TORRANCE, CA --   Energy-efficient T8/bi-pin LED lighting tubes are the latest fluorescent-replacement LED lighting products LEDtronics announces adds to its green-technology lineup.

LEDtronics
® series LED48T8-288-001W bi-pin LED fits into standard G13 bases and is designed to directly replace conventional T8 fluorescent tubes that provide general lighting for commercial, residential and architectural lighting applications. The 48" long white tubes provide the equivalent light output of 24 to 32-watt fluorescent lamps while consuming less than a maximum of 19 watts. In addition, the LED48T8 tubes run on a wide voltage range of 100 to 290 volts AC.

When it comes to rated life, the LEDtronics series LED48T8 really shines.

50,000 hours and more!

While conventional fluorescent lamps typically have a rated life in the range 8,000 to 24,000 hours, the LED48T8 lamps boast an operating life of 50,000 hours and more -- 5.7 years of continuous light. Furthermore, since the LED lights produce so little wasted heat, the temperature inside the fixture does not build up as it does with conventional fluorescent tubes.

The sturdy construction of a UV-resistant polycarbonate housing over the LED tube provides increased protection (no glass to break) and shielding against many environmental effects, allowing them to be placed in locations where typical lights would be more vulnerable to the elements. 

Hot and Cold Temperature Applications

LEDs perform well in temperatures from -35C° to +45C°, making them ideal for applications subject to frequent on-off cycling, such as garages and basements, while the aluminum back cover helps with better heat dissipation and a longer lifetime for the LEDs.

The LEDtronics LED48T8 lights deliver up to 1,342 lumens at a color temperature of 5000K (pure daylight white) and 1,072 lumens at a color temperature of 3000K (warm white), compared to the average 810 lumens for equivalent conventional fluorescent tubes. They provide a brightness of up to 429 maximum foot candela across a 114-degree beam pattern, with an impressive CRI of 80.

Other benefits of LEDs over fluorescents include: Quick and easy installation to minimize retrofit costs; no ballast and starter needed, thus no radio frequency to interfere with radio and television signals; instant, full-strength lightup; no buzzing or flickering; and directional distribution of light--good for interior task lighting.

Solid-state design renders LEDs impervious to shock, vibration, frequent switching and environmental extremes. Savings from reduced maintenance costs and downtime quickly return the capital investment expenditure, making them as friendly to the environment as they are to the operating budget. The positive environmental impacts of LED lights additionally come from the consistent, reduced power consumption, long service life, high-quality light, and cold temperature operation, with the corresponding reduction in greenhouse gases and the reduced waste from fewer replacements. Unlike conventional fluorescent bulbs, LED lights are not disposed of as hazardous waste at end of life.

The LEDtronics LED48T8 tubes comply with RoHS--the lead-free and mercury-free directive, as well as the CE safety assurance. They emit no infrared or ultraviolet radiation, and effectively reduce light pollution, being compatible with the international "dark skies" initiative.

The LED48T8-288-001W Premium 4-ft (1200mm) Tube Lights come in two colors: Warm White (SIW) and Pure Daylight White (TPW). Other viewing angles, tube lengths and a variety of LED colors are available for OEM customers. Large-quantity discounts are available for qualified distributors. Availability is stock to 6 weeks.

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.

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. More information on the report is available by contacting Tim Carli, Sales Manager, at +1 650-941-3438 ext. 23, by e-mail at tcarli@strategies-u.com, or on the company web site, www.strategies-u.com.

A Whiter LED Light Technique

White LEDs show promise as a brighter, longer-lasting and more energy-efficient light source than conventional lighting, such as incandescent and fluorescent lights, which they may replace in the future. But scientists have had difficulty producing white LEDs that are suitable for practical use. Existing technologies produce tinted shades of white light, require complex components, and become unstable over time.


Researchers have developed a new, simpler white LED that shows promise as a more efficient and stable source of pure white light for improved illumination of homes and offices. (Credit: The American Chemical Society)

White-light-emitting single molecules are promising materials for use in a new generation of displays and light sources because they offer the possibility of simple fabrication with perfect color reproducibility and stability. To realize white-light emission at the molecular scale, thereby eliminating the detrimental concentration- or environment-dependent energy transfer problem in conventional fluorescent or phosphorescent systems, energy transfer between a larger band-gap donor and a smaller band-gap acceptor must be fundamentally blocked.

