You can see that's its basically worthless for increasing visibility of the road surface so Low at 50 lumens is basically invisible.
This is a photonic barrier. The camera or your eye is adjusted to the brightest level of light which is in this case the ambient level. Because of this, the lower light from the flashlight is effectively still in shadow, so even though it's hitting things on the other side of the ambient light it's still dimmer than what your eyes are adjusted to.
