Skilhunt H04 Mini RC Headlamp Review – The 18350 Headlamp you need?

The new kid on the block is the Skilhunt H04 Mini RC 18350 Headlamp.  Skilhunt had remarkable success with the H03 Headlamp, and then had a bunch of H04 variations.  I’m pleased that they added one more, the H04 Mini! Read on for some thoughts and testing.


Official Specs and Features of the Skilhunt H04 Mini RC 18350 Headlamp

Here’s a link to the official product page.

Versions

There are a few versions, all of which fill a different role.  There’s the H04F Mini RC, H04R Mini RC, and H04 Mini RC.

skilhunt H04 Mini RC 18350 headlamp variations

Also available are neutral white and cool white variations of all these lights.  What I have specifically is the H04 Mini RC in NW.  I believe pictured above is the CW variation.

Price

As reviewed, these are going for $52.90 at killzoneflashlights.com (referral link.) The other variations are $53.90 (H04R Mini RC) and $54.90 (H04F Mini RC).


Short Review

I love this just exactly as much as I expected to.  And that’s saying something – with how many Skilhunt H0 series headlamps I have, I have high expectations.  This is a great small headlamp option!

Build Quality and Disassembly

The build quality of the Skilhunt H04 Mini RC Headlamp is great.  If you’ve experienced the H03 or H04 headlamps (and you really should have), then the H04 Mini RC will be no surprise at all for you.  The H04 Mini RC is literally just a shrunken down version of the 18650 body Skilhunt headlamps!

It’s really quite small, too.  The head has very deep cooling fins.

The body has minimal design features, including the waist for connecting the pocket clip.

The tailcap is very easy to remove by unscrewing, but doesn’t have all that much grip.

Jody at KillzoneFlashlights.com gave me the choice of versions and of course I went with this one.  Though in retrospect, the reflector version (“H04R Mini”) would have been a very good choice as well.  I just really like TIRs.  This one is very floody.

There’s a bit of branding, which you can see here, and also what’s seen above on the side of the head.

The charge port is exposed on the top of the H04 Mini.

The tailcap is very plain, but inside is a magnet.

The magnet is easily removable.  Just squeeze the legs of this spring, and remove it, then remove the magnet.

If a light will headstand, I’ll show it here (usually the third photo).  If a light will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s 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 format.

Here’s the H04 Mini RC with another 18350 headlamp I reviewed recently – the Acebeam H17.  Great headlamp!  Notice it’s much taller than the H04 Mini, though.  Interestingly they have practically the same clip.  If you were looking to buy tow 18350 headlamps, the H04R Mini and H17 would be a very good combo!

Here are some of my Skilhunt headlamps.  I don’t think this is all of them, actually, but it’s what I could grab.  The flappy door ones…. I get it.  It’s neat and probably super practical but…  It’s just something to break, I think.

Retention and Carry

The H04 Mini RC is first and foremost a headlamp.  The light clips into the included headband attachment very securely, and easily.

There’s even a double security option – o-rings can be looped over the top to hold the light in even better.

The H04 Mini RC can rotate fairly easily in the connector.  There’s room at the back for the pocket clip, too, but you’ll have limited rotation.

The headband is nice, and has good Skilhunt branding.  It’s a three piece band, with clips that you’ll have to build up yourself.

I wish the manual covered how to set this headband up, but honestly it does not cover that.  Here’s a video by Skilhunt that you will 100% need in order to get the straps right:

With this video, it’s very doable.

The top strap (seen below) is not completely necessary.  The light rides fine without it.  But for heavier exertion exercises, it’ll be beneficial.

Skilhunt has adopted a clip-in connector, and it works very well.  I feel like those holes at the back are screw holes, so if you wanted to wall mount this light, you could.  I…. don’t really know of a good reason to do that, but it’d work.

The second option is, of course, the pocket clip.  It’s a good clip.  Flexible, and deep carry, and the fitment is very snug.

Also the clip can go “up” or “down.”

