Work has begun to convert the city’s 7,205 streetlights to Smart technology Light Emitting Diode (LED) streetlight fixtures, which will reduce energy use, electricity costs and maintenance costs.
The impact will be as follows…
Energy costs reduced by 54%
Maintenance costs reduced by 80%
Reduced light pollution (the LED fixtures are “Dark Sky Compliant” as all light is directed downward)
Better light quality for pedestrians and vehicle traffic

It’s estimated that the conversion to Smart technology LED fixtures will reduce annual electricity costs by 54 percent or by $650,000, and reduce maintenance costs by 80 percent or by $187,000.
The City expects to save an estimated 3,618,570 kilowatt-hours of energy per year, a 70 percent reduction compared to the current energy consumption for City streetlights. The reduction is the equivalent of the typical energy use by 375 homes for an entire year. The annual electricity cost is expected to be reduced to $552,800 from the $1.2 million for the existing streetlights, a savings of $650,000.
The new LED lights will last up to four times longer than the previous High Pressure Sodium (HPS) streetlights which will be removed and recycled at qualified environmental disposal centers. Photo: Evan Holt
LEDs will also help the City reduce maintenance costs by a projected 80 percent because LEDs are a solid-state technology (no moving parts) and last up to four times longer than the City’s existing streetlights.
Maintenance costs will be reduced to an estimated $46,700 a year from the current annual cost of approximately $233,700 for the traditional streetlights, a savings of $187,000.
