The Using Of LED Flood Lights
This short post is going to explore LED Flood Lights.
If you are trying to find one of the most popular type of flood lights in the industry today then you should be impressed at the up-to-date lighting development which has been obtaining remarkable feedbacks from consumers; it is generally known as LED lights. LED which is short for light emitting diode has been widely used in many devices mainly as indicating lighting.
LED flood lights have completely revolutionised outdoor lighting and have made LED the perfect lighting solution for any sort of outdoor weather condition. LED flood lights are more economical than a normal floodlight for the reason that it can save you energy up to 80% compared to a standard incandescent light. The life span of an LED lamp is evaluated to be 100,000 hours long and LEDs used in lighting can last up to 30,000 to 50,000 hours; you'd be burning out 2 or 3 or even more fluorescent lights just before an LED flood light will begin to flicker.Since an LED flood light will likely be utilized in the outdoors, it's fully maintenance free of charge. It is always prepared to make use of given that it powers on with just a press of a switch in comparison to some outdoor lighting that flickers before powering on. With an LED flood light, you will hardly ever need to sacrifice with lighting conditions, it may be as bright as a regular incandescent or halogen bulb but with less energy consumed.
An LED flood light is an excellent investment seeing that it will make available to you years of usage unlike normal lighting that will flicker and fail following a year. Even on a foggy day, you would be able to be sure that an LED flood light will light up your garden without fail, it may also do the job in snow or sleet weather conditions.
When browsing on the internet, you may be able to obtain the best value in LED flood lights. You will probably find web sites that are committed to introducing this modern lighting technologies to regular purchasers. You could be able to view an extensive gallery of LED lights and also flood lights and also read extensive info on how LEDs can do magic for your dwelling and enterprise.
The most typical LED flood light could be the 100W assortment which is available in white, red, blue and green colors and RGB. You may be able to even get much more savings if you purchase by bulk for your dwelling or your business. With LED lights, you can efficiently illuminate any area for just a tiny proportion of the energy charges of a standard light bulb.
Other floodlight types are the 20W, 40W, 30W 50W ,60W and etc option. You could be able to pick the ideal flood light depending on the size of your garden or the location that wants to be lit.
LED lights has been creating superb reviews with regards to energy efficiency. Absolutely conventional lighting are not able to comparable to the power and lighting flexibility of an LED light. A growing number of house owners are using LEDs as their indoor and outdoor lighting source and it is likely that more and more people will do the exact same in the near future.
The author is interested in energy-saving, energy efficiency sector, particularly in LED lights technologies and led lights products such as led strips, led bulbs and led tubes, led flood lights etc. The final copyright of this article belongs to Sielement LED Lights, but welcome anyone to republish.

Strong results for Veeco, more MOCVD sales for Aixtron
Veeco continues to see strong orders from China and other regions, while Aixtron has reported more reactor sales in Taiwan.Veeco has reported revenue of $255 million for the quarter ended March 31, 2011, of which Led & Solar revenue was $215 million and Data Storage revenue was $40 million. Revenue was down 15% sequentially, but increased 89% from the same quarter last year. The company's gross margin was 51% and non-GAAP net income was $57 million.
Veeco's bookings for the quarter totaled $231 million, of which $198 million was in LED & Solar. John Peeler, Veeco's CEO, said: "We continued to experience strong demand for MOCVD systems and, while China remained the majority of our bookings, we also received orders from key customers in Taiwan, Korea and the US."
In February 2011, Veeco announced its newest-generation MOCVD system, the TurboDisc MaxBright. Peeler said that Veeco shipped three MaxBright four-chamber systems during the first quarter of 2011.
"Orders have been received from three of the top-tier Taiwanese LED makers, as well as from key customers in Korea and China," said Peeler. "Customers are clearly recognizing that we are helping to enable the industry's transition to Led lighting with a unique value position and the most productive MOCVD systems on the market."
