They come from Home Depot, just like yours.
Then what you’re screwing them into is busted, and a fire hazard, and you should replace it.
Of course even at Home Depot there’s the cheap crap and the good stuff. And honestly, I often don’t even do Home Depot cause even their good stuff ain’t all that. When I bought ceiling fans last year I went to the lighting store, cost way more than Home Depot, but I know they will run silently and perfectly for years. Which no Home Depot fan I’ve gotten has ever done. Oh and they have sealed lighting kits with LEDs in em too. Really, if your LEDs are dying that’s on you. You got crappy stuff.
