Motorists may notice a different look to some streetlights, and possibly varying hues and brightness levels of some City of Yuma streetlights during the next several months as the City tests several versions of bulbs.
Several streetlights along 12th Street between Pacific Avenue and Castle Dome Avenue, just north of the Yuma Palms area, have been installed with light-emitting diode (LED) lights, with several more installations expected soon. Their performance will be observed over the next three months.
“This test is to make comparisons between different LED manufacturers and the current high-pressure sodium lighting,” noted City of Yuma Public Works Manager Pete Montalvo. “The goal is to complete the analysis and recommend a model for future LED installations around the city.”
LED lights carry several advantages over high-pressure sodium lighting. LEDs have two to four times the lifespan of sodium. They return to full luminance instantly in the event of a power failure, unlike bulbs that require heating time upon restart. They are additionally believed to be less attractive to nocturnal insects. And LEDs tend not to burn out; instead, their brightness fades over time.
Energy efficiency is one factor that has varied in case studies of LED streetlight usage worldwide, and is something the City will be observing during the test period, particularly over the hot summer months.
