Fenix HM51R Ruby V2.0 rechargeable headlamp, 700 lm, black
Fenix HM51R Ruby V2.0 rechargeable headlamp
The second generation of the very popular Fenix HM51R Ruby V2.0 rechargeable headlamp offers a luminous flux of up to 700 lumens (ANSI) of neutral white light (4500 K) with reach of up to 120 meters and is also equipped with red LEDs. The Fenix HM51R headlamp is an ideal companion for a variety of sports activities, trips to nature, home and work.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.
Use
There may be a black insulating cap inside the lamp on the battery when you first take it out of the box. Before first use, remove it from the battery.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.

Dobry den,

Hi, I would like advice on the type of bike helmet holder for this headlamp
Diki
Ahoj,
standardne helmet mount Fenix v ponuke k tejto celovke dostupny nema. Popruh je vsak dostatocne dlhy aj na obopnutie prilieb standardnych velkosti, vid.: https://www.bikepacking.cz/wp-content/uploads/2020/11/fenix_hm_51_r.jpg.
Hello. Could you order the strap separately? Thank you

All the answers to questions about delivery, payment, security, returns, warranty and much else.

Hallo, ik woon in Nederland en dit lampje 17 januari besteld en 19 januari "s middags al in huis. Helemaal prima. Netjes verpakt en de levering (inhoud verpakking) komt overeen met de beschrijving op de website, dus: HM51R Ruby v2, Fenix hoofdband, laadkabeltje, 700mAh Fenix accu (16340), draagclip (eenzijdig), reserve O-ring en een mini handleiding met oa. Engels (geen Nederlands). De accu was beschermt tegen ontladen door een plastic schijfje in de dop (dus wel eerste even opschroeven en verwijderen voor het ingebruik nemen). And last but not least; eerste paar keer helemaal opladen, op zijn minst totdat bovenop de oplaadindicatie groen oplicht.
still high satisfaction, the product meets the manufacturer's description, especially the advantages:
Automatically translated- quality processing
- all-metal body
- good brightness and light color
- red light mode
- minimum weight and size
- charging port on the lamp body
- replaceable battery
- universal use - virtually vertical clip and magnet on the battery cover, which allows the flashlight to be used in up to three mounting ways
- thanks to the clip and flashing mode in white and red, it can be used as a flasher for a jersey or backpack
small disadvantages:
- shorter duration
- higher price
ideal as a supplement to the bike light for driving/service or as a universal spare light for bikepacking
in this category, it is difficult to find similar quality light from competitors
all in all, my third product from the Fenix brand and, apart from the higher price, it's hard to fault anything
Super produkt.
Translate by GoogleShow the originalMenil som po dlhsej dobe kedy som pouzival velku celocku s 3 ks AAA clankami umiestnenymi v samostatnom puzdre. Uspora hmotnosti je velmi citit pocas pouzivania na hlave.
Vyhovuje mi siroky pas z vnutornej strany so silikonovou vrstvou zabranujucou posuvaniu celovky napriklad pocas behu.
Je super ze svietidlo sa da lahko odmontovat z plastovej podlozky (pomocou klipu) a pouzivat samostatne alebo lahko upevnit niekam na odev, zavesit kamkolvek v stane a podobne.
Nedavno som ju pouzil po dlhsej dobe a aku-clanok je stale nabity.
Telo svietidla je velmi odolne a nebojim sa posodenia ani pri "hrubsom" zaobchadzani alebo ak by mi celovka spadla a pod.
Excellent lamp, good gradation of modes (it doesn't even heat up in the first three), homogeneous and wide light cone. In low modes, the shade of light is more yellow. My only complaint is the positioning, it's worse with one hand, I usually have to hold the strap to turn the lamp - this is a tax on selectability, other models have fixed step degrees.
Automatically translatedGREAT "lantern"!!!
Automatically translatedI bought it for assembly purposes abroad, and the headlamp is 'nailed' to the helmet with binders.
At the second lighting intensity (of course not in continuous lighting) it lasts a week just fine.
I assume that the market also offers a more durable battery (which would probably extend the luminosity), but personally I don't need to deal with this yet.
I could not have received anything better than such a gift: it has proven itself in terms of durability and lighting capabilities. The integrated battery has a significant impact on endurance in winter/cold weather compared to classic headlamps with replaceable/rechargeable batteries. And good use for reading books at night - the weaker mode is not distracting.
Automatically translatedPerfect lightweight and extremely powerful headlamp. I have been using it for running and hiking for about a month and I am very satisfied. I mostly use white light on levels 2 and 3, and at temperatures from -1 to 7 degrees it lasts about 2-3 hours. I run 3 times a week for 50 minutes and charge once a week.
Automatically translatedThe battery died within a year - it couldn't be charged, but they replaced it without any problems under warranty and the headlamp continues to work fine, so I'm satisfied.
Automatically translatedThe overall is perfect as it is written everywhere.
Automatically translatedI can even put it on the strap without gluing any other holders under the silt on the Fox speedframe helmet
Great headlamp. Gradually 2 more were added, so each family member has their own + a spare Fenix RCR123A/16340 battery and a Fenix APB-20 case.
Automatically translatedExtremely satisfied. Previously I used a Petzl Tikka headlamp. Fenix lights are a class better in my opinion. I bought more for the whole family.
Automatically translatedThe headlamp is super bright, the strap holds up better than expected, removing the headlamp from the holder is difficult, but I don't think anyone will use it.
Automatically translatedExcellent for running, lightweight construction, many light modes, possibility to detach the flashlight and use it as a light for camping.
Automatically translatedGreat satisfaction. I also use it at work and during morning runs. Performance is in reserve. The staying power is sufficient for me.
Automatically translatedHM50R owner for a year and I can't fault these fenix lenses, they are high quality, they last a long time, they shine perfectly..
Automatically translatedI have never had a better flashlight. Light and powerful, I recommend buying it with a spare battery. Then it makes sense

Išlo o vianočný darček, ale obdarovaný skaut je s čelovkou nadmieru spokojný a pochvaľuje si ju.
Translate by GoogleShow the originalGreat. Small but powerful. I probably couldn't buy anything better for that money.
Automatically translatedGreat headlamp - a little more expensive, but you have to pay extra for quality!!!!!
