When Knog announced that it was going to create a new modular light system, we were pretty excited, and seeing it hit the streets has us even more giddy. Combining Knog PWR Banks with the Knog PWR Lighthead gives you the option to swap different light heads and power reservoirs as needed to create the perfect combination of light and power for any ride. The PWR Lighthead comes in three different sizes, from the 600-lumen Road, to the XL 1850-lumen Trail, allowing you to determine just how much light you need without purchasing entire sets of extra lights. Each light head is compatible with any of the Knog PWR Banks to power up. Pick a smaller PWR Bank for shorter rides with lower lumen heads, or a beefier bank for after dark MTB adventures with the 1850-lumen head.
