It is still possible to buy incandescent bulbs in any wattage if you know where to look and what to search on. See https://permies.com/t/31062/incandescent-light-bulb#594263

I'm surprised that no one mentioned that even though incandescent light bulbs are supposedly banned, you can easily still buy them online IF you know what to search on: 100 watt incandescent A19
There is something to it.  Cutting edge research on some of it.

Take winter walks. Human bodies can adapt a little, so experiencing winter can help you be comfortable with less heat

already mention the bulb's voltage rating esp. with regards to long-life bulbs.  IIRC they mostly just make the wire filament thicker, which makes it less efficient in lumens / watt, but does make it last
, you will feel so much better with high CRI bulbs (otherwise "daylight" isn't so "daylight").  High-CRI bulbs are 10-20x more expensive than no-CRI bulbs (last time I bought 4 CFLs for $50

It is a complete LAMP.
But if you have a light bulb, the same electronics + LED's must be crammed in a smaller space -> a lot higher temperatures.

fine, however you also need to take into account what else changes as you vary the voltage. Lower voltages will produce warmer light; your 6500K bulb is not producing that color mix light when you run
Haven't read the whole thing but I appreciate your doing the math, Paul.

Further related note. I have SADD so went to 6500k CFL's and am starting to replace with LED (not 'corn bulb' ) lighting to reduce energy use. I do have issues with staying up far too late so

Most standard light fixtures are meant to take no more than a 60 watt bulb. Some wall sconces, bathroom lights and lamps are only rated for 40 watt.

I have found it to be very useful to right the date on the base of the bulb (any kind) when I install it.

Then I have a much better feel for how long things last.
