Fenix HM61R Rechargeable Headlamp Review

Fenix HM61R Rechargeable Headlamp Review

The Fenix HM61R Rechargeable headlamp comes in a slim package that includes a versatile red secondary emitter. Read on for testing!


Official Specs and Features

Here’s a link to the Fenix HM61R Rechargeable Headlamp product page.

Versions

As far as I can see, there’s just one version of the Fenix HM61R rechargeable headlamp.

Price

The Fenix HM61R rechargeable headlamp is available from Fenix-Store.com for $84.95.  That includes the 18650 seen in this review, too!


Short Review

This Fenix headlamp is not all that, unlike some other 18650 headlamps I’ve seen and reviewed here.  But the built quality is commensurate with the price.  The user interface is very good.  There’s a nice secondary which doesn’t suffer from some silly bad beam profile.  Multiple carry options are included – and that includes a clever headmount, too.  All in all, this is a very solid offering from Fenix.

^ Measurement disclaimer:  Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

Build Quality and Disassembly

feature photo

While this Fenix headlamp is “just a right angle 18650 flashlight” is has a very high build quality.  It somehow manages to feel sleeker than other lights in this category (at least among the many copies I own, some of which you can see below).

I think the perceived sleekness has to do with the head shape.  It tapers very nicely toward the back.

cooling fins

The body isn’t overrun with grip, but this banding is sufficient in my experience.  Primarily this light is probably going to be in the headband anyway.  And in that sense/usage, the banding will help with the user experience.

body grooves

The tailcap is another place where nice touches are evident.  If you chose to swap the cell (you might not – there’s built-in charging) you’ll find the tailcap to be very “soft” in-hand.  The usually sharp edge has been beveled very heavily, and the grip isn’t knurling so doesn’t grab skin too aggressively.

tailcap grooves

These big beefy threads also lead to a pleasant experience.  They’re smooth, square-cut, anodized, and well lubed.   Since they’re anodized, an electronic lockout is possible by loosening the tailcap just a bit (maybe 1/8th of a turn.)  If you noticed the quescent current from the table above you’ll note that mechanical lockout is probably something you’ll want to do – the parasitic drain is fairly high here.

square threads

Here you can see the magnet in the tailcap.  I didn’t overstress it, but that spring did look to be removable.  You could probably remove that magnet if you wish.

tailcap spring

The head contact is just a flat brass button.

head and tail contacts

I didn’t access the head end.  The head doesn’t come off the cell tube, and the bezel is either press-fit in, or screwed in with no access from the outside.  It’ll take a lot of determination to do emitter swaps on this headlamp.

Size and Comps

If the flashlight will headstand, I’ll show try to it here. If the flashlight will tailstand, I usually show that here, too.

in hand

Here’s the test light with the venerable Convoy S2+. Mine is a custom “baked” edition Nichia 219b triple. A very nice 18650 light!

And here’s the light beside my custom-engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

beside torchlab boss 35

Here you can see the Fenix HM61R Rechargeable Headlamp with some other 18650 headlamps.   It competes very well on size.  The Skilhunt H03 and H04 are stalwarts in this category, and the HM61R is essentially the same size, with as many or more features.

Retention and Carry

Though this is primarily a headlamp (headlamp is right there in the name), the Fenix HM61R isn’t “headlamp” in the way the HM65R-T is.  The HM61R can easily be carried as a pocket light or a number of ways.

But first, let’s talk about this headband.  The manual paints a different picture, but this headband comes fully “built up.”  You don’t have to worry about connecting the over-the-top band.

The part you can see below, where the light actually connects, is hard plastic.  It has a nice contour, so does fit comfortably.

headband detail

That channel you can see at the back of the connector is important – more on that later.

headband detail

It would be possible to remove the over-the-top band.  The easiest way would leave that connector you can see below in place.  The harder (more permanent) way would be to unthread that back connector, too.  Either way would work.  That back connector is not hard plastic like the front light mount.  It’s soft and very flexible.

headband detail

You’ll still have the connection point on the front, even if you remove the over-the-top band.

This band is very branded and stretchy.

THe HM61R rechargeable headlamp attach points are much like the Armytek mount.  You can see a review of one like that here.  It’s a good, and well-regarded mount.

First, the light clicks into these two arms.  It’s a clicky and very positive connection.

headband detail

As a backup or security for the mount, there’s this stretchy band that pulls over the headlamp and fits over a groove on the top side of the headlamp.

headband detail

This mounting system is very secure.

Another thing you can see both above and below is that the headband mount can be used with the pocket clip attached.

headband detail

Not only that, but the headlamp may still be rotated (or adjusted/pointed) while in the band and with the clip installed.  That’s what the channel at the back of the mount (mentioned and show above) allows.  The clip slips into this groove and stays there while the light is rotated.

headband detail

The pocket clip is a standard friction fit clip and can connect only on the head end.

