Cambridge to replace 5,000 streetlights with energy-efficient LEDs

On Monday, the Cambridge Department of Public Works began replacing cobra head light fixtures with Light-Emitting Diodes – or LED – to help save energy. The replacement of the roughly 4,800 cobra head lights will be completed sometime in August. City Electrician Steve Lenkauskas said the work will not interfere with residential traffic or parking, as the trucks used for replacement will follow the street sweeping schedule. He anticipates, between all the trucks, the city will replace roughly 100 lights per day over the next three months.
