9,000 Manchester streetlights to get LED upgrade
City officials will begin the bidding process for a contractor to fit about 9,000 streetlights with efficient LED (light-emitting diode) fixtures, after they presented a final agreement with Public Service of New Hampshire to the Board of Mayor and Aldermen this week.
Buying and installing the lights, however, will entail hefty up-front costs in the range of $2 million to $3 million. The exact amount will depend on the bids submitted to the city’s request for proposals, which is expected to be issued in the next couple of weeks.
So far, aldermen have expressed support for the conversion to LEDs, citing both greater efficiency and improvement in light quality over the orange-ish light cast by the high-pressure sodium lights most commonly in use throughout the city.
Deputy Public Works Director Tim Clougherty said the LEDs have several benefits. “There’s the greater efficiency, but it’s also a more directed light,” he said. “We’ll be directing more light at the street and decreasing light pollution.”
Clougherty estimated that it would take 1 to 1.5 years for all of the city’s streetlights to be replaced with LEDs.
