My Niner full suspension bike has glow-in-the-dark paint. It isn’t quite that bright unless you charge it up with a black light first. If you just take it from a normally lit room to outside, it glows noticeably for about 30-45 minutes. If you really charge it up a bit, it’ll glow more and last for as much as an hour before it starts to fade. I was pleasantly surprised when I took it out for a rare night ride last fall that it still glows nicely after owning it for many years.
