Pretty impressed with the light.
On 10% power it's bright enough for streets and will last ages.
On 50% power you can safely ride off road in total darkness, basically about 6miles of my little 15mile loop is unlit and it's safe and fast at half power.
On 75-100% it's blindingly bright, basically no issues at all, done my 15 mile loop in 70 minutes, as I stopped for pics etc, so I'm no slower than in the daytime, 56-65 mins typically....well pleased and didn't have any cars pull out or cut me up on road sections and pedestrians moved when the light came up behind them!
