The coalition is led by the Alliance to SaveEnergy, the American Lighting Association (ALA) and the NationalElectrical Manufacturers Association (NEMA) and includes participantsfrom more than 40 nonprofit energy-efficiency advocacygroups, utilities, lighting manufacturers and trade associations.The coalition has estimated an annual energy saving per householdof up to $100 by replacing less-efficient bulbs with halogen,CFL or LED options. “Understanding which option is best for aspecific application is where LUMEN members can help the homeowner,”said Larry Lauck of the ALA.The website includes a guide to selecting replacement bulbs,frequently-asked questions, and news regarding energy-efficientlighting options. The website also explains the new FTC LightingFacts label, which will be required on all medium screw-basebulbs sold in the US as of January 1, 2012. ◀MORE: www.ledsmagazine.com/news/8/10/23The city of Stamford, CT, has installed over 1000 cobraheadLED fi xtures from GE, leading to an annual saving in energycosts of $146,000. Initially, LED street lights did not farewell in comparison with other products, but the newer GEproducts offered improvements in terms of a color temperatureof 4300K, better uniformity and reduced glare (www. ___ledsmagazine.com/news/8/10/33).DOE consortium publishes LEDstreet-lighting guidelinesThe DOE Municipal Solid-State Street Lighting Consortium hasposted specification templates for use by utilities and municipalitiesthat are evaluating or implementing LED street-lighting projects.The first draft of the Model Specification was posted in Apriland the revised specification takes into account feedback fromconsortium members and the wider community.The Model Specification contains two guidelines and is availableat www.ssl.energy.gov/specification.html. _________________________ The System Specificationoption for municipalities (Appendix A), is designed tomaximize application efficiency and incorporates site characteristicssuch as pole spacing and mounting height. Meanwhile, theMaterial Specification option for utilities (Appendix B), emphasizesluminaire efficiency and does not consider site characteristics.The flexible format of the guideline allows users to modifydefault values to fit their local design criteria, which typicallyvary from city to city, and even from application to applicationwithin a given city. ◀MORE: www.ledsmagazine.com/news/8/10/29_________________________Competition begins for NextGeneration LuminairesThe US DOE has announced that its Next Generation Luminaires(NGL) SSL competition has been separated into two competitions,for indoor and outdoor products, due to growth in participation.Each competition will have its own judging panel, and the datesare now staggered. The intent-to-submit deadline for indoor NGLsis December 16, while final online submissions are due by January13, 2012. Physical product samples are due by January 18, andwinners will be announced in May. The DOE will send out its callfor entries for the outdoor NGL competition in March 2012, withawards being presented in August 2012.The competition is jointly sponsored by the DOE, the IlluminationEngineering Society of North America (IESNA), and the InternationalAssociation of Lighting Designers (IALD). In the NGL SSLcompetition, the judges examine lighted samples in their intendedapplications, as well as photometric data and other documentation.Evaluation criteria include the quality and quantity of illumination,energy efficiency, and serviceability. ◀MORE: www.ledsmagazine.com/news/8/2/27DOE releases promising resultsfrom Round 13 Caliper testingThe US Department of Energy (DOE) has completed Round 13of product testing through its SSL Caliper program. Round 13included three types of products: LED and benchmark high-bayluminaires, LED wallpack luminaires, and LED and benchmark2x2-foot troffers. The summary report provides an overview ofphotometric performance results, compares the results withrespect to similar products that use conventional light sources,and can be downloaded at www.ssl.energy.gov/reports.html.On average, the round 13 LED luminaires showed a significantimprovement in efficacy over LED luminaires tested in 2009 and 2010,with a minimum efficacy close to the average observed in 2009-2010.In addition, the variation in performance across the Round 13 LEDluminaires was less than in 2009-2010 products; that is, there weresmaller differences between minimum and maximum efficacy. A similartrend was observed with other performance parameters includinginitial lumen output, CCT and CRI.MORE: www.ledsmagazine.com/news/8/10/1618 NOVEMBER/DECEMBER 2011 LEDsmagazine.comPrevious Page | Contents | Zoom in | Zoom out | Front Cover | Search Issue | SubscribeqMqM qMM MQmags| Next Page q qTHE WORLD’S NEWSSTAND ®
