Light is a fundamental element of our existence, but we need to learn a second language of light if we are to share this amazing gift with the world. Join David K. Warfel for a romp through the lighting industry where no one is safe from over-simplification and pithy remarks but where everyone can laugh a little and see the proverbial light at the end of the tunnel.

A look into how the ASHRAE 90.1 lighting model works, and the inputs and outputs of the model.

COVID-19 has changed the lighting profession. With new interest in GUV, changes in our work environments, and projections about the future - these five courses provide insight into who we are, how we light, and what it means to practice lighting in the midst of a global pandemic.

This presentation offers an overview of DG-1 including various aspects of the color & light relationship, like Color Rendering, CCT, and TM-30.

Dynamic lighting unlocks a whole new layer of lighting capability for lighting designers and engineers, but do you know how to use it? What applications is it appropriate for and what can it be used to do? This presentation will explore some innovative ways to use dynamic light and showcase some unconventional examples.

Bruce Bugbee reviews the emerging evidence that far-red photons (700-750) have photosynthetic activity and should be included in our definition of photosynthetic photons. This has profound implications for all of plant science.

Seven presenters bring you different perspectives of the application and research of Germicidal Ultraviolet (GUV) Disinfection.

This webinar will preview draft provisional guidelines and target values developed by the IES TLM committee to raise awareness and solicit input and discussion with dimmer, driver, and luminaire manufacturers.
