Product Overview

The Fenix HM65R-DT Dual Spotlight Headlamp is a new version of the best-selling HM65R Headlamp that features dual spotlights—one spotlight of cool white light, for longer distances, and the other with a very warm 3000K light for better performance in foggy, poor weather conditions. Turn both on at the same time for a combined maximum of 1500 lumens. Powered by the included li-ion battery, this headlamp is USB-C rechargeable and includes a battery level indicator. It is made of a magnesium alloy which makes it 30% lighter than similar headlamps made of aluminum. The HM65R-DT with its IP68 waterproof rating is the perfect option for those needing hands-free performance that can weather the elements.

*18650 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use quality batteries with circuit protection will reduce the potential for combustion or explosion; but cell damage or short circuiting are potential risks the user assumes.

Quality Li-ion battery with protective circuit will reduce risks. Fenix ARB-L18 Series battery is recommended.

 

Battery Replacement 

Unscrew the battery cover counter-clockwise to insert the battery with the anode side (+) towards the inner side, then screw the battery cover back on.

 

Charging

  • Uncover the anti-dust cap and plug the USB Type-C side of the charging cable into the charging port of the lamp.
  • The normal charging time of the Fenix ARB-L18-3400 rechargeable battery is about 3 hours with the lamp being switched off. When charging, Low output of white light or warm white light mode can be separately selected. The headlamp will not automatically power on after full charging.
  • When charging, the charging indicators will flash from rear to front to display charging status. In charging process, four indicators flash: below 20%, one constant-on and three flash: 20% - 50%, two constant-on and two flash: 50% - 80%, three constant-on and one flashes: 80% - 95%, four constant-on: charging complete.
  • Replace the anti-dust cap to ensure waterproof and dustproof ability.

 

Battery Level Indication 

With the lamp is switched off, single click either of the two switches to check the battery status, the indicator(s) will last for 3 seconds. 

There will be no response with the lamp locked.

Four lights on: 100% - 80%

Three lights on: 80% - 60%

Two lights on: 60% - 40%

One light on: 40% - 20%

One light flashes: 20% - 1%

Note: This only works with Fenix ARB-L18 Series rechargeable battery.

 

Intelligent Overheat Protection            

The lamp will accumulate a lot of heat when used on high, med and low output levels for extended periods. When the lamp reaches a temperature of 65°C or above, the lamp will automatically step down a few lumens to reduce the temperature. When the temperature drops below 65°C, it will then allow the user for the reselection of the modes. 

 

Low-voltage Warning

When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, one of the battery level indicators blinks to remind you to timely recharge or replace the battery. 

Note: This only works with Fenix ARB-L18 Series rechargeable battery.

 

Headband Assembly 

Notice: The headband is factory assembled by default.

Press the rotary press-pull dial, rotate it clockwise to shorten the headband; pull the dial up to loosen the headband.

 

Usage and Maintenance 

  • Disassembling the sealed head can cause damage to the lamp and will void the warranty.
  • Fenix recommends using an excellent quality Fenix battery. 
  • If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage.
  • Lock the lamp or 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 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: Rehcarge or replace the battery.
    B: The threads, PCB board contact or other contacts are 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.

Amazing Quality

I own two other name brand headlamps. The HM65R-DT is by far the best. The lamp body is finely crafted and fitted to a comfortable easy to adjust headband. I especially enjoy the warm white spotlight. The light emitted is close to that of beeswax candles that I burn in brass UCO lanterns.
Thanks for developing such a high quality light!

Great headlamp, not perfect for biking

Very lightweight, very bright, great battery life, love the headband, but two things are not so good for bike riding. I need a SPOTLIGHT with a sharp narrow focus because I ride in areas with lots of street signs which totally blind me when this headlamp shines on them. The HM65R-DT has a soft focus with too much "flood light." The second thing is that when bent over on the bike for high speed aerodynamics, the light can't be tilted up far enough. Even in the highest position, it points just in front of my tire. I'll keep the light for walking the dogs, but I'm still looking for a sharp beam headlight with a full range of positions.

1200 lumens claim is deceptive

It may start out at 1200 lumens, but quickly drops to 500 after 15 or so minutes (per experience and website’s graph).

Hi Marty - we do try to make sure it it's known that the Turbo lumens levels will drop for overheat protection in the lights.

Great headlamp for trail running.

Having logged thousands of miles with Fenix and numerous other brands (Petzl, Black Diamond, etc) I can confidently say Fenix headlamps are the best trail running headlamp. I have used the HM65R-T extensively as I often run the majority of my weekly trail miles in the dark. It is absolutely fantastic. I purchased the HM65R-DT specifically to have improved visibility in rain and fog. The “warm white light” function does reduce light reflection and therefore slightly improve visibility in dense fog but not nearly as much of an improvement as I had hoped for. Even in heavy rain I still opt for the brighter high or med setting on the cool white light. If you run in dense fog a lot or prefer a warmer light then the HM65R-DT is a great choice. If you want flood and spot options then go with the HM65R-T. Both are top of the line headlamps ideal for trail running.

I am really trying to like this light...

I was super stoked to try this light. I was looking for something bright. Turn it on high and it's pretty much what I was hoping for, but it won't stay in high mode for long as the heat/temp protection kicks in pretty quickly (minutes). I was using it in 30-ish degree (F) weather so I felt like it should have lasted a good while on high but it just doesn't. The medium setting is good light but without the ability to run steady on high in 30 degree weather means the high setting is useless unless you just need it for a few minutes at a time. That's not what I was expecting from this light. This was also my first light with the band that has the wonky adjustment. Not good on a bald head. Need to use a beanie of sorts and that's fine during the winter but I can't imagine using this during a summer hunt to get out of the woods or do any searching. I'll put it with the rest and keep looking.
