OVERVIEW: The continuing evolution of solid-state lighting (SSL) has been driven by ever-present market factors such as improved energy efficiency, increased product life, reduction of maintenance costs, and lessening environmental impacts. These market drivers have generated a desire for energy-efficient SSL products, but before a full-scale industry transformation can take place, it is necessary to prove that the performance characteristics of commercial SSL products will meet or exceed those of traditional lighting technologies.

This Webcast will discuss performance standards developed for testing solid state lighting products, including IESNA LM-79-08: “Approved Method for Electrical and Photometric Measurements of Solid-State Lighting Products” and IESNA LM-80-08: “Approved Method for Measuring Lumen Maintenance of LED Light Sources.”

The speakers will describe the testing requirements of these standards and other performance testing options, explaining the types of measurement that are required and the relevant test methods. The Webcast will also look in detail at the test equipment options that companies should consider, identifying the key pieces of equipment that are necessary to make the measurements for each standard.

The Webcast will also discuss environmental performance testing e.g. exposing SSL products to stresses such as temperature, humidity, dust and shock, as well as junction temperature testing.
