There's a mostly-unsubstantiated-by-data belief that LED lighting can cause health problems by some combination of flickering and narrow color spectrum.

  Do you have evidence that this rock doesn't keep tigers away?

I guess you know better than the scientist studying it: https://www.sciencedirect.com/science/article/pii/S0048969724072164 https://www.sciencedirect.com/science/article/pii/S004896972...

  Looks to me that _you_ conclude it's related to LED, I couldn't find that stated in the abstract, it might just be related to a general increase of artificial lightening, regardless of the source.

  Where does this article mention LED lights vs other types of artificial light-at-night? What I could find regarding light color: > However, most studies relied on satellite-images with a very low resolution (1 to 5 km, from the Defense Meteorological Program [DMSP]) and without information on color of light > noted that data quality suffered from many limitations due to the types of satellite images used and the focus in the vast majority on visual light levels only rather than considering the circadian-relevant blue light component, among others. Future studies should consider improved satellite-based ALAN technologies with improved resolution and information on spectral bands and apply these technologies to a variety of cancer sites to yield better estimates for the potential risks between ALAN and cancer. So nothing conclusive about LED being bad for your health (vs other types of light).

    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?

      Maybe it causes eyestrain. It's unlikely to cause cancer. It reduces energy use, which reduces smog, which reduces cancer.

      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?

    It assumes basic knowledge of the spectrum of various light sources. All white LEDs have a spike in the blue spectrum that incandescents don't: https://www.researchgate.net/figure/Spectrum-of-a-white-LED-clearly-showing-blue-light-which-is-directly-emitted-by-the_fig2_200071029 https://www.researchgate.net/figure/Spectrum-of-a-white-LED-...

  Per your link: >The primary meta-analysis of indoor ALAN and breast cancer risk suggested an association, but it was not statistically significant. That said, I'm actually sympathetic to the idea, and personally use incandescent lights. I just don't have any hard evidence to back it up (yet).
