Beam Comparison - Headlamp

Beam Distance Comparison - Click on the images to compare at full size. Keep in mind that beam photos like these may overstate the negatives of dimmer headlamps, since unlike the camera (which is kept at the same settings for all photos), your eyes will adjust to dimmer light and thus see better than is implied by the photos.