Orange + Blue = White

A new, simpler white LED that is the first to achieve stable white light emissions using a single molecule. Their specially engineered molecule combines two light-emitting materials, one orange and one blue, which together produce white light over the entire visible range. In laboratory studies, the scientists showed that light production from an LED using the new molecule was highly efficient and had excellent color stability and reproducibility, features that make it a practical white light source.

The incandescent bulb is turning into a case study of the way government mandates can spur innovation.

Despite a decade of campaigns by the government and utilities to persuade people to switch to energy-saving compact fluorescents, incandescent bulbs still occupy an estimated 90 percent of household sockets in the United States. Aside from the aesthetic and practical objections to fluorescents, old-style incandescents have the advantage of being remarkably cheap.

"There's a massive misperception that incandescents are going away quickly," said Chris Calwell, a researcher with Ecos Consulting who studies the bulb market. "There have been more incandescent innovations in the last three years than in the last two decades."

The first bulbs to emerge from this push, Philips Lighting's Halogena Energy Savers, are expensive compared with older incandescents. They sell for $5 apiece and more, compared with as little as $ .25 for standard bulbs.

But they are also 30% more efficient than older bulbs. Philips says that a 70-watt Halogena Energy Saver gives off the same amount of light as a traditional 100-watt bulb and lasts about three times as long, eventually paying for itself.

The line, for now sold exclusively at Home Depot and on Amazon.com, is not as efficient as compact fluorescent light bulbs, which can use 75 percent less energy than old-style bulbs. But the Energy Saver line is finding favor with consumers who dislike the light from fluorescent bulbs or are bothered by such factors as their slow start-up time and mercury content.

"Due to the 2007 federal energy bill that phases out inefficient incandescent light bulbs beginning in 2012, we are finally seeing a race" to develop more efficient ones, said Noah Horowitz, senior scientist with the Natural Resources Defense Council.

Some of the leading work is under way at a company called Deposition Sciences here in Santa Rosa. Its technology is a key component of the new Philips bulb line.

The big three lighting companies -- General Electric, Osram Sylvania and Philips -- are all working on the technology, as is Auer Lighting of Germany and Toshiba of Japan.

A third technology, bulbs using light-emitting diodes, promises remarkable gains in efficiency but is still expensive. Prices can exceed $100 for a single LED bulb, and results from a government testing program indicate such bulbs still have performance problems.

That suggests that LEDs -- though widely used in specialized applications like electronic products and, increasingly, street lights -- may not displace incumbent technologies in the home any time soon.

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. My job - and our job as a government - is to do whatever we can to unleash the great generative powers of the American economy by encouraging their efforts. And when you hear the innovation that's taking place - everything from LED lighting that can save a huge amount on energy costs to new concrete materials....that gets you excited about the future."

"With President Obama's support and the current momentum surrounding energy efficiency and sustainability, there are unprecedented opportunities for U.S. companies, like Cree, to deliver innovative technologies and products to address our current energy challenges," said Swoboda.

"22% of US electricity is used for lighting and the widespread deployment of LED lighting can reduce this by more than 60%."

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."

Times Square New Year's Eve Ball is Made with LEDs!

Lighting Science Group Corporation (LSG),   has designed, developed and produced an integrated lighting system for the 2009 Time Square New Year's Eve Ball. The Ball, which boasts a system comprised of 672 LED modules, will be installed on November 26, 2008 in Times Square, New York, where it will continue to remain year round.

The new Times Square Ball is double the diameter of previous Ball and is over 12 feet wide and weighs 11,875 pounds. The Ball uses 32,256 Philips Luxeon Rebel LEDs, which is more than triple the number of LEDs used when compared to the 2008 Ball. The four LED colors, red, green, blue and white, will produce a rich color palette, resulting in 4.3 billion possible color combinations.

