The DOE GATEWAY program was launched in 2006 to conduct field studies of high-performance SSL products, collecting empirical data and documenting performance in field installations. Real-world installations often reveal product limitations and application issues that are not apparent from laboratory testing.
DOE shares the results of completed GATEWAY evaluations, publishing detailed reports and briefs on completed projects. GATEWAY typically documents pre- and post-installation light levels, color characteristics, energy use, and other performance attributes, and addresses application and maintenance of SSL products.
