I gave miles, not time. Time would depend on how fast I ride.
Honestly, there is some percentage of that that is group rides where I didn't have it on....and I use Energizer Lithium Advance or Ultimate batteries...
Low duty cycle flashes can be just as bright as high duty flashes but consume proportionately less power. Also the beam width/pattern will trade off width for brightness. Anyway, IMO, the Swerve isn't the brightest, but it's better than the Planet Bike Superflash, and much better than the NiteRider Cherrybomb. I use it in daylight.
