The FL85R Headlamp is our most powerful rechargeable front loaded LED headlamp. The light features our Flex Charge Dual Power system. The Flex Charge feature allows for the rechargeable battery pack to be recharged inside or outside of the headlamp using a micro USB. The Dual Power allows for it to run on our custom rechargeable lithium battery pack or standard alkaline batteries. The first button on the headlamp gives you the ability to shine an ultra wide flood beam and then quickly twist the bezel to a long reaching spot beam with transition halo. The second button on the headlamp enables the user to switch quickly to a fixed red LED light to preserve night vision. It also includes a reflective safety strap for additional safety benefits.
