Hi Pete!
That's a nice-looking light, for sure, and very powerful. Looking closely at the design, it doesn't appear it would have a horizontal cutoff to the beam.
It would be ideal for use on trails, where one could easily see overhanging branches, but I'd be a little concerned about using it on the road for fear it could blind oncoming drivers.
I guess the appropriateness depends on primary usage. It seems to have a generous standlight time at around 10 minutes or so.
The dynohub looks real interesting; it appears to be a Shutter Precision model.
Best,
Dan.
