ABOUT THE DOCTORAL THESIS: A lighting technology, design and policy solution for Bogotá’s informal settlements will be presented that is based on an ethnographic night-time study, laboratory measurements, a luminaire prototype development and computer calculations. Moreover, the transferability of this new lighting approach to informal settlements in other countries will be explored.
