By appreciating the darkness when you design the light, you create much more interesting environments that truly enhance our lives.
Imagination is an instrument of survival.
We have to rethink the way we light our cities. We have to think again about light as a default solution. Why are all these motorways permanently lit? Is it really needed? Can we maybe be much more selective and create better environments that also benefit from darkness? Can we be more gentle with light?
There is actually a physical connection between light and our health and wellbeing.
By modulating the amount of blue in our environment, we can help people to relax, or to be alert; to fall asleep, or to stay awake.
