I remember some Hope ones coming out a while back that were a small cylinder with battery in back and LEDs in the front. Then I read about things like this , small self contained units that would be perfect for my business travel by bike - this one charges via USB.
I wondered what else would be good - small, self contained, not too expensive, and bright enough for canal towpaths, unlit roads and the like. Good runtime a plus, as is many different levels of brightness. Don't want to dazzle motorists unnecessarily.
