RovyVon A8 Keychain Flashlight Review

The RovyVon A8 Keychain Flashlight is a special run of the Aurora series – it has a Nichia emitter with a special user interface. Read on!

Official Specs and Features

Here’s a link to the RovyVon A8 Keychain Flashlight product page.

Versions

Of this exact A8, there are two options.  They differ only in the secondary emitters.  The one here has red, blue, and amber.  There’s also an option with UV, white, and red.  Outside of the A8, there are many lights in the Aurora series, which I won’t get into fully- there are special metal, special finish, different secondary, no secondary, etc.  There are plenty of options in the Aurora series!

Price and Coupon

The price of this model is $46.95, but can be discounted with the coupon “zeroair”.  Buy the RovyVon A8 Keychain Flashlight here!

Short Review

I liked the Aurora series, and I like it even more with Nichia.  I will gladly take lower output in exchange for a Nichia 219c emitter.  The new UI is fine, and I appreciate the lower low.  The light seems to have picked up some unfortunate PWM on the lower modes, but I hear RovyVon is getting that sorted out.

All my RovyVon reviews!

^ 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.

What’s Included

• RovyVon Aurora A8 Keychain light
• Metal necklace
• Pocket clip
• Charge cable (USB to micro-USB)
• Lanyard
• Manual and paperwork

Package and Manual

Nothing new about the package!

The manual is updated for this specific model, with a runtime graph specifically for the 219c.

The manual’s good, and is a single A4-sized paper.

Build Quality

Nothing at all unexpected from this updated Aurora.  The body is a new poly – completely clear and not tinted.  I think this was because of the UV option, to be certain that the body doesn’t impede the UV.  (To wit: RovyVon has considered the fact that polycarbonate blocks UV, and has taken care to prevent it in this light).

Size and Comps

Officially 2.12 x 0.57 in, and 0.03lbs.  I weigh it at 11g.  Eleven grams!  This clip adds about 1g, so 12g total with clip.

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

Retention and Carry

A very good way to carry this light is the included chain.  It’s unusual that this thing is included, but it attaches securely, and carries well on the neck.

The other option is the pocket clip.  It’ll attach on either side of the light, and in two positions, and also in either orientation.  Very versatile.

This versatility allows the A8 to clip on the bill of a cap in a useful orientation, for example.

Power and Runtime

The battery is internal and built-in.  Ie, it’s permanent, and can’t really be swapped.  I performed a runtime on the highest mode.  As expected (per testes on the other Auroras), the output drops dramatically and quickly

In my tests (which go down well below 10%), the light never shuts off.  Output also doesn’t quite hit the claimed 350 lumens, as measured on my device.

I also performed a runtime on the second-highest mode.  Output steps down quite quickly with this mode too, and after the stepdown the output is more or less the same.

Charging

Of course with a built-in cell, the light also has onboard charging.  A cable is included and is powered by USB.

The micro-USB port is covered by a little rubber plug, which is the same as on the E300S.

Below is a charge graph.  Nothing unusual really, except that the CV phase is quite long.

Pulse Width Modulation

PWM is quite noticeable on the lower modes, and can even be seen on the third mode.  It’s completely absent on the highest mode.

Note the scale below – 2ms – and compare it to the E300S reviewed just the other day, where the scale was 50us.  (50 microseconds).  Unfortunately, I find the PWM on low to render the lowest mode practically useless.

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’s one switch on the A8.  It’s a clicky e-switch.  The second biggest difference in this and the other Auroras is the UI.  This one has been reworked (based on Reddit users requests!)

Here’s a user interface table!

State	Action	Result
Off	Click	No action
Off	Hold	Momentary Turbo
Off	Double Click	Moonlight
On	Click	Mode Advance (LMH)
On	Hold	Off
On (Over 3 minutes)	Click	Off
Off	Triple Click	Red/Blue Flash
Red Group	Click	Red Advance (Red/Blue > Red Only flash)
Off	Four Clicks	Amber
Amber Group	Click	Amber Advance (Amber steady > Amber Beacon)

LED and Beam

Everything’s the same about the beam of the light except the emitter.  The emitter has been changed to a Nichia 219c, 4000K and >90CRI.  The optic still gives a beam with mostly spot and a little spill.

The side lights are quite bright…. in fact I would love to have access to lower side modes.  And steady red/blue, not just flashing.

These beamshots are always with 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)

These are the same shot but with different settings – I thought the second one was easier to understand.  (The top one is included just because it’s the same settings as all the others I’ve done.)

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

Conclusion

What I like

• Nichia Emitter! Yay!
• Amber side light – it’s my preferred secondary!
• Same good build quality as the other Auroras
• Can be used on the bill of a cap for running or hiking etc.
• Micro-USB charging works well enough

What I don’t like

• PWM
• Red/Blue flashly only, no steady modes for those
• Battery isn’t replaceable.
