I used to switch to incandescent desk lamps in the winter (and back to LED in the summer) to help keep my hands warm on the keyboard.  Then Congress unconstitutionally outlawed manufacture of incandescent bulbs and washing machines around 2010.   (Only "High Efficiency" washers are allowed, which makes sense in water scarce places like SoCal or AZ, but for people by rivers just means your clothes don't get clean.  Yes, I've developed workarounds.)   

For a while, a German company offered "indoor electric space heaters" that screw into a light socket and emit visible light as a by product.  I loved these, but either not enough customers got the joke, or govt types didn't think it was funny.  I haven't seen any replacements.   I've tried laying a scarf over my hands, but although I can touch type, my fingers would get misaligned reaching for function keys, PgUp, arrow keys, mouse, etc.  (Not a problem with vi/vim.  Which is why vim is still my editor of choice.) 

 Just had a look on Temu, because savvy Chinese MUST still be selling incandescent globes on the grey market, right? Not really... (!)

All the "Edison" globes are LED not incandescent tungsten filament.

There's some E14 "household oven" bulbs with what looks like real tungsten filament (makes sense, led can't take the heat).

And reptile heat lamps, with visible-light blocking glass.

And that's it... Can't have consumers making their own choices... 

 it seems that true incandescent light bulbs are becoming increasingly rare and difficult to find due to the widespread switch to led bulbs for their energy efficiency and cost savings
