Package deal and Guide

Construct High quality and Disassembly

The Wurkkos HD03 clip flashlight is stable, like most of those little clip lights are. I don’t assume this one is merely press-fit collectively – I consider there’s at the very least one screw on the again. You’d must take away the clip by some means to get to that screw, although.

Measurement and Comps

60mm x 28mm x 25.2mm and 49g.

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 check mild with the venerable Convoy S2+. The model under 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 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 Complete Tesseract in brass. I really like the Trident, and it’s a hanging distinction to the cheap Convoy S2+, one other nice SRM.

Right here’s the Wurkkos HD03 clip flashlight with an Olight Oclip Professional mild. They’re very comparable in measurement!

Retention and Carry

You may infer primarily based on the identify that it is a clip mild. And it’s! Contained in the opening are a few little grip toes. It’s a helpful clip and would connect properly as a bicycle mild or backpack mild.

The clip is sort of helpful!

There’s a magnet too.

A few lanyard choices are included.

You possibly can connect these in any variety of methods, together with utilizing them collectively for a quick-release state of affairs.

Energy and Runtime

Wurkkos says the built-in battery is a 600mAh LiPO. I don’t know how you can entry this battery, although.

Beneath you’ll be able to see the runtimes of some modes for each white lights.

The change signifies the final battery stage. It does so whereas working (for just a few seconds after being turned on), and the change signifies as follows:

Inexperienced: 50-100% energy
Orange: 20-50% energy
Crimson: 1-20% energy

The temperature traces in these charts are included as basic 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 connected nonetheless possible and never at all times on the bezel or hottest spot (assuming that may even be clearly outlined). Even with best placement, too many variables have an effect on temperature to definitively state a particular max worth.

Charging

After all, with a built-in battery, there have to be built-in charging. I’m happy to say that charging is by the use of a USB-C port on the prime of the head.

Wurkkos additionally gives a USB-C to USB-C charging cable.

Charging by way of both C to C or A to C works simply high quality and takes round an hour and a half.

Modes and Currents

Pulse Width Modulation

Every mode makes use of PWM. A few of it’s not fast, and also you’re prone to discover it.

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 below are a number of timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make evaluating this “worst” PWM mild to the check mild simpler. That submit additionally explains why I didn’t check the WF-602C on the common 50us scale.

Consumer Interface and Operation

The Wurkkos HD03 clip flashlight options an e-switch on the facet of the top. The metal-covered change has an indicator within the heart. It’s indicating in inexperienced, under.

I discovered that at instances, the change cowl would possibly get angled such that it could actually stick under the sting of the physique. It’s simply manageable, however annoying.

Right here’s a consumer interface desk! Reverse the e-switch is a selector change. Utilizing this, you might choose between flood and throw. The consumer interface for flood and throw is identical, which is good.

^ The handbook has this improper – it states that double clicking goes again to the earlier state. Double clicking from Turbo simply goes again to Turbo, although.
^^ The handbook describes this as “stepless dimming” nevertheless it’s not dimming, it’s advancing by the RGB choices (in a stepless manner.)

LED and Beam

Wurkkos doesn’t state what emitters are used right here. The flood emitters are behind a dimpled TIR and the spot emitter has a extra customary TIR for good throw. Beneath you’ll be able to see traces throughout this TIR, too, and sure, that does have an effect on the beam profile. It’s kind of a “bicycle” profile.

LED Shade Report (CRI and CCT)

The throw emitter is cool white and low CRI, however I’m pleased to report that the flood emitter is each impartial white and excessive CRI!

CCT (Correlated Shade 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 (under 3000K) is taken into account heat mild, whereas the next CCT (above 5000K) provides cooler, bluish mild.

CRI (Shade Rendering Index) is a measure of how precisely a lightweight 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, 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 handbook 5000K publicity. These images are taken at flooring stage, and the beam hits the ceiling round 9 toes away.

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

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

Abstract and Conclusion

This mild is on sale now for round $18 and that’s a fairly unimaginable worth. I do suggest grabbing one. If nothing else, the RGB choices (of which there are numerous, and lots of of these are very attention-grabbing) can be enjoyable for youths! Charging works nice, and I really like that the flood emitters are excessive CRI.

The Massive Desk

^ Measurement disclaimer:  Testing flashlights is my interest. I take advantage of hobbyist-level tools 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 cheap.

What I like

• Construct high quality
• Very low price
• Attention-grabbing RGB choices (unsure I’ve seen all these mixes earlier than!)
• Excessive CRI flood emitters
• USB-C charging works effectively

What I don’t like

• Inexperienced throw emitter
• Beam profile shaper for throw channel
• E-switch cowl will get caught sometimes
