Join us for a virtual presentation on LED Flicker Metrics presented by Naomi Miller of the Pacific Northwest National Laboratory. Thank you to our generous sponsor LightArt!

Event Description:
LED’s are a terrific light source with only a few shortcomings. Potential flicker, or more precisely, temporal light artifacts (TLA), is one of them. The response to the light modulation can range from none to mild annoyance, to catastrophic. There are three distinct forms of TLA, two of which are tricky to characterize with metrics for prediction and measurement. This talk will address the fundamentals of the science, the possible metrics, and some simple tools you can use to detect and avoid flicker.

Learning objectives:


  1. Define and Describe “Flicker” Temporal Light Artifacts (TLA),
  2. Discuss the ramifications of TLA in our built environments,
  3. Instruct on best available metrics for measuring and documenting TLA, and
  4. Advise on approaches to minimize TLA in lighting application.

Naomi MillerNaomi Miller has been a Senior Lighting Research Scientist since joining PNNL in 2009. Ms. Miller’s work focuses on bridging the knowledge gap between technology and application. She works with clients and stakeholders to overcome the hurdles facing the adoption of energy efficient lighting products. Her research also focuses on lighting quality and the human impacts of light.

Prior to coming to PNNL, Ms. Miller was the Principal of Naomi Miller Lighting Design in Troy, New York. With over 30 architectural lighting design awards, Ms. Miller is a nationally recognized expert in the field of lighting. She chaired the Illuminating Engineering Society’s (IES) Quality of the Visual Environment committee for 8 years and was a principal member of the writing team for the IES’s Light + Design: A Guide to Designing Quality Lighting for People and Buildings. She currently serves on the Illuminating Engineering Society’s Board of Directors and is both a Fellow of the IES and the International Association of Lighting Designers (IALD).
