PolyBrite International Announces Greener Results in Borealis LED Streetlight Testing

PolyBrite International announced today that the installation of Borealis LED streetlights has saved the City of Naperville up to 60% in energy usage for each of the four months of usage. The City of Naperville has been monitoring Borealis LED streetlights since June and they will continue to do so until January 2010. 

The Borealis LED streetlights are installed along the south side of Diehl Road, between Country Club Boulevard and Fairway Drive. The city’s Department of Public Works is monitoring seven 120 watt Borealis LED streetlights with a like number of 350 watt high pressure sodium (HPS) streetlights. One meter in the streetlight controller monitors the power consumption of the LED lighting, with a second meter monitoring the power consumption of the HPS lighting. To date, measured results from the study have tabulated Borealis LED streetlights have consumed 57.2% less energy than the HPS streetlights. The meter readings have also indicated that the Borealis LED streetlights monthly energy consumption was 382 while the HPS was 892. 

Each Borealis LED Streetlight will use 1,137 fewer kilowatt hours of electricity per year than the HPS. This reduction in electricity will reduce carbon dioxide emissions by 646 grams per year, nitrogen oxide emissions by 1,121 grams and sulfur dioxide emissions by 3,968 grams per year per streetlight. 

Residents have been asked by the city to give their opinion on PolyBrite’s Borealis LED street lighting by contacting the City of Naperville Public Works Department through January 2010. PolyBrite anticipates that continued savings projections will be achieved during this six-month demonstration.
