Salt Lake City, Utah, to install 1,370 LED streetlights from Lighting Science Group

The city of Salt Lake City, Utah, is preparing to implement its first, large scale LED streetlight installation project. The city is using $850,000 of funds from an Energy Efficiency and Conservation Block Grant (EECBG) award from the U.S. Department of Energy to purchase 1,370 LED streetlight fixtures. Following a competitive bid process, the city chose the PROLIFIC LED fixtures from Lighting Science Group, a manufacturer based in Florida.
“We tested and evaluated seven separate LED streetlight fixtures. These fixtures were ordered, installed and tested by our crews, and we took a series of measurements including lighting levels. It was critical for us to see the fixtures installed and running in the field,” said Mike Barry, transportation engineer for the city of Salt Lake City. Barry had also considered induction technology but found that LED technology performed better in roadway lighting applications.
The installation involves 1,370 LED streetlight fixtures, which will be installed along the city’s arterial roadways. The new 146 watt LED fixtures will replace existing 250 watt high pressure sodium (HPS) cobra head streetlights. Barry anticipates a reduction in energy consumption of approximately fifty percent with the new fixtures, which will result in an annual rebate of about $70,000 from the local power company, Rocky Mountain Power.
Salt Lake City owns and maintains about fifteen thousand streetlights. According to Barry, the city intends to continue replacing the remaining HPS fixtures with LED streetlight fixtures as additional funding becomes available.
