Abstract:Street lighting improvements provide an opportunity for governments to save money and to reduce their
environmental footprint. New energy-efficient technologies are being perfected that are more efficient than
standard high-pressure sodium streetlights. Light-emitting diode (LED) and induction are two types that hold
promise of saving money while using less energy to reach light standards. Many manufacturers have developed
energy-efficient lighting products with a variety of performance claims. There has been limited in-field, head-tohead
testing of these products, particularly in cold weather climates, to help governments choose the most suitable
product.
This research project had two aims: (1) compare lighting performance among induction, LED, and standard highpressure
sodium streetlights, and (2) compare lighting performance among six LED brands/manufacturers and three
induction brands/manufactures to evaluate consistency by vendor. This research evaluates the LED and induction
streetlights on several measures: (1) energy consumption, (2) operating costs, (3) maintenance calls, (4) light levels
and quality, and (5) public reaction/acceptance.
