Project Fixtures & Controls

The Metropolitan Government of Nashville and Davidson County is upgrading more than 55,000 public streetlights as part of a citywide LED conversion. This modernization replaces older high-pressure sodium, mercury vapor, and metal halide fixtures with long-lasting, energy-efficient LED technology. The new fixtures improve visibility, reduce energy and maintenance costs, and support Nashville’s Vision Zero and DarkSky-aligned goals.

Streetlights across Metro fall into several fixture families – such as cobraheads, high masts, teardrops, and decorative post-tops – each selected based on roadway type, lighting needs, and location. NES and NDOT have jointly approved updated LED fixture options for the project, ensuring consistency with Nashville’s Lighting Guidelines and performance standards.

In addition to fixture upgrades, the project includes a transition to a smart, networked control system. New control nodes installed on each LED fixture allow for remote monitoring, outage detection, dimming, and integration with future smart-city initiatives.
