A new level of brightness has been added to the Fenix HL18RW. This upgraded model has a maximum output of 500 lumens of cool white light. The HL18RW has dual power sources that both can be charged via the micro USB port on the headlamp. The first power option is the 1300mAh Li-polymer battery pack that is included with purchase. You can also use three rechargeable AAA batteries as a secondary power source. Only weighing 2.8 ounces, the HL18RW is perfect for long hikes or trails because it is incredibly lightweight. Additional features include a battery level indicator, reflective headband, adjustable beam, and lockout function to prevent accidental activation. The HL18RW will also include a Micro USB charging cable and user manual, so you charge and use the headlamp right out of the box.
