Short Review

It’s hard to say what I expected out of the new brand Vezerlezer. Regardless of what you might think, this is a fairly solid offering. I appreciate that the bezel isn’t thread-locked.  The charging works well (despite not working C to C).  Everything about the light is just solid.  The e-switch works well.  Output is great too (if a bit below specification.)  All in all, this is a good first entry into the market. The price is maybe a bit high for starting out, though.

Package and Manual

Build Quality and Disassembly

This spiral design – something we’ve seen before years ago by a brand called Zanflare.  The Zanflare F1 is vaguely similar, in fact.  But there are other brands using the spiral design.

The build quality here is good.  Having used the light as much as I have, I can say that there are some sharp corners.  Not painfully sharp, but sharp such that the anodization will wear fairly quickly.

The silk-screener clearly gets paid by the amount of coverage….

Threads on both the head and tail are anodized and properly lubed. Because of the anodization, it’s possible to lockout the light with minimal loosening of the head or tailcap.

Both head and tail have nice beefy springs.

Here you can see that the cell tube is fully removable. It’s not reversible.

The bezel is easily removable too – there’s no thread-lock here! Interestingly the reflector also screws into the body. I don’t think this is uncommon but I couldn’t tell you the last light I had with a screw-in reflector. It’s neither better nor worse, but it is a nice detail by Vezerlezer.

The bezel being removable does mean that the emitter is highly accessible.

Size and Comps

Length: 112mm
Weight 130g

That’s actually all the official numbers. I’ll add the following

Tail diameter: 24.5mm
Head diameter: 27.06mm
Angled part of head diameter: 28.04mm (~32mm at thickest angles)

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Retention and Carry

The ED10 ships with a friction fit pocket clip attached.

This is a fine clip. When on the tail, it provides a nice deep carry.  The clip can also be placed near the head, but this affords a much shallower, but bezel-up, carry.

Also included is a lanyard, which attaches firmly through the hole in the tailcap.

Since the pocket clip has a hole too, you could attach the lanyard there.  But as it’s a friction fit clip, the tailcap is going to be a better choice.

I am surprised to note that the tailcap does not have a magnet. The tailcap design (specifically the smoothness and large surface) makes me think it would have a magnet, but it certainly does not.

Power and Runtime

A single lithium-ion cell powers the Vezerlezer ED10 EDC flashlight.  Vezerlezer includes the required cell – a button top 18650.

Since the light has springs on both ends, any type 18650 will work fine though. (I’m using a flat top unprotected cell in the light right now, in fact.)

The cell should be installed with the positive end (the button) toward the head.)

In case you forget this orientation, Vezerlezer has included more silk screening to indicate the cell orientation. It’s on the cell tube, but remember the cell tube isn’t reversible, so there’s no problem here.

Here are three runtime tests.  The output does step down from Turbo but not really “all that quickly” – there’s a respectable hold at the higher output level. Unfortunately the output doesn’t seem to be met, at around 1877 max and 1750 at 30 seconds.

Interestingly the runtimes below are quite different – the runtime on High is actually shorter than the runtime on Turbo.  That’s because Turbo steps down to a lower output than High ever is, and so High is effectively run harder than Turbo.

The indicating switch does give information about the cell.  Every time the light is turned on, for 5 or so seconds, the indicating switch will be red, green, or orange with the following associations:
Green: 75-100% power
Orange: 50-75% power
Red: 25-50% power
Red Blinking: 0-25% power

Charging

Vezerlezer put USB-C charging in the ED10 EDC flashlight.  This charge port is covered with an attached, press-in cover.  The cover is nice, but not very stiff.

Also included is a USB to USB-C cable.

Charging looks good, and during the CC phase is very consistent at over 1A.  This is actually very solid charging.

During charging the indicating switch will blink red.  When charging is complete, the switch will indicate in green.

Unfortunately, C to C charging does not work.

Modes and Currents

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens	Tailcap Amps
Turbo	2200	1h22m	1750	6.58
High	1400	2h10m	1140	3.27
Medium	560	3h	509	0.92
Low	128	10h30m	113	0.24
Eco	30	37h	28.3	0.06
Moonlight	1	886h	0.5	8.9mA

Pulse Width Modulation

Every mode uses PWM.  You can note from these graphs below, though, that the PWM is very fast.  In fact, you can take this light as proof that PWM isn’t always annoying.  Fast PWM is ok!

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms.  5ms.  2ms.  1ms.  0.5ms.  0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

There’s just one button on the ED10 EDC flashlight.  It’s an e-switch on the head.

The switch is proud and fairly easy to find by feel.

Also on this switch is an indicating function.  The switch cover feels metal, and has a translucent area in the center to allow the red and green indicator to show through.

Here’s a UI table!

State	Action	Result
Off	Click	On (Mode Memory)
On	Click	Off
Off	Hold	Moonlight (in Discrete) or Eco (In Continuous (Ramping))
On	Hold	Mode advance (excluding Turbo)^ or Continous ramping if in this group
Off	Hold 5s	Output selection style switch (Ramping or Discrete)
Any	Double click	Turbo
Turbo	Click	Previous state
Turbo	Hold	Moonlight
Any	Click 3x	Strobe
Any	Click 4x	SOS
SOS or Strobe	Click	Previous state
Off	Click 5x	Lockout
Lockout	Click 5x	Unlock

^ The direction of advance is dependent on how you got to where you are.  Basically, if the light thinks you want a lower mode, the direction will be from higher to lower output.  Otherwise (the default) will be lower to higher order. This isn’t bad – for example if you’re advancing upward, release (pause) and hold again, you’ll begin the descent in modes.  But if you are advancing upward, turn the light off then turn it back on and hold, the light will continue advancing upward.  This is the logical way, but very hard to tabelize. Technically is’ more specific than that.  If you hold within 1.5s after increasing modes, then the next hold will decrease the modes. Also, the manual indicates that moonlight is not part of the regular mode cycle, but it is.

LED and Beam

There’s a single emitter in the ED10.  It’s a Luminus SST-40 emitter.

This emitter benefits from a reflector that has an orange peel texture and is fairly deep.

LED Color Report (CRI and CCT)

Vezerlezer states the CCT as 6500K but doesn’t state the CRI of this Luminus SST-40. The CCT tests at around 5400 for the lower modes up to around 6600 for the higher output levels. The CRI is particularly not great at around 66.

Beamshots

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

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

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

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

Conclusion

What I like

• Good entry into the EDC flashlight market
• Complete package
• USB-C Charging
• Good user interface
• Very good throw
• Indicating e-switch with a metal cover
• Easy to avoid Turbo if you wish
• Moonlight is part of the main group
• Offers Ramping (or “Continuous”) output (but discrete modes are there, too)

What I don’t like

• Low CRI emitter
• Doesn’t quite hit the specs for output
• Output on any of the modes isn’t flat (ie it fades as cell voltage fades)
