If part of your ride is through a park trail at night you'll need about 250 lumen wide beam.
My peeve with modern electrics is that all the controls is with one button. On the road, I forget how many times I have to push to get the setting I want. Sometimes I don't even find it as the ambient light sensor automatically overrides what I want.
All I really need are:
on/off
low (for urban neighbourhood)
low flashing
high wide beam (for unlit park trails)
