More Sioux Falls street lights will likely be swapped out for newer, brighter, more efficient lights next year.

The city of Sioux Falls in May launched an LED streetlight pilot project in six neighborhoods throughout town when it replaced 65 high-pressure sodium streetlights with energy-efficient light-emitting diode (LED) lights. The new streetlights, expected to last at least 100,000 hours, provide at least the same amount of light but use about half as much energy as the more common sodium bulbs.

“We expected to see anywhere between 30 to 50 percent energy reduction with the new LED lights,” Light and Power Superintendent Jerry Jongeling said. “Our most recent metrics show that we are able to run an LED streetlight for 11 cents per day, in comparison to the 33 cents per day we spend to power a standard 250-watt HPS light. This is a cost savings of more than 50 percent, even before adding in the maintenance expense savings.”
