Greetings beloved comrades,
I have several lighted ceiling fans of the same model wired with separate, non-dimming, wall switches for the fan and light. The lights inside may be LEDs, but I haven't disassembled them yet to confirm this.
For one of the fans, switching on the fan at the wall causes the light to briefly go out, for maybe a tenth of a second, then come back on.
This strikes me as very strange. I thought maybe the inrush current for the fan was dropping the voltage enough that an LED light might turn off and then recover, but this seems unlikely.
I thought maybe there was a loose connection in the switch that would move when the switch was operated, but tapping/manipulating the switch didn't seem to have the same effect.
Any thoughts before I de-energize the circuit and start testing everything?

This isn't really an answer, but I thought I'd close the loop.
Changing the bulb to a different brand of LED bulb causes the flicker to stop.
This doesn't explain why the flicker is there to begin with, but all of the installed fans of the same model exhibit this behavior.
Ideally, I would investigate further, but time is limited.
