"Recommending practices for modulating current in High Brightness LEDs for mitigating health risks to viewers"

Our Purpose:

Bring together a community of lighting environmental psychologists, lamp designers, LED driver designers, and LED lamp users to 1) discuss health concerns for modulating frequencies/flicker in LED lighting and 2) provide recommended modulating frequency practices to aid the LED lamp design in different applications.

Public Documents:

Our goal is to create a transparent, open process. In order to do this, IEEE Standards P1789 will post various documents and openly solicit comments from the public from the following web page link:
