Review intro:

RovyVon, known for their small form factor EDC lights, has two main lines: Aurora, which are cylindrical, single emitter, keychain lights, with built-in batteries, and Angel Eyes, which are flat, rectangular, multi-emitter, dual-fuel lights (mostly). The latest light in the Angel Eyes line is the E30, which is a much longer light than others in that series. With two tail switches, two emitters, and two batteries, it definitely seems interesting, so let’s find out about it!

What’s in the package

The E30 came in a black plastic case with a plastic clasp on the side and white paper insert. Fairly no-nonsense, but different from the paperboard packaging of most other lights.

The contents of the box include:

  • RovyVon E30, with RovyVon 10880 battery inside (optional)
  • Clip
  • USB-C charging cable
  • Lanyard
  • Instruction manual

Flashlight in use, Build Quality, and Warranty

If you’re familiar with the Angel Eyes series of lights from RovyVon, then you’ll recognize some of their key features in the E30: Flat form factor, dual forward emitters, multi-fuel (built-in battery and removable AAA or lithium ion), and dual buttons. 

Where the E30 deviates from the norm is, first and foremost, that it’s twice as long. This allows it to accept not one, but two AAAs or 10440s, or one 10880 battery. The removable batteries are still accessed by swinging the battery door to the side, though the door is at the rear instead of the front of the light, and the door is held in place by a sliding latch, rather than the loop latch of other models. The differences don’t stop there; the dual buttons of the E30 are located on the tail of the light rather than the top, there are two “wings” (for lack of better term) mounted on the side for using a cigar hold and attaching the lanyard, and the addition of a removable, reversible pocket clip.

The E30 has an aluminum body, but you can get it with standard black anodizing, or with marbled micro-arc oxidation (MAO) anodizing which looks very nice. Classy, even. MAO is less durable than standard anodizing, so it may be subject to damage if you keep it in the same pocket as your keys or drop it, and it tends to pick up dirt as well. I can see some blue from my jeans rubbing off onto the corners of my MAO E30 Pro, but some isopropyl alcohol can take care of that. 

The body is all smooth with no knurling, though there are some indentations on the side which are reminiscent of cooling fins, but they’re not deep enough to provide any meaningful cooling benefit. The top of the light features RovyVon’s lion logo above their signature decorative topography wave with the light name below, while the regulatory information is listed on the back.

Having the buttons on the tail lends itself to being used with an overhand or cigar grip. I had to adjust my cigar grip in order to hold onto the wings of the thinner bodied light, but once I did it worked fine. I prefer the overhand grip, though, as it allows more precision over the buttons. When in the cigar grip, it feels a little wobbly when pressing hard. There are two buttons on the E30 (both e-switches), the EDC button, which is hexagonal and more pronounced, and the tactical button, which is circular, textured, and closer to flush with the tail. Unfortunately, one downside of this configuration is that it makes it very hard to tail stand the light.

The EDC button controls most of the light’s functions; on/off, mode switching, sensor on/off, and battery switching. The tactical button, on the other hand, allows for momentary turbo and strobe, with a half or full press. Regardless of how careful you are, you will turbo and/or strobe yourself with the E30. 

Also located on the tail are two tiny indicator lights for showing which battery you’re using: Lipo or AAA. Three clicks from eco-only mode will toggle between them, though once one battery drains, the light will automatically flip to the other battery source. 

One other interesting feature of the E30 is that it has a proximity sensor. That’s the little black dot in between the emitters. I know this is a turn off for many people, but it can be disabled by holding the EDC button for 5 seconds from off. I’m torn on it. On one hand, when you’re up close to something, too much light creates a strong glare making it even harder to see, so that can make it easier to use and also by stepping down to ~100 lumens, it can prevent pocket fires. On the other hand, having it step down and back up repeatedly as you use it can be annoying. The range varies depending on what you’re illuminating; in testing against a lighter colored surface, the sensor activated about a foot away, while against a darker colored surface, I could get to about 4 inches away before it stepped down. The proximity sensor is only operable on turbo and high, so below that it won’t dim.

Like the other Angel Eyes lights, the E30 has a clip that, well, gets clipped onto the light. While it’s a single-direction clip, you can reverse it on the light so you can use it in the other direction. Of course, that means unclipping it and clipping back on, repeatedly if you want to keep switching it, so that might eventually end up scratching the anodizing. With the clip on “backwards,” it can be clipped to a hat brim, where it holds well and is balanced. In the regular direction, it makes for easy pocket carry. Since the clip location has to be balanced between forward and backwards, the clipping points are towards the center of the light, which has the unfortunate side effect of making it not quite deep carry; about an inch of the rear will stick out of your pocket.

