As requested, here's the beam from the Arc LE and the LS compared together with various battery configurations - I wasn't able to take a picture of the Arc LE at 2 meters like the LS because you can barely see the beam and it's spread out too big for the picture. Also note the camera was at a slight angle to the celing in the LS pictures. It's a large 150kb picture with minimal compression so you can see the detail.
