I have Sigma Aura 80 headlight, which has a cut-off beam so it does not blind oncoming traffic. No idea about the lumen output; it has the stated illumination of 80 lux, although I haven't been able to find at what distance it is supposed to do that. One source said the light output of it to be rather low, around 200 lm or thereabouts, but it projects all of it where it should go, and illuminates the road about as well as my other 700 lm light without a shaped beam that is better suited for offroad riding in the dark.
