Nobel Prize in Physics awarded to three Japanese scientists.
While I will not get into an argument over the merits of the blue LED vs red or any other colour,
here are some points why the creation of the blue LED and hence white lighting is revolutionary according to Professor Emeritus Christopher Hall, Centre for Materials Science and Engineering, University of Edinbugh:

1. Brings lighting to many communities in the world that have no electricity grid.
2. Low energy consumption
3. Blue LED paves the way for UV and ultra-UV LED which can be used for such things as water purification.
4. White LED lighting can be used for Li-Fi transmission superimposed on top of regular room illumination.
This brings an alternative to short range bluetooth transmission.
And this brings another closer meaning to the word "bluetooth" which is originally named after King Harald Bluetooth of Denmark.
