Data showing any safety effects in roadway lighting applications from substituting broad-spectrum LEDs for incumbent sodium or mercury vapor luminaires are limited. This presentation will provide an overview of a new PNNL study investigating whether converting to LED roadway lighting suggests any discernible influence on driving safety. PNNL is partnering with the Delaware Valley Regional Planning Commission and Virginia Tech Transportation Institute on this project that includes more than 60 municipalities in the Philadelphia region.
Webinar participants are eligible for one (1) IES Continuing Education Unit (CEU).
The Illuminating Engineering Society (IES, est. 1906) and the International Ultraviolet Association (IUVA, est. 1999) have partnered to assemble experts in the measurement of ultraviolet C-band emissions (UV-C) to develop American National Standards for the measurement and characterization of UV-C device performance.
Congratulations to the IALD and to each designer/design team who were more than deserving of being recognized in last night's IALD International Lighting Design Awards virtual ceremony. The IALD executed a very professional and inspiring show that sets the bar for virtual events moving forward.

One of the most important aspects of visual comfort and lighting quality is the restriction and elimination of glare. With the advancement of LED technology, glare has received renewed interest. But what makes it challenging to create a simple metric that accurately predicts the perception of glare? This webinar will cover the basics of glare, methods and research challenges when investigating glare and creating metrics, and the importance of research in this area. It will also cover work of the Discomfort Glare in Outdoor Nighttime Environments (DGONE) committee including the glare demonstration conducted during the 2019 IES Annual Conference.
