Charging the HM50R Rechargeable Headlamp

Uncover the anti-dust cap and plug the Micro USB terminal of the charging cable into the charging port of the headlamp. Once you’re done recharging this headlamp, be sure to remove the charging cable and replace the anti-dust cap. The max charging current is 700mA, and the charging time is about 1.5 hours. The indicator displays blue when charging, and turns green when fully charged. The headlamp can only be used on Med output when charging.

Warning: Avoid charging non-rechargeable batteries.

Intelligent Overheat Protection

The light will accumulate a lot of heat when used on Turbo output level for extended periods. When the light reaches a temperature of 65°C or above, the light will automatically downshift to High output to reduce temperature. Reset to Turbo if needed.

Low Voltage Downshift

When the voltage of the 16340 battery in use drops lower than 3.0V, the low voltage downshift function will be activated. In this state the headlamp cannot be used on Turbo output and will only cycle through High, Med and Low.

Extended Runtime

The headlamp will automatically step down by a few lumens after being used for an extended period on any of the High, Med or Low outputs, to extend runtime and to guarantee illumination outdoors.

Use the HM50R as a Flashlight

Remove the tail cap and the battery, then remove the headlamp from the holder. Re-insert the battery and screw back the tail cap.

Battery Replacement

Unscrew the tail cap to insert the battery with the anode side (+) towards the lamp head, then screw the tail cap back on.

Headlamp Holder Replacement

The headlamp holder is made of enhanced silicone, which gives it good anti-tearing ability and mechanical strength, and makes it resistant to low and high temperature, ultraviolet rays, acid and alkali corrosion. The material feels smooth to the touch and should not cause allergic reactions.

If the headlamp holder needs replacing, open the tail cap, remove the battery and the holder, and replace with the new spare holder.

Headband Assembly

Notice: The headband is factory assembled by default.

Usage and Maintenance of the HM50R

  • Disassembling the sealed head can cause damage to the lamp and will void the warranty.
  • Fenix recommends the use of only excellent quality batteries in the HM50R.
  • If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage or battery explosion.
  • Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the lamp’s performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:
    A: The battery needs replacing.
    Solution: Replace battery (Ensure battery is inserted according to the manufacturer’s specifications).
    B: The threads, PCB board contact or other contacts are dirty.
    Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don’t work, please contact your authorized distributor.

Warning

The HM50R headlamp is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the headlamp directly into anyone’s eyes.

    Really like the lamp. The different brightness settings are great. The only thing I don’t like is that it needs to be charged frequently.

    I had one for three years. Loved everything about it other than the micro usb slowly got worse until it broke and the light no longer came on. just ordered another one along with a charging cradle, ill just take the battery out to charge. wish they would use the old nokia style round charging port.

    Very light, well built, and very, very bright with simple controls. A must for my backpack. Only thing missing is a strobe feature, else perfect.

    This is a great, reliable light. Designed for extreme conditions like mountaineering or long-term backpacking. However, I don’t understand how this ‘last-resort’ light is missing the signaling functions, for example, one short flash every 5 seconds, or sos. You don’t need those functions on ‘base camp’ lights like TK35UE. But you definitely need it on this one, because just in case!

    Would give a 5, but the flashlight auto dims after a short time on high.

    I am using HM50R almost everyday. I carry it all the time when I am at work because the working environment is not bright enough and I need both hands to work. It is great EDC headlamp for me.
    But I like the HL50 head bend clip. It can remove the lamp easily and you can redirect the light direction easily.
    I like HM50R turn on but not HL50. HL50 can turn on easily in your pocket and loose battery charge.
    I like HL50 battery choice.
    I also like LD15R’s light function. If the LD15R clip be removable then that will be very good.
    The USB charging port seems has a big gap. You can see the light coming out if the rubber plug is off. I crazy glue the rubber so there is no chance for water leak to ruin the light.
    We need all the good functions together and not separate to all 3 different models as we can not carry 3 lights.
    Currently I have all 3 and really hate those functions can not combined to one. I use the HL50 head bend and HM50R flashlight. I have LD15R but because of the permanent clip so I couldn’t use it on the head bend.
    Also the battery selection. I would suggest CR123,16340, or LIFePO4. should all be able to use and of course the adapter.

    I bought this specifically for running at night as it is very minimalistic and lightweight. I have been very satisfied with its performance. I usually run it at setting 3 which is just over a hundred lumens. This lasts over a week with my running schedule. This allows me to see all the ground about 20 feet in front of me to prevent myself from running into holes etc while not being too bright towards oncoming vehicles if I am running on a sidewalk. If I need it brighter the push of one button bumps it up to 500 lumens. I also run with a pd35 tac and use that if I want 1000 lumens to light up and Id something. My only complaint is that the beam is so wide that it slightly reflects off the top frame of my glasses no matter how high I mount the headlamp and even rotating the beam up some, granted the frames are a polished silver color so if they were a matte color maybe I would have different results. I dont ever have this issue with the hr60 but it bounces around too much and is front heavy for running.

    Love this little light. Keep it in the console of my truck for emergencies. It, being a headlamp and hands free, has replaced the regular flashlight I kept there.