Clip hug!

Technically the clip can also be friction fit over the headband groove on the tail end, but that does mean the headband can’t be used.

Finally, there’s a magnet in the tailcap.  This magnet is strong enough to hold the light horizontally.

Power and Runtime

The HM61R is powered by a single 18650 cell, and one is included in the package.  It’s a 3500mAh button top 18650.

included 3500mAh 18650

The included cell is a button top, and you’ll have to use a button top.  Flat top cells will not work.

The cell goes into the Fenix HM61R in the normal way – the positive end goes in first.

included 3500mAh 18650 installed

Below you can see a few runtime graphs.  I didn’t observe low voltage protection on bench power, but during these tests, you can see that the output clearly steps down very far.  Also, at this point, the switch is indicating low voltage by blinking red.  The switch does more, but we’ll talk about that later.

Charging

While the Fenix HM61R headlamp does have a recharging feature, it’s by way of a proprietary magnetic connector on the head.

magnetic charge port

I’m 100% positive this connector looks exactly like a character from Star Wars but also completely drawing a blank on which one.  That’s just a bit endearing, to be honest.

magnetic charge port

magnetic charge port

A cable is included.  It’s USB to proprietary magnetic.

charge cable

There’s a tiny LED on the charger that indicates charge status.  While charging, the indicator will be red.  When either not charging (disconnected) or charging complete, the indicator will turn green (according to the manual), or orange (according to my usage.)

charge cable in use

It’s unclear if the indicator will turn orange or green, to be honest.  You might say “well why didn’t you wait til it was complete to know” – during testing I did wait.  I checked the logger and could clearly see that charging had stopped but as you can see in the graph below, stopped might not also mean completed.  I have no way to know if the charging would top the cell by being left on the charger for longer, or if 4.13-4.15V is “about done.”

charge graph

Either way, the charging is “good enough” – it’ll switch from red no matter what it switches to – green or orange.  And 4.15V ish is just about full – topping the cells off with a bay charger really does not add much to the cell.

Another great feature about this charging is that it charges standard button top cells – there’s nothing special about the setup.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 1200 2h 1171 3.24
High 400 4h 421 0.70

Eco 5 300h 6 15.2mA
Low – Red 1 400h 9.41mA
Med – Red 5 80h 55.4mA

Pulse Width Modulation

There isn’t any PWM at all on the white light.

The lower red output does have PWM.

Here you can see a “baseline” – a chart with almost no light hitting the sensor.

Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.

User Interface and Operation

The Fenix HM61R rechargeable headlamp has a single e-switch for operation.  It’s on the top side of the head and is a very nice switch.  It’s big, easy to access, and easy to press.

e-switch

The action is very low.

With regards to the headband mount – the light can go into the mount in either orientation, so is suitable for both righties and lefties.

Here’s a user interface table!

State Action Result
Off Click Battery status indicator in switch^
Off Hold (0.5s) On (Mode Memory)
Off Hold (1.2s) Red Low (Technically mode memory White first)
On – White Click Mode advance (Eco > Low > Med > High > Turbo)
On – Red Click Mode advance (Low > Med > Flash)
On Hold (1.2s) Iterate red (always to Low) / white (always to mode memory)
Off Double Click Lockout (indicated by 3 blinks from main emitter)
Lockout Double Click Unlock (to on!)

The battery status is reported as follows:
Steady Green: 100-85%
Blinking Green: 85-50%
Steady Red: 50-25%
Blinking Red: 25-1%

The user interface is quite simple really, and I like it.

LED and Beam

The main (white) emitter in the Fenix HM61R rechargeable headlamp is a Luminus SST-40.  I can’t see where Fenix states the CCT, but based on the images below I thing we can agree it’s cool white.

emitter

The emitter (emitters actually) are behind this optic, which you can see below.  I don’t see a way to get the bezel off, and so I’m unsure about emtiter swaps on this headlamp.

emitter behind optic

optic profile

The red emitters are hidden behind that optic too.  There are two red emitters, and they are on either side of the main emitter.  It’s acutally a very nice setup, and provides a very even red beam pattern.

emitter on

These beamshots always have the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left and the BLF-348 reference flashlight on the right.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Conclusion

What I like

  • Complete package
  • Very nice application of secondary (red) emitter.  The beam profile is great
  • Good user interface, with the secondary emitter not getting in the way.
  • No strobes on the white mode
  • Pocket clip can be used while the light is in the headmount
  • A standard button top 18650 works fine
  • Hits throw and output specifications

What I don’t like

  • Recharging is proprietary magnetic
  • High parasitic drain
  • Access to red is always through mode memory of white (even if mode memory is Turbo).  Should absolutely be White Eco then red (which would also provide always-access to Eco white).
