The Fenix HP16R Headlamp is the perfect tool for those who require high performance and long runtimes. Powered by its included 3000mAh li-polymer battery, this headlamp can blast a combined 1250 lumens from its spotlight. It can shine that light for up to 300 hours on its lowest floodlight brightness level, or even longer if you carry along extra AA batteries. A neutral white LED floodlight produces a warm light for better color rendering. 60° tilt mechanism allows you to place light where you need it and the lock out function helps avoid accidental activation. For all night exploring or on the job demands, the Fenix HP16R Headlamp won’t let you down.

    Excellent headlamp with well rounded features for beam widths and brightness levels. My only concerns are the wires from front to back over time and tight quarters and the weight of the battery pack. Durability, fit and finish are as expected from Fenix; none better. Fenix is similar to Filson (for those of you that know quality brands) YOU MAY AS WELL HAVE THE BEST.

    Fenix gave me a discount on this new headlamp to replace my 8 year old prior Fenix model, which I dropped and broke (the plastic fitting that holds the light). If they had the parts, they would have repaired it for just the price of parts! This new headlamp is fabulous! I’m using the flood light function frequently – my old model did not have this feature. Fenix keeps getting better and better!

      Hi Graham. I talked to warranty and they said they sent you the return authorization for that on Dec 8 and they are waiting to get the light from you. They will send you the RA again in the event you missed it.
