The RovyVon E10 Professional flashlight was accessible on Kickstarter and has two CCTs of white LEDs, a inexperienced laser, UV, and purple output, and runs two 14500 cells. Learn on!
Official Specs and Options
Right here’s a hyperlink to the RovyVon E10 Professional flashlight product web page.
Variations
At the least two variations of the RovyVon E10 Professional flashlight are (or will probably be) accessible. There’s this increased output model, and a Excessive CRI model, too.
Worth
This assessment hits in some center floor of timing. My assessment copy was hung up in customs for some time! So the Kickstarter is closed, and I don’t assume orders are open but. I don’t even see this mild on Kickstarter any extra (the E10 sure, E10 Professional, no). And it’s not on RovyVon’s web site (E10 Lu sure, E10 Professional no.) So I’m undecided on the worth!
What’s Included
- RovyVon E10 Professional flashlight
- RovyVon 1000mAh 14500 (2)
- Charging cable
- Handbook and so forth
Package deal and Handbook
Construct High quality and Disassembly
The RovyVon E10 Professional flashlight’s construct high quality is okay. The sunshine has a bunch of angles and spots to click on and items that stick out, so there’s only a lot happening. Different customers (particularly on Reddit) have reported that the E10 Professional had some ‘unfinished’ feeling, and I do see a little bit of epoxy that was talked about.
The battery compartment has a lock change. Actually, right here is the place you possibly can see the epoxy. There’s just a little dot simply on the underside left half of that change. I can see why it could be bothersome, however it’s very agency and safe, so hasn’t triggered me any issues.
Right here’s the ‘hinge facet’ of this latching cowl. The hinge presses in opposition to that rubber grip bit, and that gives (or “causes”) a little bit of resistance. It’s very similar to if the quilt have been springy and wished to remain closed. So it’s not an issue, however it causes the closest cell to require deliberate removing. I don’t love this facet of the sunshine (however it’s not precisely an issue.)
The detrimental terminals are each springs and the optimistic terminals are each buttons.
Measurement and Comps
81.8mm x 38.2mm x 28.8 mm and 114.5g
Right here’s the sunshine in hand:
Right here’s the take a look at mild with the venerable Convoy S2+. The model beneath is a customized laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full submit on an engraved orange host proper right here! Or go straight to GadgetConnections.com to purchase your Convoy S2+ now!
Additionally within the picture above, my Normal Reference Materials (SRM) flashlight is the Hanko Machine Works Trident, an 18350 mild. Whereas I’ve not reviewed or examined the Gunner Grip model seen right here, I’ve examined a Hanko Machine Works Trident Complete Tesseract in brass. I really like the Trident, and it’s a hanging distinction to the cheap Convoy S2+, one other nice SRM.
Retention and Carry
The RovyVon E10 Professional flashlight encompasses a screwed-in, two-way pocket clip.
You may see it within the images above, however the entire clip space screws into just a little bumped-out space on the again of the sunshine. I’m not certain what this space is. I’d guess electronics or no matter, however it provides a very good little bit of unwelcome (and annoying) thickness to the sunshine.
The pocket clip has a lanyard loop. No lanyard is included.
And within the tailcap is a magnet completely appropriate for holding the RovyVon E10 Professional flashlight. Sorry, forgot to seize a photograph of that!
Energy and Runtime
The RovyVon E10 Professional flashlight is powered by one or two 14500 cells. Two 1000mAh RovyVon cells are included with the package deal. They’re button high cells with USB-C charging ports.
Each cells go along with the optimistic finish into the sunshine. This does imply the cells are in parallel configuration, and that the sunshine will work with only one cell (in both bay).
You’ll word that there are two runtime exams for Medium mode. That’s as a result of in a single take a look at, one of many two cells was not discharged in any respect (you possibly can see that within the knowledge beneath). One of many two cells wasn’t making contact! (Someway.) So the runtime must be roughly half of what it’d be when you have been utilizing two cells. So I made a decision to check that, and certain sufficient. I discovered that this assessment copy of the RovyVon E10 Professional flashlight has a cell choice. One of many two included cells simply doesn’t work nice in one of many two bays. So what I at all times did for additional testing was put one cell into the “much less nice” bay and ensure the sunshine labored. Then put the opposite cell within the different bay and ensure it labored. It wasn’t an ideal state of affairs, however I additionally didn’t have that downside once more.
