Title Making sense of diodes and sodium: Vision, visuality and the everyday experience of infrastructural change Type Journal Article
Year 2019 Publication Geoforum Abbreviated Journal Geoforum
Volume 103 Issue Pages 95-104
Keywords Lighting; visual sensorium; United Kingdom
Abstract The recognition of vision as a powerful register for organising urban space locates lighting technologies at the heart of urban experience. Recently, scholars have established that lighting technologies shape not just what we see but how we see, drawing attention towards light as that ‘with which we see’. This article shifts attention from the role of lighting in shaping what and how people see, to how people make sense of changes to their visual sensorium—from what lighting infrastructures do to what is done with them. By following older residents living in the London Borough of Newham along routine travels on foot at night, I demonstrate how they make sense of the Council’s initiative to upgrade their 19,500 street-lamps with Light Emitting Diodes. I demonstrate how such infrastructural change exposes an uneven geographical distribution of and access to light and darkness with potentially detrimental consequences for the formation of public life after dark. Recognising how light infrastructures are reframed through everyday life, I demonstrate how LEDs do not necessarily produce their desired effects and how light clutter and light bleed might contribute to producing nocturnal atmospheres where people feel safe and confident. Broadening the understanding of how different technologies and light sources are important for the formation of inclusive nocturnal publics the article sets out a ‘politics of visibility’ that recognises the role of lighting in creating visibility for and of residents.

Title Optimizing Lighting of Rural Roads and Protected Areas with White Light: A Compromise among Light Pollution, Energy Savings, and Visibility Type Journal Article
Year 2019 Publication Leukos Abbreviated Journal Leukos
Volume in press Issue Pages 15502724.2019.1574138
Keywords Lighting; Energy; Skyglow; LED
Abstract The broad implementation of light emitting diode (LED) light sources in public lighting has become a revolution in recent years. Their low power consumption and good performance (extremely low onset time, long lifetime, high efficacy) make LEDs an optimal solution in most outdoor applications. In addition, the white light emitted by the vast majority of LEDs used in public lighting and their good color rendering improve well-being, comfort, and safety in cities, especially in commercial zones and urban centers. However, regulations on light pollution that have been developed in some countries in parallel to the introduction of LED lighting impose strong constraints to white light emission, which is present due to the higher Rayleigh scattering of short wavelengths. These regulations request filtering blue wavelengths in some protected areas and thus limit the projects to high- or low-pressure sodium sources or amber LEDs. In this work, the pros and cons of white and amber LED lighting in rural areas are analyzed and compared through simulations made on a typical rural lighting situation and considerations based on efficiency, visual performance, nonvisual effects, and light pollution. The most important conclusion is that Rayleigh scattering seems to prevail in the current considerations on light pollution, whereas other important aspects affecting safety and sustainability are are not considered. Accurate designs can decrease light pollution without constraints against white LEDs. The objective of this work is to provide evidence leading to consider light pollution from a more general perspective in the benefit of humans and the environment.
