The HM50R from Fenix is a compact rechargeable headlamp which is designed for use in the cold outdoor environment of rock and mountain climbing and long distance hiking. The headlamp can also be detached from the headband and be use as a handy mini flashlight. The HM50R measures 67.5mm long and 33mm wide. The headlamp weighs 63 grams without the battery installed. The HM50R is constructed from an aircraft-grade aluminum alloy which features a Type III hard anodized, anti-abrasive finish. The headlamp is held in place by a detachable silicone lamp holder. The headlamp and holder is fitted to a sweat-channeling, reflective headband.
The Fenix HM50R utilizes a Cree XM-L2 U2 white LED, a smooth reflector and an ultra-clear glass lens with anti-reflective coating. The headlamp can be powered by one rechargeable 16340 Li-ion battery or one CR123A Lithium battery. Reverse polarity protection guards against incorrect battery installation. The 16340 battery can be recharged inside the headlamp via a connection from the Micro-USB port in the light to an external USB power supply. A charging indicator above the LED turns blue when charging and green when fully charged.
The HM50R produces a maximum output of 500 lumens , a beam throw distance of 80 meters and four light modes: Turbo 500 Lumens 2Hr 30Min 16340 Battery – 2Hr CR123A Battery; High 130 Lumens 10Hr 16340 Battery – 14Hr CR123A Battery; Mid 30 Lumens 24Hr 16340 Battery – 48Hr CR123A Battery; Low 4 Lumens 90Hr 16340 Battery – 128Hr CR123A Battery. The headlamp automatically downshifts by a few lumens after being used for an extended period in Turbo, High or Mid to extend runtime.
The headlamp is operated by a side switch which controls the on/off operation and access to the various brightness levels. Press and hold the switch for 0.5 seconds to turn on/off the light. With the HM50R turned on click the switch to cycle through the light modes. The headlamp will turn on in the previously used brightness level. The Fenix HM50R headlamp package contains one ARB-L16-700 Lithium Ion battery, charging cable, O-ring, rubber anti-dust cover, silicone holder and user manual.
