Whether it's a 24-hour race or a week of winter commuting, Blackburn's System X6 has the power, versatility and reliability to get you where you want to go. Thanks to the dual-head Luxeon III lights, you have both a wide angle and narrow beam light for the ultimate in illumination. Plus, with the remote switch, you can adjust the lights from 30 to 70 to 100% power to use only the amount of light you need, which saves battery power. And, the System X6 won't overheat or fade with time thanks to Blackburn's constant-current technology, while the frame-mount NiMH battery is reliable and powerful. The lights feature easy-to-use quick-release mounts, too.
