New London — The city and Eversource will host a free light bulb swap for residents from 9 a.m. to 3 p.m. Oct. 22 at the Senior Center, 120 Broad St., as part of the 2016 ENERGY STAR Change the World Tour.

City residents, with identification, may bring up to five incandescent light bulbs in any condition and exchange them for new, energy-efficient ENERGY STAR LED bulbs, free of charge while supplies last. Additional LEDs and lighting products will be available for purchase at a discounted rate.

“The LED giveaway is a great opportunity for New London residents to start saving money and energy at home,” Enoch Lenge, Eversource’s Energy Efficiency spokesman, said in a news release. “As part of the Change the World Tour, for each additional LED bulb purchased, another LED bulb will be donated to Habitat for Humanity.”

Energy experts from Eversource will be at the light bulb swap to answer questions and provide people with information on how they can save money and energy at home, including information on the popular in-home energy checkup, Home Energy Solutions.

In 2013, New London joined Clean Energy Communities, the nationally recognized Energize Connecticut program to help cities and towns save energy and increase the installation of renewable energy. Eversource is working with the city to help it reach its energy goals and reduce municipal building energy consumption by 20 percent by 2018.

Through Clean Energy Communities, New London residents that participate in Energize Connecticut programs — such as Home Energy Solutions — help the city earn points toward a grant. These “Bright Idea Grants” fund community-selected energy saving projects such as the upcoming light bulb swap, or the installation of new LED lighting at City Hall or a school.
