Webinar: Flicker with Naomi Miller

IES Section Webinar
  • March 11, 2021
    7:00 pm - 8:00 pm

LEDs are more likely to produce distracting flicker than the light sources of yore. Yet, it’s still very difficult to anticipate which products will flicker (formally called Temporal Light Artifacts), which luminaire-control pairings could be problematic, and once you have flicker on a jobsite, how to fix it. Are there standard flicker metrics yet? Are there meters we can use? How do we spot flicker? Why is it so hard to make flicker-free dimming? Is it the fault of the dimmer or the driver? How many people does this affect? Where do we need to pay careful attention to this issue, and where is it far less likely to cause concern?

This talk is intended to arm designers with tools to fight flicker on their projects. They will learn how to spot and measure flicker, which populations are most affected, and they will see through demonstrations what the different ranges of flicker look like.

Naomi MillerMs. Naomi Miller is a designer/scientist in the solid-state lighting program at Pacific Northwest National Laboratory in Portland OR. Working to bridge the gap between technology and application, Miller promotes the wise use of LEDs, and works with industry to overcome the hurdles where LEDs are not ready for prime time. Miller has received over 30 architectural lighting design awards for projects ranging from churches to university science buildings, boutique hotels, supermarkets, and parking lots. She chaired the IES Quality of the Visual Environment committee for 8 years and was a principal member of the writing team for Light + Design: A Guide to Designing Quality Lighting for People and Buildings (DG-18-08). She is a Fellow of the IES and Fellow of the IALD.