Looking forward, Peeler said that Veeco expects MOCVD order patterns to "remain lumpy from quarter to quarter depending upon the timing of customer deposits. We see order strength continuing in China as it builds its LED infrastructure for solid-state Lighting, and quoting activity in Korea and Taiwan is also picking up with improved utilization rates being reported at key customers."
Further Aixtron systems
In related news, Aixtron SE announced that its latest Close Coupled Showerhead MOCVD platform system, the CRIUS II, has been successfully qualified for mass production by Chi Mei Group.
The 55x2-inch wafer configuration CCS CRIUS II was installed and commissioned by the local Aixtron service team at facilities near the Southern Taiwan Science Park.
Also, Aixtron has received repeat orders from Taiwan-based led chip maker Epistar for multiple AIX G5 HT reactors in a 14x4-inch configuration. The systems are delivered in the first and second quarter of 2011.
Aixtron described the repeat order as "a further endorsement of G5's very rapid time-to-production and excellent system-to-system reproducibility, both of which are key factors in a highly competitive market and a considerable driver of cost reduction."
Ming-Jiunn Jou, president of Epistar, said: "The new reactors will form the backbone of our planned capacity expansion for our high-brightness LED production program. In particular, we have been impressed by the run-to-run and system-to-system reproducibility the G5 has shown. This makes the G5 the leading MOCVD system in terms of throughput and yield, allowing us to quickly ramp up our capacities and expand our product portfolio even further in the direction of solid-state lighting products."

Rensselaer Polytechnic Institute Makes a Breakthrough on Green LED
Rensselaer Polytechnic Institute Makes a Breakthrough on Green LED
It's reported that Researchers from Rensselaer Polytechnic Institute have created a new method for manufacturing green-colored Leds with greatly enhanced light output.Led by led by Christian Wetzel, professor of physics and the Wellfleet Constellation Professor of Future Chips at Rensselaer, the research team etched a nanoscale pattern at the interface between the LED's sapphire base and the layer of GaN that gives the LED its green color.
It has received a good result. The new technique results in green LEDs with significant enhancements in light extraction, internal efficiency, and light output.
According to Wetzel, currently, every computer monitor and television produces its picture by using red, blue, and green. And we already have powerful, inexpensive red and blue LEDs. A similar green LED should lead to a new generation of high-performance, energy-efficient display and illumination devices. This new research finding is an important step in the right direction."

Rensselaer researchers boost green LED efficiency
Rensselaer researchers boost green LED efficiency
Research at Rensselaer Polytechnic Institute leverages a nanoscale pattern to boost the optical efficiency of green Leds in the lab.Green LED efficiency has long lagged behind the capabilities of red and blue devices, but researchers at the Rensselaer Polytechnic Institute (RPI) have reported significant improvements in the lab. The team is forming nanoscale patterns on a sapphire substrate that boosts light extraction, internal efficiency, and light output.
More efficient green LEDs would benefit both solid-state Lighting (SSL) in general-illumination applications and TV and display technology. Equally efficient red, green, and blue (RGB) LEDs could yield white light for illumination and could improve the color gamut in display or TV applications.
Rensselaer researchers boost green LED efficiency
Some early led backlights for TVs utilized RGB LEDs, but the designs generally had to include two green LEDs for every red and blue one - adding significant expense and power consumption to the design. Likewise, RGB LEDs have been used in lighting but the need for extra green LEDs limits the applicability.
Green LED inefficiency stems from a semiconductor physics phenomenon called the charge separation effect. In green LEDs, electrons and electron holes are separated in the quantum-well region of the device. Light is generated when electrons combine with electron holes, but the separation results in fewer such combinations in green LEDs. Researchers have struggled for years with the problem.
Christian Wetzel, Professor of Physics and the Wellfleet Constellation Professor of Future Chips at RPI, is leading the green LED research team. The team etched a nanoscale pattern between the sapphire substrate and the gallium nitride (GaN) material in which the LED is grown.
