Although LEDs and solid-state lighting (SSL) have made great strides in the lighting marketplace over the past several years, reliable testing of SSL products and data documentation have not kept up. It has taken the lighting industry some time to understand how to develop a set of metrics to properly represent the nuances of this light source in architectural lighting applications.
The U.S. Department of Energy will host a 90-minute live webcast Thursday, October 11, 2007, at 10:00 a.m. Pacific Time/1:00 p.m. Eastern Time, called "LED Essentials: Technology, Applications, Advantages, Disadvantages".