The clip for the Mini is the same as the clip for the 18650 version.

Power and Runtime

The H04 Mini RC runs on a single lithium ion cell.  It’s sized for a 18350, and an appropriate cell is included.

kilhunt H04 Mini RC 18350 headlamp cell

What’s included is a button top, but with springs on the head and tail, any type 18350 should work fine.

What’s sent is an 1100mAh cell, and that’s a very good capacity for 18350 cells.

The 18350 is installed into the H04 Mini RC in the usual way for flashlights – positive end toward the head.

And in case you forget that bit of information, there’s a sticker just inside the tube to help.

Below are a number of runtimes.  Skilhunt has a bit of a history of stating output numbers for only their cool white options.  What I’m testing here is the neutral white option, so I wasn’t really expecting this light to hit the claimed numbers.  And it didn’t – output falls below the claim by quite a margin.  But again, I knew and expected this.  On one hand, Skilhunt really needs to make the packaging suited for all iterations of a light.  On the other hand, Skilhunt thank you so much for offering NW options in this great emitter, and I can live with the packaging.

Output holds reasonably high for over two minutes, on even the highest output.  Then is very stable for 45 or so minutes, and finally drops off as the cell becomes depleted.

Turbo (T2) is quite stable for nearly the duration, until the cell becomes depleted.

The switch helps to warn the user that the cell voltage is low, too, as follows:

Red blink 4x: >80%
Red blink 3x: 80%-50%
Red blink 2x: 50%-20%
Red blink 1x: <20%

Note that this only happens around 3 seconds after the light is turned on, and only indicates for around 5 seconds.  (I can not say specifically what indication does during runtimes, either – the manual doesn’t even include the information above, about percentages.)  Also note this is a departure from other H04 lights, which had a red and blue indicating option.

In all cases, low voltage protection was observed.

The H04 Mini RC also has built in charging, just like the bigger H04 headlamps.  This charging is by way of a magnetic charge port in the top of the light.

kilhunt H04 Mini RC 18350 headlamp charge connector

A proprietary cable is included.  This is the same type as is used on other Skilhunt lights, so if you’ve “bought in,” you’ll be all set to use this on your other Skilhunts, too.

kilhunt H04 Mini RC 18350 headlamp charge cable

The charger also has a little indicator as well – while charging, the indicator is red.  When complete, it’s blue.

Charging proceeds at around 1A, which is perfectly acceptable for this 1100mAh cell.  One amp is just under 1C, so “just right.”  Note from the graph below that charging is extremely consistent.

Shutoff on bench power at 2.9V.  Runtimes confirm LVP.

PWM

One thing to love about these lights is the lack of pwm.  No mode has even a ripple of pwm.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  And here’s the worst PWM light I have ever owned.  Also one of the very first lights I ordered directly from China!

User Interface and Operation

The H04 Mini RC is operated by a single switch.  It’s an indicating e-switch on the head.  The switch has a silicone cover, and is translucent.  It requires minimal force, and has a positive, quiet actuation.

kilhunt H04 Mini RC 18350 headlamp e-switch

kilhunt H04 Mini RC 18350 headlamp e-switch profile

There are two mode groups.  Mode A and Mode B.  To switch between these Modes, hold the switch from off, for 5s.  The light will flash a few times to indicate the change.  Mode A is the more traditional Skilhunt option, and the one I’ve used here for the review.  It has more output levels.

Mode A Table:

State Action Result
Off Hold 5s Group switch (Indicated by 3 flashes on main emitter)^
Off Hold 1.5s Lockout (allows momentary L2)
Lockout Hold 1.5s Unlock to low mode
Lockout Click Turn switch indicator on/off (Switch indicator = red blink by switch)
Off Hold 0.5s Low (L1 or L2, whichever was last selected)
Off Click On, Mode Memory (after ~3s, switch indicates battery level for 5s*)
Off Double Click Turbo (T1 or T2, whichever was last selected)
Any Triple Click Strobe (memorized strobe).  Strobe options: Fast strobe (S1) > Beacon (S2) > Slow strobe (S3)
On Hold (0.5s) Off
On Click Mode advance (LMHT cycle, of your memorized modes from each level)
On Double Click Advance between sub levels (ie T1 goes to T2 and back, M1 goes to M2 and back) – Memorized to the selected Submode. (Including Strobe**)
Strobe Click Main mode (memory)

