“In what city officials describe as the largest LED bulb giveaway in history, the environment department will distribute 20,000 lights via public libraries. At any library branch, city residents need only to flash their library card to obtain a four-pack of bulbs. Each one can last up to 22 years and uses about one-sixth of the energy of a conventional light bulb.
