No personal criticism intended BarracksSi. I agree those would be suitable for anyone just using bicycle paths and cycling in good weather. Unfortunately I have to mix things up with heavy downtown traffic late at night several times a week and need something a lot more conspicious to catch motorists attention. And the effectiveness of any light is severely compromised in heavy rain where wet pavement sucks up lumens like a hungry cat so I currently run two 900 lumen lights with the option to light up another four. The reason I'm still stuck with batteries is that I havent found a generator that will handle that kind of load (thats just the front) and because I'm running a 12V system for effeciency.
