Vezerlezer WK2 Flat Flashlight Assessment

The Vezerlezer WK2 flat flashlight is touted as an “All-in-1” flashlight. It has a excessive CRI entrance and aspect (COB) output, a inexperienced laser, and ultraviolet. Learn on!

Official Specs and Options

Right here’s a referral hyperlink to the official product web page.

Variations

The Vezerlezer WK2 flat flashlight is on the market in six physique colours: Black, Inexperienced, Gray, Blue, Purple, and Orange. I imagine the internals are the identical for all variations (however extra on that beneath.)

Worth

The Vezerlezer WK2 flat flashlight is barely obtainable by way of Kickstarter proper now, and as with all Kickstarters, the value varies based mostly on the tier. The very least costly tier is round $17, which is a loopy (low) worth!

What’s Included

• Vezerlezer WK2 flat flashlight
• Charging cable

I don’t imagine that is the retail bundle, so reference the Kickstarter to see what it’s best to actually anticipate. On the very least, I’m certain you’ll get a guide, too.

Package deal and Handbook

I didn’t get a printed guide. (I did obtain directions electronically, although.)

Construct High quality and Disassembly

The Vezerlezer WK2 flat flashlight has a pleasant construct high quality. It’s not distinctive, however it’s positively not unhealthy in any respect, both. For the intro worth of $17, the construct in all probability might be thought-about distinctive!

I didn’t disassemble the sunshine in any respect, however there are two Philips screws on the tail that seemingly permit the interior slide proper out.

Dimension and Comps

L: 34 mm (1.34 in) | W: 19.8 mm (0.78 in) | Total Size: 118 mm (4.65 in).

Right here’s the sunshine in hand:

Right here’s the take a look at mild with the venerable Convoy S2+. It is a brass model, which is an efficient bit heavier than aluminum, however has the identical dimensions: 24mm in diameter by 117.5mm in size.

Additionally within the photograph above, my Customary 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 Whole Tesseract in brass. I really like the Trident, and it’s a placing distinction to the cheap Convoy S2+, one other nice SRM.

Retention and Carry

The Vezerlezer WK2 flat flashlight incorporates a large pocket clip. It’s very pleasant – a clean, flat physique of the WK2 and a giant mouth on the pocket clip permit the sunshine to slip proper onto a pocket.

It’s a deep carry clip, too.

The tail finish has a moderately sturdy magnet. It’ll maintain the sunshine however gained’t permit a lot jarring.

Above, chances are you’ll be aware a brand new holder for my magnetic-tailcap objects. That’s the Exceed Designs Hyzer Titanium Mini Hatchet D2 axe. The deal with (because the identify suggests) is titanium. However the blade is D2 metal and excellent for retaining magnetic tailcap flashlights! The Hyzer is on the market in a bunch of cerakote physique colours in addition to completely different thickness D2 heads.

Energy and Runtime

I don’t see any assertion about what capability LiPO is used within the Vezerlezer WK2 flat flashlight. No matter it’s, it’s not accessible, and whereas it might be technically attainable to alter it, you’ll must have more-than-consumer-level abilities to do that.

Relating to the “extra data on that beneath” within the Variations part: I don’t see wherever that Vezerlezer has said completely different variations, however it’s very clear that I received a heat and excessive CRI model. That’s improbable, and I’m more than happy with the high-CRI-ness of this. However it does imply that the specification of “1300 lumens” vs what you see right here could also be complicated. The upper output model will likely be a lot cooler white and doubtless low CRI. However it’ll in all probability come a lot nearer to 1300 lumens than the nice and cozy, excessive CRI model does. And that’s all wonderful, it’s a superbly acceptable tradeoff. It simply must be talked about within the documentation.

The temperature traces 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 actual readings. A temperature sensor shouldn’t be all the time hooked up to the bezel (and even the most well liked spot, assuming that might be outlined). Even with very best placement, too many variables have an effect on temperature to definitively state a selected max worth.

