    News below: Every Wallmart parking lot in the world to be lit with GE LEDs.

    Just the fasts.

    Walmart's first full-scale test of LED parking lot lights was at a Neighborhood Market in Rogers, Ark., in 2008. We found the same benefits - big energy and maintenance savings - and some new ones. LEDs are directional, meaning we can better focus the light on our parking lots and limit nighttime glare. Gradually, we began rolling out LED parking lot lights in our international markets that have the highest energy costs. We converted 22 sites in Puerto Rico, saving more than 8 million kilowatt hours of energy in 2009, and we are in the process of converting 350 stores in Central America. Our operations in Mexico also began implementing this technology last year and just in the last few weeks our U.S. program has specified LED lighting as a solution for new store parking lots going forward.

    This program also helps export America's "green" technology. Nearly all the LED parking lot light fixtures we use are manufactured by General Electric in its Hendersonville, N.C., facility and sent to our operations outside the U.S.

      Lighting the Future: Walmart Converting Hundreds of Stores' Lot Lighting to LEDs

      The following is a guest post from Charles Zimmerman, vice president of international design and construction at Walmart.

      Today it takes a lot of coal, natural gas, wind, solar and other energy sources to power lights around the world. The good news is lighting is getting more efficient and consuming less energy; the bad news is more lighting is being added every day. The move from incandescent light bulbs to compact florescent light bulbs is helping reduce energy use and greenhouse gas emissions, and LED lights will accelerate those savings in the not-too-distant future.

      At Walmart, that future is now. Because electricity is the number two operating expense in almost every one of our stores and clubs around the world, we have been focused for decades on efficiency and reducing energy use, particularly from lighting. In 2005 we discovered a game changer when we installed our first LED freezer case lights at a store in McKinney, Texas. We found that these LEDs use approximately 70 percent less energy, create much less heat (important in a freezer case) and last about as long as the cases do - saving money on both energy and maintenance costs. LED freezer case lighting is now the standard in all new Walmart facilities around the globe, and this technology is quickly becoming the norm in the industry. Whether you're in a supermarket in Australia or a hypermarket in South Africa, you're likely to find LED lights in the freezer cases.
