The Light Up the World Foundation is a humanitarian organization based in Canada, which is dedicated to bringing safe, affordable, and efficient lighting to an estimated 2 billion people worldwide who do not have access to adequate lighting.

When the foundation gives someone adequate lighting for their home, people can have a time and place to begin a process of educating themselves beyond their farm work jobs which often last from sunup to sundown

According to Professor Nakamura, we have only just begun to explore the vast number of opportunities presented by applications using LEDs and lasers.

This is not just a source of light that makes enormous energy savings possible, it is also an innovation that can be used in the sterilisation of drinking water and for storing data in much more efficient ways." Millennium Prize Foundation News Release
