I use a MiNewt 200 ("only" 200 lumens) and a couple of Planet Bike "Super Flash" blinkies on the rear. Although this particular MiNewt is well down the ladder on power compared to the other NiteRider offerings, it is still bright enough to get comments from pedestrians, but not so bright that it's blinding motorists or fellow bicyclists. I guess it's a good compromise. It sure lights up the road for the daily commute