This year's Ball is approximately three times brighter and 20% more energy efficient than last year's already energy-efficient Ball. Lighting Science designed and developed the overall lighting system for the Ball, including the LED modules, power systems, and power and data distribution networks. In addition, LSG created custom optical reflectors which extract maximum light output, and an integrated thermal management system that optimizes the balance between brightness and lifetime.

Category B is established as a future target for performance of SSL-based luminaires.  Products cannot qualify under Category B until three years after the effective date of these criteria.  If technology improves faster than expected, and opening category B prior to completion of a three-year waiting period would be in the public interest, DOE will advance the date for allowing products to qualify under Category B.

DOE's intent, is to substantially increase future performance requirements of LED Luminaires, and to encourage continued improvement in technology selection and design of luminaires using SSL sources. Products for a wide range of general illumination applications will be eligible.

The minimum luminaire efficacy target given for Category B is intended to rival today's most efficient lighting systems using traditional light sources.

T8 Fluorescent Lamp and Electronic Ballast Comparisons For example, the best commonly available high-performance T8 fluorescent lamp and electronic ballast systems are rated around 100 lm/W.

High-quality fixtures for these lamp-ballast systems are about 70% efficient, yielding 70 lm/W luminaire efficacy.

Based on current commercially available technology, the Category B level of minimum luminaire efficacy is not achievable for LED luminaires. However, DOE anticipates performance will rise rapidly over the coming years due to on-going progress in LED efficacy, LED high temperature tolerance, power supply efficiency improvements, and luminaire design.

DOE believes a significant number of general illumination products will be able to achieve 70 lm/W luminaire efficacy within three years after the effective date of these criteria.

DOE will monitor the technical progress of the technology, steadily adding additional Category A products in future versions. If technology improves faster than expected, and opening category B prior to completion of a three-year waiting period would be in the public interest, DOE will advance the date for allowing products to qualify under Category B.


SOURCE: Energy Star Program Requirements for Solid State Lighting Lunminaires


Green Directory: SolutionsForGreen.com ~ Certification Programs: GreenJobWizard.com

The ENERGY STAR criteria for SSL Luminaires use  Luminaire Efficacy to establish performance as defined below:

                                     Luminaire Light Output (includes fixture efficiency and thermal effects
   Luminaire Efficacy =                       Luminaire Input Power
 
The ENERGY STAR criteria for non-SSL residential light fixtures (commonly referred to as
RLF) use system efficacy defined as the light output of the lamp-ballast system divided by the
input power measured in a 25°C environment.  Established test procedures for fluorescent
sources support this approach.  However, the program requirements in this document are
based upon luminaire efficacy, instead of system efficacy for the following reasons:
 
Accurate measurement of the LED light source separate from the fixture is often not
possible. 
LEDs typically are integrated into the fixture and not readily removable
without altering the performance of the light source.

LED performance is significantly affected by elevated temperature.  LED devices
generate heat that is typically removed by an external heat sink, which may be
designed into the luminaire itself.  Separating the light source from its heat sink will
significantly impact test results.  There are no standards or test procedures to measure
system efficacy of LEDs.  However, standards organizations are developing a test
procedure for photometric measurement of LED luminaires.  This test procedure is
currently in draft form and scheduled to be final by the 4th quarter of 2007.

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

The California Department of Transportation has been involved with the development of LED traffic signal modules for more than a decade. The recent energy crisis played a key role in speeding up the statewide conversion from incandescent lights to LEDs.

The Institute of Transportation Engineer's Future Directions Advisory Committee (FDAC) was appointed to identify and consider the trends and issues facing the Institute and the transportation profession. The FDAC gathered and reviewed information on transportation issues and identified trends:

  • continuing increase in demand for transportation;
    • Population increases and urbanization increase traffic flows
  • traffic congestion;
    • Progarmmable controllers and LED lights can improve communications and monitor/measure and adapt to traffic congestion
  • transportation programs to help meet air quality and energy goals;
    • Think saving energy, reducing greenhouse gases and reducing wasted mileage on the streets
  • greater mix of revenue sources for transportation;
    • Think BLUE LEDs on traffic signals to identify traffic violations!
  • federal government setting the direction for transportation programs;
    • Think funding...and ubiquitious traffic communications for tourism and travelers
  • operations and demand management taking precedence over increasing capacity;
    • Less is better...especially vehicles on the road.  Less oil consumption, less congestion, less accidents, less infrastructure costs...
  • intelligent vehicle highway systems
    • Programmable systems adapt to changing conditions and can even be predictive and take immediate steps to reroute traffic, etc.

