I have a GoLight, I purchased it about five years ago when I had a camp on the Trent River in the Kawartha Lakes. Returning to camp in the dark was dangerous because the river has lots of buoys. The first night I used it I came upon a guy fishing in the dark in a paddle boat with no navigation lights. About a month later I stumble upon a couple making out in the middle of the lake with the navigation lights turned off. This light is powerful, it would easily light up two buoys ahead of me. It operates remotely, turns nearly 360 degrees and moves up and down.
