Tip: we also offer the headlamp in a special Fenix HM75R Topaz version without an external battery case in the package and with a number of improvements.

The Fenix HM75R rechargeable headlamp features two light beams with up to 1600 lumens and a powerful red light with up to 120 lumens. The long-range reflector with the high-performance LED Luminus SST-40 produces a well-focused light beam with a range of up to 223 meters, and the floodlight reflector with the high-performance LED Luminus SST-20 has a very wide and smooth light beam with a 60-meter range. The lumen output of the spotlight reflector is up to 1600 lumens, the wide floodlight reflector offers a maximum output of 1000 lumens and a neutral light temperature. The light from both reflectors cannot be combined, can be easily switched between them with the rotary dial on the side of the headlamp.

The headlamp is powered by a rechargeable Li-ion 18650 3400 mAh battery, which is located inside the headlamp. Additionally, it has a removable rear power extender case with a 21700 5000 mAh battery for significantly extended runtime. The rear battery case can also function as a standalone power bank to charge any USB devices, it connects to the headlamp with a USB-C cable that features anti-pull locks. The headlamp can also be operated without a battery inside, with only power from the powerbank via USB-C cable (with slightly reduced maximum power). Also included is a USB-C extension cable with a length of 1 meter, so that the battery case can be hidden under a jacket, for example, to prevent excessive battery hypothermia in the winter, etc.

The headlamp is made of lightweight and durable magnesium alloy, its construction is fully dustproof and waterproof according to IP68 standard and also shockproof against drops from 2 meters.

High performance and durable parameters make the HM75R headlamp suitable for those who want a strong and reliable partner in extreme conditions. It will serve great at work e.g. for rescuers, but also for sportsman, climbers, repairmen, hikers and other outdoor enthusiasts. A nice bonus is the very strong red light.

All headlamp parameters (lumen output, battery life, waterproofing, range and shockproofing) are measured in accordance with ANSI/NEMA FL 1-2009.

Using the HM75R headlamp

From the factory, there may be an insulating cap on the batteries. Remove them before first use.

The headlamp is turned on and off with the rotary switch on the right side. In the first position, the headlamp is off, turning to the second position turns on the spotlight mode, turning to the third position turns on the floodlight mode, and turning to the fourth position turns on the red light mode. The power modes in each position are cycled by pressing a button on the side of the rotary switch.

 Memory for the last set power mode - The headlamp has a memory and will always turn on in the last set power mode of the selected reflector with the exception of the highest power modes of the main and wide reflectors, instead it will turn on in the second highest power mode of that reflector.

Locking of the USB-C cable in the connectors - A USB-C cable is included to connect the headlamp and battery case. The cable is equipped with locks on both ends to prevent accidental removal from the headlamp or battery case. To lock the cable, plug the USB-C cable into the connector in the headlamp and battery case and turn the cable ends clockwise. To unlock the cable, twist the end caps counterclockwise and disconnect the cable.

Intelligent power reduction- The headlamp has a built-in protection circuit. When the spotlight gets closer to the object to be illuminated (to less than 60mm) for more than 1.5s, it will automatically reduce the power to low mode to prevent the object from being damaged by strong light and glare from reflected light. When the reflector is moved away from the illuminated object for more than 0.8 s, the headlamp will automatically restore the previously used power level. On/Off Smart Proximity Sensor - Press the side button on the headlamp for 6 seconds when the headlamp is turned off. Turning on the function is indicated by the headlamp with two flashes in low mode. Turning the function off is indicated by the headlamp with eight blinks in low mode.

Intelligent overheat protection - When the headlamp is used on high power modes for a long time, a large amount of heat accumulates. When the headlamp reaches a temperature of 60°C or higher, it will automatically reduce the power by several lumens to lower the temperature. When the temperature drops below 60 °C, the output will gradually increase again.

 Warning of low battery in headlamp - If the battery voltage drops below the set level, the headlamp will automatically switch to a lower mode until it reaches the lowest power mode. When the lowest power level is reached, the battery charge indicator will flash to remind you to recharge or replace the battery.

Charging and powerbank function

Charging the headlamp - Remove the dust cover and plug the USB-C charging cable into the headlamp's charging port. Replace the dust cap when charging is complete. During the charging process, the four indicators on the top of the headlamp will gradually light up and flash. The four permanently on ones indicate that charging is complete. Normal charging time is 4 hours with a 5 V/2.5 A USB power supply for a fully discharged headlamp.
Note: The headlamp can be used in all modes while charging with the 9 V USB source. The maximum output of the main reflector will be limited to 1200 lumens and the wide reflector to 700 lumens. While charging with a 5 V USB power supply, the headlamp can only be used in the two lowest modes of any reflector. The headlamp flashes several times when first switched on after plugging in the USB power supply to indicate the charging voltage used. Two flashes indicate charging with 5 V and four flashes indicate charging with 9 V. When powered from the USB power supply, the headlamp can be used without the battery inside. Only charge the original Fenix ARB-L18 batteries in the headlamp.

Charging the power extender - Flip off the dust cap and plug the USB-C charging cable into the case's charging port. When charging is complete, replace the dust cap. During charging, the indicator in the button on the battery case lights red. When fully charged, it will turn green.

Back battery case powerbank function- Flip off the dust cap and plug the USB-C charging cable into the case's charging port. One press of the button on the battery case will turn on the powerbank function. If the powerbank is on, pressing the button again will turn it off. After replacing the battery in the battery case, the powerbank function will turn on automatically if it is connected to the headlamp. The power bank supports the following fast charging protocols: PD3.0/PD2.0, QC3.0/QC2.0, FCP, SFCP, PE2.0/PE1.1

Powerbank light load detection function- When the powerbank function on the rear battery case is on, hold the button on the case for 3 seconds. Turning on the low load detection function is indicated by three red flashes of the indicator LED in the button. Turning the function off is indicated by eight red flashes. This function is designed to charge USB devices with very low power draw, such as fitness trackers and wireless headphones. With the low-load detection feature enabled, the powerbank will automatically stop discharging when the headlamp is fully charged. To restart the powerbank function, plug the USB-C cable back into it or press the button on the battery case. With the low-load detection function disabled, turn off the powerbank function with the button when the headlamp is fully charged to prevent unnecessary discharge of the battery in the rear battery case.

Battery status indication when the powerbank is turned on - If the battery is sufficiently charged, the button on the case flashes green, if the battery voltage drops below 3.2V, the button flashes red. The powerbank function will automatically turn off if the battery voltage drops below 3.0 V.

Headlamp battery charge indication - When any button is pressed briefly (headlamp must be off), the LED battery charge indicator on the top of the headlamp is activated. Four lit LEDs indicate that the battery is 80-100% charged, three lit 60-80%, two lit 40-60%, one lit 20-40% and one flashing LED indicates that the battery is less than 20% charged.

Indication of battery charge status in the battery case - Unless the rear battery case is plugged by cable into the headlamp or other USB device, the battery charge status of the battery in the case can be detected by pressing the button. If the indicator LED is green when the button is pressed, the battery is more than 85% charged. Green flashing indicates 50-85% capacity. If it glows red, it is 25-50% charged. Red flashing indicates less than 25% battery capacity remaining.

Changing batteries - Unscrew the headlamp cap and insert the battery with the plus pole facing into the headlamp. Then tighten the headlamp cap fully again. When replacing the battery in the rear battery case, insert the battery with the plus pole facing out. If the caps are not fully tightened, the headlamp and battery case will not function properly.

Warning
