In the fall my buddy and I do lots of night riding on the trails in the foothills and mountains above Provo. This light works in a pinch by itself as a helmet mounted light but it truly shines when I pair it with an Urban 350 for a bar light. The beam is very bright with a long throw and a good spread. I have never seen a light as bright-white as this. Battery life is sufficient for a two to three hour ride especially if you use the mid-power setting for the climbs and reserve the full power for bombing the descents.
