“They can’t be used in closed fixtures.”
Says who? And why?
I’ve been using a 100W-equivalent one in a closed fixture - no problems yet. I’ve got two in a closed fixture with along with a 60W incandescant - again, no problems. I’ve also got them outdoors, hanging downwards (supposedly a no-no) where they work fine (but take a little while to warm up) in temperatures well below freezing.

I walked around, and between my fan/ceiling lights, the can lights in the kitchen, and the enclosed light fixture in my laundry room, all of those locations are either hanging down bulbs, or enclosed.
The outside light- which are security lights on movement also hang upside down, and the entrance lights to house and garage are also upside down. Basically the only place a buld doesn’t hang upside down is over the stove.
I have also been told they won’t work inside a refrigerator, nor inside your oven.
The mandatory part of this whole discussion is abhorant to me on the face of it.
I use them in my house and I have one fixture that’s closed. The bulbs in that fixture don’t last anywhere near as long as the open fixtures.
