LED street lights to save Boulder $3,842 a year

The City of Boulder will soon start saving about $3800 a year on the cost of energy to light its streets, representatives from NorthWestern Energy recently told city officials.

The savings will follow the replacement of about 90 high-pressure sodium street lamps with more-efficient LED versions.

The swap is expected to take place over three days later this month, NorthWestern Energy engineer Steve Schmitt told the City Council Sept. 16.
