  Title Lighting Professionals versus Light Pollution Experts? Investigating Views on an Emerging Environmental Concern Type Journal Article
  Year 2019 Publication Sustainability Abbreviated Journal Sustainability  
  Volume 11 Issue 6 Pages 1696  
  Keywords Lighting; Society  
  Abstract Concerns about the potential negative effects of artificial light at night on humans, flora and fauna, were originally raised by astronomers and environmentalists. Yet, we observe a growing interest in what is called light pollution among the general public and in the lighting field. Although lighting professionals are often critical of calling light ‘pollution’, they increasingly acknowledge the problem and are beginning to act accordingly. Are those who illuminate joining forces with those who take a critical stance towards artificial light at night? We explore this question in more detail based on the results of a non-representative worldwide expert survey. In our analysis, we distinguish between “lighting professionals” with occupational backgrounds linked to lighting design and the lighting industry, and “light pollution experts” with mostly astronomy- and environment-related professional backgrounds, and explore their opposing and shared views vis-à-vis issues of light pollution. Our analysis reveals that despite seemingly conflicting interests, lighting professionals and light pollution experts largely agree on the problem definition and problem-solving approaches. However, we see diverging views regarding potential obstacles to light pollution mitigation and associated governance challenges.

  Title Making space for 'the social': connecting sociology and professional practices in urban lighting design Type Journal Article
  Year 2019 Publication The British Journal of Sociology Abbreviated Journal Br J Sociol  
  Volume 70 Issue 5 Pages 2020-2041  
  Keywords Sociology; Society; Lighting  
  Abstract Lighting is increasingly recognized as a significant social intervention by both lighting professionals and academic social scientists. However, what counts as 'the social' is diverse and contested, with consequences for what kind of 'social' is performed or invented. Based on a long-term research programme, we argue that collaboration between sociologists and lighting professionals requires negotiating discourses and practices of 'the social'. This paper explores the quality and kinds of spaces made for 'the social' in professional practices and academic collaborations, focusing on two case studies of urban lighting that demonstrate how the space of 'the social' is constrained and impoverished by an institutionalized division between technical and aesthetic lighting. We consider the potential role of sociologists in making more productive spaces for 'the social' in urban design, as part of the central sociological task of 'inventing the social' (Marres, Guggenheim and Wilkie 2018) in the process of studying it.

  Title Light dominates colour preference when correlated colour temperature differs Type Journal Article
  Year 2018 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume 50 Issue 7 Pages 995-1012  
  Keywords Vision; Lighting  
  Abstract Colour preference for lighting is generally influenced by three kinds of contextual factors, the light, the object and the observer. In this study, a series of psychophysical experiments were conducted to investigate and compare the effect of certain factors on colour preference, including spectral power distribution of light, lighting application, observers’ personal colour preference, regional cultural difference and gender difference. LED lights with different correlated colour temperatures were used to illuminate a wide selection of objects. Participant response was quantified by a 7-point rating method or a 5-level ranking method. It was found that the preferred illumination for different objects exhibited a similar trend and that the influence of light was significantly stronger than that of other factors. Therefore, we conclude that the light itself (rather than, e.g. the objects that are viewed) is the most crucial factor for predicting which light, among several candidates with different correlated colour temperatures, an observer will prefer. In addition, some of the gamut-based colour quality metrics correlated well with the participants’ response, which corroborates the view that colour preference is strongly influenced by colour saturation. The familiarity of the object affects the ratings for each experiment while the colour of the objects also influences colour preference.

  Title Changing the colour of night on urban streets – LED vs. part-night lighting system Type Journal Article
  Year 2019 Publication Socio-Economic Planning Sciences Abbreviated Journal Socio-Economic Planning Sciences  
  Volume in press Issue Pages 100692  
  Keywords Energy; Planning; Economics; United Kingdom; LED; Lighting  
  Abstract Many cities in the United Kingdom are upgrading the streetlights to white light-emitting diode (LED) lamps for reducing the electricity costs and attaining the sustainable energy solutions. Installation of LED lamps on urban street requires higher installation costs and a long-term period to payback benefits of replacing outdated streetlights in terms of energy savings and costs. To achieve the short-term energy efficiency of urban street lighting, city councils sometimes adopt the part-night lighting system particularly in the residential areas. The Coventry City Council recently replaced 29,701 existing sodium lights with LED lamps. This paper performs the economic analyses to understand the feasibility of two street lighting systems: LED lamps and ‘part-night’ lightings on the Coventry streets during the twenty-year period assuming the return period of investment is twenty years. The projection of energy consumption and costs for LED lamps and part-night lighting systems shows that electricity can be saved by 44% and 21% comparing to current electricity usages, respectively. Considering the budgetary constraints of Coventry City Council, this paper concludes that the part-night lighting system may be beneficial in short-term period, but it is economically feasible to replace the existing lower efficiency lights with LED lamps.