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.

Auxiliary lighting on motorcycles

The "Night-time Awareness - Auxiliary Lighting" bill unanimously passed through the Maryland Senate  and the House in April 2008. This Motorcycle lighting legislation enables the front, rear, and sides of bikes to be illuminated using non-outwardly projecting lights. The bill was publicized to raise awareness for the National Highway Traffic Safety Association's motorcycle awareness week.

"Most motorcycle accidents involving another vehicle, they are almost always the fault of the other vehicle, and usually the comment of the other vehicle is, we just didn't see him."

Police Sgt. Dave Ennis adds that "Anything that adds to the visibility of the rider, I think is a move in the right direction."

A new smokeless lighting technology that is set to replace pressure lamps used by Omena (sardines) fishermen in the 400 million-year old Lake Victoria is now available in Kenya.

Besides being handy for use, LED lighting technology is brighter than pressure lamps and is free from paraffin spillage that has dogged the lake for many years.

Unlike before when fishermen used over five pressure lamps to catch plenty of fish,  new technology now enables them to use only one source of lighting. 

Supplied by Osram Energy Hub, a German based firm, the rechargeable lamps are expected to cut paraffin spillage into the lake by 100 percent once adopted by all fishermen.

The move is expected to protect the aquatic life of more than 500 endemic fish species. Other low power devices such as radios and mobile phones can also be connected this battery box and recharged.

The firm also has complete luminaries such as the Osram O- lamp 2 in 1 which comprises an energy saving lamp that has an integrated battery that is recharged or exchanged at the Hub as a separate unit. 

The firm is collaborating with solarworld AG and the cell phone manufacturer Nokia and plans to cooperate with Siemens to provide water treatment systems after the pilot trial.

Cree Survey Finds Growth of LED Lighting is Escalating

The LED industry is expected to boom on the adoption, deployment and benefits of LED lighting by the end of this year, according to an independent survey conducted at the Hong Kong International Lighting Fair.

The survey, conducted by solid-state lighting components marketer Cree, found that LED lighting will become the most commonly used in offices, parking garages and residential outdoor applications.

The survey confirms a strong global demand increase for LED lighting products. It reveals that, globally, an increased awareness is developing around the benefits of energy-efficient LEDs. According to Cree, this indicates that the adoption trend should continue through to the end of the decade.

The survey found that nearly three-quarters (72%) of the respondents have experienced a growth rate in excess of 20% for LED lighting products in their businesses during the last six months.

Almost two-thirds of the respondents (63%) said that they believed that LED lighting would be accounting for 50% of their sales and installations by 2009.

The respondents expect the LED lighting market to grow within a variety of application areas, with  the highest being:

  • Street and parking at 20%,
  • Indoor residential at 17%,
  • Retail and display at 17% and
  • Office at 15%

Survey respondents represent top decision-makers and lighting manufacturers who attended the 2007 Hong Kong International Lighting Fair, which is the largest lighting show in Asia and the second-largest in the world. Nearly one-half of the survey respondents were from outside Asia, reflecting the survey’s global reach.

“The survey results present us with a clear and positive picture of LED lighting growth patterns and expectations from leaders in fixture design and manufacturing. “The survey also shows an increasing demand for high-quality, energy-efficient LED lighting,” says Cree director of corporate marketing Greg Merritt.

SciWorks has new exhibit space focusing on the cranks, levers and lasers that are behind the basic science of physics.

In the new PhysicsWorks, displays are grouped by concept into mechanics, light and color, electricity, motion and perception.

The beginning of the exhibit starts with simple displays of levers, gears and pulleys, then moves on to flashier kiosks for electricity and lasers.  Sanford explains, "Not everybody is going to be a scientist, but everybody is going to have to deal with it at some point."

