A $1.477 million contract to convert all 2,538 streetlights in town to efficient LED fixtures won town council approval Tuesday, paving the way for work to begin next month on a project expected to pay for itself in less than 4 years. The project is part of an $8.77 million energy conservation plan the town approved this month with project contractor NORESCO. The plan calls for the town to own all the streetlights in town. The contract includes upkeep of the poles and fixtures. Tanko Streetlighting of San Francisco is the vendor for the job. 12/18 Hartford Courant.
