Sloane, M., Slater, D., & Entwistle, J. (2016). Tackling Social Inequalities in Public Lighting.
Abstract: 2This report is based on research findings of the Configuring Light/Staging the Social research programme (CL) based at the London School of Economics and Political Science (LSE), as well as on discussions of the Configuring Light expert working group. Consisting of high-profile experts and stakeholders in the fields of design, planning and policy-making, this group was established by CL to develop a new agenda for tackling social inequalities in public lighting. Members of the working group are listed at the end of this document.This project was run by the LSE-based Configuring Light/Staging the Social research programme and funded by LSE Knowledge Exchange and Impact funding.

Abstract: The lack of lighting planning for internal and external illumination of buildings contributes to wasting energy and to the issue of light pollution. This will be demonstrated with research from the ground and by analysis of images, taken with detectors on satellites, the International Space Station or planes. Besides large area floodlighting from airports or sports facilities, facade illumination is the most important contributor. The effects of malpractice versus sustainable lighting planning solutions will be demonstrated with some examples in cities like Bonn, Strasbourg, Athens and Thessaloniki. Further examples in the countryside will demonstrate lighting practice in the German star park Biosphere Reserve Rhön. Facade lighting planning, considering optimal alignment, the intensity and the colour quality of the illumination, will contribute to reducing light pollution and thus waste of energy and will increase human comfort at the same time.
Experience shows that unilateral promoting energy efficiency will finally result in more extended use of energy, which is known as rebound effect. In addition the small size and long lifetime of the modern solid state lighting will result in an increased use even in remote places thereby emitting more artificial light into the natural night. This does not only affect the energy use, but also the biological rhythms of animals and human beings.
More interdisciplinary criteria for a sustainable lighting with reduced light pollution will be discussed based on the observations including data provided by the EU-network “Loss of the Nightâ€-Network (EU-COST Action ES1204 LoNNe).

Abstract: Recent study in vision science has shown that blue light in a certain frequency band affects human circadian rhythm and impairs our health. Although applying a light blocker to an image display can block the harmful blue light, it inevitably makes an image look like an aged photo. In this paper, we show that it is possible to reduce harmful blue light while preserving the blue appearance of an image. Moreover, we optimize the spectral transmittance profile of blue light blocker based on psychophysical data and develop a color compensation algorithm to minimize color distortion. A prototype using notch filters is built as a proof of concept.

Beck, W., & Gobatto, C. (2016). Effect of high wavelengths low intensity light during dark period on physical exercise performance, biochemical and haematological parameters of swimming rats. Acta Physiol Hung, 103(1), 112–120.
Abstract: Nocturnal rodents should be assessed at an appropriate time of day, which leads to a challenge in identifying an adequate environmental light which allows animal visualisation without perturbing physiological homeostasis. Thus, we analysed the influence of high wavelength and low intensity light during dark period on physical exercise and biochemical and haematological parameters of nocturnal rats. We submitted 80 animals to an exhaustive exercise at individualised intensity under two different illuminations during dark period. Red light (> 600 nm; < 15lux) was applied constantly during dark period (EI; for experimental illumination groups) or only for handling and assessments (SI; for standard illumination groups). EI led to worse haematological and biochemical conditions, demonstrating that EI alone can influence physiological parameters and jeopardise result interpretation. SI promotes normal physiological conditions and greater aerobic tolerance than EI, showing the importance of a correct illumination pattern for all researchers that employ nocturnal rats for health/disease or sports performance experiments.
