One light fitting has caused me problems, had to fit load capacitor as would not switch off, and shimmered when on all LED G9 bulbs, wife got 5 replacements which were physically much larger, and one failed after a day, and today I decided to strip the faulty bulb to see how made, but stage one and I could see a capacitor not soldered in, so thought try re-soldering and yes it worked. So not completely stripped.
But I could clearly see a full wave rectifier, and an electrolytic capacitor and I assume a paper one, the latter was one not connected. So it seems reasonable to assume the electrolytic was after the rectifier pity did not take picture.
However it seems reasonable to assume the electrolytic capacitor was reason for no shimmer with these bulbs. Marking did not even show wattage, 220 to 240 volt CE marked and that was it, seem bright for a G9 this design but as large as a E14 candle bulb, could not fit covers.
So my daughter complained about living room lights says it gives her a headache, so wonder it there is a way to test if the bulb has the electrolytic capacitor or not? I can see why the originals had a problem, simply not room to fit an electrolytic capacitor. But is the only way to suck and see, there must be some way to test?
