Where you are riding is really important when it comes to lights to recommend.
If you are in a well lit area then your primary concern is to have a light bright enough to be seen, which might only be around 150 lumens.
If your ride home doesn't have much for street lighting then you need much brighter so you can see the roads ahead, and I'd be looking for more like 700 lumens.
And if your ride includes any sort of rough dirt roads or even single track then you really want some high power lighting.