Beyond that, the carry/mounting options are limited. There aren’t any magnets and it can’t tail stand, so you’ll have to lay it flat horizontally or prop it up against something to ceiling wall bounce or illuminate something you’re working on.

The E30’s flat form factor is meant for pocket carry. Since it’s designed for a AAA/10440 battery, it’s just over half an inch (15mm) tall, so it does not make your pocket bulge out. It’s more like carrying a knife than a flashlight. However, it’s not without its downfalls. Being as wide as it is, your hand will bang against it as you put your hand in your pocket, especially with the side wings, and since the clip isn’t deep carry, the rear of the light gets pressed against the grommet of my jeans’ coin pocket when I sit down, and has already accumulated a few tiny chips in the anodizing as a result.

Going back to that battery door, to open it, one of the side wings slides down and you rotate it in the direction of the arrow that’s printed on the back. There’s a spring on the far side of the battery compartment which keeps the battery tight against the post in the door which also pushes it into the rubber gasket that seals the door, and also if you don’t press the battery in far enough when closing the door, it will get jammed against the gasket and damage it. It makes me concerned about its ability to prevent water ingress over time.

The E30 is billed as a tactical/EDC light on RovyVon’s website. It’s definitely a solid EDC light, but I wouldn’t call it tactical. Sure it has tail switches, and one of them handles momentary turbo and strobe, but it has too many functions to be truly tactical. That said, you can EDC it all day long. 

The E30 is covered under RovyVon’s standard warranty (copied from their website): 

Within 2 years of purchase, we will replace or repair it as long as the product is not working anymore because of the factory defects. This does not include obvious user wear or extreme damage.

After 2 years of purchase, if your product(s) got a defective or issues, we’ll offer a discount for purchasing new product(s) at a same or similar value.

LED, Lens, Bezel, Beam, and Reflector

Flat lights like the E30 are just about the only ones to sport dual emitters. Cylindrical tube lights that conform to the shape of a standard lithium ion battery often skip two emitters in favor of 1, 3, or 4, which can be arranged more evenly in that type of setup. RovyVon used the Luminus SST-40 for the E30; an inexpensive, high powered, cool white, domed, 5050 (5mm x 5mm) emitter known for having green tint, especially on low levels. And it does. With positive DUV, even on turbo, the SST-40 drifts into the green territory on the chromaticity chart. Honestly though, I feel like this is one of the nicest SST-40 lights I have. Maybe it’s because the lowest mode is still 10 lumens, and not a true moonlight mode where the SST-40 would be very green. Maybe it has to do with the actual CCT. RovyVon advertises the E30’s SST-40 as being 7000-7500K, but I measured it around 5700K, which I like much better.

These SST-40s are kept behind a TIR lens, which itself is held in place by a thin, steel bezel. The two TIR have a pebbled/honeycomb pattern on them for making the beam floodier, and gives the light a bug-eyed kind of look to it. Even though the TIR is surrounded by the steel bezel and recessed, it’s otherwise exposed (no glass lens), so by having it head down in your pocket, it could end up scratched. 

If you look very closely, you can see that while the TIR does a good job of focusing the two emitters into a single, circular hotspot, the corona is actually rectangular. It really won’t affect your usage; it’s just interesting to see.

Flashlight size comparison with its competition:

Group 2: Mini MagLite 2*AAA, RovyVon E30, Lumintop GT Nano Pro 3*AAA/1*10440

Group 3: RovyVon E30 Pro, RovyVon E30

As you can see, the E30 is a lot thinner than 18650 lights, but it’s wider, which made me curious about which was actually larger. The volume of a cylinder is V = πr2h, and with a Convoy S2+ being 11.8×2.4cm, that comes out to approximately 53.4cm3. The E30 is 12.2x3x1.5cm, which is 54.9cm3! I would’ve lost money on that bet. I got thinking about this because of the battery size. Since the E30 is about the same size as an 18650 light, volumetrically, I guess the trade off for having it lay flat in your pocket is a loss of capacity (1600mAh (900+700mAh) E30 vs 2400 to 3500mAh 18650). You may want to keep that in mind, depending on your needs.

RovyVon E30 : User Interface and Driver

RovyVon has a different UI mindset than other manufacturers and while that of the E30 Pro falls in line with it, it’s somewhat different from other RovyVon models. 

