DP&L is hosting a light bulb exchange Saturday at the Huber Heights Branch of the Dayton Metro Library, 6160 Chambersburg Road, from 10:30 a.m. to 12:30 p.m.
The public can bring inefficient incandescent bulbs to exchange for new ENERGY STAR certified LED bulbs, up to five per person, while supplies last.
This event is to encourage the use of LED bulbs, which use up to 90 percent less energy and can last 25 times longer.
