Yesterday, LightNOW published a guest blog post by Jim Brodrick, DOE’s SSL Program Manager, on a new IEEE recommended practice on LED flicker. As metrics, IEEE uses % flicker, operating frequency and flicker index. A graphic is provided that plots % flicker relative to the light source’s operating frequency. Color shading reveals safe and low-risk [...]
