A very Interesting read.  Imagine being able to save £50k per year in energy.  Some of the projects are flamboyant and wasteful in the lighting design to say the very least.

The Eiffel Tower is a very well known landmark that really needs little lighting. Then we have the hotels in the Middle East and Asia, which attract people because of the style and elegance of architecture used not because of the overlit exterior lighting.  Just make sure you shut the curtains to keep the light out!
