LOS LED EN EL MUNDO LED pilot projects get green light in the Big Green Apple.
16 Dec 2009 │ Climate Group launches international LightSavers program Demonstration projects in several cities around the world will evaluate LED lighting while promoting market uptake and encouraging LED-friendly policies and financing. LightSavers, an international program to evaluate the use of LED lighting and smart controls in outdoor spaces, has been launched by The Climate Group at the UN climate talks in Copenhagen, Denmark. The Group’s (see press release describes several other initiatives launched simultaneously. LightSavers will test how LEDs and smart controls perform in real-world applications, while working with its members to plan for scale-up and to encourage LED-friendly policies and financing products. The Climate Group says that LED lamps, combined with smart controls, can cut CO2 emissions by 50 to 70%. LED lighting also reduces costs, enhances public safety, minimizes light pollution and makes public spaces friendlier at night. The program was started by the City of Toronto and the Toronto Atmospheric Fund, which is already running a series of local projects. LightSavers is funded generously by the HSBC Climate Partnership.
The Climate Group is an independent, not-for-profit organization working internationally with government and business leaders to advance smart policies and technologies to cut global emissions and accelerate a low carbon economy. Speaking in support of the LightSavers announcement from the C40 Mayors event in Copenhagen, the Mayor of London, Boris Johnson, said, "London is pleased to be working with The Climate Group to progress trials of energy-busting street lighting to speed up their uptake. “The potential to cut the city's carbon emissions and energy bills with new technologies is huge. By working in partnership, cities have the clout to catalyse the market for greener technologies and drive down procurement costs. We are already taking a series of ambitious yet practical steps to cut carbon in London by 60 per cent by 2025 which includes the installation of 3000 LED traffic lights from 2010." [See News]. More information on the LightSavers program is available at www.theclimategroup.org / programs / leds. Details of the international trials are: New York City, United States The New York Department of Transportation is testing nine LED products in Central Park and on FDR East Side Drive. Toronto, Canada Four City of Toronto agencies are testing parking lot, parking garage, and pedestrian pathway LED lighting products, some with smart controls. London, United Kingdom Transport for London is testing high powered LED roadway lights in demanding applications on their Red Routes. Adelaide, Australia Pedestrian pathway LED retrofit in the northern parklands of Adelaide.
G uiyang, China LightSavers has launched a global trial to test the efficacy and cost savings of outdoor LEDs in a series of cities, beginning with Adelaide, Guiyang, Hong Kong, Kolkata, London, Mumbai, New York, Tianjin and Toronto (see details below). The launch of the New York program was announced in September 2009 – see LED pilot projects get green light in the Big Green Apple.
Hong Kong, China Two municipal universities are testing and comparing Japanese, Chinese, and American made LED pathway luminaries on their respective campuses. Guiyang, China The municipal government is testing two Chinese-made LED street light luminaires, one on a riverside pedestrian pathway and another on a local street (see details below).
Tianjin, China Local government agencies are testing two Chinese-made LED street lights products in a new ecocity development and on a university campus. Kolkata, India The Kolkata Municipal Corporation is testing over a 100 Indian made LED street light luminaries in several locales. Mumbai, India The Thane Municipal Corporation will install a trial of LED streetlights in the Greater Mumbai Region with support from the national government's Bureau of Energy Efficiency.
15 Abril 2009 │ Guiyang, China (Guizhou Province, in southwestern China) The Naming River winds through Guiyang’s downtown and is a major recreational asset for local residents. Many important cultural resources are located along its banks, including the Jiaxiu Lou Tower, and pedestrian paths along both banks are popular with local residents, which are lit along their 8 kilometer length by 150-watt high pressure sodium (HPS) post-top luminaries.
26 Nov 2009 │ Boston trials LED street lights on the Commo. A test installation of acornstyle LED streetlights will enable the evaluation of energy usage and aesthetic impacts. The use of LED lighting for public spaces, sidewalks and roadways is being explored in Boston, Massachusetts, through the installation of a demonstration project on Boston Common, with others proposed across the City. This is part of Mayor Thomas Menino's efforts to "green" Boston. By trying out LED lighting in these demonstration projects and soliciting comments (which can be submitted via www.CityofBoston.gov/LED, the City will be better able to evaluate the technology as well as its aesthetic impacts. The City recently installed LED lights along the “Mayor’s Walk” as part of an effort to showcase the technology and solicit community input. The temporary installation features “acorn” style streetlamps, three each from six different manufacturers. Mayor Menino also announced that the City has joined the national LED City program, an international initiative to deploy and promote energy-efficient LED lighting.
