getting the right aim is tricky, our eyes adjust how much light it will accept.
you need to test it on a very dark place where your source of light is only from your ride. step away 10-25 meters and see if you think/believe you could able see objects behind your ride. if it irritates even just a bit, then it's not good enough.
been playing with adjusting headlamps myself, I thought they were ok. no incoming motorists beam me high on the city. but I realize on provincial dark roads. 70% of incoming motorist beam me high.
I was not able to get my aim right without the help of angry motorists that I glared on the dark provincial roads.
