Lights: How bright is actually practical?
I currently ride with a Cygolite Metro 700. I have not had a whole lot of night-riding lately, but I remember doing a few a couple months back and thinking the light was quite awesome and did a good job of illuminating my path at it's nominal 700 lumen output.
Cygolite (and others) make even higher lumen lights, however - upwards of some 1,100 lumen in the Cygolite Metro 1100 (and other unknown brands seem to claim even higher than that on theirs). Between these two are plenty to choose from as well.
Is there much point into brighter lights than my current 700? Especially in the Metro line, having as it does the same relatively narrow emitter facing. A wider spread at a higher lumen (to maintain or improve lux) is understandable but not all of them appear to be so.
