LED Streetlight Conversion FAQs

Why is Knoxville making the switch to LED?

The City of Knoxville spends approximately $4 million each year to cover the energy, operations, and maintenance costs associated with the city's approximately 29,500+ high pressure sodium (HPS) street lights. By converting these HPS lights to modern light emitting diode (LED) technology, the City anticipates achieving significant savings as a result of reduced energy consumption and reduced maintenance costs. Other benefits include:

• Improved light quality, including a reduction in light pollution and improved safety;
• Greater reliability, and fewer outages, sustained by a 10 year luminaire warranty;
• No disposal hazards;
• Greenhouse gas emissions savings, helping the City achieve its goal of reducing municipal greenhouse gas emissions 20% by 2020.

When will the project begin?

Phase 1 for the project will begin in 2017, and will include an extensive design phase that includes test/demo installations of new lights for evaluation by the City and public stakeholders.  Additionally, project staff can be available to discuss the project and LED lighting plans with neighborhoods and other community groups. 

Once the design phase is complete, Siemens expects to begin installation of new lights across the city in mid-2018. All work is expected to be complete by June 30, 2019. 

What's happening now?

Construction is slated to begin in August 2018.  Below is a progress map that will update as LED fixtures are installed.  Click on the point to get more information about that specific location.  If you have questions or comments, please email us at