Guiyang, China Guiyang has procured and installed 130 LED luminaires of the post-top variety designed and manufactured by Hiyu in Tianjin, and using Cree LEDs. The new luminaires are rated at 120 watts and produce a warm white light, as well as decorative striations on the pavement. There are two Study Areas, one consisting of 4 baseline luminaires, and the other comprising four Hiyu LED luminaires. Monitoring began in November 2009. Interim results will be available in March 2010.
“This is another great example of our boundless creativity in using new, innovative and cutting-edge technology to stretch the dollar of Boston’s residents while helping to preserve our beautiful environment,” said Mayor Menino. “Programs like this one continue to make Boston one of the country’s leaders in the use of green technology.” The six different styles of “acorn” fixtures were provided by Lumec Lighting, Hadco Lighting, Sternberg Lighting, Osram Sylvania, King Luminaire and Spring City Electrical and will be in place through the end of the year. The City is in the process of identifying sites for temporary installation of “cobra head” style streetlights. Boston operates and maintains more than 67,000 streetlights throughout the City. Much of that light is reflected upward and not directed toward the ground. LED lighting can be “aimed” so as to reduce spillover onto buildings and light pollution into the night sky. Light pollution shines into homes, makes
enjoying the stars, planets and astronomical events more difficult and has been shown to disorient migrating birds and waterfowl. “We’re really pleased that LED technology has been coming down in price and going up in terms of quality and the range of applications,” said Bryan Glascock, Commissioner of the Boston Environment Department. “In the coming months we’ll be working with the City’s Street Lighting Division to find more opportunities to try out LED technology in our neighborhoods.”
rods and cones operate. According to LRC Director Mark Rea, researchers around the world are also concluding that the current system of photometry could use some updating to better characterize light source performance under nighttime conditions. Rea says that the International Commission on Illumination (CIE) will be releasing its own form of unified photometry for outdoor lighting. Saving energy
Boston’s streetlights generate 24,000 tons of carbon (eCO2) emissions annually, which accounts for about 8% of all municipal emissions. Conversion to LED technology would reduce that by about half. In a program begun nearly ten years ago by the Boston Transportation Department, more than 11,000 traffic signals and 1,800 pedestrian crossing lights were gradually replaced with LEDs. As a result, the City saved nearly $400,000 annually in energy costs. LED traffic signals have also been shown to be more effective as the multiple elements won’t burn out all at once and the light is brighter and more intense, getting the driver’s attention more quickly. “Once again, Boston is demonstrating how advanced technology can improve service quality, reduce operating costs, and protect our environment,” said Jim Hunt, Chief of Environment and Energy for the City of Boston. “Deploying this type of innovative technology further enhances Boston’s reputation as one of the greenest cities in LRC method reduces energy consumption of street lighting 05 Nov 2009The LRC says that replacing traditional, yellowish high-pressure sodium lights with cool-white light sources can reduce the amount of electric power used for lighting while maintaining or even improving visibility in nighttime conditions. Researchers at the Lighting Research Center (LRC), Troy, NY, have demonstrated in multiple field tests that, by using what they describe as a Unified System of Photometry, a street lighting system can be designed to reduce energy use while maintaining or improving perceptions of visibility, safety, and security. The Unified System of Photometry provides an objective method for optimizing the spectrum of a light source, while minimizing energy use and at the same time maintaining good visibility. The system was designed to characterize light at any level, including the mesopic level where both rods
LRC field demonstration results from the past few years in rural and suburban areas of Connecticut, Massachusetts, and Texas verified that by implementing the Unified System of Photometry the street lighting system consumed 30 to 50 percent less electric power and the residents believed they could see better and said they felt safer, when compared to lighting systems designed using the traditional system of photometry. There is now renewed interest in the research, according to Morante, as an increasing number of cities and towns across the U.S. are examining ways to save energy either through a reduction or a change in outdoor lighting. The researchers estimate that about half of the approximately 13 million streetlights in the United States have the opportunity to significantly reduce energy consumption by as much as 50 percent, translating to an annual savings of 1 billion kWh, and a reduction in power plant CO2 emissions of 546,000 tons per year. Field studies and references A full report detailing energy use, consumer acceptance and perceptions, visibility, and light levels for one of the LRC’s field tests in the City of Groton, Connecticut, was published last year. In the LRC field studies, the mesopic street lighting system met all utility requirements and, in addition to significant reductions in energy consumption, was preferred by residents over the yellowappearing HPS system. The following selected technical papers explain the Unified System of Photometry: •

