Interesting 270

It really shines though. I use it for walks starting or returning to the night and it really illuminates the road well.
I further refines the position a little and it will be perfect: I tend to put too low, as a "normal" lamp while it is far better to light (20m?), Without dazzling provided those coming in front.

Obviously (?), Autonomy is not up to the manufacturer claims. Eco mode is usually enough to me (even on a moonless night on a road without lights) but the lamp is up about 3h30-4h ...
And then it gets complicated because the battery compartment opens with a small Allen key (supplied) but so small I do not want to lug it in my panniers (a little mess) .
