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.
