Do you know what is a TEDMED?
TED (Technology, Entertainment, Design) is a media organization which posts talks online for free distribution, under the slogan “ideas worth spreading”. TED was founded in February 1984 as a conference, which has been held annually since 1990. TED’s early emphasis was technology and design, consistent with its Silicon Valley origins, but it has since broadened its focus to include talks on many scientific, cultural, and academic topics.

TEDMED is a talk focused instead on medicine.

Mariana Figueiro, Light and Health Program Director at the Lighting Research Center (LRC) and Professor at Rensselaer Polytechnic Institute, reveals surprising facts about the effects of light – its presence, its absence, and its patterns – on human health.

Presented by Lighting Research Center scientists Dr. Mark Rea and Dr. Mariana Figueiro on March 15, 2017, this webinar addresses the American Medical Association (AMA) report cautioning the public about the use of In-Ga-N based LEDs. This webinar provides: practical, scientific advice to address the issues raised in the AMA report; direction on correctly and accurately measuring and specifying indoor and outdoor lighting; and guidance to address the problems of misapplying short-hand metrics to the topic of the health and environmental impacts of light and lighting. Thank you to the participants at more than 200 locations around the world who took part in this webinar!
