Output selection for the HM50R:

With the headlamp switched on, single click the switch to cycle through Low→Med→High→Turbo. Note: The headlamp memorizes the last selected brightness. When turned on again the previously used brightness level will be recalled.

Battery level indication

With the headlamp switched off, single click the switch to display the battery level for 3 seconds in different colors:
  • Green constant on: more than 80%
  • Green flashes: 50% - 80%
  • Blue constant on: 20% - 50%

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.


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.

Best headlamp ever.

So yea I've had many headlamps and have used them daily at my job as a inspector.

But none compare to this simple little headlamp. The fact that there is no mechanical moving parts like hinges or adjustable lens I believe is what makes it so durable. It's just push the button and swivel it in its silicon holder and your good to go.

I've had my HM50R for atleast 3-4 years and have put it thru hell. I've used it almost ever day since I purchased it. Hell, I've used it so much I've changed the headbands 3 times because they have become so stretched and wore out. But the light just keeps on lighting the way. It's outlasted the original battery that came with it as well I did have to purchase two backup battery's for it but the amount of use I have got out of it.. I'd say I more than got my money's worth.

Best compact headlamp ever!

Bright and simple headlamp.

I have had the HM50r headlamp for around 2 years now and feel I can make a comfortable review of it's full potential. I love the minimal size with no useless gadgets or intrusive head straps. Plenty of brightness on high with a very workable and usable mid and low level. Light has been wet from rain with no issues whatsoever. Due to the comfortable headband you almost forget it is there......yet it stays put with only a single strap. A++

Nice lamp. Battery died too soon

The lamp is nice and compact and bright enough for most uses. Unfortunately the battery doesn’t last very long, even in cool climates. I’m on my 3rd battery now. The first two went dark after less than a year.
18650s are much more reliable.

Thomas Meixl

This headlamp is bright and light. Great reliability, and small size for running or camping.

David Nanney

This is the second Fenix head lamp I have purchased and just can say enough about them. These are top of the line head lamps for sure. And the customer service is even better. Had one HM50R that the battery indicator would blink 3 times with a new battery like it was dead they sent me a new one no question's asked.

Carl Donica

My wifey is a mail carrier so I got this one for her to use during the dark months. She loves it.
