150 Hz operating frequency for LED fixtures by DOE challenged

CHALLENGE DOE ENERGY STAR REQUIREMENTS FOR INTEGRAL LED LAMPS

Once Innovations, a Minnesota based research, development and manufacturing company with a firm focus on LED technologies announced today its intent to formally challenge newly finalized ENERGY STAR Eligibility Criteria for Integral LED Lamps.

"We feel that the increase in operating frequency requirements was erroneously based on speculation about visual flicker, which has nothing to do with energy conservation. The new 150 Hz criteria will hinder the introduction of low cost, energy savings AC LED lighting solutions, which is contrary to the goals of the ENERGY STAR program," stated Mr. Zdenko Grajcar, CEO and Chief Technology Officer at Once Innovations.

Grajcar went on to state, "We stipulate that 60 Hz luminous modulation (flicker) is likely to cause certain discomfort in some people. However, the majority of low frequency AC LED systems operate in the rectified mode, which effectively doubles the luminous modulation frequency to 120Hz for 60Hz mains in the United States. Despite many attempts, laboratory investigations have not found statistically significant effects of luminous modulation with frequencies over 100Hz on human performance, health, or comfort. We've collected studies with hundreds of pages of research material that show no evidence other than speculative statistics to support claims that luminous modulation over 100Hz is visible or harmful to human health. This change in frequencies will have a profoundly negative impact on the future of energy efficient lighting in the United States. As such, we feel we have no other choice but to challenge the DOE decision. At the same time, we strongly urge other manufacturers and users of AC LED technologies to do the same. "

"The last minute change to 150 Hz operating frequency raises a stumbling block to new low cost, high efficiency AC LED lighting technology, which promises tremendous energy savings potential in the U.S." added Mr. Craige Thompson, Chief Legal Officer at Once Innovations. Mr. Thompson went on to say, "The increase to 150 Hz appears to be arbitrary and applied in a way that discriminates against new, more efficient LED technologies in favor of other forms of light fixtures. The DOE should examine the relevant facts and articulate a rational connection between the facts and the frequency specification." Mr. Thompson explained, "The electrical grid in the U.S. operates on 60 Hz. Therefore, rectified topologies will operate at 120 Hz modulation. Generating frequencies above 150 Hz is generally much more complex and expensive. Before increasing the frequency requirement to 150 Hz for LED-based fixtures, the DOE should provide an opportunity for notice and comment pursuant to the Administrative Procedure Act."

 
Once Innovations, Inc. is a privately held corporation that manufactures highly differentiated LED lighting using a visionary approach to research and product development - from unique designs with proprietary technologies through final production and distribution. Once was founded in 2008 by current CTO, Zdenko Grajcar, considered a pioneering rebel in LED technology for his remarkably unconventional thinking and relentless challenge to the industry status quo. The Once Innovations technology research, marketing, and product development campus is located in Plymouth, MN United States of America.

Osram Life-cycle Assessment has concluded that "LED lamps are already today more than five times more efficient than incandescent lamps and future technical achievements offer additional potential for the coming years."

Read the LED life-cycle research! The total LCA also shows that the LED lamp is one of the most environmentally friendly lighting products.

The life-cycle assessment looks at manufacturing, usage and end of life realities.

An OSRAM study monitored the life cycle of an LED and an LED lamp. It´s outcome made it clear - LED lamps need less than 2% of their energy consumption for their manufacture - over 98% are used for their task: illuminating the world.

Click here for more information about this study.

The aim of OSRAM Opto Semiconductors' LCA is therefore to analyse the environmental impact of an LED lamp over its entire life and to compare it with a compact fluorescent lamp and an incandescent lamp. The relevant material and energy supplies were determined in detail for all the LED lamp's components and production processes. Apart from a detailed analysis of each individual production stage, for LED chips and lamp housings, for example, these also include all necessary transports such as the transport of an LED lamp from its production site in China to its place of installation in Europe.

Apart from direct input of raw materials, the energy input, materials and emissions associated with the retrieval of resources are recorded. The results allow for conclusions not only on resource consumption and primary energy input but also acidification, eutrophication, the greenhouse effect, ozone depletion and toxicity.

