however, only 9–11% of the light from a 10 W emitter penetrated that thickness of skin.
Yes. The study discusses this. Its why the researchers moved to more powerful sources. To provide the results you refuse to read. Which I explicitly pointed out in my reply so you didn't have to worry about struggling with reading comprehension yourself. Which you ignored because it doesn't fit your narrative.
it does not matter how long an LED is shone on a human head
Yes, that is what the researchers said. LEDs don't have enough power; they measured that. That's why they didn't use regular LEDs. And they measured that change. And gave you the parameters of their setup for you to check (well, not you...for people into facts and science and such). And cited the people who had similar results. And cited people who had different results. And other science things that people who actually read this stuff for comprehension appreciate. That you ignore.
The energy delivered to the skin surface is different from the energy that penetrates to the depth of the target tissue
Different...energy? Physics would like a word with you. But physics does expect you to have done your homework, so I'll let it know you won't be around any time soon. I told it to be nice, and remember not everyone has a high school level understanding of physics, and they might say silly things. Be excellent to each other and all that.
often several cm below the surface.
Yeah. How about 3cm? Like the researchers said. In their measurements. That they didn't guess at.
the skull is a formidable barrier to light penetration, as well
Yes. The researchers discuss skulls in detail. Not just people skulls...sheep skulls and mice skulls too. 3cm on people; all the way through in mice. Sheep somewhere between. And a lot about hands, but I don't figure you care about those. They wrote it down and it got published. After actually doing the science.
This is all moot however, as NIR is not light
There it is! Ding ding! The audience watching at home knew this was coming.
If it was 'moot', you would have said "Acksually, infrared ain't light so STFU. Duh!" a couple of exchanges back and moved on to easier targets with less annoying 'facts' and 'proof' and 'published works of science by experts' around for anyone who cared to check. I guess even the most seasoned troll gets to a point where their own contrived protests become too silly to keep up with a straight face, and the lazy out is to not just move the goalposts, it's to move them to a different stadium.
Go forth and declare your victory, brave internet warrior. You have outlasted my ability to whip between WTF and LOL and Kagi is telling me "dude, you can't out-research aggressive ignorance". Besides, there's a hockey game on and my wife made cocktails.

I did mention this in my first reply, I don't know why you feel the need for this manic response.

I don't understand where these insults are coming from. It doesn't seem like you're addressing that lower frequency EM that no animal can see isn't light. Saying "WTF and LOL" and trying to be patronizing doesn't confront what I posted.
You realize for most of your post you are replying to your own source right? I didn't write that, I took it from your link and put the most relevant stuff in italics. When you are quoting "Simply put" and replying: "The siren cry of ignorance everywhere." that's from your link, not me.
The siren cry of ignorance everywhere.
