Metal Halide Lamps: DOE Updates Efficiency Standards
The US Department of Energy has finalized new energy efficiency standards for metal halide lamp fixtures.
Metal halide lamp fixtures include the ballast, which starts and regulates the electrical current for these lighting systems. They are commonly used for parking lots and streets, flood lighting, athletic facilities, big-box stores and warehouses. On average, one metal halide lamp fixture consumes about 2,210 kilowatt hours of energy per year.
The new efficiency standards update the 2007 standards for metal halide lamp fixtures. These standards incorporate feedback from industry, consumer and environmental advocacy groups and other stakeholders and will go into effect three years after publication in the Federal Register.
In November, the DOE proposed new and amended energy conservation standards for certain commercial and industrial electric motors, including a number of different groups of electric motors that DOE has not previously regulated.
