Title Low-cost LED flashlights and market spoiling in Kenya's off-grid lighting market Type Journal Article
Year 2015 Publication Energy Efficiency Abbreviated Journal Energy Efficiency
Volume 8 Issue 2 Pages 323-337
Keywords (down) Lighting; Regulation
Abstract Market spoiling stemming from information asymmetry has slowed the adoption grid-independent technologies that replace fuel-based lighting in the developing world. End users typically first experience lighting technology innovations via flashlights. The rapid emergence of inexpensive LED flashlights is a potentially good advancement in this regard, as LED lighting can be longer-lived, have higher initial light output, and be more energy-efficient than incandescent. However, our laboratory tests and end user interviews indicate that these products often fall far short of advertised performance levels and typically fail after a few months of use. Our study of purchasing decisions by 23 Kenyan market traders given an opportunity to purchase warrantied LED lamps found that prior experience with inexpensive LED flashlights significantly reduced their probability of purchasing (p = 0.0028). As additional evidence of consumer skepticism, in a large statistical survey, we also find that willingness to pay increases significantly once an LED lighting product is directly handled and tested by the end user. If LED lighting is to achieve its potential as a superior substitute for fuel-based lighting, effective policy measures are needed to remove the information asymmetry between expected and actual performance. One such measure, independent testing and certification, has measurably increased the quality of products available in the off-grid lighting marketplace.

Title Sustainable Lighting Policies: The Contribution of Advertisement and Decorative Lighting to Local Light Pollution in Seoul, South Korea Type Journal Article
Year 2018 Publication Sustainability Abbreviated Journal Sustainability
Volume 10 Issue 4 Pages 1007
Keywords (down) Lighting; Regulation
Abstract We carried out field measurements to determine the contribution of advertisement and decorative lighting to local light pollution in Seoul. We used the lighting limits set by the “Light Pollution Prevention Act”, which regulates light pollution, as measuring criteria. Our results show that both advertisement and decorative lighting are significant contributors to local light pollution in Seoul. Thirty percent of advertisement lighting measured in our study areas exceeded the legal limits. Moreover, we found that certain types of advertisement lighting are more likely to cause light pollution than the others. In addition, 73% of the decorative lighting found in our sample areas exceeded the legal limits. Based on our findings, we suggest that local light pollution policies establish a curfew time when all advertisement and decorative lighting must be completely turned off. Such an approach is essential in reducing lighting levels in outdoor environments. Furthermore, it lessens the burden on law enforcement personnel, who otherwise must ensure that advertisement and decorative lighting levels are kept within the legal limits. In light of the ongoing debate over the role of lighting in public well-being and the sustainability of cities, the present study provides a discussion on the status and management policy of light pollution caused by advertisement and decorative lighting.

Title New nighttime roadway lighting documentation applied to public safety at night: A case study in San Antonio, Texas Type Journal Article
Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society
Volume 46 Issue Pages 101459
Keywords (down) Lighting; Public Safety; Security; Planning
Abstract Built environment and public safety professionals view street lighting as an important factor in improving the well-being of the community at night. Extant research that has examined the relationship between street lighting and public safety has found inconclusive or mixed results and has called for more extensive lighting metrics. Using new lighting measurement technologies and geographic information science, this study builds on previous work to demonstrate new metrics to consider when evaluating public safety, specifically crime and traffic accidents. Downtown San Antonio, Texas is used as a case study to explore illuminance levels on roadways and the driver’s eye, and how these metrics can be used to understand the lighting characteristics of where crime and traffic accidents occur. The findings indicate that the central downtown district in San Antonio has higher illuminance levels than the existing roadway lighting guidelines while the residential downtown neighborhoods have insufficient light levels. Statistical analysis reveals that roadway illuminance levels are higher in areas where no crime occurred and driver’s eye illuminance levels are lower in areas with no traffic accidents. The findings prove the usefulness of new lighting documentation techniques and support the importance of considering illuminance metrics when assessing crime and traffic accidents at night.

Title Effects of road lighting on motorways Type Journal Article
Year 2009 Publication Traffic Injury Prevention Abbreviated Journal Traffic Inj Prev
Volume 10 Issue 3 Pages 279-289
Keywords (down) Lighting; Public Safety; Security
Abstract OBJECTIVES: The study has three objectives. The first is to investigate how the effect of road lighting on motorway accidents varies with different weather and road surface conditions. The second is to evaluate the future benefit of road lighting as a safety measure on motorways. The third is to evaluate the need for further research in the field of motorway lighting. METHOD: This article presents a cross-sectional study of the effects of road lighting on motorways mainly in The Netherlands. The main source of data is a Dutch database of accidents covering the period 1987-2006, but British and Swedish data are also used. RESULTS: The effect of road lighting on motorways is found to be greater in The Netherlands than in Great Britain or Sweden. Reasons for this are not known. Effects are found to vary according to background characteristics and are lesser during precipitation than during fine weather and on wet road surfaces than on dry surfaces. No effect of road lighting is found during fog. Collision with light poles constitutes a large number of accidents on lit motorways and reduces the safety effect of road lighting. CONCLUSIONS: The effect of road lighting on injury accidents during darkness is found to be very high (-49%) on Dutch motorways. However, the effect seems to vary between countries. Collisions with light poles reduce the effect of road lighting. Road lighting will probably be an effective safety measures on motorways for many years. In the long term, however, the benefit of road lighting will probably be reduced along with the implementation of new vehicle and road technology. Modern technology permits a continuous adaptation of luminance levels to optimize the effect of road lighting on safety while at the same time minimizing energy consumption. However, more detailed knowledge concerning the effects of road lighting at different lighting levels is needed in order to use this technology effectively. Alternative or additional measures like LED guide lights and light road surfaces also need to be evaluated.
