Okay, I have something to confess. This is my first RovyVon flashlight. Although I have seen many RovyVon flashlights on the forums, but never got excited enough to try one out. The reason why I bought this RovyVon A9 is that I want to try this brand out myself. What am I expecting from this flashlight? Don’t know really. I hope it will surprise me.

Package quality and first impression.

Nothing spectacular, but not bad either. It comes in a small little box with the following:

• The flashlight itself
• Lanyard
• O-rings
• Warranty card

One of the main things I believe, is important on keychain lights is the UI. It should have a simple UI and it shouldn’t be activated too easily.

The copper RovyVon A9 has a side switch with a Momentary feature. This means that you can press the switch and the light will turn on, when you let it go, the light turns off. But the output is relatively high. This could be good and bad at the same time. You know when you push that button that you have a few hundred lumens, but at the same time, you’ll be able to run the battery empty when the switch is pressed in.

Since this flashlight is made of copper, it gives a nice amount of weight to it. Not too light, and not too heavy. The lanyard attachment point is at the rear end. On both sides are (what looks to me like) 2 trit slots. Trits are small vials with some sort of chemical liquid that glows for 10+ years.

To activate the light you need to do 2 fast clicks, and with a single click you run from low to high, but it will always start in low.

The package includes a lanyard but also a pocket clip, in case you prefer that. Since it’s a flashlight to put on your keys, the slipperiness doesn’t make it a bad light.

In terms of build quality, I can be relatively short: good!

The flashlight itself is just 1 piece of copper, and can’t be taken apart without the use of tools or heat…or both. Since we are talking about copper, it’s not as strong as stainless steel or titanium.

RovyVon gives 2 years warranty, but it doesn’t really specify what this entails. The second sentence about warranty is this: “Any human-made malfunction or defective is not under warranty”.

It’s great that you can actually choose between 2 LEDs. 1 is the Cree XPG3 (which most flashoholics don’t like) and the Nichia 219C (for Hi CRI).

The version I bought at Amazon is the Nichia 219C with Hi CRI. At the front end of the flashlight you can see the LED inside a TIR optic. And I was kind of expecting a tint with a slightly warm/reddish hue, but this LED doesn’t. There is a hotspot, but it isn’t very distinct. The transition from hotspot to spill is quite smooth. I would call this a decent beam.

If you order it directly from RovyVon.com you can also choose between 2x green trits, 2x blue trits or a mix of 1 green and 1 blue trit. The Trits are located next to the lanyard attachment at the rear end.

The RovyVon A9 uses a micro-USB port for charging. Charging works at a speed of roughly 0.3Amps, and takes about 1 hour to charge from empty to full. One thing I don’t particularly like is the rubber cover on the USB port. After pulling it out completely, it’s not getting back in place when you want to cover it again. Design flaw?

During charging, a blue LED is visible around the switch. This blue light uses a ‘breathing pattern’ during charge, where it slowly fades and comes back. When the charging is finished, the blue light will be solid. I don’t know why they chose this.

Lumen measurements:

All output numbers are relative for my home-made Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.

Mode:	Mfg specs	30 sec	start
Moon	2	1.72	1.72
Low	15	9.76	9.76
Med	260	186	244
High	450	192	474

The specs can’t really be trusted as it seems. Medium Low and Medium are way off. And it seems like they don’t use the ANSI FL1 standards for showing their output, because the output drops in High the moment you switch the flashlight on. After 30 seconds it’s only at 185 lumens and still dropping.

Runtime:

The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.

Full graph all

All modes have a runtime longer than 1 hour, which is great for this small of a light. The Lowest output has a runtime of about 26 hours, which is still less than RovyVon claimed. They claimed a runtime of up to 32 hours in Moon mode.

Low, medium and high aren’t exactly according to specs either.

Specs:

• High: 1.5 minutes + 90 minutes
• Med: 1.5 minutes + 120 minutes
• Low: 10 hours
• Moon: 32 hours

Throw Measurement

Measurements were taken both at 5meters distance with a professional Hagner E4-X Lux Meter.

Mode	Candela measured	Meters	Yards
Low	50	14	15.47
Med	850	58	63.77
High	1550	79	86.11
High @ 30sec	700	53	57.87

Moon was impossible to measure at 5 meters with a 1lux setting. And the specs said it was supposed to throw 850 cd or 90 meters, but that is impossible as well. 850 cd is supposed to be 58 meters, instead of 90 meters. I don’t understand why they claim this. Anyway, it’s not able to achieve 90 meters, even at start. Nonetheless, this doesn’t mean on its own, this is a bad flashlight. The runtime is more important to look at.

For the following beamshots I used a Canon EOS 5D Mk2 and a 50mm lens. manual settings: ISO1600, 1/4sec , F4, 5000K

I compared it to a few small keychain lights, and AA flashlights. You can see that it’s much more powerful than AA flashlights.

Disclaimer: I bought this flashlight with my own money. Nobody paid me to review this flashlight, nor have I been holding back on problems or defects.
