You know, those funny looking things you bought by the dozens back in 2014 and stored away.
BTW, still available, but at a premium price.
Halogen incandescents are available all over the place.
I have a bunch and I've never used them. I hated CFLs so I expected to use my stash of incandescents. Once LEDs got cheap I used them and haven't looked back. The only incandescents I still use are specialized ones like refrigerator and oven, or ones in closets that I rarely use. And if the closet ones burn out I'll put in 60-watt equivalent LEDs.
One thing I even do is user overpowered LEDs. I'll put a 100-watt equivalent LED in a 60 watt fixture because it really uses 17 watts. I can light up my yard from my porch lights because of that.
