Alp Durmus is a Lighting scientist and assistant professor of architectural engineering at Penn State. He came on the show to discuss his research in optimization of lamp color; reducing light use by aiming for the most reflectivity of the object you’re lighting.

We care more about seeing things than we care about energy use, the idea of saving power and making things look better is an appealing one, but are his methods too complicated to apply in the field?

Aside from our own struggles to make the most of IES TM-30, we discuss provoking reactions with light alone, the role of marketing, why quality means something different to each of the different professions in lighting, and the ethics of manipulating people with lighting systems.
