Fenix HM51R Ruby V2.0 rechargeable headlamp, 700 lm
Other product variants
Product description
The Fenix HM51R headlamp is a limited edition that is based on the Fenix HM50R headlamp and offers a number of improvements. For example, a warmer shade of light, a magnetic end, constant regulation in most modes, more red light modes and more.
All lamp parameters (luminous flux, battery operation time, waterproofing, reach and impact resistance) are measured in accordance with the ANSI/NEMA FL 1-2009 standard.
When the headlamp is turned off, it will turn on to the last used white light mode by holding the button for 0.5 seconds. When the headlamp is off, press the button twice quickly to turn on the last used red light mode. The headlamp is turned off by holding down the button for 0.5 seconds.
Switching power modes: If the headlamp has a white light on, short presses of the button can cyclically switch power modes in the order of 3 - 50 - 150 - 400 - 700 lumens. If the headlamp has a red light on, short presses of the button can cyclically switch the lighting modes in the order red 1 lumen - red 5 lumens - red flashing - red SOS. The lamp has a memory and will always turn on in the last set mode (applies to white and red light).
Overheating protection: Operation at the highest mode is limited to 1 minute, after which the output is gradually reduced to approx. 500 lumens for 5 minutes. If the internal temperature of the lamp rises above 60 °C, it will automatically start to further reduce the power in gradual steps until the temperature stabilizes. As soon as the temperature of the lamp drops below 60 °C, the power will gradually increase again. Operation on the 400 lumen mode is limited to 5 minutes, then the output will gradually decrease to 200 lumens for 5 minutes.
Battery charge status indication: If the headlamp is turned off, one press of the button turns on the battery charge status indication for 3 seconds, which is shown by the coloured backlight of the button:
Constant Green: 100 % - 80 %
Green flashing: 80 % - 50 %
Constant Red: 50 % - 20 %
Red flashing: 20 % or less (recharge the headlamp as soon as possible)
The indication works correctly only with rechargeable RCR123A / 16340 batteries.
Charging:
1. Turn off the headlamp. Plug the USB cable into any USB source. Unfold the sealing cap of the charging connector and plug the USB-C connector of the charging cable into the headlamp.
2. During charging, the LED indicator in the button lights up red, after reaching full charge it lights up green. A fully discharged Fenix ARB-L16-700P battery is charged in approximately 1.5 hours.
3. After charging, disconnect the cable and carefully seal the charging connector with a rubber cap to prevent dust and water from getting in.
4. In case of long-term storage, charge the headlamp before storing it. The used battery does not have a memory effect, so it can be recharged even if it is not completely discharged.
5. While charging, you can use the headlamp in 3 and 50 lumen white light modes and all red light modes.
Low battery warning: If the battery drops below the set level, the headlamp automatically switches to lower power modes. If the headlamp is already switched to the lowest power mode and the battery is critically discharged, the indicator in the button will start flashing red. However, the headlamp will continue to shine until the battery is completely empty. The low battery warning is only calibrated to the voltage of rechargeable Li-ion batteries.

Warning
- Do not disassemble the sealed part in the lamp head yourself, this will void the warranty.
- If using a disposable CR123A battery, do not try to charge it in the lamp.
- If the protective rubber rings appear damaged after a long period of use, replace them. The rings must also be lubricated to prevent rubber erosion. By following these rules, the lamp will be properly protected against water.
- If the light flickers, does not switch to higher power modes, or does not light up, it may be for one of the following reasons:
- The battery is almost empty - charge it or replace it.
- The contacts inside the lamp are dirty - clean them with a cotton swab dipped in alcohol.
- The back part of the lamp is loose - tighten it.
