Title Influence of horizon elevation on the sea-finding behaviour of hatchling flatback turtles exposed to artificial light glow Type Journal Article
Year 2015 Publication Marine Ecology Progress Series Abbreviated Journal (down) Mar. Ecol. Prog. Ser.
Volume 529 Issue Pages 279-288
Keywords Animals; Hatchling orientation; Artificial lighting; Horizon elevation; Marine turtle; Conservation management; Elevation; Industry; Coastal development; Sea turtle; Sea turtle conservation
Abstract Marine turtles are threatened globally by increasing coastal development. In particular, increased artificial lighting at the nesting beach has the potential to disrupt turtle breeding success. Few published data exist regarding the behaviour of the flatback turtle Natator depressus, a species endemic to Australia, in response to artificial light. Given the ongoing industrialisation of the Australian coastline, this study is a timely investigation into the orientation of flatback hatchlings exposed to light glow produced by lighting typically used in industrial settings. We recorded the orientation of hatchlings at the nesting beach on Barrow Island, Western Australia, exposed to 3 types of standard lighting — high-pressure sodium vapour (HPS), metal halide (MH), and fluorescent white (FW)—at 3 different intensities. The light array was positioned either behind a high dune (producing a high, dark silhouette; 16° elevation), or in a low creek bed (producing a low silhouette and bright horizon; 2° elevation). At medium and high light intensities of all 3 light types, hatchlings were significantly less ocean-oriented when exposed to light at 2° elevation compared to 16° elevation. This difference remained with glow from low-intensity MH light; however, there was no significant difference in orientation of hatchlings exposed to low- intensity HPS and FW light glow at either elevation. Our study emphasises the importance of horizon elevation cues in hatchling sea-finding. Since all species of marine turtles show similar sea-finding behaviour, our results have important implications for management of lighting adjacent to turtle nesting beaches in Australia and elsewhere, as coastal development continues.

Title Observing other pedestrians: Investigating the typical distance and duration of fixation Type Journal Article
Year 2014 Publication Lighting Research and Technology Abbreviated Journal (down) Lighting Research and Technologying Res & Tech
Volume 47 Issue 5 Pages 548-564
Keywords traffic safety; pedestrians; roadway lighting; visibility; light at night
Abstract After dark, road lighting should enhance the visual component of pedestrians’ interpersonal judgements such as evaluating the intent of others. Investigation of lighting effects requires better understanding of the nature of this task as expressed by the typical distance at which the judgement is made (and hence visual size) and the duration of observation, which in past studies have been arbitrary. Better understanding will help with interpretation of the significance of lighting characteristics such as illuminance and light spectrum. Conclusions of comfort distance in past studies are not consistent and hence this article presents new data determined using eye-tracking. We propose that further work on interpersonal judgements should examine the effects of lighting at a distance of 15 m with an observation duration of 500 ms.

Title Road lighting and energy saving Type Journal Article
Year 2009 Publication Lighting Research and Technology Abbreviated Journal (down) Lighting Research and Technology
Volume 41 Issue 3 Pages 245-260
Keywords public policy; roadway lighting; energy consumption
Abstract This paper examines how the lighting of roads in the UK might be changed so as to preserve the benefits while minimising energy consumption. It is divided into four sections, these being changes in technology, changes in patterns of use, changes in standards and contracts and changes in the basis of design. Useful changes in technology and patterns of use are available now, but their use will raise the question as to whether or not environmental considerations can override conventional financial constraints. Changes in standards and the basis of design are much more long term. Comparisons of road lighting standards used in different countries show significant differences that deserve examination. As for the basis of design, consideration of the importance of light to fatal and personal injury accidents of different types suggests that road lighting should be concentrated where pedestrians are common, not where speeds are highest. Ultimately, considering carefully what problem road lighting is intended to solve and whether or not road lighting is the best answer is the key to minimising the energy consumption of road lighting without diminishing road safety.

Title Residents' perceptions following retrofitting of residential area outdoor lighting with LEDs Type Journal Article
Year 2013 Publication Lighting Research and Technology Abbreviated Journal (down) Lighting Research and Technology
Volume 45 Issue 5 Pages 568-584
Keywords *Lighting; outdoor lighting; LED; light emitting diode; lighting levels; public opinion
Abstract The use of light emitting diodes (LEDs) in outdoor lighting has energy-saving potential, but users’ responses to this light source are largely unknown. An intervention study in two residential areas compared conventional lighting installations (high pressure sodium in Area 1 and high pressure mercury in Area 2) to a retrofitted LED-alternative regarding residents’ perceptions of quality of light, visual accessibility and danger. Moreover, energy use was calculated. Residents’ (N = 60) visual accessibility improved and perceived danger remained low in both areas after retrofitting. In Area 2 the perceived quality of light increased, whereas in Area 1 the results were mixed. The retrofitted application reduced energy use by 41–76% and might be a feasible alternative to conventional outdoor lighting in relatively safe areas.

Title A study of atmosphere perceptions in a living room Type Journal Article
Year 2014 Publication Lighting Research and Technology Abbreviated Journal (down) Lighting Research and Technology
Volume 47 Issue 5 Pages 581-594
Keywords lighting; indoor lighting; perception; Chinese; Dutch; aesthetics
Abstract An experiment has been carried out to investigate the effect of lighting on the perception of atmosphere in a living room, using three types of light sources: halogen, fluorescent and LED lamps. In a psychophysical experiment, 29 native Chinese observers assessed eight lighting conditions having different luminances and correlated colour temperatures. For each condition, 71 scales were employed using the categorical judgment method. Factor analysis identified two underlying dimensions: liveliness and cosiness. This agrees with those found by Vogels who used Dutch observers to assess atmosphere perception. Both observer groups also agreed that an increase of luminance would make the room more lively. However, there were also some disagreements such as a higher CCT source would make the room more lively for Chinese observers but less lively for Dutch observers.
