Meijer has announced a new sustainability initiative.
Walker-based Meijer plans to transition the interior lighting of all its stores to LED by 2021.
The company expects the change will reduce its lighting electrical use by as much as 50 percent annually.
The LEDs being used are supplied by GE, Cooper and Phillips.
Meijer first implemented an all-LED store in Beavercreek, Ohio in 2013.
"Our Beavercreek location served as a great test that led us down the path to planning a full-chain transition across our six-state footprint," said Rick Keyes, president and CEO, Meijer.
"The lighting quality made possible by LEDs enhances the shopping experience for our customers and the work environment for team members, while significantly decreasing energy usage."
The four-year project launched in June with the company's 100-plus stores in Michigan.
The retailer will "phase in" other locations state by state within its six-state footprint, so the stores can remain open during the installation process.
The LED transition follows other sustainability initiatives by Meijer, including constructing energy-efficient buildings, using a low-emissions truck fleet and offering a wide selection of local and sustainable products.
