I’ve had my ceiling fan outfitted with these same led light bulbs for about 2 and 1/2 years. Why is one of them acting like a strobe light? For no apparent reason, the led light bulb, Sylvania LED4B10C/BLUNT/DIM/827, now has a strobe effect.

I’m no light bulb scientist, so if any of you know why this is happening, or you have a plausible theory, please leave the explanation in the comments.
