Power LED technology will likely become the technology of choice for solid state lighting (SSL) applications. The technology is progressing rapidly, but there are still areas that must be improved before SSL substantially replaces conventional lighting technology. These include cost, efficiency, and uniformity of the emission spectrum. Associated technologies especially electronic drivers also need to be improved. It is now clear that SSL will dominate virtually all lighting applications, and the transition is in progress, but the timing for substantial market penetration is less certain.
