I just purchased both a L&M Urban 800 and a Vis 360 Plus helmet mount. Jenson USA price matched the lowest price I could find. I'm happy to answer any questions you might have.

Not sure what kind of pattern you are looking for but the beam on the Urban is very smooth from center to edge, no hot spots at all. I was skeptical of the side lights on the Urban but they are much more visible than I though they would be. The Vis 360 Plus has a noticeable hot spot in the center and is used to augment the bar mounted light - to flash a motorist approaching from a side street, look into a turn, etc.

Bike Light Database has beam shots. I'll see if I can take some pics tonight and post as well.

Here are a few pics.

Because of the shape of my helmet, he mount for both front and rear lights on the VIS 360 interfered with fit when mounted lower. I had to mount a bit higher as a result. All helmet mount lights are a compromise in terms of mounting and I now have a small strip of velcro securing the coiled cord so that it is a bit more discreet. The front light has a second mounting option that I haven't used yet and I'm starting to think that this might be better - still playing with it.








Swivel for potential stem mount. It also comes with helmet and gopro mounts.
