Today's context is one of strong, steady growth in demand for lighting, and a new determination to stabilize, if not reduce, energy consumption and the environmental impact of lighting. As we have seen, the compromises that enable us to reconcile these conflicting objectives are essentially based on technological developments and in-depth expertise in the subject.

But what if demand grows faster than technological performance? Here again, asking the question is already answering it, because the key to the right lighting lies in prioritizing the issues and functions you want lighting to play....