The team reports a doubling in the internal quantum efficiency of the LED. Moreover, the design enhances light extraction by a factor of 58%. The result could be brighter green LEDs although its unclear how soon the research could be applied in LED production.
"Every computer monitor and television produces its picture by using red, blue, and green. We already have powerful, inexpensive red and blue LEDs. Once we develop a similar green LED, it should lead to a new generation of high-performance, energy-efficient display and illumination devices. This new research finding is an important step in the right direction," said Wetzel. "Green LEDs are proving much more challenging to create than academia and the industry ever imagined."
The research team published the results of its work in a paper entitled "Defect-reduced green GaInN/GaN light-emitting diode on nanopatterned sapphire" that was published in the Virtual Journal of Nanoscale Science & Technology.
Wetzel's team was supported by the US Department of Energy, National Energy Technology Laboratory (NETL) Solid-State Lighting Contract of Directed Research, and the National Science Foundation (NSF) Smart Lighting Engineering Research Center (ERC), which is led by Rensselaer.

Positive Aspects Of Applying LED Tubes Over Other Fluorescent Tubes
This content talks about the positive aspects of employing LED tubes which are energy efficient and environmental protecting.
In these days, in this community of increasing environmental interest, demand for energy-saving bulbs is growing continuously. A lot of people and properties are in the market for lighting options, which could be inexpensive, quite practical and will reduce power utilization. LED tube does seem to be a better solution for the public.
LED is the composition of light-emitting diodes. Actually, these diodes are miniature semiconductors chips, that change electricity into light. The old incandescent lamp provides light as secondary output from intensely heated filament, which necessitates a lot of energy. LEDs conversely convert most energy flowing through them to light that’s why it could be significantly more efficient than the traditional incandescent lights.
The newest technology advances in fluorescent lighting is considered to be compact fluorescent lamps (CFLs). LED Light is however more efficient since it has much longer lifespan (25 times) than that of incandescent bulbs and (8 times) than that of fluorescents.
LED light is presented in different colors which generate a variety of effects in an area. When LED light is going to be chosen, either for workplaces or for residential installation, the level of lighting in that place should be evaluated. This is as a result of a number of levels, which could generate a bright glow or soft feel repeatedly. The reason is that LED light source is originally directional light source. The light output by LEDs is very directional. In another word, its beam angle is usually fairly narrow. Such characteristics could be negative aspect in certain lighting systems, for example, the applications which call for smooth and even lighting distribution. Yet, this downside is not insuperable. Lighting developers usually implement a mist lamp cover rather than a clear cover for the LED tubes, therefore the light output could be very soft and evenly distributed. The price for this solution is some loss on light output – typically, roughly 10% of light output loss. Another use of a diffused lamp cover is to widen the beam angle of the tube, but still, LED tubes could not have a 360-degree beam angle just like the conventional fluorescent tubes do under present technology stage.
LED tubes are generally made of a silicon substrate that houses many LEDs. The substrate is enclosed in a PC pipe (cover) which makes it ready for installation. The LED tubes, unlike the fluorescent tubes, compact fluorescent lamps or energy-saving bulbs, do not contain any toxins or chemicals therefore could be released as common throw away.
One can find main health and environmental hazards, that can be linked with the incandescent and fluorescent lights because of the existence of mercury, that is highly risky and toxic. People who have worked under the enviroement (e . g ., warehouses and offices) where fluorescents are installed, may have a good comprehend of that the flickering lights can cause vision and eye problems, furthermore, some may even cause headaches and dizziness. While LED tubes do not engage such troubles.
Figure out the rewards of applying LED tube lighting for your office or home! You may find it an simple and easy way to enjoy a more comfortable life and at the same time to conserve your power bills.