A consumer might by no means even discover this, until they have been paying very shut consideration to the precise runtime numbers.
The temperature strains in these charts are included as common context, not exact measurements. The values characterize the vary (min to max) throughout testing, however shouldn’t be taken as precise readings. A temperature sensor will not be at all times hooked up to the bezel (and even the most well liked spot, assuming that might be outlined). Even with preferrred placement, too many variables have an effect on temperature to definitively state a particular max worth.
Charging
The RovyVon E10 Professional flashlight doesn’t provide built-in charging. The 2 included cells do have USB-C charging, although.
A USB to USB-C cable is included.
These cost graphs will probably be a bit uncommon. Because the mild doesn’t have built-in charging and makes use of two cells, to log them, I needed to run them consecutively. I feel most customers would by no means do that. They’re much extra prone to simply throw these two cells in a bay-charger. That’s what I’d do if I weren’t particularly making an attempt to file the information. That’s additionally higher as a result of your cells usually tend to finish at precisely the identical voltage. Much less vital for a parallel (over sequence) setup, however nonetheless one thing I want.

Pulse Width Modulation
Not one of the white LED modes use PWM.
Click on right here to see a “baseline” – a chart with virtually no mild hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has among the worst PWM I’ve seen. It’s so unhealthy that I used a submit about it to elucidate PWM! Listed here are a number of timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make evaluating this “worst” PWM mild to the take a look at mild simpler. That submit additionally explains why I didn’t take a look at the WF-602C on the standard 50us scale.
Consumer Interface and Operation
The RovyVon E10 Professional flashlight makes use of three buttons for management. Within the picture beneath, the left button controls the facet emitters on the entrance. The center (and rotary) button controls the entrance emitters. The fitting facet button controls the laser. The guide names these buttons on this similar manner.
Along with all of the buttons, there’s an OLED show. It reveals voltage, output, and which emitter is on.
Right here’s a consumer interface desk!

LED and Beam
The 2 entrance emitters look like Luminus SFT-25R. RovyVon states that these are cool white. A excessive CRI model can also be accessible!
Every entrance emitter has just a little easy reflector. These make for a really good beam!
The laser has just a little indicator icon on the facet. It truly is extra to point which change to make use of, because the laser itself comes out from between the white emitters.
LED Coloration Report (CRI and CCT)
The entrance white emitter output is, in truth, cool white. It’s additionally low CRI. The facet white (second row) is way hotter, however nonetheless low CRI.
CCT (Correlated Coloration Temperature) refers back to the measurement of the colour look of sunshine, expressed in Kelvins (Okay), which signifies whether or not the sunshine is heat (yellowish) or cool (bluish). A decrease CCT (beneath 3000K) is taken into account heat mild, whereas the next CCT (above 5000K) provides cooler, bluish mild.
CRI (Coloration Rendering Index) is a measure of how precisely a light-weight supply renders colours compared to pure daylight. Scored on a scale from 0 to 100, increased CRI values point out that colours seem extra true to life and vibrant, just like how they might look beneath the solar.
Beamshots
These beamshots at all times have the next settings: f8, ISO100, 0.3s shutter, and guide 5000K publicity. These images are taken at ground degree, and the beam hits the ceiling round 9 ft away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b model) (affiliate hyperlink)
I hold the take a look at flashlight on the left and the BLF-348 reference flashlight on the appropriate. These images are taken round 18 inches from the door.
I examine the whole lot to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the most effective tint!
Abstract and Conclusion
I discover the RovyVon E10 Professional flashlight to be an fascinating entry into the flat mild world. RovyVon is not any stranger to this class, so we must always anticipate a reasonably mature product line right here.
