Some beamshots in a real usage environment: On a forest trail.
All photos are 50mm, 2.0s, f/4.0, ISO200, WB:5000K. Distance to the tree in the middle: 50m
Exposure was adjusted to match "what I saw" with high modes => Low modes are dimmer than in reality (dynamic range of my camera is not as good as dynamic range of my eyes, sorry.. 
)