They include a room that captures a photo of your shadow on photosensitive material with an LED flashing light and a game that shows off the focused intensity of lasers.


There are also displays that are more like low-impact rides, such as a kid-size gyroscope, where you sit on a bicycle seat, and holding a spinning wheel by its axle, you turn around. That's the same concept used in the space and air industry to keep shuttles and planes straight, Sanford said.

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.

Understanding Power LED Lifetime Analysis

How intuitive graphical data sets help lighting designers accurately predict power LED reliability in different operating environments.


When designing LED-based lighting systems, engineers need to understand LED lumen maintenance and mortality in similar terms to those used when designing with conventional light sources. However, comparable data has been nearly impossible to find. In addition, designers need extra information to predict the lifetime of LEDs under a variety of operating conditions. A number of techniques to predict LED lifetimes have been proposed, but these have not been sufficient to generate the clear and unambiguous data that lighting engineers can use easily. This white paper provides lighting designers with an understanding of a new tool introduced by Philips Lumileds Lighting Company that simplifies the process allowing full flexibility in design options. This one tool provides designers with information that they need to make decisions about product lifetimes, driver constraints, number of LEDs required, and thermal management.

1. Aging and failure modes of lighting sources
2. Established lighting industry definitions of useful life
3. Established LED industry definitions: Lumen maintenance
4. Understanding LED operation and lifetimes
5. Completing the expression for lumen maintenance
6. Designing with B/L data for optimal lighting performance
7. Predicting LED lifetimes

Conclusion
The lighting industry needs LED manufacturers to provide data that is compatible with current design practice. However, this only answers a part of the challenge. LED vendors should also be in a position to provide more detailed information about product lifetimes under various operating conditions. This data allows lighting designers to deliver the best combination of purchase price, lighting performance, and cost of ownership for the life of the product.

From a user’s perspective, this data is most usefully expressed as a combination of B- and Llifetime as junction temperature and forward current are varied. This allows the system designer to make intelligent choices about the number of LEDs required, how they are driven, and the operating temperature.

Every power LED customer should therefore expect their supplier to provide this data as a matter of course, in any combination of B, L, Tj and If values, with clear definitions of failures (e.g. lumen maintenance below specified condition, electrical failures).

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).

LED City Initiative Yields Benefits Beyond Energy Efficiency

When Raleigh, N.C., the first LED City, and Cree, Inc. turned on new  LEDs in the municipal parking garage, people’s opinion of the quality of the lighting improved threefold.

Survey Shows Public Feels Safer in City Spaces Lit by LEDs


Raleigh exchanged the previous garage fixtures and their dull orange light for LED fixtures with bright white light, and people felt safer. The number of respondents who perceived the garage as “very safe” increased by 76 percent after the LED fixtures were installed, according to a survey by Mindwave Research of Austin, Texas.

Cree produces LEDs that provide a new source of energy-efficient light that can serve as the foundation for cost-effective lighting solutions. Lighting Science Group Corporation of Dallas, Texas, supplied the LED fixtures installed in the Raleigh garage.

“LED technology provides a clear benefit to municipal infrastructure, as well as to the citizens it serves,” said Charles Meeker, mayor of Raleigh. “This survey shows that LEDs can do more than improve light quality. In addition to the proven environmental and energy efficiency benefits the city has already documented, the survey shows that LEDs’ bright white light can help improve public feelings of safety in city spaces.”

The survey results showed that the parking garage generated a more positive reaction from most of the respondents after the addition of LED fixtures:

  • Both men and women felt significantly safer post-installation: 74 percent rated the garage as feeling “very safe,” while only 2 percent did not feel safe. These figures contrast with the pre-installation numbers: Only 42 percent felt “very safe” with the original lighting, and 13 percent did not feel safe.
  • The percentage of respondents who gave the garage an overall rating of “excellent” increased by 100 percent. The number of people who rated it as “poor” decreased from 8 to 1 percent.
  • The lighting quality of the garage was “excellent” according to 86 percent of the respondents, a 258-percent increase from pre-installation respondents. The number of people who rated it as “poor” decreased from 18 to 2 percent.
  • The cleanliness of the parking garage was perceived as “excellent” by 76 percent of the respondents, while only 58 percent rated it this way before the LEDs were installed, showing a 31-percent increase.

