2015 International Year of Light

International Year of Light logoThe UNESCO (United Nations Educational, Cultural & Scientific Organisation) declared 2015 the International Year of Light and Light Based Technologies.

A series of events will take place throughout the year in all corners of the globe to promote improved understanding of the central role of light in the modern world.

While Australia starts every New Year with a spectacular light show at its annual New Year's Eve fireworks display at Sydney Harbour, it was Paris that hosted the first official Year of Light event at the two day opening ceremony at UNESCO headquarters on 19-20 January.
