Some of the compliant stvzo lights have surprisingly very wide beams. There are reviews on blogs making comparisons.
I had a Breezer commuter with dynamo-driven B&M lights with a proper cutoff, and loved it. I wish the American makers would adopt this standard.
My rechargable helmet-mounted L&M Vis Pro runs 600 lumens at full power, with a front white pulsing mode at 150 lumens. The rear red pulses at 25 lumens. I run the pulse mode in the city at all hours and it is plenty bright day and night. When I'm on the bikeway at night I run steady at 150 or 300 lumens (depending on conditions) to avoid blinding other bikers, and turn my head away when passing
The boys on this thread who are bragging 1000 lumens must be riding on the Autostrada or remote roads - I sure hope I don't come across them.