Raleigh agrees to become the nation’s first LED City.

The LED City initiative focuses on installing LED lighting, based on Cree’s energy-efficient LEDs, throughout the city to save energy and money and boost the quality of life for its residents by using the best lighting technology commercially available. As a result, the city has improved the energy savings and lighting of its municipal city parking facility, the first of a series of projects aimed at delivering the environmental and economic benefits of LED lighting throughout Raleigh’s “living laboratory.”

Research Note:
The two surveys of 200 people each were conducted on behalf of Cree, Inc. by Mindwave Research, Inc. The pre-installation survey was conducted November 11-13, 2006, and the post-installation survey was conducted February 5-8, 2007.

Cree LED Bulb Matches Output of Incandescent Bulb

In September 2007, Cree Inc, announced it had demonstrated light output of more than 1,000 lumens – an amount equivalent to the output level of a standard household light bulb – from a single R&D LED.

Cree’s achievement demonstrates continued leadership in the development of LEDs that can make traditional light bulbs obsolete.

A single-die LED, driven at four amps, produced 1,050 lumens in cool white and 760 lumens in a warm-white version. Efficacy of the cool-white LED was 72 lumens per watt and 52 lumens per watt from the warm-white device. Both LED versions operated at substantially higher efficacy levels than those of today’s conventional light bulbs. Historically, Cree’s R&D demonstrations generally have been commercialized within 12 to 24 months.

“Cree’s XLamp® LEDs are the best-performing commercially available LEDs, but we won’t be satisfied until light bulbs are obsolete,” comments John Edmond, Cree co-founder and director of advanced optoelectronics. “We’ve worked 20 years to achieve lighting-class LED performance, and we still have plenty of ways to advance the technology further.”

Cree Is A Market Leader in LED Technology Development

A North Carolina-based LED research company, LED Lighting Fixtures, announced that it had created the world's most energy-efficient LED light, one that uses 5.8 watts of electricity to create as much light as a 60-watt incandescent lightbulb. And following that news, LED Lighting Fixtures also announced that they are now part of Cree, Inc.

The company is developing a lamp that uses less energy than its current LED fixtures but emits the same amount of light. A federal study by the National Institute of Standards and Technology confirms that the product is the most efficient in the world. It uses 5.8 watts of power, compared with 60 watts for an equally bright incandescent bulb.

According to the National Institute report, the new fixture uses less than 9 percent of the energy consumed by common bulbs and less than 30 percent of that consumed by fluorescent lights. LLF's best existing product consumes 15 percent of the energy used by an incandescent bulb and 50 percent of that used by fluorescents.

Hunter said he hopes to debut the brighter and more efficient lamps by the end of 2008. The first buyers will likely be wholesale distributors, followed by consumers off store shelves by 2009.

The Department of Energy has estimated that LEDs could reduce national energy consumption for lighting by 29% by 2025.

That would save U.S. households $125 billion on their electric bills.

 
Semiconductor-based LEDs use much less power than traditional bulbs, don't contain mercury like fluorescents, and they last for years, sometimes even decades. Recent years have seen very exciting developments in this area, with Orlando, Ann Arbor, Detroit and Taiwan announcing switches of traffic lights to LEDs.

2007's Rockefeller Center Christmas tree in New York will even be lit with the technology -- strung along 5 miles of wire!

Advances in lighting technology have increased in scale and scope lately, as the world takes action on climate change. Last month, General Electric announced that it would close its incandescent facilities as it planned to stop making energy-intensive incandescent lightbulbs in favor of compact fluorescent and LED products.

And governments large and small have been passing bans on incandescent lightbulbs in recent months, including China's 10-year plan and Ontario's five-year plan to ban incandescent bulbs. Several U.S. states and U.S. senators and representatives have introduced legislation ban incandescents domestically.
