The U.S. Department of Energy's (DOE) Solid-State Lighting Program has released a new report that estimates the installed stock, energy use, and lumen production of all general-illumination lighting products operating in the U.S. in 2015. The third such report issued by DOE since 2002, it provides the baseline that helps DOE plan its R&D program, and is used by both governmental and nongovernmental organizations for planning and evaluating lighting opportunities as well as additional research efforts.

The U.S. Department of Energy has just completed the first study in a series on connected lighting system (CLS) interoperability. The main goal of the series is to discern and document the current state of CLS interoperability at this early stage, with its landscape of multiple vendors, technologies, and business models. 

The U.S. Department of Energy has released a new Snapshot report on LED outdoor area lighting. Based on DOE's LED Lighting Facts®database, the report focuses on outdoor area/roadway luminaires (including street lighting and wall packs), parking garage luminaires, and canopy luminaires (e.g., those used for gas station fuel pump areas). Retrofit kits and dedicated luminaires in these categories are not considered separately, as only in the area/roadway category did retrofit kits make up a notable percentage (8%) of the products listed in the category.

The U.S. Department of Energy's GATEWAY program has released a new report on a trial installation of tunable-white LED lighting systems in three classrooms in the Carrollton-Farmers Branch Independent School District in Carrollton, TX, which provides valuable insights into the use of this technology in a real-world setting.
