New Research on LED Street Lighting Evaluates Claims

摘要

At the electric power research institute (epri), researchers recently released findings from a study of light-emitting diode (LED) street lighting technology. What they found should be of interest to electrical contractors. LED proponents typically make certain claims. For example, in contrast to traditional streetlights, which emit yellow light, LED streetlights are white. Traditional lamps need replacement in three to four years, whereas LED manufacturers claim a 20-year life span. Traditional luminaires are known to blast light onto sidewalks and lawns, into the air, and sideways as glare, but proponents contend LED luminaires focus light where it is needed. The EPRI demonstration project gathered data to evaluate these claims for the entire lighting industry.
