Nothing special. Usually Cree, or whatever the private labels are at Lowes and HD. We have some Sylvania floods outside. Eight replacements in one year is way, way outside the norm. I don’t know what would cause that many to fail. Maybe there’s something wrong with your power supply. (Just guessing; I’m not an expert about this). Or maybe you bought them all at once and it was a defective or damaged batch. Dunno.
It is not my “power supply”. I know about electronics. It is crappy design of AC to DC power supply. They run hot from the beginning. So forget the “savings” promised. ChiCom bulbs. I bought most of them at HEB. I’ve since stopped buying them there.
