Bundle and Handbook

Construct High quality and Disassembly

The construct high quality is ok. It is a massive mild, although. Perhaps not “massive for a 21700 mild,” (but in addition a bit massive for a 21700 mild.)

Solely the tailcap is detachable, and it’s a bit onerous to take away. The grip that’s current isn’t all that helpful. The threads are unanodized and clean sufficient. It will possibly’t be locked out mechanically due to these unanodized threads!

Measurement and Comps

28mm x 138mm and 176g (with cell)

If the flashlight can headstand, I’ll present it right here. If it could actually tailstand, I’ll additionally present that right here!

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 put up 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 Commonplace 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 hanging distinction to the cheap Convoy S2+, one other nice SRM.

Retention and Carry

There’s a beefy belt clip that attaches solely to the tail finish of the Wuben L3 flashlight.

A lanyard can also be included, and it attaches by these two holes within the tailcap.

Energy and Runtime

Wuben features a 4800mAh 21700. It’s an ordinary button high.

The cell goes into the L3 with the button (constructive) towards the top. For those who overlook that, you possibly can take a look at the little icon on the physique.

Beneath are a couple of runtime checks. So far as I may inform, Turbo is momentary-only. So every time you see a blip to excessive output, that’s me holding the button down once more.

Perhaps curiously, however when Turbo fades (in all probability due to temperature regulation), it’s going to fade to output decrease than excessive. For those who had been beforehand on excessive, and launch the swap, the sunshine will return to (aka improve to) excessive. You may see that in a lot of spots beneath. Output reaches near-Turbo ranges very often as soon as the sunshine has cooled down. I ended the take a look at manually – the sunshine would have continued with repeated presses of Turbo or stayed at another degree. However the level was to see what Turbo does.

The temperature traces in these charts are included as common context, not exact measurements. The values symbolize the vary (min to max) throughout testing, however shouldn’t be taken as precise readings. Temperature sensors are hooked up nonetheless possible and never at all times on the bezel or hottest spot (assuming that may even be clearly outlined). Even with supreme placement, too many variables have an effect on temperature to definitively state a selected max worth.

Charging

The Wuben L3 flashlight makes use of USB-C for charging. There’s a neat screw-down cowl over the charging port.

Wuben features a USB-C to USB-C charging cable, too.

Charging is labeled as “quick” as a result of the C to C can cost at 12V. 12V at round 1.4A or 5V at round 2.6A. Both means it’s fairly quick, at round 2 hours. Additionally this must be high quality for the cell, because it’s an enormous 4800mAh.

Modes

Pulse Width Modulation

The bottom two ranges have a little bit of disturbance. I’m unsure that that is PWM, although.

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 number of the worst PWM I’ve seen. It’s so unhealthy that I used a put up 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 put up additionally explains why I didn’t take a look at the WF-602C on the common 50us scale.

Person Interface and Operation

There’s only one button for controlling the Wuben L3 flashlight. It’s a two-stage e-switch on the tail.

Right here’s a consumer interface desk!

^ Successive clicks by the modes don’t cycle “Moon > Low > Med > Excessive > Moon” (as you’ll count on, and as you might be used to.) They Cycle “Moon > Low > Med > Excessive > Med > Low > Moon > Low” which makes it onerous to know the place you might be and the place you’re going to land.

LED and Beam

The Wuben L3 flashlight makes use of a Luminus SST70 emitter. It has a clean reflector.

LED Coloration Report (CRI and CCT)

The CCT is surprisingly toward-neutral right here, from round 5200 to round 5700K. CRI is (very) low, although, and the Duv is (very) constructive, too.

CCT (Correlated Coloration 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 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, greater CRI values point out that colours seem extra true to life and vibrant, much like how they might look below the solar.

Beamshots

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

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

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

I evaluate the whole lot to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the very best tint!

Abstract and Conclusion

The Wuben L3 flashlight is a vivid mild and it does provide quick charging! Output doesn’t appear to hit the claimed 3000 lumens, and whereas I don’t love the momentary-only Turbo, it does hit near-initial output after cooling down. That’s spectacular! The sunshine can also be not simply starkly cool white, which is a reduction.

The Huge Desk

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

What I like

• Not cool white
• Excessive output
• Quick charging (12V)
• Two-stage e-switch

What I don’t like

• General measurement
• Low CRI
• Mode advances up then down then up
