Back in 2008, the Department of Energy (DOE) launched the Bright Tomorrow Lighting Prize (L Prize) competition, as instructed by the Energy Independence and Security Act of 2007. The L Prize challenged the lighting industry to develop an efficient LED to replace the common 60 watt incandescent bulb. Any entries received were put through rigorous short-term and long-term performance testing. The winning bulb was required to produce more than 900 lumens and also have a 25,000 hour life. In addition, it must also have a Color Rendering Index (CRI) higher than 90 and a Correlated Color Temperature (CCT) between 2700K and 3000K-all while using less than 10 watts of electricity!

If you’ve watched the news recently, you may have heard the controversy surrounding China’s export restrictions on a number of resources, including rare earth elements. What may not be fully clear is how this affects you as a consumer of electronics, and lighting products in particular. We’ve put this together as a quick overview to let you know what’s happening, and what to expect going forward.
First, let’s look at what rare earth elements are, and what they’re used for: Rare earth element is the common name for a set of 17 chemical elements. They are critical in the production and operation of a wide range of consumer electronics, and are also used in the phosphors that create light in a number of different light bulb types, including fluorescent, LED, and mercury vapor.
