Implementation of LED Roadway LightingStatus: CompleteReport Date: 06/07/2016 Summary: This project monitored 10 LED roadway luminaires installed in St. Paul in 2011 to evaluate the consistency of the color of light and the impact of the LED luminaires' electrical properties on other devices. Nearly four years after installation, the color of light from the luminaires had degraded significantly, and other operational issues meant that only one luminaire remained fully functional throughout the test. However, the tested luminaires were among the first commercially available options, and the technology has improved substantially since then, so these results are not reflective of current LED offerings.