01 Oct 2009 │ PG&E rates LED street lighting Pacific Gas & Electric removes a major roadblock for roadway lighting in their new rate schedule, by recognizing the financial benefits of LED technology. A significant obstacle to the adoption of LED street lighting has been overcome, and a milestone has been achieved, through the efforts of Pacific Gas & Electric (PG&E), the California-based utility. PG&E has become the first utility to finally acknowledge and recognize the financial benefits of LED technology, in the development of their new rate schedule "Electric Schedule LS-2 - CustomerOwned Street and Highway Lighting." The schedule can be found on the PG&E website, or the PDF can be downloaded here. The schedule lists the rates charged by PG&E for different lamp types, and is to the sum of the facility charge and the energy charge. Monthly facility charges include the costs of owning, operating and maintaining the various lamp types and size. Crucially, because LS-2 lists LEDs at a separate lamp type, it reflects the energy savings of LED compared to other lighting technologies. LS-2 is applicable to services for lighting installations which illuminate streets, highways, and other outdoor ways and places where the Customer is a Governmental Agency and owns the lighting fixtures, poles and interconnecting circuits. LS-2 was effective May 1, 2009, although it was released several weeks after this date. However, there was no mention of it at this year’s IES Street and Area Lighting Conference (SALC) held earlier this month in Philadelphia, PA, where the announcement would have surely captured the attention of all in attendance, as everyone in the industry has recognized this as a major barrier to overcome.
PG&E leadership has set an example for utilities across North America and created path for municipalities to follow and a vehicle for dialogue and discussion in dealing with their local utility when considering LED street lighting, especially when attempting to derive the associated financial benefits that demonstrate that LED makes ‘financial sense’ in order to develop a realistic payback scenario. Just last week during IIDEX / NeoCon Canada & Light Canada, I had the pleasure to attend a Canadian tour of outdoor LED site lighting hosted by Shirley Coyle, President of RUUD Lighting Canada, when Kevin Orth from BetaLED / RUUD corporate office outside of Racine, WI, apprised me of this significant announcement and removal of a barrier for market transformation. At the DOE R&D workshop in San Francisco earlier this year, Mary Matteson Bryan of PG&E, an advocate of SSL, had discussed the efforts of PG&E in her presentation. Between the efforts of Bryan and David Alexander also of PG&E, along with other PG&E colleagues, this ‘financial acceptance’ of the technology is a revelation for the industry and the municipal end-user. Bryan noted in here presentation that acknowledging LED for its financial benefits was extremely important and that work was underway and nearing completion to rationalize this in the rate schedule, recognizing these benefits in the rates. During the R&D workshop, attendees had the opportunity to tour sites, where LED was been piloted and tested, including the use of adaptive and intelligent technology from Echelon. As more LED is seeing its way to the streets of North America, it is hoped that more utilities see the ‘light’ on the financial benefits in promoting energy conservation and efficiency and follow the lead set by PG&E, a true LEaDer! LEDs MAGAZINE will be bringing you further information on the PG&E story, including interviews with PG&E, the DOE, municipalities and manufacturers to provide a comprehensive understanding of the development of the new rate schedule and to highlight the perspectives of those affected by this landmark release. LEDs MAGAZINE will bring you a recap of both the IES SALC and Light Canada.
17 Sep 2009 │ LED pilot projects get green light in the Big Green Apple New York City has unveiled a trial of LED outdoor lighting products from 9 manufacturers, taking place in Central Park and FDR Drive.
“Energy-efficient lighting is a common-sense approach to tackling global climate change, and New York continues to lead the way as an internationally recognized leader in sustainability.” says Commissioner Sadik-Khan.
