The Exposure Six Pack 15 stands as a pinnacle of mountain bike lighting technology, combining immense power with smart features in a single, robust unit. Its 6,000-lumen output from six LEDs provides an exceptional blend of central throw and peripheral illumination, bathing technical trails in light. The standout feature is the Reflex 2.0 system, which uses onboard sensors to intelligently dim the light during climbs or slow sections and boost it to full power on descents, effectively extending battery life without rider intervention. The integrated 20,000 mAh battery is among the largest in its class, offering substantial runtimes, and the move to USB-C allows for faster charging and the ability to use the light as a power bank.
The new OSD+ color screen is a significant upgrade, clearly showing exactly how many minutes of runtime remain at the current setting. Build quality is premium, with a machined aluminum body rated IP67 for complete dust and water resistance. While the mount is secure once installed, its initial setup is less straightforward than strap-based systems, and the non-captive screw is a minor oversight. For riders seeking a do-it-all light that eliminates the need for a separate helmet lamp on most terrain, the Six Pack 15 delivers unparalleled performance and technological sophistication.
