Here is a short video shot on my Gopro 3+ of my B&M Lumotec IQ2 U showing the difference between high and low beam.
The apparent lack of breadth in the video is down to the camera sitting on a stem cap mount which brings the shifters and my hands into shot.
You can see how the light is powerful enough to pick up the detail in the grass verge.