Benefits of LED Lights Replacement
This article talks about the benefits of LED lights compared with traditional lights such as incandecent and fluorescent lights. The advantages of LED lighting is not only it can save the electricity bills, but also it can save replacement and mantenence cost since it has much longer lifespan.
The foreseeable of home lighting will very soon be the vast distributed adopting and utilize of green energy-saving LED lights. Though the current market for LED lights products is mainly geared towards supporters and the pros, the upsides of LED lighting will raise demand for more cost-effective LED lights. SSL (Solid-State-Lighting) is an interesting field and its been forecasted, that soon, energy-saving LED lighting products are going to be reliable and affordable sufficiently to replace incandescent and fluorecent lights for common use in our homes, in public places, in car parking lots, in street lights, in outdoor signs, in super markets, in shopping malls and offices.
The working lifespan of current LED lamps is 100,000 hours theoretically. This will be more than 10 years of continuing running, or in another caculation, say 33.3% operation (that is 8 hours per day), 34 years of lifespan. The long operational life of an LED light is great advantage compared to an incandescent bulb or a fluorescent tube, which is approximately 4000-6000 hours.
When it comes to cost, it seems a little unfair to LED lights. Most people like to carry out some 1 on 1 comparison between the cost of LED lights and traditional lights such as incandescents, fluorescents and halogen lamps. With incandescent lamps, the true and hidden cost is the electricity bills and the maintenance fee (including the replacement bulbs and the labour fee). When comes to the commercial sector, for example, for shopping malls, car parks, office buildings and highrises, maintenance costs for replacing the light bulbs or light tubes, can be significant. While LED lights here could be a perfect solution.
As soon as developed efficiently, an LED circuit will probably come to 70-80% efficiency, that indicates 70-80% of the energy has been converted to light rather than other forms of energy such as heat. While for incandescent bulbs, only 10- 20% of electricity is used to generate light, at the same time, 80-90% of electric power has been wasted to generate heat. Take a simple example, say if I light up my room with a 100 Watt incandescent bulb (8 hours per day), and the electrical fee is 10cents/kilowatt hour, then for 1 year, my electrical cost for this bulb would be $29 expense, but $23-$26 of this $29 will be spent to heat the room, only $3-$6 is actually devoted to light the room. And if an efficient LED light is used, the energy fee would be only about $9-$11 yearly – 60%-70% saving on electricity each year. Please have in mind that the savings on maintenance and replacements during the next years has not been counted yet.
Although LED lighting hold superb advantages compared to traditional lighting.The critical constraint to the wide adoption of LED lighting is still the present relative high cost of LED lamps as the initial investment. Despite the fact the price is constantly going down, LED lamps are still expensive. Usually, a 3W LED globe bulb, replacement of a 25 watt incandescent, costs around $40. Despite the fact that LEDs are expensive, the initial cost will be paid back in long term, by saving utility and mantenance costs. The best value comes from commercial applications where maintenance and replacement costs are costly.
It is predicted that as the new improvements of LED technologies comming, there will be progressively more LED light adoptions in residential lighting applications. In fact, LED technology has been explored and developed for several decades but only a few years ago, as the white light LEDs were developed, LED lighting began pratical for illumination. And in these short few years, a fast rising industry has being formed. This could also be a proof that LED lighting holds a very promising future. And this future won’t be long.

What Is LED Light
Speaking of LEDs, probably one would have heard and found that everywhere, the computers, the cell phones, the traffic lights, the flat screens and so on. LED’s everywhere in our daily life, providing indications . However, with some exceptions, the initial intention of LEDs was for indication but not illumination, at the very beginning, LED’s had nothing to do with general lighting.
New developments, however, are starting to bring SSL (solid-state lighting) into our homes in the near future. In fact, nowadays, you will find there are many on-line shops that are already selling some LED lights products such as MR16 and GU10 spotlights and LED bulbs.
