Olight Arkfeld Pro EDC Flashlight Review

The Olight Arkfeld Pro EDC flashlight is both versions of the old Arkfeld! The Pro still has a white emitter but offers both laser and UV in one package, too!

Official Specs and Features

Here’s a referral link to the Olight Arkfeld Pro EDC flashlight product page.

Versions

At least three versions are available right now – Black, Orange (seen here), and Zombie Green. Black is available in neutral and cool white. Orange and Zombie green are only in cool white.

Price

The Olight Arkfeld Pro EDC flashlight comes in at an introductory price ($30 off!) of $69.99. This should take anyone who was on the fence needing both a laser and UV but not wanting two lights. Now you can have both in one great package!

Short Review

I liked the Arkfeld just fine. This one is better. I never need a laser, but I need UV even less. So to have both in one package is super convenient, even if I’ll only ever use the white emitter. As far as the white goes, this Arkfeld Pro is (still) very much a flat-shaped Baton, and I love batons. The Olight Arkfeld Pro EDC flashlight is a high-quality product!

^ Measurement disclaimer:  Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

Package and Manual

Build Quality and Disassembly

The Olight Arkfeld Pro EDC flashlight has a very vapey feel… Maybe that’s just my opinion. That doesn’t take away from the light, though – the Arkfeld Pro has a very robust feel. It’s solid.

One thing you might not notice right away – this Pro version is noticeably larger than the non-Pro. That’s not bad at all. But since the light is essentially just scaled up, it’s easy to miss that it’s larger. (In fact, I didn’t even realize it was larger until I held the Pro and not-Pro side by side.)

Of course, there’s no cylindrical cell in there to rattle around or be removed, or whatever. The cell is 100% built-in. That’s good and bad of course. Building the cell in means Olight can get reliable performance, but it also means you can’t change the cell when it wears out in a number of years.

Whatever the case about the battery, the build here is great. I love the very anti-roll shape. Not only that, but the Olight Arkfeld Pro EDC flashlight slips into the pocket where I normally carry an 18650 light in a much more comfortable way. It’s approximately the same width as my wallet, depending on if I’m carrying my American Express Centurion Card or not.

Having already disassembled my brown non-Pro version, I did not do so for the Orange Arkfeld Pro version. You’re invited to check out the photos from that review, though.  Here’s a link. (Note: I didn’t get too far with disassembly.)

Size and Comps

Weight: 3.92 oz (111g) (Battery Included)
Height: 0.63 in (16 mm)
Length: 4.72 in (120 mm)
Width: 1.06 in (27 mm)

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

Here’s the test light with the venerable Convoy S2+. The version below is a custom laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full post on an engraved orange host right here! Or go straight to GadgetConnections.com to buy your Convoy S2+ now!

Also above is the light beside a new standard 18350 light! It’s not one I’ve reviewed yet but this is the CWF Arcadian Peanut in aluminum. This one is stonewashed and has the new Quantum Dragon driver – a whole new product! Stay tuned for a full review of this tiny powerhouse!

Below you can see the Olight Arkfeld Pro EDC flashlight (left) beside the previous Arkfeld. Again, the Pro is bigger, but I bet you’d never notice it if you didn’t have them side by side.

Retention and Carry

The Olight Arkfeld Pro EDC flashlight gets the updated pocket clip, which is so much better than the first edition Arkfeld clip. This clip allows great deep carry, as well as having a two-way option. I don’t care at all about the two-way, but I love the deeper carry.

Not only that, but this clip also offers a hole suitable for a lanyard! Two advancements in one clip!

The only other way to retain the Arkfeld Pro is with the magnetic base. While mostly for charging, the magnet is strong enough to hold the light in place, too.

Power and Runtime

Olight states this as a “Built-in 1500mAh Lithium Polymer Battery” and that’s perfectly logical. I was unable to gain any access to the LiPO but did run a couple of output tests. There is a battery indicator below the switch and it indicates when the voltage is low. The light finally shuts off, too.

