I don’t have many answers, but a couple more things to think about:
The fixture needs to handle the increased heat and wattage.
If you’re using something built in, the switch also needs to handle increased wattage.
Most of the above are probably not designed to handle “dimming” to control the heat.
Electric blankets might be a good starting place
Also, LEDs are generally about efficient production of light with less heat waste; I don’t think it’s likely to meet your needs.
I think it’s a cool idea, please let us know if you’re successful!
I didn’t get it at first, but good joke, close enough to whole ass.
