New Energy Conservation Standards for Metal Halide Lamp Fixtures, External Power Supplies
The Department of Energy has issued a final rule imposing more-stringent energy conservation standards for metal halide lamp fixtures. These new and amended standards, which are the minimum allowable ballast efficiencies based on fixture location, ballast type and rated lamp wattage, will apply to all covered fixtures manufactured in or imported into the U.S. on or after April 11.
The DOE has also issued a final rule amending the energy conservation standards that currently apply to certain external power supplies and establishing new energy conservation standards for other external power supplies that are not currently required to meet such standards. These standards prescribe a minimum average energy efficiency during active mode (i.e., the item is plugged in and supplying power in response to a load demand from another connected device) and a maximum power consumption level during no-load mode (i.e., the item is plugged in but is not supplying any power in response to a demand load from another connected device). The standards will apply to all covered products manufactured in or imported into the U.S. beginning Feb. 10, 2016.