An LED, originally referred to Light Emitting Diode, is one type of circuit element emitting light when electricity moves through it in the specific direction. Just like a normal diode, electrical current will be blocked when it tried to pass through the opposite direction of the diode. With a positive voltage to the positive siide of an LED, the electrons that must jump down in energy when they cross the diode, in this process, the electron will be emitting the lost energy as light – that is the principle how LEDs emit light. This light is at one specific frequency, and the frequency will depending characteristics of the materials being used. When generating white light that may be applied to illumination , it will need a mixing up of many different clolours – something LEDs did not seemed to be able to accomplish in the past.
Red light was the very first visible light LED to be created, in 1962, followed by yellow and green. Later (actually about 30 years later), in early 1990′s, blue-spectrum LED’s were invented – an enormous advance in usefulness, due to the fact blue light could be joined with red and green to produce white light. Nevertheless, this method was not efficient, and corporations were battling to develop a single diode that is able to generate white light by itself. Then, in 1993, a corporation referred to as Nichia developed the first white LED utilizing a blue LED with a phosphor coating. The coating was the secret to success – it provided sufficient shifting of the light wavelength coming from the diode itself to generate white colored light.
So why, aren’t we using LED lights (in most of our homes) – significantly more efficient than either incandescent or fluorescent lights – to our homes, offices and warehouses? The primary challenge, clearly, is cost. Current white LED’s substrate made up of sapphire additional mirroring layer to reflect light which will otherwise be lost. As a consequence, LED lights that are available on the market cost somewhere around 10, 20 or even more times than traditional lights, too much for the average consumer.
Researchers have realized one way of significantly keeping down the expense of white LEDs by reducing the expensive layer of sapphire. As an alternative solution, they used silicon as the substrate and zirconium nitride as the reflector. This had never been carried out before, primarily because silicon reacts with zirconium nitride and changes its properties. The study solved this by locating a layer of aluminum nitride between the silicon and zirconium nitride.
LED lighting carries various benefits over traditional lighting, most especially in efficiency. LED’s are at the same time more durable than incandescent or compact fluorescent lights, and have the advantage of being without having mercury – a chemical discovered in compact fluorescent lights that makes them difficult to get rid of.
The industry is booming, it is expected that LED lights will be adopted widely in homes and office in the near future (some expect it will be 5-10 years). There are still technologies issues, but the LED industry may finally find its way.

Rutland Village Benefits from LEDs
Recently, Rutland village has benefited a lot from LEDs.
Market Overton Parish Council in Rutland reported the savings after LED bulbs were installed, replacing the usual sodium system.
According to Deputy chairman, Andrew Stewart , the parish council's average monthly energy bill had gone down from about £80 to about £15 since the changes. Maintenance costs are also expected to be around 90% cheaper than in previous years.
What's more, 80% of their street lamps have been fitted with time switches to turn the lights off between the hours of midnight and 0530 GMT.
The new system is now attracting interest from neighbouring villages.

CFL vs. incandescent: Battle of the bulb
Compact fluorescent light bulbs are often mentioned as one of the easiest ways to shrink your power bill and your carbon footprint. They present the quintessential green-green situation: saving money and helping the environment. What's not to like?
There's the higher retail price - who wants to pay three bucks for a light bulb when it's sitting right next to ones that cost less than a dollar? But the CFL can last up to 10 times longer than incandescent bulbs, meaning you'd have to buy 10 of them during a single $3 CFL's lifespan. Each CFL saves about $30 during its tenure, according to the U.S. Energy Star program, and pays for itself in about six months.
One of the most potent threats to CFLs' superiority isn't their cost, but their contents. There's a small amount of toxic mercury in every one, which can be absorbed or inhaLed, potentially causing brain damage in adults, children and especially in fetuses. Fumble a CFL while changing a light, critics warn, and you unleash a poisonous fiend in your home. Throw it out and you're dumping mercury in landfills.
