Ambience is a feeling we intuitively sense in every space we inhabit. It can empower, invigorate, agitate, calm or generate happiness whenever we enter a room. It goes beyond the 'look' of a room into the sound, smells etc. that trigger a reaction. Ambience is a subconscious reaction especially when done right.
Coelux has created an ingenious way to add the ambience that is light without real light. Brilliant.
