ascherer B&M dynamo lights aren't amazingly bright. German law doesn't (or didn't) allow more than 3 watts which is boneheaded. So they engineered the heck out of the optics. If you aim it right, it's useful but never impressively bright. Make sure the top edge of the beam is horizontal. You can do this by putting the bike alongside a wall, but what I do is notice how high the beam is on a nearby object. I want it to be the same height as the light itself, maybe a tiny bit lighter so I can light up people's necks but not their faces. The cheapo Xanes light is probably brighter than your light.
