2014 Nobel Prize in Physics winner Professor Amano Hiroshi, recently stated LED lamps will be a mainstream consumer light source by 2016, but challenges remain.
Primarily, he points out, costs must come down further, starting with production costs, which should come down five times by 2020. For this to occur, demand must increase globally and new technology such as 3D nanowire LEDs exploited.
Amano discusses these issues and new LED applications in this article at the BizLED website.
