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).

Hot on the heels of the RovyVon E30 comes the E30 Pro. Like most of RovyVon’s “pro” lights, the E30 Pro builds on the base of the E30’s dual tail switches and dual emitters by adding three side emitters with their own switch, and employs a much larger built-in battery. I’ve got a good feeling about this. Let’s see if I’m right!

What’s in the package

The E30 Pro 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 Pro
  • 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 Pro: Flat form factor, dual forward emitters, multiple side emitters, and dual buttons. 

The RovyVon E30 Pro 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 the light, but some isopropyl alcohol can take care of that.

While the E30 Pro appears to be similar in construction to the E30, it’s actually fairly different. One major difference is that the E30 has a unibody construction, while the E30 Pro is made up of a top and bottom component. These, and the tail, have a rubber gasket sealing them, but having so much rubber exposed makes me wonder about the long-term durability of it, especially since the gasket on the E30 was easily damaged by the button top of the removable battery.

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 the three side emitters and 4 battery status LEDs elevated above their signature decorative topography wave with RovyVon’s lion logo 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 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 tail of the RovyVon E30 Pro (both e-switches), the EDC button, which is hexagonal and very pronounced (moreso even than that of the E30), 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 Pro. 

One other interesting feature of the E30 Pro 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 Pro has a clip that, well, gets clipped onto the light. Unlike the E30, the E30 Pro clip can only be placed in one direction, bezel down, so you cannot clip this to the brim of a hat for use as a forward facing light. The clip placement is higher than that of the E30, so you get a deeper carry, with about 14mm sticking out of your pocket, vs about 24mm on the E30 (not including the tail switches). One advantage that the E30 Pro has is that you can clip the light vertically to a pocket and use the side emitters like a right angle light! 

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 side emitters on the E30 Pro are a really nice feature. If you choose the 3 white emitter option, you get LMH, while the white/red/UV option has a few more levels than that. On low, the single white emitter is sub-lumen, giving it a true moonlight mode! This is good for moving around at night and avoiding bothering others who may be asleep. The high mode isn’t the advertised 100 lumens, it’s still bright enough to illuminate a room.

If you like using red light for nighttime movement instead, the E30 Pro has you covered. Red low and high are similar in output to the comparable white modes, but you also get flashing and beacon modes! The flashing mode quickly blinks four times. This could be good for nighttime location, but reminds me of the rear light on a bicycle. If you wear a backpack while riding, maybe you could clip the E30 Pro to it. The beacon mode is just a steady 1Hz blink.

And if that wasn’t enough, there’s one UV mode. It’s pretty powerful, though, enough to light up half of a room or more and give me that headache I get when using UV (yes, even with protective glasses). The E30 Pro packs a lot of functionality into a single light!

The E30 Pro’s flat form factor is meant for pocket carry at just over half an inch (15mm) tall, so it does not make your pocket bulge out, except at the side emitters, where it’s more than ¾ inch (21mm) tall. 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, and the side emitters do stick out of the front quite a bit from the rest of the body, which negates some of the benefit of the flat form factor.

The E30 Pro 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. Plus, if you get the white/red/UV option for the side emitters, it’s almost an all-in-one light!

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 Pro 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 Pro; 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 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 Pro’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 with a pebbled/honeycomb pattern on them for making the beam floodier, and gives the light a bug-eyed kind of look to it. One thing to note is that the TIR is much more exposed than on the E30. Not only is there no glass lens or bezel, but the TIR on the E30 Pro is almost flush with the body, 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.

RovyVon doesn’t list what emitters are used for the side lights, but you have two options: 3 neutral white emitters, or like my test model, one red, one white, and one UV. Having up to four types of emitters to choose from makes this a very useful light! The triple white option has three levels to choose from, while the red/white/UV option has two white levels, two red levels and two red blinkies, and one UV level. The UV emitter gets hot fast, so watch your finger placement! The side emitters each have a small aspheric lens, making their output even and circular, with no hotspot. The white emitters are about 4000K and 70CRI while red looks to be about 625nm, and all of the side emitters use PWM, but it’s not noticeable.

