Cygolite Pace 400 at Perfomance Bike
I've used the Pace 150 for the last couple years, riding occasionally in the evenings, and at night. In a low light or dark setting, on the high setting, I can see well enough to ride 10-15 mph on decent pavement with confidence, but a little more illumination would be nice. I figure this light is two and a half times brighter than the 150.
