ABSTRACT
This chapter provides a better understanding on the question of how new rationales and ideas on lighting relate to adjustments and changes in local institutional contexts. The chapter draws conceptual guidance from sociologically grounded and dis-cursive institutionalist approaches that lend "insight into the role of ideas and discourse in politics, while providing a dynamic approach to institutional change". It analyses three different case studies in Germany. The first empirical example studies the process of developing a concept outlining parameters to meet EU climate and energy protection endeavours for both the provision and the modernisation of street lighting. In Berlin, internal pressures initially challenged the institutional frameworks. In the case of the lighting conflict concerning the media screens of the O2-World, institutional dynamics emerged from the inadequacy of the existing formal rules to meet the particularities of LED media screens. Embedding new ideas in new institutions is strongly shaped by different local contexts, problems, perceptions and implementation habits.