The New York City Department of Transportation (NYCDOT) in partnership with international nongovernmental organisation The Climate Group has launched its first LED lighting pilot tests in two of the City’s iconic urban settings, namely Central Park and the FDR Drive expressway. Both locations are under evaluation by the US Department of Energy’s (DOE) Gateway Solid-State Lighting Demonstration Program, whose purpose is to provide independent, third-party evaluation of LED products installed in real-world applications.
Testing LED lights in Central Park
The LED pilot projects are part of NYC DOT Commissioner Janette Sadik-Khan’s continuing plan to develop “world class, sustainable streets” in the City of New York. With help from the Gateway program, the new LED pilot projects will quantify the financial savings and performance of LEDs while visibly demonstrating the improved illumination for Central Park’s 25 million visitors and FDR Drive’s 150,000 daily drivers.
The City of New York is very active in the ‘greening’ of the Big Apple and in exploring opportunities that will achieve this mandate. Rohit Aggarwala, Director of NYC Mayor’s Office for Long-term Planning and Sustainability, said, “Achieving a greener, greater New York will require all City agencies and all New Yorkers to take those steps where they can cost-effectively improve efficiency and the environment in the areas they control.” DOE estimates that LED lighting can substantially reduce energy costs, by as much as 60 percent, compared with existing streetlights. The actual savings achieved always depends on the particulars of the individual installation, including what was installed previously, what product is replacing it and the site details. They also provide a whiter light than the high-pressure sodium (HPS) lights typically used that allows pedestrians and drivers to see more clearly at night.
Press conference to announce LED project Working with The Climate Group and Gateway, the City will gather reliable data on the lifespan, power consumption and lighting performance of 9 different LED products over a 12-month testing period. Products undergoing testing in Central Park include those from King Luminaire, Lumec, Sentry, Spring City and Sylvania, while the suppliers of products on the FDR include BetaLED, eLumen, LED Roadway Lighting and LSI. As part of The Climate Group’s global LED pilot program, a partnership of more than 10 major cities including London and Mumbai, the City of New York is the first participating city to begin pilot testing.
Additionally, as LEDs last longer than the existing lights, so fewer required bulb replacements on roadways like FDR mean fewer lane closures and improved convenience for drivers. The combined benefits of cost, convenience and safety are what the Central Park and FDR LED pilots aim to test. “The opportunity to reduce electricity use across the nation by implementing advanced street and outdoor area illumination technologies like solidstate lighting is tremendous,” stated James Brodrick, DOE’s Lighting Program Manager. “The deliberate, measured process being undertaken by the New York City Department of Transportation is exactly the approach we recommend for other cities considering similar lighting evaluation efforts. LED products are still in a relatively early stage of commercialization, so conscientious and thorough evaluation efforts such as these are essential to
providing invaluable field experience and a current status check on product cost and energy performance.” Dasha Rettew, who leads The Climate Group’s US Cities & Technology Program said, “We are proud to partner with the City of New York on this groundbreaking new LED pilot project. By working with the world’s largest cities, we will establish a series of outdoor LED pilot tests that will unlock critical data, independent from manufacturers, to demonstrate the real-world return on investment, performance and carbon saving benefits of this transformative and scalable clean technology.” Phil Jessup, Global Cities and Technology Director, The Climate Group, said, “LED lighting and smart controls remain relatively untested outdoors for long periods. Our pilots will create a compelling body of verifiable information for cities and businesses looking to cut costs and carbon but still sceptical about how they perform. If LEDs and smart controls can achieve acceptance and scale in large cities, substantial carbon emissions reductions will follow.” Almost two-thirds of outdoor lighting is owned by municipal and regional governments, areas where the Climate Group’s city and state members can have a major impact by driving demand through scaled up LED projects.
The low carbon lighting program forms one key component of The Climate Group’s strategy on the Global Deployment of low carbon technologies that will have a large impact on reducing global emissions if brought to commercial scale. The LED programme is funded by the HSBC Climate Partnership. As one of its aims, the five-year, $100 million partnership works to realize cleaner, greener cities across the world.
