All settings use the same beam pattern. There is no difference in the beam shape, only intensity of the light. It checks for bird's nests in the trees and I can see rabbits on the side of the road.

There are several programmable modes. Program1 runs full power with 3 hour burn time on high, 10 hours burn on medium and 24 on low. Burn time is inversely proportional to the intensity of the light and so the low/24 hour setting isn't very bright at all. There is another program mode which does 4/12/36 hours respectively and the 36 hour setting is dim.

I am using Program3 which skips the low setting and does 3 hour full brightness and 10 hours at medium. Motorists don't flash their high beams at the medium setting. I change to the medium setting most of the time when cars approach from the opposite direction.

The GoPro mount allows the light to be tilted up or down but at full brightness it is splitting hairs. It is really intense. This light would be totally illegal in Germany where they require a specific beam pattern cut off at the top.