Below you can see the battery indicator – two green indicators in this case.

Charging the Olight Arkfeld Pro EDC flashlight

There’s also onboard charging, by way of a magnetic charge base and a magnetic charge connector in the tail (both parts are magnetic!).  The charging base is the common Olight MCC.

Charging looks pretty good. The max rate is around 0.9A. I would guess the LiPO could handle way more, so I’d love to see this utilize the full capability of a MCC charger.

Notably, this Pro version does not have the “intermittent” or drop-out charging that some of the previous versions had. It also charges more quickly and has a “firmer” cutoff point, too. All of those are very good improvements.

Modes and Currents

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens
Turbo	1300-420	4m-126m	1240
High	420-100	135m+12m	392
Med	100	9h45m	102
Low	15	55h	15
Moon	1	11d	0.99

Pulse Width Modulation

Nothing really to mention here.  None of the modes seem to be using PWM.

Here you can see a “baseline” – a chart with almost no light hitting the sensor. Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.

User Interface and Operation

There’s just one e-switch on the Olight Arkfeld Pro EDC flashlight. Surrounding that e-switch is a selector knob of sorts, which points to either white LED output, ultraviolet, or laser output. Functionally this is exactly the same as previous Arkfelds, but just with one added output option.

The e-switch isn’t proud at all. The selector has one nubs that help flip between outputs.

All of that said, the user interface is basically the same as the Olight S2R Baton II, which I’ve covered before.

When you turn the light on, these indicator LEDs briefly indicate what the general charge state is.

Here’s a user interface table! This only applies when the selector is in the LED position. For ultraviolet output, the switch is simply on/off.

State	Action	Result
Off	Click	On (mode memory)^
On	Hold (release at desired mode)	Mode cycle (L, M, H) (no Moon or Turbo)
Off	Hold	Moonlight
Any	Double click	Turbo
Any	Triple click	Strobe
Strobe	Click	Off
Strobe	Hold	Previous Mode
Off	Long hold (past Moonlight)	Lockout (indicated by a single red line on the battery indicator)^
Lockout	Hold	Unlock to Moonlight
On	Click then Click and Hold (quickly)^^	Timer (Single blink: 3 minutes, Double blink: 9 minutes)
Timer	Click then Click and Hold (quickly)^^	Switch between 3- and 9-minute timers.

^ Moon, Low, Medium, and High are memorized.  Turbo is memorized as High.
^^ The manual states this as “Double click and hold” but I think “Click then Click and Hold” quickly.  Any form of double click ends in Turbo or Strobe.

LED and Beam

Olight doesn’t state what emitter is in the Arkfeld Pro EDC flashlight. I would guess it’s an Osram P9, but it doesn’t matter too much since we’ll see a characterization of the emitter below.

The emitter is in a small TIR, and beside that is a ultraviolet emitter. In the middle (at the bottom in the photo below) is the laser output.

Olight does state what the emitter CCT for this cool white light is though: 5700K- 6700K.

This is the 3R laser version, but I believe some markets may get a different (possibly less powerful) laser. I am not sure how you’d be able to check, but probably start with your local laser laws.

LED Color Report (CRI and CCT)

The CCT claim is 5700K to 6700K and this emitter just about hits that mark. I measure it between 5700K and 6400K. The CRI is mid to low, at around 72. More disappointingly though, is that the Duv is well above the BBL, demonstrating that the output is a bit greenish.

Beamshots

These beamshots always have the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.

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

• Interesting shape!
• Good output
• Meets throw specifications
• The ultraviolet option is neat (and also easy to avoid)
• User interface will be very familiar to anyone with a Baton
• Slips into “the 18650 spot” in a pocket with more comfort than an 18650 light
• Combining these two secondary output options is a very good move on Olight’s part

What I don’t like

• Very floody
• Mid to low CRI
• Non-replaceable battery
• Proprietary charging (seriously, USB-C would be fantastic!)