The bottom line is that LED are efficient

In the first LCA, OSRAM Opto Semiconductors show that LED lamps are a genuine alternative to incandescent lamps, even when considering the cumulative energy input and environmental factors.

Often these fundamentally different lamps were compared based on their wattage. Conventional lamps with filaments are way behind diode lamps. A 40 Watt incandescent lamp, for example, can either be replaced by an 8W compact fluorescent light or, for some applications, by an 8W LED lamp, which means an energy saving of 80 percent.

In order to guarantee the comparability of results in the LCA, a lifetime of 25,000 hours was chosen as reference. The latest LED lamp generation (Parathom Classic A55 with Golden Dragon Plus LED) achieves precisely this rating. Therefore, 25 incandescent lamps (OSRAM Classic A 40W) with a lifetime of 1,000 hours and 2.5 fluorescent lamps (Dulux Superstar Classic A 8W) lasting 10,000 hours have to be used for a comparison.

Over 98 percent of the energy used to produce light

The study was done in collaboration with experts at Siemens Corporate Technology, Centre for Eco Innovations and shows that similar to compact fluorescent lamps with LED-based lamps over 98% of the energy used is consumed to generate light. Less than two percent is allocated to production. This has dismissed any concern that manufacturing of LED particularly might be very energy-intensive. In contrast to the primary energy consumption of incandescent lamps of around 3,300kWh, LED lamps use less than 700kWh. The bottom line is that LED lamps are therefore definitely more efficient than conventional incandescent lamps. Apart from this, the ratings that indicate the lamps' effects on the environment are consistently better than those for incandescent lamps. As the efficiency of LED continues to increase, LED lamps will be capable of achieving even better LCA results in future. Three independent experts are currently verifying the findings of the internal study.

A summary of the study is available at www.osram-os.com/life-cycle-assessment.

Five Year Market Advantage Will Be LED Opportunity

Market conditions are right for the LED replacement lamp market to accelerate in the next few years, according to a new market report by Strategies Unlimited, the leading firm covering the LED market.

LED Market Advantages: quality of light, dimmability, controllability, lamp life and environmental cost of ownership.

Dramatic improvements in commercially available LED performance in recent years, as well as significant cost reduction, has made it feasible to design LED lamps to offer comparable lumen output and to compete with other established lighting technologies on the basis of cost of ownership.  

The market is in a state of flux as utilities, energy efficiency organizations and customers look for optimum solutions which save energy, minimize the cost of ownership, and give acceptable quality of light.

Customer Education

Customers are in the process of being educated about comparing cost of ownership rather than the initial price of lamps.

Regulations Drive European Market

Regulations in Europe will ban the 100W incandescent clear glass lamp starting in September 2009, and will progressively ban all inefficient incandescent lamps by 2012 and all incandescent lamps by 2016. The Energy Information and Security Act of 2007 began the process of restricting the sale of inefficient lamps in the US.

Market Opportunities for LED Replacement Lamps

By 2012, with a few exceptions, inefficient incandescent lamps cannot be sold. Although the awareness of these regulations is still weak in the marketplace, they will create market opportunities for LED replacement lamps.

Recognizing the potential of LED technology to save energy, policy makers have been supporting the research and development of LED technology and helping its commercialization.

In the short run, while LED replacement lamps become a viable alternative, regulators are encouraging compac t fluorescent lamps (CFLs).

However, over the next five years the advantages of LED technology over CFL will become recognized, especially with respect to the quality of light, dimmability, controllability, lamp life and environmental cost of ownership.

  • Some well-designed LED lamps already offer effective lumen efficacies that compete with CFLs.
  • The commercial and industrial segments will embrace LEDs to control costs and save energy.
  • The LED lamps will be used for directed light applications, in hard-to-reach places and where the cost of re placement is very high.

Replacement Lamp Market Growth Projected at 107%

Although the market for LED replacement lamps is still in its early stages of development, the lamp revenues are forecast to grow at a CAGR of 107% through 2013.

Strategies Unlimited explores the market potential for LED lighting technology in its latest report titled LED Replacement Lamps--Market Analysis and Forecast, 2009. The report analyzes five LED-based lamp types that are designed to replace lamps that currently populate billions of sockets:

  • A-lamp and globes;
  • PAR and R lamps;
  • MR 16's;
  • candelabra and decorative lamps;
  • linear fluore scent tubes.

The markets for five categories of replacement lamps are analyzed for market drivers and challenges, trends, units and revenues for 2008. The report also offers a five-year forecast for 2009-2013.

LED Replacement Lamps--Market Analysis and Forecast, 2009 is available from Strategies Unlimited at a price of $1,895.

Chuck Swoboda Participates in Presidential Roundtable on American Innovation and Clean Energy Technology

WASHINGTON, D.C., July 2, 2009 --Chuck Swoboda, chairman and chief executive officer of Cree (Nasdaq: CREE) joined President Obama at the White House to discuss the latest developments in energy-efficient technologies. Cree, based in Durham, North Carolina, is a market-leading manufacturer of LED (light-emitting diode) products.

Swoboda and seven other CEOs representing American companies at the forefront of innovation were invited to meet with President Obama to discuss American innovation in areas such as clean energy and the potential benefits to the U.S. economy.

In his remarks following the White House meeting, the President observed, "I just had a meeting with the CEOs of some of the most innovative energy companies in America to talk about growth and progress of a sector that represents a big piece of America's economic future. It's men and women like these who will help lead us out of this recession and into a better future.

LED Lighting Market Gains Momentum

Shifting to LED lighting is a small but fast-growing trend that is redefining the century-old conception of lighting --- replacing energy-wasting disposable bulbs with efficient fixtures that are often semi-permanent, like those used in plumbing.

Studies suggest that a complete conversion to the lights could decrease carbon dioxide emissions from electric power use for lighting by up to 50 percent in just over 20 years.

And in the United States, lighting accounts for about 6 percent of all energy use.

A recent report by McKinsey & Company cited conversion to LED lighting as potentially the most cost effective of a number of simple approaches to tackling climate change using existing technology.

LED lighting was once relegated to
  • basketball scoreboards
  • cellphone consoles
  • traffic lights
  • colored Christmas lights

But as a result of rapid developments in the technology, it is now poised to become common on streets and in buildings, as well as in homes and offices.

Some American cities, including many in California, as well as Ann Arbor, MI., and Raleigh, NC, are using LED street lights and industrial size fixtures to illuminate streets and parking garages.  Dozens more cities and counties, as well as state governments are exploring the savings in maintenance as well as the energy-saving efficiencies. San Jose, Calif., plans to use $2 million in energy-efficiency grants to install 1,500 LED streetlights.

LEDs are more than twice as efficient as CFLs - compact fluorescent lights --  currently the standard for greener lighting.  And the longer life reduces replacement maintenance time, which  can be more of a savings than the bulbs or energy itself.

Unlike compact fluorescents, LEDs turn on quickly and are compatible with dimmer switches.
Fluorescent bulbs also contain mercury, which requires special disposal, and LED bulbs contain no toxic elements, are so small, and last so long that disposal is not much of an issue.

The switch to LEDs is proceeding far more rapidly than experts had predicted just two years ago.

President Obama's stimulus package, which offers money for "green" infrastructure investment, will accelerate that pace, experts say.

More than 4,200 LR24 recessed LED luminaires are planned for installation in Wedge 5 of the Pentagon as part of a major renovation.
In a signing ceremony today at the Pentagon, John J. Kubricky, Deputy Under Secretary of Defense for Advanced Systems and Concepts, and Albert C. Ellet, acting director of the Washington Headquarters Service responsible for overseeing the renovation, signed an intra-departmental Memorandum of Agreement kicking-off the initiative to install LED lighting in the Pentagon.
 

The Cree LR24 luminaires have undergone extensive government testing and business-case analysis, including a preliminary Pentagon installation to meter the fixtures and compare the results to the alternative fluorescent technology.

This independent analysis demonstrated a 22% reduction in energy usage and improved light quality.

  • The business-case analysis yielded a payback of less than four years.
  • The payback analysis considered energy savings, lifetime maintenance savings, savings from reduced load on the HVAC system, and elimination of hazardous waste disposal fees for mercury-laden fluorescent bulbs.
  • Extensive modeling was also performed to determine optimal lighting design--analyzing the light distribution and spacing to ensure superior lighting and energy efficiency.
  • The Wedge 5 installation is estimated to save 140 tons of CO2 emissions per year.

"The U.S. federal government is taking a leadership role in energy efficiency for federal buildings both through existing mandates, as well as President-elect Obama's American Recovery and Reinvestment Plan, which calls for the renovation of public buildings to make them more energy efficient," said Chuck Swoboda, Cree chairman and chief executive officer. "Installations of highly efficient, low-maintenance LED lighting, like these in the Pentagon and in the U.S. Federal Reserve, demonstrate that the future of energy-efficient lighting is here today."

The LR24 units being used for the Pentagon renovation are being purchased from Cree by the Department of Defense's (DoD) Title III program as a part of its ongoing development program with Cree, and provided to the Washington Headquarters Services (WHS), which oversees the Pentagon renovation program.

"The Title III program has long supported the development and deployment of SiC substrates and devices for use in high-power RF and power-switching applications for DoD systems," said John Palmour, Ph.D., Cree co-founder and chief technology officer for advanced devices. "The program realized the importance of ensuring a strong domestic supply of SiC substrates and related devices, and the potential growth of solid-state lighting in the U.S. This Pentagon lighting project is a perfect example of stimulating America's leadership in high-technology manufacturing yielding unique commercial and defense products, while saving energy. Title III funding was also used to develop the technology in Cree's lighting class XLamp® XR-E LED platform--the light source in the LR24 recessed LED luminaire."

LED lights in Supermarket Refrigeration Gets Cheaper!

DOE found that LED lighting systems enable big energy savings in supermarket refrigeration and have been getting cheaper every year.

LED system prices dropped 9% in 2008 alone and DOE's Solid State Lighting Research and Development Program projects they will fall by 50% by 2012.

In preliminary analysis released in August 2008, DOE showed that, assuming a 50% decline in LED prices, the highest standards would make sense for all supermarket refrigeration systems and would save purchasers $5 billion in net savings over 30 years.

However, for the analysis underlying today's standard, DOE rejected its own LED price estimates, instead assuming that LED prices will stay at 2008 levels forever.

Efficiency of LED Lighting vs Incandescent, etc.

Efficiency Benefits Up to 82% in Energy Savings!

According to Flex Your Power, documented studies have proven the energy savings potential of LEDs:

  • Replacing a red incandescent traffic signal head with a red LED unit cuts energy use by an estimated 82 to 93%. The use of LED traffic signals in cities can save 1 million kilowatt-hours (kWh) of energy and nearly $70,000 a year for every 100 signaled intersections replaced. The payback period is approximately two-and-a-half to three years through energy savings alone.

  • There are 100 million exit signs in the United States containing incandescent lamps that consume a total of 20 billion kWh of electricity per year. LED lighting could save approximately three-quarters of this energy. By purchasing 1,000 exit signs for an initial investment of $30,000, a state government could save a net $455,562 over the products’ lifetime. The new signs would pay for themselves in six months.

  • LEDs can replace neon, offering an 80% electricity efficiency improvement.


The benefits of LED lighting technology go far beyond reducing electricity consumption.

Even with a higher initial investment, dollar savings and quality improvements significantly outweigh costs.

LED technology's numerous benefits also include:

  • Long life and reduced maintenance cost
  • High quality light output
  • Increased safety as a result of LED's lower voltage
  • Smaller, flexible light fixtures
  • Increased durability (no filament to break)
  • Lower lighting infrastructure load and cost for expansion

Anchorage Extends Daylight with LED Street Lights

Anchorage Mayor Mark Begich announced his city’s participation n the LED City® program, an international program that promotes the deployment of energy-efficient LED lighting. This initiative is in conjunction with an energy-related effort calling for the retrofit of all 16,000 municipal roadway lights with high-efficiency LED fixtures.

