Cree Inc., an LED manufacturer located in Durham, N.C., has been selected to provide energy-efficient lighting for Walmart renovations and new construction. Walmart plans to install LRP-38 lightbulbs in 650 stores during the first year, replacing ceramic metal halide in the produce and electronics departments. According to Cree, the PAR38-style lamp was selected because of its energy efficiency, long lifetime, controlled beam and high color rendition. Designed to last 50,000 hours, the LRP-38 consumes 82 percent less energy than the 70-W ceramic metal halide bulbs it replaces and can last more than five years in a 24/7 operating environment.
