Last year, the Arkema chemical manufacturing site in Axis, Ala., replaced a significant number of high pressure sodium, metal halide and fluorescent lights with more energy efficient LED light fixtures, resulting in an immediate improvement in light quality to create a safer working environment for employees. Not only are LED lights more efficient, but they require less frequent change out of bulbs, many of which are located in areas with difficult access. Approximately 190 light fixtures were changed over to LED fixtures and bulbs. Expected energy savings is 151 megawatt hours per year, and $15,000 per year. In addition, the reduced energy usage results in 113 tons of reduced CO2 emissions to the atmosphere.
