The thing I like most about LEDs isn't the reduced energy usage or longer life, though those are super nice. My favorite part is now that they're running cool enough we can add some brains to the light bulbs. Motion sensors, timers, color changing add a lot of convenience and you get it in the same form factor you're used to.
Ideally our LEDs should emit a safe dose of UV-B and infrared too, because they are vital for vit D and melatonin production, both of which are extremely important for general health. As more and more of us become basement dwellers and winter depression enjoyers, this would help out a lot with public health.
That’s not true. We’ve evolved while being irradiated by the sun for literally billions of years. Your body has mechanisms to repair damaged DNA and kill+replace cells that are too damaged. Issues arise when the damage grows fast enough for your body to keep up repairs. E.g. you get a sun burn because you don’t have an adequate tan or you hug a reactor meltdown.
Supplements are an inadequate solution for many reasons.
Vit D supplements barely get absorbed by the stommach. The only way to get adequate vitamin D levels with supplements is to take huge doses for like a month while testing your blood to see if levels are adequate.
Most available Vit D supplements take a week to be metabolized into the active form.
Vit D supplements can give you an overdose of Vitamin D and have severe negative health consequences.
Meanwhile half an hour of sunlight gives you healthy levels of Vit D without risk of overdose.
I’m not advocating for 1000W/m^2 UVB radiation blasting you 24/7, I’m talking about levels that are low enough that you can constantly be exposed to without a increase in risk.
And btw a lack of vitamin D causes severely bad health outcomes, even if it would cause a minor increase in skin cancer (which it doesn’t), the benefits of adequate vitamin D levels would vastly outweigh that risk.
Same with melatonin, supplements can’t replace the effect of exposure to infrared light. But at least with infrared people won’t spread misinformation about how there’s no safe levels.

We evolved for lots of things that are harmful overall. Unless there is evidence that sun exposure gives some non vitamin d advantage the fact it literally causes cancer means you should avoid it in general.
I like how your rebuttals both say that supplements are both not able to give you vitamin D but also simultaneously a risk of overdose.
Avoid the cancer causing radiation. Just take a pill every day and get your blood work done to see how much you should take.
But at least with infrared people won’t spread misinformation about how there’s no safe levels.
That's because infrared light doesn't cause cancer. Although your support for infrared light exposure does identify you as a bit of a quack.
