The main place you’ll still find them are as heating lamps (for things like terrariums)
I thought they used incandescent lights for those, and some (like the terrarium heaters) aren’t even incandescent, they’re just ceramic resistance heaters that fit into an E26 base (screw-in light fixture).
They definitely use incandescent globes for heating as well. I just remember when I had fish, the shops would advertise neon heat lamps for terrariums. (I think it might have had something to do with infrared heating, but I’ve never had a terrarium so I’m kinda guessing now.)
