As for the "damaging effects" of Led on body, it does not come from lighting but Handphones and computers.

Led has blue light emitted when your handphine display is white. This blue light mess up your brain sleep wake cycle. You can buy a screen to filter or turn on night mode.

For lighting to play safe us yellowish light not pur white. However, due to the distance vs a handphone put so near your eyes, the effects are negligible anyway .

Other negative effects likely nonsense fabricated. florescent bulb when they came out to replace incandescent bulbs also have many negative fabrications. Every new technology always have some people come out to fabricate nonsense
