Many people are not aware of how much light affects their lives and mood: light determines how we perceive moments and how we feel about them. People have always shared these strong feelings about light — we love the light of a sunset or a candle, and we even travel after the sun. Why don't lights also offer such an emotional lighting experience?

From this question the mission of GRAU was born: to activate people's feelings with light. Our goal is to give people a deep experience of light and to make them happier with our light.
