The following map shows light intensity distribution on local area around the site. Mostly residential areas are bright during nights and commercial focal points are not crowded and probably consequently they don't have attractive lighting.
David Batchelor's works, which depicts light spectrum in Xmas lighting and different installations from Washington to Barcelona. His work Ten silhouettes in London underground station can clearly show changes in mood while passing by them.
I also found Carlo Bernardini's works very inspiring specially in designing light for landscape. Lighting in landscape is not limited to post lamps or lights along a road. to making new spaces, it's better to use sculpture lights.
Currently I'm working on an urban project in Chelmsford, Marconi site.
I thought the site basically needs lighting up, in an efficient way. So I'm looking at artists who have worked on light installations and lights in different colours. I've looked at some works by Tadao Ando, Anish Kapoor, David Batchelor and Dan Flavin.
Dan flavin:
Anish Kapoor's installations are not mainly about lighting up at first sight, but as these examples have a reflective surface, they work great in urban open space:
As we move through a place with different colours around us, we'll probably experience different emotions unconsciously. Looking at colour wheel may show how different we feel by different colours. For instance yellow attracts eyes, making people feel hungry(!!!) or light purple is mostly known for its spiritual characters.
