Panel Discussion on LED Street Lighting Conversion and Circadian Health Sleep Cycles

The Cambridge Public Health Department and Cambridge Electrical Department will host a panel discussion to review the LED street lighting conversion and to discuss the larger issues surrounding  circadian health (sleep cycles) Wednesday, Dec. 17, 7 p.m., Citywide Senior Center, 806 Mass. Ave., Cambridge.

The conversion to LED street lighting has been very successful in large cities across the US and Europe and has been a crucial part of the effort to reduce energy use at the municipal level.  The panelists will offer a brief update on the LED street lighting project and will also broaden the discussion to examine the larger context of artificial lighting from all sources and the effects of post-dusk lighting on our sleep cycles.  There will be time for questions to the panel after a brief overview of these topics. 

Overview of Panelists:

Steven W, Lockley, Harvard Medical School
Dr. Lockley is a Neuroscientist in the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital and an Associate Professor of Medicine in the Division of Sleep Medicine, Harvard Medical School. He is also a Professor in the School of Psychological Sciences at Monash University in Melbourne, Australia. He received his PhD in 1997 from the University of Surrey after studying circadian rhythms in the blind. He has 20 years of experience on sleep and circadian rhythm research, and is a specialist in the effects of light on the circadian pacemaker and other ‘non-visual’ responses to light. He advises NASA on jetlag and shiftwork, including use of lighting to help circadian adaptation, alertness and promotion of sleep. He has published more than 100 original reports, reviews, chapters and editorials on sleep and circadian rhythms and his research is funded by NIH, NASA, DOD and others. He recently co-authored 'Sleep: A Very Short Introduction' from Oxford University Press.