Those are both valid concerns, if sometimes a bit overblown. You should be careful when cleaning up a broken CFL, but don't go nuts - Snopes has debunked the myth that breaking one requires calling in an environmental cleanup crew. Keep kids and pets away, open the windows and resist the urge to vacuum, since that can kick up mercury vapor into the air; see the EPA's advice on cleaning up broken fluorescent lights for a complete guide. When they do eventually burn out, make sure to dispose of them properly.
Why do CFLs contain mercury?
Fluorescent and incandescent lights generally work the same way: They zap certain types of atoms with energy until their electrons freak out and release photons of light. Incandescent bulbs do this by shooting electricity into a thin metal filament surrounded by inert gas and encased in a glass shell. Metal normally emits invisible infrared light when heated like this, but get the atoms worked up enough and they'll produce a visible glow, too.
Metallic atoms are also the light source in fluorescent lamps, but they use vaporized mercury instead of a solid filament. The incoming electrical current is carried through a glass tube, straight or coiled, that's filled with mercury vapor and argon gas. The electrified mercury atoms begin vibrating and releasing invisible ultraviolet light, which in turn excites a fluorescent phosphor coating on the inside of the tube, finally producing the visible light.
(It's this jittery relationship, combined with a jumpy magnetic ballast providing electricity, that gives fluorescent lights their infamous flicker. Electronic ballasts don't have this problem.)
Mercury is a crucial part of how all fluorescent bulbs work, and replacing it is a daunting task. Still, manufacturers have cut back on how much they use - CFLs' mercury content dropped by at least 20 percent from 2007 to 2008. While the bulbs contained an average of 4 milligrams a few years ago, many now use as little as 0.4 mg. By comparison, mercury thermometers contain about 500 mg of mercury, and older nondigital thermostats contain about 3,000 mg.
Does mercury overshadow CFLs' benefits?
Fluorescent lights only release mercury when their glass breaks. Consider how often you shatter a light bulb while changing it, and divide that number by 10 - since a single CFL requires about that many fewer replacements - and that's your risk of mercury exposure.
An incandescent bulb doesn't contain mercury, but it still has a higher overall mercury footprint than a CFL, thanks to the coiled tube's renowned energy efficiency. Coal-fired power plants are humans' No. 1 source of mercury pollution, and energy-intensive incandescent bulbs require those plants to burn more coal than CFLs do. That extra coal burning releases far more mercury than even the combined amount inside a CFL and in the coal emissions needed to light it.
While most fluorescent lamps finish their lives without shattering, however, it's another story once they're thrown out. They can easy break in trash cans, Dumpsters or en route to a landfill. It's only a small amount of mercury, but it adds up as more and more people are buying them, and it also endangers sanitation workers who don't know they're carrying bags containing mercury vapor. All the more reason to read up on the EPA's guidelines for properly disposing of fluorescent lights.
Are incandescent bulbs burned out?
The main downside with traditional light bulbs is that they use only 10 percent of their energy to produce light, burning off the rest as heat. They've wasted 90 percent of the electricity people have been feeding them for the past 130 years - electricity that was mainly generated from coal and other fossil fuels. Congress put its foot down with the 2007 energy bill, introducing tougher efficiency rules that are expected to crush the market for incandescent bulbs beginning in 2012. Within a few years, the ever-cheaper CFL may dominate the Lighting market.
But don't count out Thomas Edison's original bright idea just yet. Despite the U.S. Department of Energy and EPA pushing CFLs, many people are still turned off by the light they emit, which is slightly bluer and more flickery than incandescents' warm, steady glow. To meet this lingering demand as well as the upcoming federal efficiency standards, several companies are scrambling to roll out a wave of next-generation incandescents. These bulbs keep their familiar shine and radiate less heat by reflecting some of the filament's light back inward. They're still more expensive than CFLs, but the price of such technology usually drops if it's successful.
Light(s) at the end of the tunnel
The future of artificial lighting is hazy, thanks to several recent technological and regulatory upheavals. Traditional light bulbs are almost certainly doomed once the new U.S. efficiency regulations take effect in 2012, leaving CFLs and improved incandescents to fill the void.
