Q: Why does the HM55R downshift to a lower mode after being used for a while and the higher mode cannot be selected?
A: There are two reasons:
1. Intelligent Overheat Protection
The headlamp will accumulate a lot of heat when used at high output levels for extended periods. When the headlamp reaches a temperature of 60°C or above, the headlamp will automatically step down a few lumens to reduce the temperature.

When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until the lowest output level is reached.

A: The reasons that may cause the lamp to flicker, shine intermittently or even fail to illuminate:

Solution: Recharge or replace the battery.
C: The contact point or contact of the battery or headlamp is dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods don't work, please contact Fenix-Store.

Q: What kind of battery can be used in HM55R?
A: It is recommended to use a Fenix ARB-L18-1600 battery. Other batteries(e.g., CR123A) are not recommended, as an unmatched battery may cause the headlamp to fail to work normally.

Excellent for trailrunning

"Great headlamp for trailrunning with swappable battery. It has plenty of output and runtime for my evening runs. I wanted a lighter version of HM65R-T and found it but with a single switch. I actually enjoy the single switch to control spot/flood. From reviews it seemed odd but in practice, its great."

Smart sensor ruined this one.

"Well, I thought this was gonna be the one so I ordered another. But unfortunately after realizing they put some type of smart sensor on this light to lower the brightness down when it thinks your working up close to save battery. No matter what I’m doing it’s a fight to keep it on a brighter setting because it keeps turning down. I’m sending them all back. Not worth the hassle"

The perfect headlight

"I have a lot of flashlights and headlamps. Flashlight geek. This new headlamp takes the place of all other headlamps. I have every model Fenix recently made but this 55 is where it’s at. Lightweight a long lasting. The perfect combo. Already ordered another one. Now we just need a usb-c rechargeable backup battery for it."
