Printer steppers causing lights to flicker
I've noticed for awhile now that whenever my Ender 3 S1 Pro is running, some of the lights on the same circuit will flicker seemingly in time with changes in X or Y stage movement. I'd guess that it's a combination of these stages causing minor voltage spikes/dips when they accelerate, and certain cheaper LED bulbs don't tolerate those spikes/dips well.
Has anyone else experienced this and implemented a good fix? It seems like some kind of power smoothing/conditioning filter plugged in between the printer and the wall would help isolate it. Most of those devices seem designed to isolate the device from fluctuations in the mains, and I'm not sure if it generally works both ways (seems like it should...)
Googling around most people are blaming similar issues on poor wiring, which I suppose could be the case even though this is a newer house. But I see very little in terms of actual proven effective fixes, even though it sounds pretty straightforward on its face.
Advice / thoughts?
A fun thing that happened at work...
Printing some PETG did not go as planned

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.

Maybe filament type doesn't matter much here, but I'd rather not come out to one of the lights having fallen on my car if I can help it 😅
I think the main considerations are just temperature and stiffness. It can get up to about 85F in the garage on the hottest summer days, and probably a few degrees warmer by the ceiling. The lamps are cheap LED tubes, so the metal housing only gets slightly warm to the touch (say 90-100F or so). I know PLA is a bit stiffer at room temp, but I'm worried it might soften too much at the worst case of warm temperatures.
Any thought
What is the last thing you printed?
I'm mostly into printing functional stuff. Last thing I designed and printed was a fume extractor for soldering.
