Title Investigation of flashing and intensity characteristics for vehicle-mounted warning beacons Type Journal Article
Year 2018 Publication Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention
Volume (down) 119 Issue Pages 23-28
Keywords Security; Public Safety; Lighting
Abstract Reducing the potential for crashes involving front line service workers and passing vehicles is important for increasing worker safety in work zones and similar locations. Flashing yellow warning beacons are often used to protect, delineate, and provide visual information to drivers within and approaching work zones. A nighttime field study using simulated workers, with and without reflective vests, present outside trucks was conducted to evaluate the effects of different warning beacon intensities and flash frequencies. Interactions between intensity and flash frequency were also analyzed. This study determined that intensitiesof 25/2.5 cd and 150/15 cd (peak/trough intensity) provided the farthest detection distances of the simulated worker. Mean detection distances in response to a flash frequency of 1 Hz were not statistically different from those in response to 4 Hz flashing. Simulated workers wearing reflective vests were seen the farthest distances away from the trucks for all combinations of intensity and flash frequency.

Title Meeting report: the role of environmental lighting and circadian disruption in cancer and other diseases Type Journal Article
Year 2007 Publication Environmental Health Perspectives Abbreviated Journal Environ Health Perspect
Volume (down) 115 Issue 9 Pages 1357-1362
Keywords Human Health; Animals; *Circadian Rhythm; Environmental Exposure; Humans; *Lighting/adverse effects; *Neoplasms/etiology; Research; breast cancer; circadian rhythms; clock genes; lighting; melatonin; phototransduction; pineal gland
Abstract Light, including artificial light, has a range of effects on human physiology and behavior and can therefore alter human physiology when inappropriately timed. One example of potential light-induced disruption is the effect of light on circadian organization, including the production of several hormone rhythms. Changes in light-dark exposure (e.g., by nonday occupation or transmeridian travel) shift the timing of the circadian system such that internal rhythms can become desynchronized from both the external environment and internally with each other, impairing our ability to sleep and wake at the appropriate times and compromising physiologic and metabolic processes. Light can also have direct acute effects on neuroendocrine systems, for example, in suppressing melatonin synthesis or elevating cortisol production that may have untoward long-term consequences. For these reasons, the National Institute of Environmental Health Sciences convened a workshop of a diverse group of scientists to consider how best to conduct research on possible connections between lighting and health. According to the participants in the workshop, there are three broad areas of research effort that need to be addressed. First are the basic biophysical and molecular genetic mechanisms for phototransduction for circadian, neuroendocrine, and neurobehavioral regulation. Second are the possible physiologic consequences of disrupting these circadian regulatory processes such as on hormone production, particularly melatonin, and normal and neoplastic tissue growth dynamics. Third are effects of light-induced physiologic disruption on disease occurrence and prognosis, and how prevention and treatment could be improved by application of this knowledge.

Title A Crusade on HSP Amber High Mast Yields Green with Plasma Type Journal Article
Year 2015 Publication Energy Abbreviated Journal Energy Engr.
Volume (down) 112 Issue 5 Pages 12-17
Keywords Lighting; Energy; lighting technology; light-emitting plasma; lighting transition; LEP; Washington
Abstract Naval Facilities Engineering Command Northwest (NAVFAC NW) Public Works Department (PWD) Everett recently completed a lighting replacement project at Naval Station (NS) Everett, Washington, utilizing a utility energy service contract (UESC) with Bonneville Power Administration (BPA). The project replaced 74 high pressure sodium (HPS) light fixtures with modern energy saving, light-emitting plasma (LEP) fixtures atop 80-foot light poles along the piers and wharf at NS Everett. The no-glare LEP bulbs last twice as long while using less than half the power of their HPS predecessors. This project was completed at a cost of $160,000 and will result in cost avoidances in annual operating and maintenance of over $16,000, with a payback under 10 years. This UESC-financed and executed project saves one percent of the total shore energy consumption cost. Through similar efficiency projects and energy conservation efforts, NS Everett has reduced power usage by 16 percent in the past year and 40 percent since 2003.
