A Systematic Approach for Evaluating LED Street Light Fixtures

This article describes how light emitting diode (LED) street lights are gaining a lot of popularity throughout the United States (US) and the world. Numerous companies have offered LED street lights for years and have had reasonable success in various lighting projects. However, due to the high cost of LED street lights and the marginal energy savings that they currently provide, LED street lights must provide other benefits including reduced maintenance, better light color rendering, better light uniformity, lower light factors and other areas that help improve performance of the bottom line. This article describes how the City of St. Cloud, Minnesota had the opportunity to fund several projects including the installation of LED street lighting. In order to get the best light fixture for the City, St. Cloud’s Traffic Services developed a series of tests and comparison methods that provide an objective method for comparing decorative LED fixtures. The test deck and evaluation process provided the City with invaluable information on the quality and lighting capabilities of the various LED light fixtures that were tested. It also provided the city with much more objective data and comparisons that are difficult to get from the manufacturers.
