LED lights have nothing to do with human wellness. They are just a more efficient source of light. PWM dimming or spectral differences aren't harming anyone.

Well there is recent research around a 'blue spike' in most LEDs. "nothing to do with human wellness" might be putting it too strongly. See Prof. Glen Jeffery and his work in this area. Note however that this is nowhere near a settled science yet.
