Bike lights in the dark

The internet says that they made low beam bike lights sometimes (maybe from germany). Any experience having a bike light which is bright enough to cycle on completely unlit roads/paths without having to slow down a lot, without dazzling oncomers? Is any decent bike light likely to do it or do I need to look for something specific?

I've slowly expanded my comfort zone cycling, but it would open more options if I could reliably cycle on dark ways. I used to have a decent light but it was a bit of a trade-off between "being able to see far enough" and "not dazzling people", and now I have a cheap light that's suffices for urban cycling but doesn't light things up much.

I might have asked this before, I can't remember.

When I put it like that, it sounds like I was pretty productive! But it's hard to persuade my brain until (maybe) enough areas of my life start feeling like they're under control that it starts to slowly get my brain used to the idea that I might be adulting ok even if I haven't done something incredibly useful in the last few minutes :)
