I have the existing LED lamp replaced at my old touring bike, simply because it was not bright enough. It has always annoyed me when I overtake other cyclists at night and I could see the light of which already significantly brighter than my light. And now that's just so much that I even at night in the dark (really dark !!) Park may well recognize in advance already, where I actually go along (and because I like to travel fast, bright light is simply safer). I operate the way to a hub dynamo SON. Strong buy recommendation !!
