Another RovyVon!  This time it’s the brass version, and one I bought for myself.  That’s a testament to the other two from this series I’ve reviewed – the A23 and A28 – I liked them enough to put my own money into a version.  The A29, brass of course.

Official Specs and Features

Here’s a link to the official product page.


The A29 is a brass version of this series.  There’s a bunch of other bodies, but let’s focus on the A29.  There’s just one version!  One body metal, one emitter option.  Brass and Nichia 219c.  You do end up with some options though, since you can pick which color tritium is installed – or no tritium (which is what I bought).


These go for $79.95 without tritium.  Tritium adds $30, for a total of $109.95.  And it’s available on amazon! (that’s a referral link, too.)

Short Review

As stated above.  I really like this series.  Since I’ve now handled three from the series, I can say I’m a bit frustrated at times by the differences in UI – I wish they’d settled on something then released the light, or at least done something that makes sense.  Otherwise, I love the light!

Package and Manual

Typical RovyVon package and manual.

Build Quality and Disassembly

Great build quality.  Nothing really more to report.  I love the brass.  It’s a great weight for this relatively small light.

The “Hot” triangle warning hasn’t been indexed, just like the other models.  Once RovyVon does the next iteration, maybe that’ll all get lined up.

Some of the shots above and below are reused from my new light day post, and are more glamour shots….


The tritium vials go in the loop on the tail of the light.  They’re good slots.  One of these days I’ll use them.  Would that be a good How Do I… post?


At first I thought there was a difference in the tail loop, but as it turns out, that little cutout is present in the A28 as well.

Threads are made of body material.  They’re short threads, so not a ton of twisting is required.  And of course brass threads are great.

The internals.  I didn’t take it down further than this, because it’s the same as the A23, and I don’t really want to mess up another switch.  So have a look at the A23 disassembly if you want to see the battery.

Size and Comps

Dimensions: 76mm (Length) x 21.5mm (Diameter)
Weight: 83.6g/2.95oz

Retention and Carry

The main means to carry the A29 is the pocket clip.  It’s attached with two Philips screws, which sit flush on the clip.

really like this clip.  It’s easy to use (big mouth), very smooth, and also very deep carry.

Also an option for carry is the lanyard, which is included.  It could attach on the tailcap loop or the pocket clip, since the pocket clip is securely attached (not friction fit).

The included paracord could be attached in much the same way as the lanyard.

The light will tailstand, but I wouldn’t really rely on that much.

The clip isn’t reversible, so this can’t be a hatlight.

Power and Runtime

As stated, the battery is an internal lipo.  It’s technically built in, but the J-type connector can be seen through the body.  However if you replace the battery with one from RovyVon, you’ll be replacing the entire guts of the body.

Here’s a couple of runtimes on the highest main modes.  As you can see, unlike the plastic A28, the output is stable for much longer (1.5 minutes at least) but is still lower than the rated 700 lumens.

Hard to say if there’s LVP but the stepdowns mean you’ll definitely notice when the battery is low.  That said, I’m fairly sure lipos are more resilient (or at least safer) when discharge is low.

High looks about the same, and steps down in the same way.  The stepdown happens later here, so High actually ends up with a higher output rating at 30s, than Turbo.

Of course there’s also built in charging, via micro-USB on the tail.  There’s a press-in cover, which fits securely.  Every time I tried to open this I picked at the wrong end – so just be sure which side to try to snag.  (The tab is very clear to my eye.)

A little less consistent charging here than with the A28, but still fine.  Around 2C on average, which is ok for a LiPo.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 700 1.5m/80m 586
High 450 1.5m/130m 366
Medium 120 150m 123
Low 30 9.5h 31
Moonlight 0.5 72h

Pulse Width Modulation

There’s some PWM around the modes, but it’s very fast and not really noticeable.

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 button is a side switch, just below the head.  It’s a metal-cover e-switch.  The metal button has a metal surround, which both gives a place to find with your finger, and helps prevent accidental presses.

Here’s a UI table!  This light represents the new UI, which has moonlight only from 4 clicks.  But hey at least it’s present.

State Action Result
Off Click No action
Off Hold Momentary Turbo

On Click Mode advance

On >3m Click Off
Off Click 3x SOS
SOS Click Strobe advance (SOS, Strobe)

** The mode is memorized after being on for >3m

LED and Beam

The emitter of choice is the Nichia 219c, which is High CRI (90+).  The other option is a Cree XP-L.  The emitter is under a TIR optic, which I think has seen some changes since the A23 review – see the beamshots of the two for comparison purposes.  A23 beamshot link.  I think this optic might even be a bit different from the A28 optic too.

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

Moonlight isn’t pictured here… I forgot how to get to it, and forgot it was there.  I’ll try to add that back in.  (But since I only owe this Fun Fund Friday review to myself….. ahem….)

Tint vs BLF-348 (Killzone 219b version)

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


What I like

  • The brass is great
  • Has a good weight but small size.  feels important.
  • Tritium slots.  Haven’t added them yet but might just be my first.
  • I just like the build overall.  Not flashlighty but it scratches that itch somehow

What I don’t like

  • UI Ambiguity among all the models
