The past few years have elevated employee wellbeing from a nice-to-have benefit to a critical business priority. The right lighting ensures building occupants not only see well but feel and perform well. This session is intended to make sense of the correlation between traditional LED office lighting and biological darkness. Presenters will discuss melanopic lighting in detail, to help attendees: 1) understand how they can apply it in their designs; 2) overcome the limitations of standard LEDs; and 3) promote healthy, comfortable indoor environments.

NOTE: Basic understanding of spectra and optical characteristics of LED lighting for/in office environments is recommended

Learning Objectives

  1. Define melanopic lighting as it pertains to human-centric lighting.
  2. Learn how to evaluate LED spectra and lighting applications to eliminate biological darkness for building occupants.
  3. Get a glimpse into how specifiers can use a minimum melanopic EDI of 250lx to promote optimal physical/mental health and performance in indoor environments.
  4. Analyze the impact of daylight on biological factors, specifically, the role it has on sleep quality.
