Detroit's lighting authority starts replacing defective LED streetlights

The city's Public Lighting Authority has begun efforts to replace nearly one-third of its LED streetlights only a few years after they were installed because of defective equipment that's causing premature dimming and failures. The Detroit News first reported last month that the authority had filed a federal lawsuit against the manufacturer, Leotek Electronics USA, arguing the problems put the city's revitalization progress "in jeopardy" and a fix is expected to cost millions.
