I opted for the lamp, because I go often by totally unlit areas. Compared with a B & M lamp with 25 lux of brightness gain is significant. The roads are much easier to see and also the distance that can be lit contributes that you feel safer in the dark. Only the "hole between bicycle light cone is a bit disturbing, but there is also a variant of the lamp with close-range illumination, but" only "40 Lux offers. The daytime running lights is super light and because the sensor and automatic switchover, I leave it to always.
