Assessment of Solid-State Lighting, Phase Two

"The penetration of solid-state lighting (SSL) has increased dramatically since the publication of the National Research Council (NRC) report Assessment of Advanced Solid-State Lighting in 2013. The Committee on Assessment of Solid-State Lighting, Phase 2 has been surprised by this rapid adoption and the accompanying diversity of applications of SSL, which has been driven largely by the dramatic decline in the retail price of lamps and luminaires, and recognition of the unique qualities of the light emitting diode (LED) light source. Improvements in lamp performance, the introduction of innovative applications, improved compatibility of lamps with controls, and the integration of LED lamps in systems have all contributed to this rapid acceptance. Examples of exploiting the special characteristics of SSL are the introduction to steerable headlamps in cars, the use of spectral control to prevent lighting-induced damage to artwork, and more efficient and controllable street lighting. Accompanying this growth in the SSL market has been the rapid decline of compact fluorescent lamps (CFLs) from retail shelves"--Preface, page vii.
