Lighting Up History: QC Lights Installs Gemstone Permanent Lighting at the Peoria County Courthouse
When one of Central Illinois’ most iconic landmarks needed a modern lighting solution, Peoria County turned to QC Lights, trusted experts in permanent outdoor lighting across the Midwest.
Now, the Peoria County Courthouse glows beautifully at night, blending historic architecture with smart, energy-efficient Gemstone Lighting technology.
Located at 324 Main Street in downtown Peoria, Illinois, the Peoria County Courthouse has long served as the heart of county government. The current building, completed in 1964 to replace earlier courthouses dating back to 1829, 1833, and 1873, continues that legacy as a central civic and government hub.
In 2025, county officials embarked on a comprehensive modernization project to enhance the courthouse plaza, improve public safety, and illuminate its architectural character after dark. QC Lights was honored to be selected as the lighting partner for this transformative upgrade.
The Peoria County Courthouse is more than a government building — it’s a historic landmark that bridges Peoria’s rich architectural past with a modern civic identity.
As part of an ongoing plaza renovation, QC Lights designed and installed Gemstone Permanent Lighting, enhancing both energy efficiency and nighttime visibility while preserving the structure’s clean, modern lines.
The new system provides year-round flexibility, allowing county officials to celebrate holidays and civic events with programmable lighting — from patriotic red, white, and blue to warm architectural white for daily use.
Community Impact & Sustainability
This upgrade goes beyond aesthetics. It’s a key step in Peoria County’s ongoing downtown revitalization project, which includes new lighting, fountain updates, pedestrian spaces, and landscaping.
With Gemstone LED technology, the courthouse can now:
Reduce energy usage compared to traditional floodlighting.
Lower maintenance costs with long-lasting LEDs.
Minimize light pollution through precision control.
Support community events with custom colors and animations.
Learn more about energy-efficient lighting benefits from the U.S. Department of Energy.
This installation symbolizes Peoria’s balance of progress and preservation, a civic beacon for generations to come.
