Package deal and Handbook

Construct High quality and Disassembly

The LoopGear SK-05 Professional flashlight may be very very similar to the LoopGear SK-05 (non-Professional). There are just a few variations, most of that are essential later within the assessment. However common construct high quality is identical between fashions – superb.

In fact, one of many greatest variations is that the cells are accessible! So inside the sunshine, you may see that the optimistic contact is a giant button.

And the opposite finish, the place destructive contact is made, there are twin springs.

Dimension and Comps

106mm x 47.8mm x 22.5mm and 235g. Notably, this is identical measurement because the non-Professional. (And 10 grams heavier.)

If the flashlight will headstand, I’ll present it right here. If the flashlight will tailstand, I’ll additionally present that right here too!

Right here’s the check gentle 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!

Within the photograph above, you could be aware that the SRM (customary reference materials) flashlight for comparability has modified! I used a TorchLAB BOSS 35 for ages. Now what you may see because the 18350 SRM is the Hanko Machine Works Trident. 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 like the Trident, and it’s a putting distinction subsequent to the cheap Convoy S2+, which additionally makes a terrific customary reference materials.

Retention and Carry

Not like the non-Professional, there’s a pocket clip included right here. It’s not hooked up, however two screws (and two additional) are included. A screwdriver (TORX) can also be included, too!

Somewhat sticky sticker is included. The handbook doesn’t say the place it goes, neither is there any actual instruction on methods to set up the pocket clip. However it’s not exhausting to grasp.

I consider the clip is shaped in order that it might be put in in both course. Reverse to how I’ve it under is likely to be higher, and permit a deeper carry.

There’s a powerful magnet within the tailcap. It’s completely adequate for holding the LoopGear SK-05 Professional flashlight horizontally or vertically.

In the identical tailcap space, there’s a loop the place a lanyard might be hooked up, however no lanyard is included.

Energy and Runtime

The LoopGear SK-05 Professional flashlight makes use of two 18650 cells. The 2 which might be included are 4000mAh customary 18650 cells.

The cells go into the sunshine with the button (optimistic finish) towards the pinnacle. They’re parallel, too, so that they each go in the identical course. This does imply that the sunshine can run with only one cell!

Right here’s the little lever the place you may entry the hinged cell cowl. There’s a lock swap for this cowl, too.

Runtime checks are under. I examined the upper two modes with each sorts of output (spot and flood). I didn’t check the output with each emitters, although. I don’t consider the handbook makes any declare about that output degree.

The sunshine shuts off with low voltage safety. There’s a distinguished facet RGB COB that alerts the person to the approximate cell voltage at startup. Actually, you don’t even have to show the sunshine on – simply swap the rotary dial away from lockout mode, and the indicator will show the cost degree. It’s principally an influence meter. Purple means principally empty (“0%”), and something blue is greater than that. So, for instance, if the indicator is half blue and half off, the cost is roughly 50%.

Charging

UBS-C charging is used for the Loop Gear SK-05 Professional flashlight. The port is close to the pinnacle and has a press-in silicone cowl.

A C to C charging cable is included.

Charging seems to be nice – Whereas C to C delivers much less present, it’s delivered at 12V, so is total a lot faster. A to C additionally works nice, however at 5V and the next present nonetheless takes over 3 hours.

The RGB COB on the facet signifies the charging standing.

Powerbank

The LoopGear SK-05 Professional flashlight is able to getting used as a powerbank. Under you may see the facet markings – the sunshine will be charged at 5, 9, or 12V, and can even output (powerbank) at 5, 9, and 12V.

I examined the powerbank solely at 5V, nevertheless it appears to carry out simply nice.

Output proceeds at round 3.3A for over an hour. At that time, the powerbank is principally depleted (round 3V) nevertheless it’ll nonetheless output at decrease currents for a short while.

Modes and Currents

Pulse Width Modulation

Solely the highest mode for every output makes use of PWM. That’s putting. The off-cycle may be very transient although, so it’d be almost unattainable to note this PWM.

Right here you may see a “baseline” – a chart with nearly no gentle 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 gentle to the check gentle simpler. That submit additionally explains why I didn’t check the WF-602C on the ordinary 50us scale.

Consumer Interface and Operation

There are two methods to work together with the Loop Gear SK-05 Professional flashlight. First, there’s a rotary dial. It has 4 positions. Locked (seen under), flood, spot, and facet RGB.

Subsequent is the e-switch, proper within the middle of that rotary dial. It’s a really huge swap with good motion.

As said above, there’s a rotary dial with 4 positions. You’ll wish to rotate this dial to your output of alternative, then comply with the actions within the person interface desk under! Notice that the person interface for Spot and Flood appears to be the identical.

One replace to this Professional model is that there appears to be a delay. That is most likely to stop unintended activation. So in each case, the dial might want to have been rotated earlier than the e-switch will work.

Numerous clicks can carry out varied issues for the RGB ranges. Suffice to say that the RGB choices are drastically elevated for the Professional model. You may velocity up the biking of some RGB choices. Most of the RGB choices have low/medium/excessive, too. It’s fairly spectacular!

Loop Gear SK-05 Professional Flashlight LED and Beam

There are two choices right here for output. Within the photograph under, the left emitter is the “Spot” output – it’s a Luminus SFT25R. The triple on the correct are three Nichia 519a emitters.

The facet emitters are RGB, together with three variations of white.

LED Colour Report (CRI and CCT)

CRI and CCT will not be mysteries – LoopGear claims the Nichia triple to be 5700K, and that’s roughly proper – I measure it as 5500-5900 CCT. CRI may be very excessive, at above 97. That’s superb! 

The center row is the spot emitter – CCT is cool or very cool, and CRI is low.

The final row is the facet heat white. I didn’t check Impartial or Cool for this facet emitter array. These are very uncommon, in that they’re heat white and very low CRI. Probably the bottom CRI I’ve ever noticed on a “white” emitter.

CCT (Correlated Colour 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 gentle, whereas the next CCT (above 5000K) offers cooler, bluish gentle.

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

Beamshots

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

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

I maintain the check flashlight on the left and the BLF-348 reference flashlight on the correct. 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 very best tint!

Abstract and Conclusion

The LoopGear SK-05 Professional flashlight is unquestionably a step up from the unique (or “non-Professional”) SK-05. Having replaceable batteries alone is sufficient to make this one higher. Energy Ship output from the powerbank is a standout function, too! I like all of the RGB output adjustments, and that there are three CCT from the facet white. It might be good if the sunshine labored whereas charging. This can be a nice enchancment from the unique, and a strong gentle, too.

The Huge Desk

^ Measurement disclaimer:  Testing flashlights is my passion. I take advantage of 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 specific amount of distinction (say, 10 or 15%) is completely affordable.

What I like

• Strong construct high quality
• Cells are simply accessible
• Makes use of customary flat-top cells
• Intuitive person interface
• RGB facet choices are enjoyable!
• C to C charging works very effectively
• Can run off only one cell
