RovyVon has a new rectangular light out.  It first came out with side UV-C, which wasn’t interesting at all, but now the side lights are NW Cree XP-G3.  So RovyVon sent this one over for review and testing.  Read on for photos and thoughts!

Official Specs and Features

Here’s a link to the official product page.


There are three versions of the E200.

The E200u uses a dual-chip LED which makes UV-C (270nm) and UV-A (390nm-400nm).
The E200s uses CREE XP-G3 LEDs for both front and sidelight (Front is 6500K and Side is 5000K for color temperature).
The E200r has red and blue LEDs for the front light and CREE XP-G3 LEDs for the sidelight.


These are listed at $79.95 right now on amazon (referral link).

Short Review

This is another neat little light from RovyVon.  I like the size better than the bigger angel eyes E300s, and overall it’s probably more useful.  Charging is fast and consistent.  Output is a lower than spec.

  • Measurement disclaimer:  I am an amateur flashlight reviewer.  I don’t have $10,000 or even $1,000 worth of testing equipment.  I test output and such in PVC tubes!!  Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

What’s Included

  • RovyVon E200s Flashlight
  • Pocket Clip
  • Lanyard
  • Charge cable (USB to USB-C)
  • Manual and papers

Package and Manual

Build Quality and Disassembly

Build quality is good.  The guts are both sandwiched and screwed into the inside.  The light will not lay flat on any side except the switch side for the front emitters.  This is a minor annoyance (but still an annoyance).

The battery was on 25% when I took these photos.  Normally that isn’t lit, of course.

I was surprised to find that the side emitters operate 1-2-3 for the three modes.

The front emitters are not this way, and operate together in every mode.

The whole light is held together by these two Torx screws.  They are T6 size.  They remove easily (no Loctite.)

The back removes easily after the screws are removed.  Even when unscrewed, there’s not much of a gap for pulling off the cover.  I got a thumbnail under the pocket clip holder, and lifted it up pretty easily.  (It’d be even more easy if the pocket clip was installed – just grasp the pocket clip and pull up).

Note the two magnets just inside the two screw holes there.


The reflectors for the front emitter look to have a bit of epoxy.  I am unsure how this would complicate emitter swaps for this light.

When reinstalling the back plate, you’ll need to get these two little nubs seated, and then just lay the back down for a seal, and replace the screws.

Size and Comps

The size is 79.8mm x 33.8mm x 17.5mm and 2.89oz.

Notably it’s much smaller than the E300.  Width is about the same, though.

Retention and Carry

A pocket clip is included.  It attaches on the back of the light.  It’s a sort of “slip on” clip.

Installing it isn’t the easiest prospect, but if you will lay it as seen below, and press fairly hard right where my index finger is, you’ll flex the clip enough for it to grab the rails.

The clip will fit in either orientation.  Also it doesn’t really “click” in or anything, it just stays in place with friction.

Also included is the lanyard, which attaches on the back (bottom?) of the light.

Also on the same end as the lanyard hole (above, above), is a tripod hole.

The tail end has magnets too.  They can be seen from the disassembly photo:

These magnets will hold the light, but they aren’t all that terribly strong.  They do hold the light fairly well.

The clip being reversible does mean this light is useful as a hatlight.

Power and Runtime

The E200 is powered by a built in 1400mAh LiPO pouch.  It looks to be hard wired, but at the least it is accessible easily.

Here are a couple of runtimes for the front emitters.  I wasn’t able to determine LVP.  When the light is at the end of a test, all modes are accessible, but they are much lower than usual output.  So it’d be very unlikely you wouldn’t notice the battery needs to be charged.  And of course there’s the warning on the side.

Here are two runtimes for the side emitters, too.  Output is much lower than specification for the side lights, but it’s more difficult to completely capture the light from them.  I will say whatever their output, they are quite bright.

Here’s the battery indicator.  Four rubber dots, each representing a quarter charge – 25%, 50%, 75%, and 100%.  Below red is lit for 25%.  (This one can indicate red or blue, in fact).

A cable is included – USB to USB-C.

The charge port has a press-in cover.  It’s good enough.

Charging takes under an hour, and proceeds at or around 2A.  While charging the battery indicators cycle flashlight.  When the light is charged, they are all solid blue.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo (front) 1650 2.8h 1152
High (front) 700 4h 548
Mid (front) 150 8h
Low (front) 10 24h
High (side) 800 4h 491
Mid (side) 300 8h 171
Low (side) 5 96h

Pulse Width Modulation

Low and Turbo do not exhibit PWM.  Medium and High exhibit a sort of sawtooth, but it’s not really PWM, and also not at all noticeable.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  And here’s the worst PWM light I have ever owned.  Also one of the very first lights I ordered directly from China!

User Interface and Operation

There are two switches on the E200s.  The first switch, which is on the same side as the side emitters, controls the front emitters.  This one is officially called “Button 1” (and so that’s how I’ll call it, too.)

The other switch is exactly the same size and shape, and is on the narrow side of the light.  This switch controls the side emitters, and is officially called “Button 2.”

It might not be immediately easy to remember which button works for which emitters, but just remember:  Using Button 1 puts your finger in a place to cover the side emitters, so that’s not the button to use for the side emitters.

Also the UI between the two is very similar.

Here’s a UI table!

State Action Result
Off Click Button 1 (B1) or Button 2 (B2) Battery Check
Off Hold B1 Starts on Mid (ish) and enters ramping option.  Will ramp up and down.
Off Double Click B1 On (Memorized Mode (any mode the light has been on for >1m)).
On, Front (From ramping) Click B1 Off
On, Front (From Double Click) Click B1 Mode Advance (LMHT direction)
On, Front (From Double Click) Hold B1 Off
Off Triple Click B1 Strobe
Strobe, Front Click B1 Strobe advance (Strobe, SOS)
Strobe, Front Hold B1 Off
Off Hold B2 Momentary High (Side)
Off Double Click B2 On (Side, Low)
On, Side Click B2 Mode advance (LMH)
On, Side Hold B2 Off
On, Either Double Click No action
On, Either Click “Other” button Light works per that other button’s UI and emitters

LED and Beam

There are 5 emitters in the E200s.  They’re all Cree XP-G3.  These two seen below are the “Front” emitters and always operate concurrently.  These front emitters are 6500K – cool white in fact.

The other emitters are also Cree XP-G3, but they’re NW at 5000K.  These are much better to my tastes.

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Front, 6500K:

Side, 5000K:

Tint vs BLF-348 ( 219b version) (affiliate link)

Test light is on the left!

Front: 6500K:

Side: 5000K:

I compare everything to the 219b BLF-348, because it’s inexpensive and has the best tint!


What I like

  • Dual switches
  • Ramping UI is a nice touch
  • 5000K side lights
  • Versatile UI

What I don’t like

  • 6500K front emitters
  • Non replaceable battery
  • Won’t lay flat
  • Side emitters are under a permanent lens which will scratch because of exposure
