The U.S. Department of Energy (DOE) has published the findings of a new study utilizing a highly accelerated life-test method (called the “hammer test”) intended to produce failures in SSL luminaires in a reasonable test period, with the goal of providing insight into potential failure modes. EntitledHammer Testing Findings for Solid-State Lighting Luminaires, the report was prepared by RTI International for DOE’s LED Systems Reliability Consortium.
