You're playing so defensive (for LEDs) wonder why - just to argue? If one uses the same logic - does anybody states that LED are GOOD for the health? What the lack of such statements means - they're bad, or have no effect? At the end - is it your business at all if I want to use incandescent lights, or CFLs, because I find them more suitable for my personal needs in MY home?
No I just refute a claim on which the provided source does not prove or indicate in any way. I'm not arguing LED to be better or worse, I'm just looking at a proof of some kind to what is argued.
But it seems like it's too much to ask? I should just accept whatever comments I read without any critical thinking?
Maybe it causes eyestrain. It's unlikely to cause cancer. It reduces energy use, which reduces smog, which reduces cancer.