“I am pleased to announce the appropriation of $2.2 million to enable the city to purchase LED fixtures to change out roughly one-quarter of Anchorage’s streetlights,” notes Mayor Begich. “We have studied new lighting technology extensively over the past several months to validate energy and maintenance cost savings. We also conducted a lighting conference and public survey in March of this year that showed our residents overwhelmingly approve of the new white LED lighting. With this feedback and quantified costs savings research in hand, we are confident in moving ahead with the broad deployment of LED lighting for our roadways.”

The continental US has more than eight hours of daylight per day. Here in Anchorage, approximately 85 days a year we see less than eight hours of daylight.

“Lighting is absolutely critical to daily life in Anchorage. The continental US has more than eight hours of daylight per day. Here in Anchorage, approximately 85 days a year see less than eight hours of daylight. It is significant that this community is at the forefront of adopting energy-efficient lighting,” notes Deb Lovig, Cree LED City program manager. “Cree and the other LED Cities welcome Anchorage into the program and look forward to learning from this large-scale installation as the city pushes forward for energy and maintenance savings with LED lighting.”

The LED fixtures from BetaLED are expected to use 50-percent less energy than current streetlights, which could save the city $360,000 annually at today’s energy prices. The LED fixtures, based on performance-leading Cree XLamp LEDs, typically last up to seven times longer than high-pressure sodium fixtures, allowing Anchorage to better utilize maintenance resources.

Despite a slumping economy, new store venue is seen as smart strategy by a lighting store in Fort Myers, FL.

The roughly $3 million building will offer a host of improvements over the current location, including a two-story atrium for grand chandelier displays, light lifts in the ceiling - a motorized apparatus that allows chandeliers to be lowered to eye level - and a customer service area separate from the showroom.

LED Signage Attracts Consumer Traffic

The exterior will be highlighted by a roughly 35-foot-tall electric sign with a 9-foot by 14-foot LED screen that can be used for advertisements and demonstrations.

In response to the downturn, the Bebbers have tightened their credit policies, reduced overhead through such things as cutting energy usage by using fluorescent display lighting and dramatically increased retail advertising. The additional advertising has meant a boost in retail trade over the past year, as has a moving sale that began in January.

Sector Marketing Strategy Shifts to Consumer Remodeling

"We felt a lot of people would keep their money and turn to remodeling and home improvements, so we started marketing to them to try and make up for the lack of the volume-builder business," Chuck Bebber said.

Today, retail customers represent about two-thirds of the store's business, a position commercial customers occupied before the advertising blitz.

According to the Federal Highway Administration, in 2000 there were 106,000 crashes from running RED LIGHTS, with 89,000 injuries and 1,036 deaths.

Blue lights above traffic signals  are called "tattletale lights" or "red light confirmation lights." Whenever the traffic signal is red, the blue light is on.

Police previously had to testify that a vehicle was in an intersection when it ran a red light.

Now, officers only have to see the blue light to know the vehicle ran the red signal.

Florida Department of Transportation officials are paying for the lights at intersections on state roads in nine Central Florida counties, reported a representative from the Florida Department of Transportation.

Originally, the DOT put up small white lights at a cost of about $100 each. The DOT is switching to less-expensive blue lights, which are LED (light emitting diodes) that run cooler and need less maintenance.

Running a red light in Florida can bring a fine of $188.50.

Violators also face adding three or four points to their driving record, unless they complete a state-approved driver-safety course.

LED Christmas Lights Save Cities on Holiday Displays

In two recent articles the Daily News reported that the city of Fairbanks, Alaska spent over $880,000 dollars on electricity each year.

HolidayLEDs.com an online retailer specializing in LED Christmas lights and LED decorative lighting is offering to donate energy-efficient LED Christmas lights to the City of Fairbanks to help the city in its efforts to reduce its energy consumption.

News Image

I read an article in the Fairbanks Daily News-Miner about the Cities' efforts to reduce its energy consumption and decided we would offer to help
"I read an article in the Fairbanks Daily News-Miner about the Cities' efforts to reduce its energy consumption and decided we would offer to help," said Philip C. Curtis, President of HolidayLEDs.com.


Fairbanks city engineer, Mike Schmetzer, and his energy task force were reported to have set out to figure out how the city could reduce its energy costs. Some of the proposed solutions of the task force including turning off non-critical streets lights and eliminating Christmas light displays.

