The X-120R X-ACT FIT HEADLAMP™ is a powerful headlamp with a comfortable fit. This version is powered by a Li-ion battery pack with integrated micro USB input (or it can use 3 AAA batteries). The Comfortable X-ACT Fit™ system located on the side and back of the band provides a microadjustment for a custom fit. Unique, no “hard point” hinge design fits your head perfectly and allows the lamp to focus forward or down towards the ground. Settings include flood, spot, and red night vision modes. Dial provides transition between light modes and adjusts brightness continuously from 0 to 120 lumens.
