My DiNotte 1200+ and my old 600L both had floody beams. They also shared a common issue: in lower temperatures, they would signal "LOW BATTERY" quite early. The 1200+ is currently doing this after about 35 minutes when running at full power at 25°F. So if you're a cold-temperature rider, expect it to give you the what-for much sooner than full rated runtime, if you use it at full power.

BTW yes, I discussed this at length with DiNotte.