There's also a dark horse light bulb lurking in the shadows - light-emitting diodes, better-known as LEDs. These are already common in a variety of devices, ranging from the blinking red light on a video camera to the green power button on a computer. LEDs are more efficient, versatile and long-lasting than either incandescent or fluorescent lights, emitting light in a specific direction rather than radiating it outward indiscriminately, which wastes energy. They also absorb back what little heat they produce into an internal heat sink, leaving the LED itself cool to the touch.
While LEDs may seem like the obvious choice, they're still not entirely practical as a commercial substitute for incandescents or fluorescents. Several companies make bulbs that rely on diodes, but they aren't cheap. Odds are good the technology will eventually let LEDs overthrow their predecessors, but until then, the EPA and DOE are giving CFLs the green light.

LED Lights Replacement Case Study: City of Centennial, Colorado Saves More than $50,000 a Year
As part of a city-wide sustainability initiative, officials in Centennial, Colorado recently completed a project to upgrade each of the city's traffic and pedestrian countdown signals from traditional incandescent units to Dialight's high-efficiency, low-maintenance ITE-compliant Led traffic signals. The project, funded by the U.S. Department of Energy's Energy Efficiency and Conservation Block Grant Program (EECBG), not only improved visibility for drivers and pedestrians, but is expected to save the city $50,000-$60,000 a year in energy and maintenance costs.
Modern City, Progressive Planning
Appropriately named in honor of its citizens' September 2000 vote to incorporate, the City of Centennial is not only one of the youngest cities in the State of Colorado, but also the safest. With a vibrant community that blends the convenience of city living with the beauty of semi-rural neighborhoods, Centennial has been named Colorado's safest city for six years in a row. Home to nearly 110,000 residents, the city's backdrop against the picture-perfect Rocky Mountain skyline makes it one of the most beautiful in the Great American West.
In a progressive move intended to improve driver and pedestrian safety and reduce energy consumption and expenses, the city has recently completed a full replacement of its out-dated incandescent traffic signal balls, arrows and pedestrian indications with Dialight's ultra-energy efficient ITE-compliant traffic and pedestrian signals.
"Safety, reliability and overall brightness were significant concerns," said Craig Faessler, P.E., City Traffic / Transportation Engineer with the City of Centennial. "But, so were the energy consumption and maintenance costs. An upgrade to all-LED addressed all of these issues."
In addition to the fact that some of the faded lenses were at least 20 years old - as old as the signals themselves- the units consumed an exorbitant amount of energy and demanded nearly continuous maintenance with regular bulb changes to keep motorists and pedestrians safe. After a competitive bid process, Centennial chose Dialight units provided by Traffic Signal Controls, Inc., a Colorado-based Dialight distributor, for their efficiency and affordability.
Dramatic Energy Reduction = Significant Savings
In a two-phase project, fully funded by the EECBG program, the city replaced 1,288 red/yellow/green balls, 142 red/yellow/green arrows and 232 pedestrian countdown timers in Phase One, with the remaining 85 balls, 30 arrows and 1 pedestrian signal changed out in Phase Two.
Replacing the 116W incandescent signals and arrows with energy-sipping 8W LED units and the 59W incandescent pedestrian signals with 6W LED units is predicted to shave 572,000kWh off the city's electric bill, for a total energy savings of $36,000 per year. And, because the LED units will last at least five years-and likely even longer-Centennial expects to save $20,000 in annual maintenance costs by eliminating bulb changes, which also increases safety for signal technicians and motorists by eliminating unnecessary traffic control.
In another sustainability effort, Centennial is converting its school zone beacons to solar power.
"In addition to the energy efficiency, Dialight's products were the most affordable on the market to meet our needs, and the added bonus of the 5-year warranty sealed the deal," Faessler said.
