HM55R
The Fenix HM55R Rechargeable Headlamp is the one light you can count on for anything—camping under the stars, working late on a jobsite, chasing the next trail run, or casting a line at dawn. Delivering up to 1200 lumens and reaching 574ft (175m), it combines serious brightness with a compact, easy-to-wear design. Its 1600mAh battery powers nine versatile lighting modes, offering excellent runtimes so you can stay out longer.
Switch effortlessly between the separate spotlight and floodlight or activate the red light to preserve night vision. The large, glove-friendly switch ensures quick adjustments, while the wide, comfortable headband keeps the fit secure during hours of wear. With an IP68 waterproof and dustproof rating, the HM55R is ready for rain, mud, and rugged conditions. Whatever the task or adventure, this headlamp is designed to deliver dependable, all-around performance in a small, durable package.

Output Selection
Intelligent Memory Circuit
The headlamp automatically memorizes the previously used output level and mode excluding Red light.
When turned on again, the previously used output level and mode will be recalled.
*When turned on in Spotlight mode, the headlamp will activate in High output if it was previously switched off in Turbo output.
On/off
On: With the lamp turned off, press and hold the switch for 6 seconds, and the headlamp will blink twice on the Low output of the Floodlight mode, indicating that this function is enabled.
Off: With the lamp turned off, press and hold the switch for 6 seconds, and the headlamp will blink 8 times on the Low output of the Floodlight mode, indicating that this function is disabled.
Intelligent downshift
When the light head is close to an illuminated object (about 2.36''/60 mm) for more than 1.5 seconds in Spotlight mode or Floodlight mode, the headlamp will automatically reduce the brightness level to 30 lumens to avoid potential danger/burns caused by high temperatures. When the light head is away from the illuminated object for more than 0.8 seconds, the headlamp gradually recalls the previously used brightness level.

*18350 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property. Any adverse effects resulting from the use of low-quality batteries are not covered by any Fenix warranty or liability. Using quality batteries with circuit protection will reduce the potential for combustion or explosion.
*CR123A batteries should be reserved for emergency use only. Do not recharge while using a CR123A battery! Using a CR123A battery will reduce available output levels and shorten runtime. For optimal performance, it is recommended to use a Fenix ARB-L18-1600 battery.
Battery Replacement
Unscrew the battery cover counterclockwise and insert the battery in accordance with the polarity marks, then screw the battery cover back on.
The indicator will display red while charging and will turn green when fully charged.
Once charging is completed, be sure to unplug the charging cable and close the anti-dust cover.
Note:

*This feature only works with a Fenix ARB-L18-1600 battery, a Fenix ARB-L18-1100 battery, a Fenix ARB-L18-1100P battery, a Fenix ARB-L16-800UP battery, or a Fenix ARB-L16-700UP battery.
The headlamp will accumulate a lot of heat when used at high output levels for extended periods. When the headlamp reaches a temperature of 55°C/131°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 55°C/131°F, the headlamp will gradually recall the preset output level.
When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until the lowest output is reached. When this happens in the lowest output, the battery level indicator blinks red to remind users to recharge or replace the battery in a timely manner.

Adjust the headband by sliding the buckle to the required length.
If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage.
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 O-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: Poor battery level.
Solution: Recharge or replace the battery.
B: The contact or contact point 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 the distributor.