28 Aug 2009 │ I-35W bridge LED lighting described in DOE Gateway report. The latest report from the DOE’s Gateway program looks at the first installation of LED lighting on a major interstate thoroughfare in the US. The U.S. Department of Energy (DOE) has published the first report from a demonstration of LED roadway lighting on the I-35W bridge in Minneapolis, Minnesota. The project represents the first installation of LED lighting on a major interstate thoroughfare in the United States. This Gateway demonstration report provides an overview of initial project results including lighting performance, economic performance, and potential energy savings. Key findings to date include:
Founded in 2004, The Climate Group is an independent, not-for-profit organisation working internationally with government and business leaders to advance smart policies and technologies to cut global emissions and accelerate a low carbon economy. Relative to the NYC announcement, The Climate Group is coordinating a global series of pilot projects designed to demonstrate the business case for LED lighting to city decision makers, with the aim of scaling up the global market for the technology.

LED lights on FDR Drive
The LED luminaires provided a notably uniform illumination and offered a conservative 13% energy savings relative to the baseline HPS system. Sufficient illumination levels across the wide span of the bridge were more easily met during LED luminaire simulations than with the traditional HPS system. The luminaires' 40-foot mounting height and wide coverage area necessitated the use of large LED luminaires with correspondingly high first costs. Simple payback was found to be quite long at current luminaire pricing. Overall public reaction to the LED bridge lighting has been very positive, with “positive” comments outweighing “negative” comments by about five-toone.
DOE will continue to monitor the project over the next three years, and a final GATEWAY report will be published at the conclusion of this project.
21 Aug 2009 │ The word on the street from the IESLED technology will shine at the forthcoming annual Street and Area Lighting Conference, writes Brian Owen. What a difference a year makes when looking at the transformation of outdoor lighting and the industry's pre-eminent showcase itself, the IES Street and Area Lighting Conference (SALC), to be held next month in Philadelphia at the Loews Philadelphia Hotel from September 13-16. After attending this conference for 3 years, I can readily see the advancements, not only to industry and the technology but also to the attendee interest, sector involvement and the mindset towards the acceptance and adoption of SSL in street and area lighting, both in the private and public sector. While in 2007, we were at the leading if not bleeding edge of the introduction of the technology in these applications, products on the exhibition floor were 'light' to excuse the pun, in fact even lightweight compared to the advancements and far more robust performance of today, as well LED was not a topic of great discussion, rather still a 'taboo' of the day. A very noteworthy presentation was given in 2007 by Mark McClear of Cree, in which he highlighted the state of solid-state and provided a roadmap of what was ahead. Mark, a regular presenter to industry conferences, will again offer his insight this year in a presentation entitled "LED Reality Check". As always, things are changing rapidly in LED technology with new brightness and efficacy levels, cost breakthroughs, installations, and standards development. Mark's presentation will cover the changes and developments in the last 12 months and give some ideas of what to expect in the future from this increasingly important light source. McClear will also co-present a full day workshop on "LED Specification and Design Fundamentals". Dawn Midtbo, Manager of Sales & Marketing at Intolight, a division of Puget Sound Energy and Chair of the IES Street and Area Lighting Committee invites everyone to attend this 28th annual conference reflecting that “Last year’s conference in Denver was very well attended and we expect to offer the same top quality presentations in Philadelphia. This conference is a great opportunity to network with many hundreds of your peers, attend presentations by leaders in our industry, and walk an extensive exhibition area where all of our leading manufacturers will be happy to discuss products and trends.”
She added, “This is the only conference in North America that specifically targets the needs and concerns of the street and area lighting industry. You will find that the conference is keyed around issues that concern us all no matter what your particular interests may be, and you will certainly not lack for opportunities to both listen and be heard. These are very exciting times! So many advances in the various sectors of outdoor lighting are daily demanding our attention. So many new market and environmental requirements with which we must all deal are being constantly mandated.” With respect to the value in attending, Midtbo commented, “Our industry is changing and progressing so fast that it’s hard to keep up. It may well be that this conference is your best opportunity to both update and measure your knowledge.” The IES also notes the opportunity to network with your colleagues and apply real solutions to your business challenges, while learning about the latest new products and services from the industry’s leading suppliers as reasons to attend and that all courses and sessions are approved for Continuing Education Credits. New to the pre-conference workshops this year is LED Specification and Design Fundamentals, a full day workshop that will start with the basics of LED technology and explain how this new light source interacts with the driver, thermal, and optical interfaces of the LED luminaire system. Topics such as retrofitting existing designs vs. a total replacement; real, attainable, energy and Total Cost of Ownership (TCO) savings vs. HID systems will be addressed. The evolution of new standards including IES LM-79 and IES LM-80 will be covered along with photometric implications of LED vs. HID sources. Mark McClear of Cree and Perry Romano of Beacon Lighting will lead this course. Jim Brodrick, Manager of US Department of Energy Solid State Lighting Program will deliver the opening address, "Trends and Future Outlook." Drawing on key partnerships with IES, industry, standard setting organizations, energy efficiency groups and utilities, the DOE has developed a wide array of collaborative programs designed to provide the information and tools needed. Brodrick will discuss how these programs can help separate the wheat from the chaff, and how attendees can get involved and accelerate their learning curve.
