GUV Lighting: Benefits and Challenges for Lighting Designers

October 29, 2020 @ 4:00 pm – 5:30 pm
Virtual Meeting - Login information provided upon registration
Edward Bartholomew

During this COVID-19 Pandemic, facility owners and managers have sought solutions for making their buildings safe for occupants.  Germicidal ultraviolet lighting (GUV) has been understood as an effective disinfectant since the 1930s, and recent research has confirmed that the SARS-CoV-2 virus which causes COVID-19 is effectively made inactive with UV-C light[1].   The biggest issue is how best to harness GUV light to fight this pandemic and the spread of the virus.  What is the role of GUV light to protect human health in buildings?

A panel of experts will present the benefits and challenges of GUV lighting from the perspective of scientific research, real-world applications and GUV lighting manufacturer.  This presentation will answer critical questions regarding GUV lighting including:  What are the best applications of GUV in buildings?  How is GUV light disinfection effectiveness measured?  What is the most effective GUV spectral range for fighting COVID-19?  Should lighting designers implement GUV lighting into their designs?  What are the right specification requirements for GUV lighting?
