What if we had programmable LED bulbs that extended into the infrared, and the amount of infrared was inversely proportional to the weather?

In the winter, most electronics in the house are 100% efficient, because they heat the house. The only things better are heat pumps and insulation.

One of the advantages of LEDs is not needing to swap them out so often, so while I could swap bulbs in the winter, I really won’t, and neither will most of us.

Bright sunlight is 1 kW per square meter. You're going to need a lot of LED light to compare.

Which means the IR light from the old bulbs was pretty much neglectable too.

That is the biggest variable, I don’t know how much power is needed to make a difference. They did experiments with mices but I didn’t do any calculation of the power needed. Best thing to do it to go more outside, but that is not the current trend.

I'm very confident that we'll find the effect works well without standing out in the noonday sun. Moderately confident that we will discover that certain wavelengths are more important than others. If you find the right emitter, you might be looking at 40W on the winter solstice, and less than half that at the equinox.

Make sense. For therapy they often use infrared LED.

I use the heat dish as a quick test that was locally available and to my surprise it worked!