Ron Gibbons from the Virginia Tech Transportation Institute will present on Mesopic Vision and White Light Design, as well as Color Conversion. Extensive work has been performed to measure the performance of alternative light sources in roadway lighting systems. Gibbons will discuss this in relation to the measurements and the results from the work performed in Anchorage, San Diego, Hawaii and at dedicated test facilities. These measurements include illuminance, luminance and human response. Gibbons will also discuss the comparisons of light sources, performance and some recommendations for design standards including the impact on mesopic lighting. Federal Energy Bills have passed in 2005 (EPACT) and 2007 (EISA) that affect lighting systems. The streak of odd-year energy bills continues with the introduction of the 2009 Energy Bill also known as the American Clean Energy and Security Act (ACES). The proposed 2009 bill may prove to have biggest effect yet on outdoor lighting systems. There is ongoing debate on the outdoor lighting system provisions in the 2009 bill. Joseph Howley, Manager of Industry Relations at GE Consumer and Industrial Lighting will discuss how legislation will affect outdoor lighting decisions. Solid-State Plasma Lighting products available today offer compelling advantages over HID and LED alternatives in energy usage and total cost-ofownership for those high-output lighting applications that need compact, high CRI sources and low maintenance. Apurba Pradhan, Senior Product Marketing Engineer, Luxim Corporation will review application highlights of market-ready products and lay-out technology roadmap that enables low total cost-of-ownership needed for rapid payback periods in street and area lighting installations. The conference will also showcase the artistic and creative approach to lighting in presentations entitled 'Bridges as Gateways to Cities' and 'Avenue of the Arts Façade Lighting', highlighting local Philadelphia lighting projects. In a presentation entitled, 'What We Do Know Can Hurt Us', David Keith, Principal of Marshall Design will discuss what is currently known about the impacts from different light sources, focusing on non-economic issues and consideration of source color. Information and opportunities in outdoor lighting continue to grow, producing surprising and important developments, however, the realities of physics and markets may be in conflict with longterm objectives such as reducing the environmental
economic issues and consideration of source color. Information and opportunities in outdoor lighting continue to grow, producing surprising and important developments, however, the realities of physics and markets may be in conflict with longterm objectives such as reducing the environmental impacts of exterior lighting. Keith's wisdom will take attendees through this thought process. Carl Andersen of the US Federal Highway Administration will present 'Lighting of the St Anthony Falls Bridge – One Year Later’; provide an overview of the lighting performance over the first year of operation. The St Anthony Falls (I-35W) Bridge in Minneapolis, MN, is considered the first application of an LED-based roadway lighting system in the U.S. A team comprised of the Minnesota DOT, US DOE, US FHA, and BetaLED, with the assistance of the Virginia Tech Transportation Institute (VTTI), is monitoring the performance of this groundbreaking lighting system. One would have to see it to believe it, but Ron Gibbons has certainly answered the question of light measurement in difficult to access spaces such as bridges with the VTTI mobile unit the can take light measurements with a dynamic, not static, luminance camera system ‘in motion’ and not require bridge or road closures. Nancy Clanton will present ‘A Tale of Two Cities and Their Quest for Energy Efficient Street Lighting’. As energy and maintenance costs begin to sky-rocket, outdoor lighting has recently been targeted as a huge potential in cost reductions. In addition, the impacts of outdoor lighting on circadian cycle disruptions, nocturnal animal habitat, light trespass and sky glow have also been hot topics. Clanton will present case studies how two cities performed visibility tests and community subjective evaluations in order to assess the best street lighting replacement solutions. Of interest to municipalities, the presentation ‘Municipal and Utility Funding for Emerging Technologies’ will demonstrate the status of a newly launched budget assistance and rebate program facilitated by a utility for the benefit of the end customer, in this case being the municipality as the ratepayer and the taxpayers as a whole, resulting in realized energy savings. The control and monitoring of outdoor lighting offers cities, streetlight maintenance companies, and utilities the prospect of lower operating costs, longer asset life, and more favorable environmental impact. Peter Hochstein, President and CTO of Relume
