Don't let the lack of daylight throw off your training schedule, get the Black Diamond Sprinter 500 Headlamp and blaze away. This baby throws out an amazingly bright 500 lumens at full throttle, more than enough to navigate even the burliest trail safely in the dark. With a full range of strobe and brightness options at your disposal, a flashing red rear LED to ward off the MTB'ers, and several strap configuration options, the Sprinter 500 is the trailrunner's headlamp to end all headlamp discussions.
