With almost 500,000 street lamps in use in Minnesota, replacing older less-efficient high-intensity discharge (HID) or metal halide technologies with more efficient options, such as light-emitting diode (LED) and induction lamps, represents a real opportunity for reducing costs and energy use. In 2011, a CARD grant was awarded to Energy Management Solutions to examine the major design and specification concerns of roadway lighting and to quantify costs and benefits of upgrading to more efficient street lighting.
Results of this study will be given in a free webinar. The presentation will go through a 10-step “how-to” manual for the appropriate selection of LED roadway luminaries that was developed as part of this study. It will also review a method to analyze the economics of replacing HID roadway lighting systems with comparable LED technologies, and considerations for design of utility conservation improvement programs.
