Finally, enough light to read by.
Um...
I’m sure resilient incandescent light bulbs will still be available just like they used to be.
Industry never stopped producing resilient incandescent light bulbs, and those are the types used in mines and other areas where a lot of shock waves produced.
Personally I need an incandescent light bulb in my pump house every winter and I go through two or three a year and they were always available and they always will be so I’m not worried about nothing.
I’ll raise pigs in my pump house before I do without my own well if that what it would take to keep the pump from freezing.
