Short Review

This seems like a good first iteration of the RovyVon Hybrid H3 Pro flashlight.  There are a couple of things I’d like to see be made better, but overall, it’s a worthwhile consideration.

^ 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.

Package and Manual

Build Quality and Disassembly

If you have any RovyVon keychain flashlights (and you should) then the build quality here will be very familiar to you.  You’ll also be able to guess that there’s very little disassembly possible with this light.

Here’s the top-down view!

The tailcap is removable.  These threads are square-cut, anodized, and lubed well enough.  Because the threads are “sort of” short, you need to press the tailcap into the body to get the threads to catch (sort of fighting against that o-ring you can see there.)

Inside is this unusual thing…. that’s a cell “tray”!

We’ll talk more about this later but for now, just have a look.

There are a bunch of contact pins on the inside and on the tailcap, which you can see below.

All in all the build quality of the RovyVon Hybrid H3 Pro flashlight is fine.

Size and Comps

154.5mm/6.08″ in length
17.8mm/0.7″ in diameter
45g/1.59oz in weight

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight 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 formats.

Retention and Carry

A few options for carry are included.  First is this pocket clip.  This is a fairly standard friction-fit pocket clip.

The pocket clip attaches only on the tail end of the flashlight, and facilitates bezel down carry.

Next up is this tactical grip ring.  This ring gets sandwiched between the tailcap and body and is really fairly small.

I don’t…really? think you’re going to be using this one for tactical purposes, however.  You could, sure but…  I doubt this will be your primary tactical flashlight.  If so, the H3 Pro allows a decent modified syringe grip because of this ring.

Finally, we have this lanyard, which attaches…. somewhere.  I don’t really know where it’s intended to attach, actually, since there are no holes to thread it though!

Power and Runtime

Plenty of options for power!  First of all, there’s an internal lithium polymer cell built-in.  This cell doesn’t come out but is rechargeable via a USB-C port.

The second option is to use this battery “tray,” which slides into the light through the tailcap area.

This tray holds AA-sized cells.  And not just AA cells, but also 14500 cells work in the RovyVon Hybrid H3 Pro!  It’s great that both cell types work!

I tried this little tray with various cells – all the types I could muster – and it works fine with button tops or flat tops…  Button tops are too long really but they do work.

You’ll input whatever cell you do use into this tray in the normal way – the spring will contact the negative end of the cell.  Then you’ll put the whole setup into the light in the normal way – the positive end goes toward the head of the light.  Nothing about using it is unusual (aside from the fact that it’s a flashlight with a battery tray, which is unusual off the top.)

Because of these many possibilities, I tested a couple of extra runtime tests.  First is just the internal LiPO, with no other cell installed.

Next, I tested with a lithium-ion cell, a 14500.  Performance is pretty similar to the internal.  Look around the 125-minute mark.  I believe that’s where the 14500 cell drops out and the internal cell kicks in.

Next is one runtime with an AA cell.  Output is claimed lower than with lithium-ion, and that seems accurate.  Interestingly when the lipo battery kicks in (around 105 minutes) the output goes up higher than with just NiMH.

It’s possible to pick whether you’re using the lipo or tray-cell by holding the switch.  If the light is using the “external” cell (AA or 14500), then the indicator is green.  If using the internal lipo, the indicator will be blue.  The light defaults to the external cell!

Charging

Included on the RovyVon H3 Pro is onboard USB-C charging.  The charge port is beside the switch on the head.

An appropriate cable is included (USB to USB-C).

Here are a couple of charge graphs.  Charging is fine.

I also confirmed that C to C charging works.

Disappointingly, only the built-in battery can be charged with this charge port.  The “external” cell (whatever one you put in the tray) will not be charged.  It can be present during charging, but will not charge.

Modes

LiPO/Lithium-Ion (14500) modes:

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens
High	600	35m	427
Medium	200	75m	198
Low	15	12h	22
Moonlight	0.5	56h	0.1

AA modes:

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens
High	120	1h	118
Medium	60	2h	73
Low	10	6h	20
Moonlight	0.5	24h	0

Pulse Width Modulation

Neither configuration has PWM.

AA:

14500:

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

There are two switches on the RovyVon Hybrid H3 Pro.  First is this tactical tail switch.

It’s very proud and very accessible.

The action is fairly deep, and there’s a very positive clicky sound.

Next up is this side e-switch, which also has an indicating feature.  This is a small switch, but on-par with the other small RovyVon keychain flashlights.

These two switches essentially operate the light independently, for very different purposes.  The tailswitch is for tactical purposes and the e-switch is for everyday carry purposes.

Here’s a user interface table!

State	Action	Result
Off	Double Click Side Switch	On (Mode Memory)
Off	Click Side Switch	No Action
Off	Hold Side switch (>3s or so)	Iterate which cell is being used
On	Click side switch	Mode advance (low to high direction)
On	Hold	Off
Off (or “On” if by side switch)	Click Tail Switch	High or Strobe (Memory, recorded after 3 seconds of use)
Off	Half press Tail Switch	High
Strobe	Click Tail Switch	Off

The user interface is fairly straightforward with on exception – using the tailswitch operates over the side switch but does not change the state – once you click the tailswitch off, whatever state the e-switch had the light in, the light will still be in that state.  This is not bad at all, just not common.

LED and Beam

The emitter used in the RovyVon Hybrid H3 Pro is a Cree XP-L HI.  RovyVon doesn’t make a claim to the temperature, but it’s somewhere in the cool white range.

A smooth reflector is used.  This extremely crenelated toothy bezel is removable, but not in the sense that you can use the light without it.  It holds the reflector and lens in.

LED Color Report (CRI and CCT)

A new section for reviews!  This is the first new section I’ve added in a while, and one that you’ll either not care at all about, or be extremely excited about (probably.)  I am still new to testing this aspect, but a massive thank you to Bob McBob for his help in getting this setup.  Also thanks to my patrons from Patreon for some help funding this equipment!

I won’t spend a bunch of time explaining this.  That’s probably worth a whole separate post (which I’m into if it’s wanted?).  Suffice to say that this light does use a cool white emitter.

Beamshots

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

• Interesting unique design to use these external cells
• Uses 14500 (4.2V) and AA (1.5V) cells!
• No PWM!
• USB-C Charging
• Good two-switch interface
• Low (for both cell types) is very low indeed!

What I don’t like

• Does not charge the “external” cell
• USB-C Charging only charges internal cell
• 6000K emitter
• Nowhere to attach the included lanyard
