Four-month test shows up to 60% energy savings.

PolyBrite Intl. Inc. (Naperville, IL), the creator of Borealis LED lighting systems, has announced the installation of Borealis LED streetlights has saved Naperville, IL up to 60% in energy usage for each of the four months of usage. The city has been monitoring the LED streetlights since June, and they will continue to do so until January 2010.
The LED streetlights are installed along the south side of Diehl Rd., between Country Club Blvd. and Fairway Dr. The city’s Dept. of Public Works is monitoring seven, 120W Borealis LED streetlights with a similar number of 350W, 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 the 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.
Carl Scianna, president and CEO of PolyBrite, said, “With a life expectancy of 50,000 hours, Borealis LED streetlights will last five times longer than the HPS lights the city is currently using and they produce a safer, cleaner light that improve the overall appearance, night time safety and night time visibility. Having no arc tube or filament, Borealis LED streetlights are a true, solid-state lighting product!”
