Why use so many words when few do the trick. NIR has been known to be useful for a while. Closer to 1000nm, penetrates deeper, but isn't as 'potent' 670nm is great, but you can notice it when it's on, ESPECIALLY if it's the only light in your room, which can be annoying. It's true that NIR stuff is healthy for your eyes, but HOW much so, is up to debate. I've bought 10 30 W NIR bulbs to no effect (range from 650nm-950nm), but on the other hand blue light bulbs have been helpful with increasing visual accuity (shorter wavelengths appear to your eyes as fuzzy, so your eyes push themselves to refocus more often, though at the downside of low dopamine levels and no will to do anything {maybe this goes away with time? But I've spent a few days doing nothing due to blue light and I like to be productive}, while red light has no effect on motivation, but worsens my eyesight (light appears in focus, no need to refocus, eyes get "lazy") All of this anecdotal, but I really do like reading/learning about this stuff and NIR seems to be more fad than not in real world situations
