“The finer things in life lights are rigorous test reports” The last post on solid-state lighting (SSLs, which are also commonly known as LEDs, or light-emitting diodes) explained one of the consequences of the rapid pace of technological improvement: the vastly different quality levels of new products at any given time. The post provided guidelines and shortcuts that consumers can use to help choose the right product from an enormous selection. To help consumers further narrow... [More]

“How to check the fine print without a microscope… or an engineering degree” In a previous post, we highlighted a new resource for municipalities looking to find out how solid-state lighting (SSL, a.k.a. LED) can help reduce energy costs while helping to meet efficiency goals.  The SSL Playbook  calls attention to the variability in LED product quality and performance. In some cases, such as shown in the figure below, the tested “efficacy” of LED pro... [More]

 “LED, follow, or is something in the way?” Energy efficiency is such an amazingly broad and dynamic field that even experts struggle to keep up with it. Nowhere is this more evident than when a primary change agent shares the majority of its technological DNA with the semi-conductor and power-electronics industry, as in the case of Solid-State Lighting (SSL). Colloquially known as LED lighting, SSL is disrupting conventional understanding about interior/exterior space a... [More]

Sometimes getting a bad grade on an exam is precisely what a student needs to evaluate old habits and make necessary changes.  For several cities in the United States, the results of the first National Traffic Signal Report Card (in which the average U.S. city received a grade of D-) inspired changes in the way they managed their traffic signals in order to reduce traffic delay for citizens and save operating costs for the cities.  The second version of the report card, which was ...