Mode B Table:

State Action Result
Off Hold 5s Group switch (Indicated by 3 flashes on main emitter)^
Off Hold 1.5s Lockout (Momentary memorized L1 or L2 is possible)
Lockout Hold 1.5s Unlock to low mode
Lockout Click Turn switch indicator on/off
Off Hold 0.5s Lowest programmed option (Can be L1/L2 but might also be M1 or whatever).
Off Click On, Mode Memory (Switch indicates battery level for 5s*)
Off Double Click Turbo (T1 (always T1))
Off Triple Click Memorized strobe mode SOS.^^ Strobe options: Fast strobe (S1) > Beacon (S2) > Slow strobe (S3)
Strobe Double Click Strobe advance (and memorize)
On Click Off
On Hold Mode advance (LMHT cycle, depending on what modes you’ve selected – you can actually add all the subgroups from T2 all the way down to L2 for 8 modes total in the main rotation!).  On the flip side of that, it’s possible to remove all modes down to two modes (with T1 always accessible via double click).  It seems that any two (non T1) modes can be selected!
Strobe Click Off
On Triple Click Enter programming mode.  Main emitter will ramp output from lowest (L2) to T2.  The indicating switch will be red if the output is active in the mode cycle, or not lit if the output level is inactive in the mode cycle.  When the light cycles past a mode you want to iterate (in or out of the main cycle), click the switch.
Programming Mode Click Turn output (L2 through T2) on (red switch) or off (switch not lit)
Programming Mode Hold 1.5s Exit programming mode
Programming Mode Triple Click Restore to defaults (confirmed by light turning off)
Strobe Group Hold 1s Iterate output level for active strobe mode (L M or H).  This “Hold” isn’t persistent – hold again (separate “hold” action) to change output level again.  Each strobe can have a different output level.

^ The manual says the indicator for switching between the two groups is three fast then three slow by main emitter (entering Mode B) or three slow then three fast (entering Mode A) but I find that it’s actually just three flashes (period.)  Three low flashes = entering Mode B.  Three higher flashes = entering Mode A.
* Battery indicator: Constant Blue: 80-100% power.  Flashing Blue: 50-80% power.  Constant Red: 20-50% power.  Flashing Red: <20% power.  If cell is below 3.0V, the indicator switch flashes 3x every 2 seconds.
** Strobe subgroups: S1=Fast strobe, S2=Beacon, S3=SOS.
^^ Triple click from on in Mode B is tricky because this enters programming mode!  I programmed Low out of the sequence once by accident doing this.

Mode A and Mode B are both useful and very similar except a few important, polarizing things.  A requires a hold for off.  B requires only a click for off (but requires hold for mode advance).

Mode B with all the programming looks absolutely confusing but it’s pretty straightforward once you get the hang of it.  I’ll probably stick with Mode A just because I like for some of the choices to be made for me, and I don’t mind hold for off.  If you’re a “click for off” then you can still set the light up just like Mode A but you’ll have the click for off…. Both groups are very good, and it’s nice to see this level of consideration going into a UI!

I’m a little surprised that Skilhunt hasn’t just “moved on” to offering a ramping UI, but I’m also pleased that they haven’t.  I’d rather have specific outputs like this, and this is a good implementation.

LED and Beam

The emitter here is a Samsung LH351d and “High CRI” of 90 CRI.  It’s a great choice, and I love the beam from it.  The emitter sits at the base of a dimpled TIR optic, which provides a beam that’s has a spot and rolls off into a good bit of spill, too.

kilhunt H04 Mini RC 18350 headlamp emitter with dimpled TIR

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

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

Test light is on the left!

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