Title (down) Warm white versus neutral white LED street lighting: Pedestrians' impressions Type Journal Article
Year 2018 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology
Volume in press Issue Pages 147715351880429
Keywords Psychology; Security
Abstract The subjective impressions of pedestrians are necessary in order to decide on the appropriate colour of light to be used for street lighting. Therefore, a pilot project aimed to compare subjective evaluations of the sidewalk illumination under two street lighting installations, realised by LEDs of 3000 K (warm white) and 4000 K (neutral white), was recently conducted in Belgrade. Both installations had comparable sidewalk illuminances as well as other relevant photometric parameters. The evaluation was done through a questionnaire. A group of 139 (61 male and 78 female) respondents, all of them university students, was asked to grade both lighting installations for the sidewalk light intensity, the appearance of human faces, the colour of light and the colour rendering as well as the overall impression. According to the median values, the 3000 K LED installation was considered better than the 4000 K installation for all aspects assessed as well as the overall impression. Although the survey results convincingly showed a preference for 3000 K LEDs for this comparison, additional research is needed using a more representative sample of people and a wider range of locations before a definite conclusion can be reached.

Title (down) Walking the creek: reconnecting place through light projection Type Journal Article
Year 2019 Publication Geographical Research Abbreviated Journal Geographical Research
Volume 57 Issue 3 Pages 263-274
Keywords Society; Psychology; Australia; public amenity; placemaking; light projection
Abstract In this paper, we explore how a light projection sought to convey a range of qualities: conviviality, a sense of place, playfulness, defamiliarisation, and the affective and sensory capacities that were experienced through walking in the distinctive, liminal realm of Bendigo Creek in Victoria, Australia. The projection aspired to solicit a sensory and affective empathy that chimed with the experiences of an earlier event in which dozens of pedestrians were filmed walking in the creek. The projection contributed to a local campaign to reappraise the much‐maligned creek as a local public amenity. We discuss the productive potential of solitary and collective walking and, subsequently, the attributes of the projection in its static and mobile manifestation. In so doing, we suggest that publicly engaged, inclusive, creative practice can offer potent place‐making possibilities.

Title (down) Waddling on the Dark Side: Ambient Light Affects Attendance Behavior of Little Penguins Type Journal Article
Year 2016 Publication Journal of Biological Rhythms Abbreviated Journal J Biol Rhythms
Volume 0748730415626010 Issue Pages
Keywords Animals; birds; penguins; attendance; little penguin; Eudyptula minor; Phillip Island; Australia; photobiology; seabirds
Abstract Visible light on Earth largely comes from the sun, including light reflected from the moon. Predation risk is strongly determined by light conditions, and some animals are nocturnal to reduce predation. Artificial lights and its consequent light pollution may disrupt this natural behavior. Here, we used 13 years of attendance data to study the effects of sun, moon, and artificial light on the attendance pattern of a nocturnal seabird, the little penguin Eudyptula minor at Phillip Island, Australia. The little penguin is the smallest and the only penguin species whose activity on land is strictly nocturnal. Automated monitoring systems recorded individually marked penguins every time they arrived (after sunset) at or departed (before sunrise) from 2 colonies under different lighting conditions: natural night skylight and artificial lights (around 3 lux) used to enhance penguin viewing for ecotourism around sunset. Sunlight had a strong effect on attendance as penguins arrived on average around 81 min after sunset and departed around 92 min before sunrise. The effect of moonlight was also strong, varying according to moon phase. Fewer penguins came ashore during full moon nights. Moon phase effect was stronger on departure than arrival times. Thus, during nights between full moon and last quarter, arrival times (after sunset) were delayed, even though moonlight levels were low, while departure times (before sunrise) were earlier, coinciding with high moonlight levels. Cyclic patterns of moon effect were slightly out of phase but significantly between 2 colonies, which could be due to site-specific differences or presence/absence of artificial lights. Moonlight could be overridden by artificial light at our artificially lit colony, but the similar amplitude of attendance patterns between colonies suggests that artificial light did not mask the moonlight effect. Further research is indeed necessary to understand how seabirds respond to the increasing artificial night light levels.

Title (down) Voices for the darkness: online survey on public perceptions on light pollution as an environmental problem Type Journal Article
Year 2013 Publication Journal of Integrative Environmental Sciences Abbreviated Journal Journal of Integrative Environmental Sciences
Volume 10 Issue 2 Pages 127-139
Keywords environmental management; light pollution; public perceptions; survey; public policy
Abstract Light pollution is increasingly affecting ecosystems and human health. We present results from an online survey aimed to chart what aspects of lighting are considered harmful and how light pollution is perceived by the public. We focus on affluent societies by using Finland as an example of a northern industrialised country. The survey generated 2053 responses, particularly from well-educated urban persons living in residential areas and interested in astronomy or environmental issues. The results show that the lighting of residential areas and lighting serving traffic are considered the most common sources of light pollution while commercial lighting is perceived as the most annoying form of light use. Respondents commonly considered light pollution as a disturbance for outdoor recreation and relaxation. The results suggest that the ecological and health effects of light pollution emphasised by the research are poorly known by the people emphasising the aesthetic aspects. The results indicate relatively wide but passive acceptance for policy measures aimed at reducing light pollution.