Available modes: 

  • Eco, Low, Medium, High, Turbo

Available blinky modes:

  • Strobe

EDC Switch:

From OFF:

  • Press and hold: On to Eco-only
  • Single click: On to Eco-only mode*
  • Double click: On to memorized level
  • 5 fast clicks: Lockout
  • Hold for 10 seconds: Toggle proximity sensor on/off

From ON:

  • Press and hold: Off
  • 1 click: Cycle through levels
  • Double click: Memorized level, if started in Eco-only mode
  • 3 fast clicks: In Eco-only mode, will toggle between using the built in li-po battery and removable batteries

Tactical Switch:

  • Half press: Momentary turbo
  • Full press: Momentary strobe

Mode memory:

  • The last used mode will be memorized and accessible by turning on with a double-click of the EDC switch.

Shortcuts:

  • To Low: Hold EDC switch from off
  • To Turbo: Half press Tactical switch from any mode
  • To Strobe: Full press Tactical switch from any mode

Low voltage warning/protection:

  • When the voltage is low, the AAA indicator light on the back will turn red.
  • There is LVP on the built-in lithium polymer battery.

Strobe/blinkies

  • Fully press the Tactical switch while in any mode (except lockout) to activate strobe. 

Lock-out mode: 

  • 3 clicks from off will electronically lock out the light. This is important, as there is no way to mechanically lock it out. 

PWM

  • Eco appears to be using PWM, but it’s not visible to the naked eye

Additional/summary info on the UI: 

  • *1C on to eco mode is not officially part of the UI
  • It took me some time to get used to this since there are some major changes from what you could call a “standard” UI, like double-click for on and hold for off. Part of the problem mostly stemmed from the fact that I discovered that one click was enough to turn on the light to eco-only, not just click and hold, and I started using it that way. From there, it was easy to slip back into that “standard” UI mindset of 1C on/off, 1H change levels. Once I stopped using it that way, it became much easier.
  • Turbo is only accessible through the tactical switch

RovyVon E30 Charging and batteries

Like the majority of RovyVon’s lights, the E30 has a built-in lithium polymer battery. This 900mAh battery offers three times the capacity of their smaller models, like the E3, and is charged using the USB-C port on the side of the light.

Like most of RovyVon’s Angel Eyes series, the E30 also has the ability to use replaceable batteries. Just push the tactical wing on the tactical switch side down and swing the head towards the back of the light to expose the battery tube. The longer form factor of the E30 means you have the choice of a 10880 lithium ion battery, 2*10440 lithium ion batteries, or 2*AAA batteries (NiMH preferred, but alkaline works, too, if you must).

You can select either of these battery options by triple clicking from eco-only mode, but the really cool thing is, they work in tandem. When one runs out, the E30 will automatically switch to the other so you can keep going! Some other RovyVons do this, too.

Note that the USB-C port on the light does not charge the replaceable batteries. This makes sense, because while it could potentially determine li-ion vs AAA by voltage, it wouldn’t be able to determine NiMH vs alkaline and charging an alkaline would be dangerous. 

While the E30 is plugged in and charging, you can still use the eco and low levels, and the Lipo indicator light on the tail will breathe. Note that the Lipo light is only blue/red, while the AAA light is green/red, because once the lithium polymer battery is finished charging, the AAA light will be the one to turn green.

When you purchase an E30 from RovyVon, you have the option of including a 10880 battery. If you plan to use one, I’d suggest buying it at that time, mostly because 10880s aren’t very common and therefore harder to find. RovyVon’s 10880 has a USB-C port for charging which is good, because it’s too long to fit into my Vapcell S4+. It’s rated for 700mAh, which sounds about right, as most 10440s are about 320mAh.

Having the option for 10440s or AAAs makes the E30 more versatile and allows it to last longer than the life of the built-in li-po. Just remember that no matter which battery option you choose, the batteries are inserted negative first. Not that you could use it with them inserted incorrectly; under the sliding lid, the post is slightly recessed so the flat, negative end of a battery will not make contact.

Since the E30 uses a built-in battery and a battery that’s too long for my Vapcell S4+, I was unable to measure their actual capacity.

Performance test

Lumen measurements

How Lumens are Measured: Understanding ANSI FL1 Standards How Lumens are Measured: Understanding ANSI FL1 Standards: The ANSI FL1 standards specify that output in lumens should be measured 30 seconds after turning on, as this is the standardized time for measuring brightness according to the industry standard. This is why we focus on this part in our measurements. The ANSI FL1 standards require an ambient temperature of 22 ± 3°C. We record the ambient the ambient temperature to identify potential reasons for any observed discrepancies.