RovyVon E30 Pro: 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. Having three buttons might seem like it would bring an additional level of complexity, but it’s not too overwhelming.

  • Double-click the side switch to get to red mode, then click twice to advance to red flashing (bike mode). Another click will activate red beacon.

Lock-out mode: 

  • 5 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. The side emitters definitely use PWM.

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
  • The side switch is not active while the main emitters are in use, and the tail switches are not active when the side emitters are in use.

RovyVon E30 Pro Charging and batteries

Like the majority of RovyVon’s lights, the E30 Pro has a built-in lithium polymer battery. This 3000mAh battery offers ten times the capacity of their smaller models, like the E3, and is charged using the USB-C port on the side of the light.

Unlike most of RovyVon’s Angel Eyes series, the E30 Pro does not have the ability to use replaceable batteries. 

While the E30 Pro is plugged in and charging, you can still use the eco and low levels, and the indicator lights on the front next to the side emitters will breathe. Once charging is complete, all four of the indicator lights will be solid. Since it’s charging at up to 3A, depending on the wall charger you’re using, the E30 Pro can get warm (measured up to 107F/42C). While this is great for quick charging, 3A is 1C (one times the capacity), which is on the high side for charging rate. You may want to consider using an older, less powerful USB wall plug to prolong the battery life.

Since the E30 Pro uses a built-in battery, I was unable to measure its 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.

Overall, the E30 Pro output looks good compared to its specs. The main concern here is that high is only ~80% of spec, but it holds onto that well. You may note that at 30 seconds, turbo is well below the 2600 lumen specification RovyVon gives, but keep in mind that turbo has a timed step down at 10 seconds. While it doesn’t last long, turbo almost got there, with a measured output of 2547 lumens! I was pleased to see that it came through on that promise.

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.

RovyVon E30 Pro 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 only tested it for 30 seconds. Additionally, turbo automatically steps down after 10 seconds, as in, this is a timed step down, and not temperature-related. 

RovyVon did a good job of reporting the runtime. Sometimes I see extreme differences between specification and my measurements, but the E30 Pro came out pretty close. Output is very stable across all modes, so you’ll always have the amount of lumens you expect. No matter what level I tested, they all eventually dropped down to eco (10 lumens) before finally shutting off.

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 7000 cd. At turn on, however, it definitely outshone its specification, by 50%! The E30 Pro can initially reach pretty far, but that throw is short lived.

Beamshots

Camera settings and distance: These were taken with a Samsung Galaxy S22+ using pro mode and the following settings: 0.5sec, ISO200, 5000K. Please note that in this mode, exposure value (EV) is automatically controlled and becomes lower as the brightness increases.

Distance to the other end of the playing field is 100 meters.

Beamshots of the following flashlights compared:

Please note that the following beamshots are mainly intended to showcase the beam pattern and beam quality, rather than overall performance. These images are typically taken directly after activation, and in different seasons or weather conditions, and therefore do not fully represent its overall performance. For accurate performance metrics, such as output, beam distance, and runtimes, you need to look at the performance section of this review.

4.5 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 Pro. More than just an elongated version of the keychain Angel Eyes lights, the E30 Pro is a true EDC pocket light with dual tail e-switches for momentary turbo and strobe, proximity sensor, and multiple side emitters. It also has great regulation, allowing for very good runtimes, and the lithium polymer battery is strong enough to power turbo all the way to spec!

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. Personally, the impending performance degradation of the internal battery is the worst aspect for me.

Despite that, I’ve enjoyed using the E30 Pro so far, and it will join my EDC rotation. Overall, I’ll give the RovyVon E30 Pro 4.5 out of 5 stars and recommend it for anyone looking to jump on the flat light train.
