Obviously that would be the case when everything is working. FWIW, I found that even my original 330uf cap for my lighting modules was sufficient to kill almost any flicker. I increased it to 470, and briefly to 680 for the production runs. With the component shortages, I can no longer get the 680 caps, so I'm back to the 470.
