  • Walmart Selects Cree LEDs
Nov 2009
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.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
