LED is bad?
- mrob 10y agoLEDs often emit more blue spectrum light than older technologies, which makes them more effective at stopping melatonin production. See: https://en.wikipedia.org/wiki/Intrinsically_photosensitive_retinal_ganglion_cells https://en.wikipedia.org/wiki/Intrinsically_photosensitive_r... LEDs also switch much faster than older lights, which means people can pulse-width modulate them, causing annoying flicker for people who're sensitive to it. Admittedly both these problems are avoidable, but in practice they're seen as LED problems because they're so common with LEDs.
