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 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.

    So far great.
    Using it right now in the woods on a hiking trip. The Surefire CR123 that I’m using is lasting surprisingly long.
    The beam is great….nice spot.
    Reading in the tent with the low setting is perfect. The headband is very comfortable stays in place without having to make it tight. Also using the CL09 lantern tonight for the first time in the woods. I made a tripod lamp out of a couple of pieces of dead wood and we’re using it to light the area where we’re cooking. The high setting looks like a 100 w bulb in the middle of the woods. My wife loves how it lights up the whole tent.

    This light looks to have excellent build quality. Love that it is rechargeable AND can accept regular batteries. I plan to use this to summit Mt. Rainier this spring. Reliability is extremely important to me. I am trusting this light to serve me well on my journey!! I sought to find the very best to light my way in frigid and wet conditions.

    I’m new to Fenix products, but this seems to be made of high quality material. Not used in the field yet but worked great out of the package. Didn’t come with a wall plug, just the USB cord? The removable flashlight design is interesting, a strange option for a hands free light, but why not. Only comes with one rechargeable battery, Fenix should bump the price a few bucks and offer two batteries; waiting to charge is lame, and so is buying batteries:) All in all, I’m a happy camper! 4 stars Fenix;)

    It is good to have a rechargeable light, if it wasn’t I’d have had to purchase 3 batteries by now!
