Solid-state LED street lights present significant benefits to street light operators as well as drivers and pedestrians. Questions remain, however, about their performance in high temperature conditions. This paper explores the performance of LED street light in one of the hottest regions in the world. Two LED street lights were installed in an actual street in the city of Al Ain, United Arab Emirates. The street was closed to the traffic and illuminance measurements were taken daily every 10 minutes throughout the summer of 2010. Temperature and relative humidity values were also taken inside the two light fixtures as well as outside the fixtures. The summer of 2010 had significantly high temperatures with one week in July reaching maximum ambient temperatures of 53°C. This paper shows the Lux levels as well as the temperature and relative humidity data acquired in the field. Results show fairly stable light levels throughout the summer. The Lux levels did not change by more than 10% throughout the summer.
