There are no white LEDs. Just blue LEDs with coatings that convert a fraction of blue/violet light into lower energy colours. They work the same way that fluorescent light do. This means that LEDs produce a much higher amount of blue light that incandescents: 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-... Blue/violet light is known to cause cancer for a century now: https://www.nature.com/articles/s41416-020-01231-7 https://www.nature.com/articles/s41416-020-01231-7
