Bike light database doesn't seem to list any alternatives. It looks like L&M has replaced the $100 Vis 360 version with the plus version for $180. That's a pretty stiff price hike. I had a fellow retired medical doctor rider for whom price is not much of a consideration. The Vis 360 was a pretty good product but more than I was willing to pay compared to just putting more than one inexpensive rechargeable light on my recumbent trike. You are right that the original is not available even as NOS online.
