It's the museum with The Night Watch (https://en.wikipedia.org/wiki/The_Night_Watch) which is a giant painting, but the two times I've been there it has been pretty well lit. And not in the basement. But yeah, it's an amazing museum.
My grandma who lives near Amsterdam always told me most people who live in Amsterdam know the museum more from the biking lane that goes through it then the art that is inside it. https://www.youtube.com/watch?v=fjgyL6aUOcc this is a video of the Rijksmuseum and the bike line through it.
