In September 2011, MnDOT installed 10 LED and 10 HPS luminaires along a trunk highway. MnDOT employed data-logging meters to gather hourly electrical operational characteristics relative to both types of light sources. A light meter was used to collect lamp color temperature data and identify changes in the specified color temperature as the LED luminaires aged. This document presents the collected data.
These appendices pertain to report 2016-17, Implementation of LED Roadway Lighting.
