On/off

Press and hold the switch for 0.5 seconds to turn on/off the light.

Output Selection

With the lamp switched on, single click the switch to cycle through Low→Med→High.
Note: Low mode is activated by default when the lamp is turned on.

Battery Replacement

Unscrew the battery cap to insert the battery in accordance with the polarity marks, then screw the battery cap back on.

Low Voltage Warning

With the lamp switched on, if the voltage level drops below the preset level, the lamp is programmed to downshift to a lower brightness level until low output is reached. When this happens in low output, the lamp blinks to remind you to replace the battery. To ensure normal use, the lamp will not turn off automatically and will work until the battery level runs out.

Headband Assembly

Notice: The headband is factory assembled by default.
Step 1: Attach the headband to the headlamp as shown (Pic Ⅰ-Ⅷ).
Step 2: Adjust the headband by sliding the buckle to required length.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the lamp and will void the warranty.
  • Loosen the battery cover 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 headlamp is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the lamp directly into anyone’s eyes.

    Not impressed at the price point. If I could return/exchange it I would. Auto dims when battery gets hot. Often flickers down to lowest setting with a lot of use. It would be good for light camp site use, but not as a sole means of lighting or using on the job sight. Like I previously said I would return it or exchange it if I could.

    My new HM23 headlamp with a new battery lasted about 15 minutes on the High mode before dropping into Low mode. This is not an isolated incident, it is designed into the headlamp. The graph that is included with the user documentation clearly shows this. This graph is NOT displayed on the Fenix website, only in the included documentation. I purchased this headlamp with the thought that I could run the HM23 at High until the battery wore out (8 hours according to Fenix).

    I view the information for the HM23 on the Fenix website as misleading. It says 240 lumens for 8 hours and it turns out that you can only run it at 240 lumens for a short time. This makes the headlamp useless for me. This should be made clear in your advertising.

      The product page for the HM23 on our website DOES have the graph on it. Is it possible you were looking at the product page for Fenix Store, who is a separate entity than us? I do not see the graph on their product page, but it has always been displayed on our page. The only order we have in our system under your email address is for the HL30, placed the same date you left your review on the HM23.

    I just received this headlight today. For the size and weight, this is a very powerful light. I think i am going to appreciate the automatic dimming, at least on this particular lamp. I am impressed with it. This one will mostly be used under the truck. I like that it doesn’t fall off my head while laying on my back. Great price for what I am getting.