To obtain these numbers, I used an integrating sphere and Extech SDL400 data logging lux meter. Measurements have been calibrated using a standardized calibration light provided by 1Lumen.

Please note the proximity sensor was disabled for these tests.

Unfortunately, the E30 could not hit its numbers above low. The ANSI measurement for turbo (at 30 seconds) was only 730 lumens! That’s lower than the high level measurement at the same time! Even at turn on, turbo only managed to reach 1886 lumens.

Also note that when the battery gets to a low enough level, turbo is essentially deactivated, and using the tactical switch will only get the light to the high level if it’s not already there.

Using two 10440s, the E30 achieved similar output to the 10880 on high, despite having the ability to use twice the voltage, since they’re in series. The alkaline and NiMH AAAs came in at 269 and 183 lumens, respectively, which is on either side of the 200 lumens specification.

Because the lithium polymer battery is built in, I can’t measure draw under load or parasitic drain. The 10880 proved unreasonable as well, since every time the leads disconnected, the E30 would revert to lipo.

RovyVon E30 Battery Life: Runtime graphs

How Runtimes are Measured: Understanding ANSI FL1 Standards About ANSI FL1 runtime standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

To obtain these numbers, I used an integrated sphere and Extech SDL400 data logging lux meter. Measurements have been calibrated using a standardized calibration light provided by 1Lumen.

Since turbo is only accessible by momentarily holding the tactical switch down, I used a rubber band to hold it down for my testing. RovyVon notes that turbo automatically steps down after 10 seconds, as in, this is a timed step down, and not temperature-related. This is present no matter the battery used.

I find it interesting that the specified runtime for medium appears to be the time to shut off, though the others are the ANSI runtime. I wonder if that was a reporting error or if the E30 really does miss the medium runtime specification by over an hour. No matter what level I tested, they all eventually dropped down to eco (10 lumens) before finally shutting off.

You can also see in the graphs how the E30 automatically switches between the batteries when they run out. The “time to shut off” column is taken from the point at which it switches from one battery to the other.

High30min27min1h 24min

Even though RovyVon only gives one set of specifications for runtime, they kind of apply to both the internal and 10880 batteries.

Med3h1h 57min3h 15min
High30min48min2h 16min
Turbo42min2h 13min

If you look at these charts, we have some very different profiles. Alkaline AAA (1.5V*2) starts around 270 lumens, but starts stepping down within 10 minutes; NiMH AA (1.2V*2) holds about 180 lumens for 50 minutes before quickly dropping off; and 10440 (3.7V*2) provides an average of 537 lumens for 31 minutes before sinking like a rock.

Even more interesting is the li-po output after the AAA size batteries run out. The 10440, being lithium ion with higher voltage must keep the E30 on some type of internal “lithium” setting which allows the lipo to discharge to its full potential, while once the alkaline and NiMH batteries expire, the lipo has a longer, steadier, and lower output based on each of their voltages.

Peak beam intensity and beam distance measurements

About Peak beam intensity: Understanding ANSI FL1 Standards About peak beam intensity The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). This means that the intensity has decreased so much, it becomes difficult to see darker objects, or objects that don’t reflect light. The columns ‘Meters’ and ‘Yards’ use rounded numbers.

The numbers for candela were obtained with an Extech SD300 data logging lux meter at 5 and 15 meters, then averaged. 

The throw numbers look good as you go up in levels, until you get to turbo. Remember how turbo steps down after 10 seconds? Well at 30 seconds, there’s no way it can top high by 5000 cd. At turn on, however, it definitely outshone its specification by over 50%! The E30 can initially reach pretty far, but that throw is short lived.

4 stars: ★★★★

While our star rating provides a reliable indicator, we encourage you to read the full review to make an informed decision based on your own needs and preferences.

Flat lights are gaining popularity, and experienced flat light manufacturer RovyVon brings their A game with the E30. More than just an elongated version of the keychain Angel Eyes lights, the E30 is a true EDC pocket light with dual tail e-switches for momentary turbo and strobe, proximity sensor, multiple battery options, and a two position clip.

There are some things which may turn people off, though. RovyVon uses a 2C on/1H off UI instead of the more standard 1C on/off UI, the proximity sensor can get in the way (though you can disable it), the built-in battery will eventually die, it doesn’t tail stand and doesn’t have a magnet, and isn’t nearly as powerful as advertised. Personally, the impending performance degradation of the internal battery is the worst aspect for me.

Despite that, I’ve enjoyed using the E30 so far, and it will join my EDC rotation. Overall, I’ll give the RovyVon E30 4 out of 5 stars and recommend it for anyone looking to jump on the flat light train.
