During these dark winter months, spare a thought for artificial lights. From strings of lights adding holiday cheer to artificial sunlamps alleviating seasonal affective disorder, they brighten our days. And light's applications can go much further than that. The United Nations designated 2015 as the International Year of Light and Light-Based Technologies to raise awareness of how photonic technologies offer solutions to international challenges. Light technology is now an active area of research in energy, health and agriculture.
