White LED showed up around 10 years ago when LED came to markets in larger quantities. In this branch from the start there was a tendency to achieve qualities of light equal to traditional sources and then replace them completely (the guess is that in 5 years range this could happen). Current technology abilities of producers brought a new dimension of light control and regulation because it is possible to control temperature and power of the LED light on line. So called power LED is a novelty in the offered product range, thanks to optical adjustments their output of light matches halogen spotlights, while the energy use is much lower.
