LED Street Lights

Over the past several years we have been working on our 20-40-15 initiative, which is aimed at improving energy efficiency in City facilities by 20 percent, improving the fuel efficiency of the City’s vehicle fleet by 40 percent and achieving these goals by the year 2015.

We are getting close to achieving our goal through current city projects such as:

  • Advanced energy recovery strategies for our Community Center ice rink cooling system, including recovery of waste heat from compressors, variable speed drives for pumps and fans;
  • The installation of energy-saving ceilings in the these same ice rinks; and
  • The addition of electric vehicles to the City’s fleet, as well as an electric vehicle charging station at City Center.

But we are always looking at more ways to be energy efficient and “green”- even if it is not directly related to our city buildings or our fleet.  Our newest project is the installation of light emitting diode (LED) street lights.   

LED Streetlight

We recently retrofitted several 250-watt high pressure sodium street lights with more energy efficient 100-watt LED street lights.  The new LEDs were installed as part of a pilot project on Viking Drive between Flying Cloud Drive and Prairie Center Drive.  The city contracted with Lighting House USA of Plymouth, Minnesota to manufacture the LEDs- and our own city crews installed them.  

While LED street lights are not new to the market, we are one of the few cities that have installed them.  Additionally, the manner in which we installed the lights is very unique.  Working with our vendor we were able to reuse the existing street light housing units and just simply replace the internal system with LED panels.  This reduced the amount of new material needed to retrofit the lights, resulting in a significant cost savings to the city and less material being land filled.  

The total cost of the project was $3,108.00 for seven lights – much less than the cost of all new LED lights and fixtures.    

The benefits of LED lights include:

  • Reduced maintenance costs because of their longer life cycle as compared to traditional lights;
  • A 60% energy usage reduction;
  • Less waste because the existing housing units were reused; and
  • A more natural light color display 

As an added benefit, this was all accomplished while using a Minnesota based LED manufacturing company.

    That comes out to nearly $450 per light. I have to wonder how long it takes to recover that in energy savings.
    Great that you could use existing housing units and a Minn. company for the work. (I wouldn’t consider “more natural light color” as anything worth the cost of conversion.)
