No matter how much I think about it, I feel like LED lights are bad for the eyes

The ceiling LED light was getting dim, so I replaced it this time.
But the brightness is insanely bright, so I'm quite taken aback.
As a temporary measure, I've laid some scratch paper over it like a cover, and that makes it a bit better.
It won't overheat and cause a fire, will it?
They say LEDs have a long lifespan and are economical,
but I've been using them for a long time, and honestly, setting aside the cost-effectiveness, I'm not sure if they are actually good.
I heard there are lights that allow you to adjust brightness and color temperature if you pay a bit more; should I have bought one of those?
