The DOE GATEWAY program was launched in 2006 to conduct field evaluations 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. In some cases, GATEWAY returns to projects after months or years of operation to take additional site measurements or to remove luminaires for testing at accredited laboratories. The results provide valuable information on long-term performance, including lumen maintenance, dirt depreciation, color shift, and durability.
- Indoor projects include classroom, healthcare, and office installations.
- Outdoor projects include street, roadway, parking, and pathway lighting
- OLED projects offer insight into the performance of today’s OLED products.
- Special reports take a closer look at specific topics of interest, such as dimming, controls, and color maintenance.
