In 2011, CLASP launched a study to collect field data on background lighting levels during television viewing in homes in oder to support efforts by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) to revised the television test procedure for ENERGY STAR.

Since CLASP published the study “Analysis of Background Lighting Levels During Television Viewing,” several new issues have arisen, including the need for specific recommendations on luminance test points. As a result, CLASP has conducted additional analysis of the data collected to provide further technical support to EPA and DOE during the finalization of the revised test procedure.