"Its commendable that the City of Fairbanks is taking a serious look at its energy consumption--we should all be doing this--but Christmas lighting displays are such an important part of the Christmas celebration it would be a shame if the residents of Fairbanks had to eliminate this tradition," Curtis added.

LED Christmas lights are 80-99% more efficient than standard incandescent lights and substantially reduce the cost of operating a holiday display.

"If Fairbanks replaced its incandescent lights with LED Christmas lights the amount of power consumed would be de minimus and we'd like to help the City make the switch by offering to donate four cases of lights to the City," Curtis explained.

Curtis' company shipped a substantial number of LED Christmas lights to the State of Alaska in 2007. "The residents of Alaska have been good customers to us and we are glad that this opportunity arose to help the citizens of Fairbanks," Curtis concluded.

D.Light, a startup officially announced its products in June 2008.

The company is in the process of moving its offices to Shenzhen, China, from Mountain View, Calif., to manufacture three LED and solar-based lighting products that cost just $10 to $30 and are meant to replace kerosene lanterns.

The Nova will sell for approximately $12 to $25 and one hour of solar charge can provide one hour of LED light on the medium setting.
 
In many regions of India and Africa that are not connected to the electric power grid, kerosene lanterns provide much of the lighting. But kerosene lanterns can be unsafe and cause respiratory problems; they’re also generally pretty dim and are a contributor to greenhouse gas emissions.

D.Light President Ned Tozun tells us that, while no one would argue replacing kerosene lanterns is a bad idea, technologies such as LEDs and solar panels have just started to become cost-effective replacements.

D.Light was founded by Tozun and his business partners at Stanford with  backing from Draper Fisher Jurvetson, Garage Technology Ventures, Mahindra & Mahindra, Nexus India Capital, Acumen Fund, Gray Matters Capital and Michael Marks (the Chairman of Flextronics). D.Light is working with Seoul Semiconductor for its LEDs and plans to produce in “the millions of units” and strongly focused on getting its goods to the developing world first.

In 2007, Philips Lumileds released the LUXEON K2 warm and neutral white LEDs that offer new lighting possibilities

Warm-white and neutral-white LUXEON K2 emitters and a LUXEON K2 Star part  can be specified with any standard white emitter.

The new white colors have typical correlated color temperatures (CCT) of 3000K and 4100K and a color rendering index (CRI) of 80 and 75 respectively. The CCT range for LUXEON K2 now extends from 2670K to 10,000K and a new finer color bin structure allows for better overall selection.

Unlike most power LEDs that are limited to 700mA, LUXEON K2 warm white and neutral white LEDs can be run up to 1500mA and a junction temperature of 150°C. The new warm-white and neutral white can deliver more than 130lm and 140lm respectively. LUXEON K2 delivers more usable light at virtually any drive current and junction temperature condition.

“With the increases in light output performance and efficacy, there is expanding demand for power LEDs that deliver the quality of light required for general lighting applications,” said Steve Landau, Director of Marketing Communications. “Designers of residential applications, such as recessed can lights need uniformity, high color rendering and a warm white color temperature at 3000K. In many retail and commercial applications, a cooler temperature of 4100K is desired. With the new binning and phosphor technologies in LUXEON K2, the needs of lighting designers in both markets can be addressed.”

Lighting designers consider several critical “quality of light” factors when evaluating white LEDs: color temperature (CCT), color rendering (CRI) and color uniformity are three of the most important. The new LUXEON K2 parts address CCT and CRI and Philips Lumileds phosphor expertise and technologies ensure the highest degree of color uniformity resulting in white LEDs that are as much as 7 times more uniform that other white power LEDs.

In 2007 Cree and Raleigh, North Carolina, Launch Nation’s First “LED City” with Cost-Saving Municipal Lighting

Raleigh Recognizes Greater than 40 Percent Energy Savings as Municipal Garage Switches to LED Lighting.

Cree, Inc., a U.S.-based leader in LED solid-state lighting components, and the City of Raleigh, North Carolina, the anchor city in a rapidly growing metro area, developed a joint, city-wide initiative to test, deploy and promote LED technology focused on a variety of general lighting applications.

The “LED City” initiative will create a “living laboratory” to deliver the economic, environmental and usage benefits of LED lighting to the urban residents.

