i went down a rabbit hole doing max permissible exposure calcs for the light you linked and basically i personally wouldn't worry about it. the energy is low and distributed among many emitters. by the time you're far enough away from the light to focus on it, you're receiving max a couple hundred microwatts/cm^2 at the cornea from each led.

I don't know if you ever write blog posts or anything like that, but I would love to see explanations about how you made those estimations. I honestly wouldn't know how to even start :-).
