  • Et Lighting Technology Comparison
    Street lighting technology comparison Street lighting today Today, street lighting commonly uses high-intensity discharge lamps, often HPS high pressure sodium lamps . Such lamps provide the greatest amount of photopic illumination for the least consumption of electricity. However when scotopic/photopic light calculations are used, it can been seen how inappropriate HPS lamps are for night lighting. White light sources have been sho wn to doub le driver peripheral vision and increase driver brake reaction time at least 25%. When S/P light calculations are used, HPS lamp performance needs to be reduced by a minimum value of 75%. A study comparing metal halide and high-pressure sodium lamps showed that at equal photopic light levels, a street scene illuminated at night by a metal halide lighting system was reliably seen as brighter and safer than the same scene illuminate d by a high pressure sodium system. New street lighting technologies, such as induction or LED lights, emit a white light that provides high levels of scotopic lumens allowing street lights with lower wattages and lower photopic lumens to replace existing street lights . Formal specifications around Photopic/Scotopic adjustments for different types of light sources enables municipalities and street departments to test, implement and benefit from this new technologies.

  • Chapter 1: the Benefits of Converting to LED Street Lights in the Mid-‐Huds
    Chapter 1: The Benefits of Converting to LED Street Lights in the Mid-Hudson Region “Energy-saving improvements like LED lights are a common-sense way to cut costs and protect the environment at the same time.” –Mayor Mike Spano, City of Yonkers. The City completed an LED street light conversion in 2014, providing a gross savings of $1.8 million in the first year and cutting carbon emissions by nearly 3,000 metric tons annually.2 The light-emitting diode, or LED, is one of the most efficient lighting technologies on the market today, and is rapidly replacing other lighting technologies in many applications across residential, commercial, and public sectors. According to the U.S. Department of Energy, widespread use of LED lighting would have an enormous impact on energy consumption in the United States, potentially reducing energy use in 2027 by 348 terawatt hours,3 or the equivalent electrical output of 44 large power plants, and saving more than $30 billion.4 In the Mid-Hudson Region, the focus of this report, the potential energy savings from conversions is nearly 34 million kwh per year, with an annual energy cost savings of more than $2.1 million and annual carbon dioxide emissions reductions of nearly 18,000 metric tons. “The cost of street lighting services can be one of the more significant items in a municipal budget.” –Office of the State Comptroller, January 2008.5 Street lighting often accounts for a substantial share of municipal energy costs. For larger towns and cities in the Mid-Hudson region, street light bills can range from over $1 million dollars to close to $3 million dollars a year.6 In the small city of Kingston (pop.

  • Led Street Light Conversion Fact Sheet
    LED STREET LIGHT CONVERSION FACT SHEET PROJECT OVERVIEW Starting this July the City of Bend is converting over 2,000 existing public street lights to 3,000 Kelvin energy efficient, light-emitting diode (LED) fixtures to reduce the City’s energy costs, maintenance costs and greenhouse gas emissions. The project is one of several Strategic Energy Management projects happening in 2019-2021 to help achieve the City Council Climate Action Goals. The project replaces existing High Pressure Sodium street light fixtures on public streets with new LED fixtures. The project does not add new or remove old street light poles, it is just updating the existing fixtures. Work is being coordinated through Ameresco, the City’s Energy Management contractor, and the fixtures will be installed by their subcontractors NW Edison and Christensen Electric. PROJECT SCHEDULE The LED conversion project is scheduled from July to December 2019. Work activity will take place during weekdays and may include weekends. Work hours will generally be 7 a.m. to 7 p.m., targeting evening hours for arterial and collector streets. Multiple crews will be working to complete an estimated 30 – 40 fixture conversions per day, taking 20 to 30 minutes per light. Work will be performed in a moving operation that may require temporary traffic lane restrictions. While crews are working, the sidewalk, bike lane, or curbside parking spaces located adjacent to the work site will be temporarily restricted and in limited cases lane closures may occur. The crews do not typically need to turn off the power to perform the work. COST SAVINGS Installation of LED fixtures reduce street light energy consumption measured in watts by more than 50 percent since it takes less energy to provide a similar amount of brightness (or lumens).

  • Techno-Economic and Environmental Feasibility Study of Using Solar Led Streetlight in Nigeria: a Case in the City of Ilorin Kwara State
    TECHNO-ECONOMIC AND ENVIRONMENTAL FEASIBILITY STUDY OF USING SOLAR LED STREETLIGHT IN NIGERIA: A CASE IN THE CITY OF ILORIN KWARA STATE A. S. OLADEJI B. F. SULE O. S. BALOGUN TECHNICAL REPORT NO. 12 ISBN: 978-978-57350-3-1 NATIONAL CENTRE FOR HYDROPOWER RESEARCH AND DEVELOPMENT ENERGY COMMISSION OF NIGERIA UNIVERSITY OF ILORIN, ILORIN, NIGERIA DECEMBER, 2015 i Abstract This work presents techno-economic feasibility study of using solar energy and LED lights for street lightning in Nigeria using the City of Ilorin as a case study. The purpose of adopting solar energy is to relief the grid from huge energy consumption and to reduce the effects of climate change and global warming on the environment. The recommended LED lamps powered with solar energy can produce brighter lighting than the 250 watt high pressure sodium lamp bulb which is currently in use in the case study area and other parts of the country. Although, the initial investment cost of implementing the recommended LED solar street light is higher than the conventional street lights, the end result in the long run is quiet impressive in term of low maintenance cost, emission and reliability. The study on 400 lamps of 250W each showed that after 25 years of use, LED solar street lights additionally saves USD 293, 674 in addition to other saving: national electric grid energy. Moreover, it protects the environment by preventing 9855000푘푔퐶푂2 to be produced by the traditional electric street lights over a period of twenty five years. Keywords: Life Cycle Cost, Cost of Energy, LED, Insolation, Street lighting ii Acknowledgements The authors wish to thank National Centre for Hydropower Research and Development, University of Ilorin for supporting this research work financially.