Peter Hochstein, President and CTO of Relume Technologies will present a novel solution and discuss the economic and technological challenges that remain. Using case studies from several cities, including Philadelphia, the presentation, ‘Pedestrian Lighting in the Urban Master Plan’ will demonstrate the impact that a more pedestrian approach to lighting can have on the economic success of a downtown area. As mentioned in a recent interview with Peter Strasser of the International Dark Sky Association (IDA) Lighting and Human Health is a hot topic as light is a stimulus for regulating hormones, circadian rhythms and behavioral responses in humans. Recent research indicates that these nonvisual effects of light are mediated by a newly discovered photoreceptor in the eye that is distinct from the classical rods and cones for vision. Dr. George Brainard, Professor of Neurology and Director of the Light Research Program at Jefferson Medical College, Thomas Jefferson University will provide up-to-date findings on this physiology, and its potential relevance to putative health risks of street and area lighting.
An attendee and exhibitor for years, Dr. Robert Adams of Chips and Wafers has his own perspective on the LED acronym being Lies, Exaggerations and Denials. The industry and the technology are getting better but some of the practices still are not. As the DOE’s Jim Brodrick stresses, do the due diligence. I can take the point one ‘step’ further as it is better to ‘do due’ than to step in the ‘do do’! In 2008, Nancy Clanton exclaimed, “You have endured how many days about LEDs?” Nancy is the penultimate professional in her work and regarded as tough in her overview of the technology, but fair and an excellent steward to have in the process of bringing the technology to market. 2008 saw an attendee reaction of bewilderment, confusion with the onset of LED, even somewhat uncomfortable but in most cases because of the concern as to meeting performance and standards requirements, which is now coming to fruition. Rumour has it that even Mark McClear may have a different perspective on LED retrofits for outdoor luminaires in his presentation this year.
An overview of US DOE efforts to advance energy effectiveness in lighting parking lots and parking structures through a mass procurement project will be presented by Michael Myer, Research Analyst at PNNL. Myer will highlight lessons learned from both developing the procurement specification and from recent demonstrations of the technologies in the specification.
With the new DOE Energy Star criteria for outdoor lighting applications currently in the comment stage, including the new metric ‘Fitted Target Efficacy’ or FTE, there will be much discussion surrounding standards. Municipalities are encouraged to join in on this process and to attend the SALC. With the onset of ARRA (stimulus) projects that involve Led in street lighting throughout the US, it behooves municipalities to use the SALC and other IES resources as a part of their due diligence process.
A Panel including Jim Brodrick, Nancy Clanton, Rick Kauffman and Rita Harrold, IES Director of Technology will present an overview of the latest pertinent lighting documents to the IES Lighting Library, included updates on RP-8, LM-79 and LM80, as well as a report on the newly formed IES Mesopic Lighting Committee.
Following the SALC, the IES Roadway Lighting Committee (RLC) will meet for 3 days to review activities, technological progress and standards development. Brian Owen and Shirley Coyle of BetaLED / RUUD will be introducing an LED education curriculum outline. Those in the industry are encouraged to inquire about and join the RLC.
Valerie Landers of the IES reports that as always, the exhibit floor is at a premium and once again a total sell out. Attendees can review over 40 application specific exhibitors, with most now having LED based products in their lines. Valerie Landers has been instrumental in the development and progress of this conference and the many other duties in her portfolio at IES. Some of the most ‘brilliant’ minds in the lighting industry, such as Nancy Clanton, Ron Gibbons, David Keith, Ian Lewin, Mariana Figueiro and Bill Smelser continue to shine their light on presentations over the history of the SALC, many on this year’s program.
Join the IES for the latest from the ‘street’ at this year’s SALC. LEDs magazine will be there to bring you the latest news on SSL in outdoor applications and standards development. For more information about IES SALC, contact Valerie Landers at 212.248.5000 x117 or visit www.ies.org.