Charging

The Vezerlezer WK2 flat flashlight gives USB-C charging. There’s a press-in cost port cowl. It’s acceptable and feels as safe as most covers of this kind.

A USB to USB-C cable is included.

Charging through A to C or C to C works wonderful. It’s very constant and good high quality charging, however gradual.

Modes and Currents

Pulse Width Modulation

Each mode besides the very best (each entrance and aspect) makes use of 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 a few of the worst PWM I’ve seen. It’s so unhealthy that I used a submit about it to clarify 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 Vezerlezer WK2 flat flashlight has two e-switches. There’s an indicating arrow on every, which demonstrates which emitter(s) it controls.

They’re pretty good switches and have good motion.

Right here’s a consumer interface desk! All of the output choices can work on the similar time aside from two combos: the entrance white LED and UV, and the aspect purple and aspect white. Each different combo appears to work independently of each different choice. This implies you’ll be able to have entrance and aspect LEDs on on the similar time. Or entrance LED and Laser. On and on.

Due to this, the desk is a little bit uncommon. As a substitute of claiming what state the sunshine IS in, it’s clearer to say what state it’s not in. So “entrance LED off” means solely that – every other state could also be lively, however the motion will override (or complement) that.

There’s likelihood I missed a function or two right here.

LED and Beam

I can’t see wherever {that a} declare is made on what emitter is used right here. Each the white LED and UV have a TIR optic.

The aspect COB is an opaque cowl.

It has each purple and white outputs.

Once more, many of the outputs could be on concurrently – within the photograph beneath, you’ll be able to see aspect white and entrance white on on the similar time. I simply examined, and you’ll have the laser on on the similar time, too.

LED Shade Report (CRI and CCT)

The entrance emitter has a very nice 3600K excessive CRI emitter. Aspect white is surprisingly only a bit cooler however nonetheless heat, at round 3800K. It’s additionally excessive CRI. Each are superb!

CCT (Correlated Shade Temperature) refers back to the measurement of the colour look of sunshine, expressed in Kelvins (Ok), 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 a better CCT (above 5000K) provides cooler, bluish mild.

CRI (Shade 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, greater CRI values point out that colours seem extra true to life and vibrant, just like how they’d look underneath the solar.

Beamshots

These beamshots all the time have the next settings:  f8, ISO100, 0.3s shutter, and guide 5000K publicity. These photographs are taken at flooring degree, and the beam hits the ceiling round 9 toes away.

Tint vs BLF-348 (KillzoneFlashlights.com 219b model) (affiliate hyperlink)

I maintain the take a look at flashlight on the left and the BLF-348 reference flashlight on the fitting. These photographs are taken round 18 inches from the door.

I evaluate all the things to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the perfect tint!

Abstract and Conclusion

If you happen to go soar on the introductory or most cost-effective tiers of Vezerlezer WK2 flat flashlight on Kickstarter, you’ll be getting a deal. I like to recommend the sunshine, at round $20! Particularly if yow will discover get this excessive CRI model (for those who’re comfortable with the decrease general output). All the pieces works because it ought to work, and the consumer interface is intuitive sufficient. Charging is nice. Even being gradual might be good for battery life. I didn’t point out this above, however the laser (3R) is very highly effective, too!

The Massive Desk

^ Measurement disclaimer:  Testing flashlights is my interest. I exploit hobbyist-level tools for testing, together with some I made myself. Attempt to not get buried within the particulars of producer specs versus measurements recorded right here; A certain quantity of distinction (say, 10 or 15%) is completely cheap.

What I like

• Low price
• Heat and Excessive CRI output
• Consumer interface (I like that the outputs appear pretty impartial, even when this does imply you’ll be able to flip them on with overlap, unintentionally.)
• Charging works very constantly

What I don’t like

• UV (Simply private desire – for those who like, need, or want UV, then there aren’t issues with the UV right here.)
• Constructed-in battery