The first project is focused on validating both the cost savings and technology capabilities of LEDs through an installation of LED lighting in the City’s Municipal Building parking deck.

Both Cree and Raleigh public officials expect the initiative to serve as a model for other cities that are considering implementing energy-efficient infrastructures.

As part of the commitment to creating an “LED City,” Raleigh plans to deploy LED lighting, through its living-laboratory initiative, to serve a number of lighting applications over the next 18 months including:
  • garage and parking lot lights
  • street lights
  • architectural and accent lighting
  • portable lighting
  • pedestrian and walkway lighting

Cree, the City of Raleigh and Lighting Science Group Corporation (OTCBB: LSGP) of Dallas, TX, also announced initial results of the first installation of the LED City initiative. LED-based lighting fixtures, provided by Lighting Science Group, were installed by Amtech Lighting Services in the Raleigh Municipal Building parking deck in December 2006. Progress Energy, Raleigh’s primary electric utility provider, says the floor equipped with LED lights uses over 40 percent less energy than the standard lighting system. Plus, according to Progress Energy’s research, the quality of light in the garage is greatly improved.

“The economic benefits for municipalities to invest in LEDs are clear – they

  • save energy
  • reduce environmental impact
  • improve the quality of light
As leaders in one of America’s fastest growing cities, it’s our civic responsibility to invest in the future and ensure the highest possible quality of life and safety for our citizens in generations to come,” stated Charles Meeker, Raleigh mayor. “We believe that the cost savings and benefits of LED lighting are real and achievable today.”

“Today’s announcement represents a milestone toward large-scale adoption of clean, energy-efficient technologies,” commented Kateri Callahan, president of the Washington, D.C.-based Alliance to Save Energy (ASE).
“Raleigh’s progressive commitment to becoming the first ‘LED City’ will no doubt serve as a model for other cities seeking to improve energy consumption and reduce negative impacts on the environment. We commend Cree and the City of Raleigh for helping support our mission of achieving a healthier economy, a cleaner environment and greater energy security.”

“The City of Raleigh is willing to set the pace, and we invite other municipalities to join us in developing energy-efficient civic centers,” said Chuck Swoboda, Cree CEO and chairman. “This leading-edge effort establishes an important driver for LED adoption within the United States.”

Cree is using its headquarters facilities as a testbed for LED implementation. 

They are converting all lighting at its Durham headquarters and manufacturing facility to LED lighting and released the results of the first phase of the conversion. The parking lots, entryways, lobby and conference rooms at Cree's headquarters building are now 100-percent lit by energy-efficient, environmentally friendly XLamp(R) LEDs.

Cree's LED Workplace(TM) conversion validates the energy savings, quality of light and reality that LED lighting is now a viable option for business and residential consumers.

In a study of the energy usage before and after the lighting conversion, Cree confirmed the energy savings of the newly installed LED lights.

The findings indicate that in total the new LED lights use 48% less energy than the incandescent, fluorescent and high-pressure sodium lights they replaced.

The combination of the energy savings, reduced maintenance and disposal costs and the environmental savings demonstrate that LED lighting is now a real alternative to traditional lighting solutions.

Duke Energy Collaboration

Cree's local utility, Duke Energy, is collaborating with Cree to explore the benefits of LED lighting. "Our customers are always interested in understanding how to save money through energy efficiency, so we make it our business to support innovative technologies such as LEDs," said Ted Schultz, Duke's vice president of energy efficiency.

"We expect our energy efficiency plans to be approved next year (2008) and are committed to having a complete line of lighting solutions available for customers," said Schultz. "At that point, we expect to have programs developed that will take advantage of LED technology."

"Conventional wisdom is that LED lighting is years away from widespread adoption. The truth, however, is that the performance of Cree's LED technology enables real LED lighting solutions today," said Chuck Swoboda, Cree chairman and CEO. "The conversion of Cree's site demonstrates that the LED Lighting Revolution is well underway and will illustrate the benefits in energy savings, maintenance costs and environmental impacts."

Cree also announced that it has launched a new website to share the results and implementation details of the LED Workplace lighting conversion with other organizations.
