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.
