Intelligent Overheat Protection

The lamp will accumulate a lot of heat when used at high output levels for extended periods. When the lamp reaches a temperature of 60°C/140°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C/140°F, the lamp will gradually recall the preset output level.

 

Low-voltage Warning

When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output, one of the battery level indicators blinks to remind you to recharge or replace the battery.

 

Headband Assembly

Notice: The headband is factory assembled by default. Adjust the headband by sliding the buckle to the required length.

 

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the lamp and will void the warranty.
  • Fenix recommends using excellent quality batteries. 
  • If the lamp will not be used for an extended period, remove the batteries, or the lamp could be damaged by electrolyte leakage.
  • Turn off the lamp and take out the batteries 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: Low battery.
    Solution: Recharge or replace the batteries (Ensure batteriesare 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 the distributor.

Dim light

I bought this because it was rated 1600 lumens. When I compare it to my HM61R, 1200 limens, it is not even half as bright. I am disappointed with it.

There are several factors that are going to go into 'brightness' on the light, primarily looking at candela on any given level as opposed to lumens. Also, are you comparing the turbo of the floodlight or the spotlight to the HM61R? The HM75R has so many options that also affect the runtime and brightness - if you are using spotlight ot floodlight, are you running it on just the 3400 battery or the 3400 battery plus the backup 5000 battery etc. But ultimately, a more accurate number to look at for 'brightness' will be candela over lumens.

Great headlamp

This headlamp is by far the best fenix I’ve ever own. Wish the lamp has programmable settings.

Great headlamp

I was first introduced to Fenix by a coworker and I got the TK35UE V2.0 Flashlight over three years ago and it still works like it’s brand new. I’ve tried other headlamps but they always break during extreme sports. Highly recommend this headlamp if you want something reliable and will keep you safe when you need it most.
Also the batteries they make for these things are amazing, I still use the batteries on my first flashlight from them and they last just as long as the first day I purchased them.
I would recommend this brand to anyone who wants a quality light that will work in any condition.

Game Changer

“Work looks better in the dark” no longer a good excuse! Wooden boat work: time under boat on creeper repairing and painting, awkward work in the bilge, hull painting, millwork detailing—all more efficient and of higher quality with the illumination provided by this headlamp.
Auxiliary battery time worth the cost. Not cheap but has already more than paid for itself. (Bought a DeWalt headlamp before this one and it was useless.)

Exceptional Headllamp

This is the very best headlamp I have ever used. I use it primarily for hunting. I especially like being able to go straight to Red and the easy to use brightness setting of the headlamp, This headlamp gives the user the ability to individually set the brightness of the Spot, Flood, and Red lights. When I turn on any of the lights, I know how bright each light will be when I turn it on, without having to toggle thru various brightness setting. Love this headlamp!!!
