Las Vegas changed 42,000 street lights

As a part of the city of lights efforts to reduce its carbon emission, 42,000 LED street lights have been installed all over the city. The replacement of traditional street lights to LED street lights will allow the city to save $2 million per year.

This street light project cost $20.8 million to the city of Las Vegas. The city installed 6600 LED street lights in some spots to test the efficiency of this lighting solution to assess the performance of this lighting solution before expending it across the town.

Since 2006, discussion started about the replacement of Las Vegas' street lights. Many doubts were raised about the success of the street lighting project. The city's officials thought the technology was not good enough to meet their high expectations in terms of quality and performance. Few years later, after analyzing the street lighting market, Las Vegas' officials launched a call for bid to assess the lighting industry's ability to reach the city's requirements on cost-efficiency, energy saving, performances and lifespan.

They analyzed several propositions and selected LED street lights for their high performances. When HID (High Intensity Discharged) light tends to distribute lights on several direction, LED light can be focused on a pathway or roadway for example. Moreover, this street light provide a bright and clear white glow, more natural, compared to the yellow light the city used to have. LED street lights need less energy to operate and, with a lifespan of about 70,000 hours against 20,000 for their previous street lighting solution, less maintenance. Las Vegas expect to cut its electricity bill by 50% thanks to LED street lights.
