×

*Disposable lithium battery: it can be used if the voltage is below 1.5V; or it may cause damage to the lamp if the voltage exceeds 1.5V.

Warning: 

  1. Do not use the banned battery in case of circuit component damage that is resulted from overvoltage burnout.
  2. If the lamp will not be used for an extended period, remove the battery from the lamp in case of damage by electrolyte leakage.

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.

Really wanted to like this

I really wanted to like this headlamp. Everything about it seems right, but on medium it lasts about an hour and then dims down to low. Which can be really inconvenient when you're in the middle of unfamiliar woods on a hike.
Physically the headlamp wins a star because of it's adjustability and size.

I like everything except for the battery consumption

This is a great head lamp. Lightweight, uses common AA, nice light spread, nice light color. BUT, when used in Medium, it only lasts ONE hour. Then it drops to Low, You can even see this in the graph. But the Table lists 16 hours in Medium. That's 1 hour in Medium and 15 hours in Low, which is really dim to be useful. I wish the medium had something like 50 Lumens and lasted a couple of hours. As it is, this is not useful for me running at night.

Basic. Functional. Lightweight. Intuitive.

Have numerous Fenix lights. Fan of them all. Got this for mornings getting ready for work. Great for 15-20ft. Easy to handle. Intuitive functioning between modes. AA batteries are plentiful. Only thing I'd add is a long press "Off" to lock the headlamp for backpack storage.

Great light for trail running.

I had a heavier light from this company that works great, just got this one too, to have a lighter option to take on short runs. Works great!
