Backyard Beam Pattern Photo: Compare all lights here.
We photographed the lights in the same location setting with the same camera settings. The photos were taken in the back yard that is approximately 25 yards long. These photos feature many objects and a distinct background to analyze detail and beam pattern.
Tunnel Beam Pattern Photo: Compare all lights here.
The location is useful since it has walls and a ceiling that can display a bike light beam pattern. The walls have a lot of graffiti on them and actually show detail when they are lit up by a light with a wide angle. Cones and targets are set up with the far target set up at 80 yards.
