The Product

RovyVon is a fairly new brand, and they're making a big name for themselves with the tiny keychain lights in their Aurora series. There's almost too many lights making up this series, with a wide variety of interfaces, materials, colors, and LEDs available. Today I have the A8 U, which has a high CRI main emitter with a clear body and white, red, and UV side LEDs. It's also worth mentioning the extremely similar A8 Y, which replaces the UV LED with an amber colored one.

Spoiler

I'll admit that I initially didn't see the appeal of these lights, but after playing with it for a bit, I'm convinced. These are a ton of fun, cramming way more power and features than I would expect into something of this size. The momentary mode is perfect for a light designed to be kept on a keychain and, as finicky as the UI can be, it's great for making sure the light doesn't stay turned on in a pocket. As much as I usually don't find blinky or colored modes to be practical, the red beacon on this thing is great. Combined with the clip and the small size, it's easy to clip this onto a backpack as a secondary bike light or pedestrian light.

All that being said, it's not a perfect light. I have some concerns about the cell life in the long term (though these are mostly speculative) and wish there was a way to replace it. I also find the PWM on all but the highest mode to be pretty easily visible.

Physical Dimensions



The light measures 55 mm long, 14.5 mm at the head, and 12.2 mm thick. Pictured next to a Loonie above, you can see it will easily disappear into any pocket. Even with the clip installed, it weighs a mere 14 grams.This is by far my smallest flashlight, but here it is compared to some of the rest. Left to right that's the YLP Scorpion X8, Nitecore TUP Acebeam UC15 , JetBeam Jet-u, and BLF-348

Build





Surprisingly this light features a stainless steel bezel. I love to see this material used on keychain lights, since it's harder than most keys - that means it doesn't get beaten up too quickly like most aluminum lights. I'm not sure if the bezel is pressed or glued into place, but it's certainly not easily removable.The body of the light is made of a clear polycarbonate, and brings back fond memories of old game consoles. The top side has a switch near the head, and a clear section showing the three side LEDs. The opposite side has some printing on it indicating the brand, model, and other information. Below that is the cover for the micro-USB charge port. I've had mine in a pocket with my keys for a few weeks now, and the plastic doesn't show any major wear as a result.The tail has a loop in case you want to attach it to something, with the website printed on it. This light won't tail-stand, and obviously mechanical lockout isn't an option.

What's Included

The light comes in a black and orange box with a window showing the light. Inside, it includes: The light comes in a black and orange box with a window showing the light. Inside, it includes:

Micro USB to USB-A charge cable

Clip

Paperwork Just as an aside, I absolutely love these short little cables for travel and use with powerbanks - they pack up a lot nicer and, if I'm carrying multiples, I really only need one with any sort of reach. I recommend you pick up a few if you don't have any.

Ergonomics and Retention

This light is tiny enough that ergonomics almost don't matter - but it fits fine between your thumb and fingers, and the switch has a good feel to it. Neither the form factor nor the battery life is meant for much more than that as a handheld.



The loop on the back can be attached to a keychain, but RovyVon also includes a lanyard and a "necklace" you can slot through. The lanyard is almost laughably large compared to the light, but it works. The necklace is a bit too reminiscent of a bath chain for my liking, but it's functional and easy to swap out if you want something snazzier.

I personally don't often clip lights this small to my pocket, but the reversible nature of this clip makes it great for clipping to a hat and using it as a headlamp. It can also be clipped to a jacket or bag when using the side emitters and blinking modes for a great locator beacon.

Modes and Interface



From off, press and hold for momentary high

From off, double click to turn on main LED in moonlight

From off, triple click to turn on the UV side light

From off, quadruple click to turn on the white side light

From on, click to cycle through the modes (moon, low, mid, high) or side LEDs (UV, red, red flash)

From the main or colored LEDs, hold for off

From the white side light, click or hold for off There's a lot going on here, but it's mostly very well laid out. It all seems to be designed so that a single click or a hold from off won't leave a light on in your pocket, and if it does somehow turn on, holding will turn it off from any mode. I find the beacon-like blinking pattern they chose much more useful than a strobe mode as well. I'll preface this by saying a larger light with this UI would be awful - but a little backup keychain light like this is well suited to it, and it's very functional.

Light Quality and Beam

The main LED is a high CRI, neutral white 219C, easily one of my favorite emitters. The beam and color are great, but all modes except high have very noticeable PWM. It actually took me a while to pick up on this because I usually use the light in very short bursts and for stationary subjects, but it's quite annoying once you see it.

This might be for the best, since it's pointed right at your face when you turn it on. The red is... well, red, and the white light is fine, though not as nice as the 219C used on the front. I can't actually imagine what purpose this white LED would serve that the front LED doesn't already, but maybe it will be useful for some - let me know what you might use it for.

Power and Runtime

The light is powered by an internal pouch cell, and is not user replaceable. Getting this much output out of a cell this small is sure to strain it over time, so we'll have to see how these hold up after a year or two.

Getting this much output out of a cell this small is sure to strain it over time, so we'll have to see how these hold up after a year or two.I tested the highest two modes of the main LED. Both show output falling quickly for about 5 minutes, before trailing down with the voltage of the cell. Runtime was 35 minutes on high and 75 minutes on medium, both of which are reasonably close to what RovyVon writes on the box.

Charging

Charging is as easy as you'd expect - pull the port cover out and plug into a USB source.

The tests show the current stays well below 0.4 A - it's normal that a small cell like this should charge at a slower rate. The CC phase is pretty short, followed by a longer CV phase. On the second charge, I noticed that there was still current flowing into the light after the LED changed from red to blue, so I set up a timelapse camera to note the change on the third curve.

You can see that the current is still trailing off for a long time after the charge indicates it's complete. The rate is low enough that it won't affect the level of the cell too much - probably about 95% vs 100%. That being said, there doesn't seem to be any proper termination. I can't say for sure, since I can't get at the cells and measure their actual voltage, but initial impression is that the charge may be trickling. If the power draw were just from the indicator LED, I would expect the curve to level out eventually.

Summary

Pros:

Probably one of the most fun light I own - cool look, tons of colors, and well made

High CRI main emitter is great

Huge output for the tiny size

Stainless steel bezel

Decent UI, great use of momentary high (I love easy to access momentary modes) Cons:
