energy savings of 20% to 50% over high pressure sodium and mercury vapor street luminaires at today’s levels, as indicated earlier. This energy efficiency is expected to increase with ongoing advances in solid state technology.
LEDs’ ability to minimize wasted light lowers power demands even further by reducing the lumen requirements for a given street fixture. Since light distribution can be controlled on an LED-by-LED basis, engineers can effectively light the target zone without the light pollution created by a single-beam solution.
Mercury-free LED construction makes solid state street lamps safe for landfills while also complying with mercury bans such as the European Union’s RoHS directive.
Long LED life lengthens replacement cycles and associated fuel usage by maintenance crews, while also extending fixture life and thereby reducing the burden on the waste stream.
LED street lights reduce pollution and carbon footprint via energy savings that lowers carbon dioxide and mercury emissions from coal-burning plants, as well as reduced fuel consumption by maintenance crews dispatched for bulb replacement.
We are a manufactory specilizes in researching and producing LED lights,if you have any questions regarding LED Lights,pls contract us,we can try our best to support you!
