Homeowner finds switch of lighting saves money

When Dave Lippert swapped the light bulbs in his house for energy-saving LEDs, he figured they'd pay for themselves in a little less than three years. Turns out the break-even point came faster than he anticipated, leaving Lippert with even more money in his pocket. It's a good case study for homeowners anywhere who are pondering the financial return on switching to LEDs. Lippert, a retiree from the electric utility industry, started the project in 2012 as an experiment. He was confident the switch would cut his electric bill substantially, and he wanted hard evidence to win over skeptical friends and family members.
