Olight makes some great quality flashlights, and headlamps. But they also have lots of other types of lights like: gun lights, desk lights, tactical lights, high-power lights, general lamps/lanterns, and they even have multiple outdoor products.

This particular model – the Olight Arkfeld Ti – is a new limited edition (not a new version) of the very popular Olight Arkfeld. There are only 5,000 pcs available worldwide. It’s a nicely portable EDC light that is honestly a bit intriguing. It’s pocketable, it’s rechargeable, it’s easy to use, and well… I gotta leave something for the rest of the review so please read on!

Package quality.

Some of the higher-end Olights come in heavy-duty two-part nested containers with splashy images of the light inside and meticulously arranged contents. Other lights, like some of the more EDC models, come in nice, but not overdone, packaging. The Arkfeld came in one of the latter packages. It’s nice, clean, and gets the point across without investing too much in the box. Sliding out the inner, formed plastic tray reveals:

• Olight Arkfeld
• Magnetic charging cable
• Manual

Since Gabriel reviewed the original Olight Arkfeld, I copied parts of his review that were the same.

The Arkfeld is a fairly flat, rectangle-looking flashlight that looks a bit like a tiny remote control. It is a bit slippery, as there is no knurling on the body.

There’s a sturdy clip on the Arkfeld that helps with the grip. It’s held onto the back of the light by a couple of hex-head screws. The clip is very functional and seems to be pretty robust. The tail of the Arkfled is magnetic and can stick to all sorts of ferrous objects.

The switch is a bit interesting. It consists of an outer ring and a center button. The outer ring is referred to as the “selector”, as it allows you to switch between the white LED and a green laser. The ring rotates between two positions, as etched into the body. Point the selector to the left, and you get a green laser beam. Rotate it to the right and you get the white LED output. The ring has two nubs on top that help you to easily rotate it with your thumb. The center button is an e-switch that controls the usual stuff like on/off, mode changes, lockout, etc.

The selector ring sits at about the same height as the center button, so it does give some protection against accidental activations. I had the Arkfeld right in my front jeans pocket for a couple days, and I don’t think it ever activated unintentionally.  So it does seem to help, but there is an easy lockout mode if it gives you trouble.

This light is very much an EDC kinda light. Having 1000 lumens of moderately floody light is good for things like around the house/office, out for a walk, etc. Oh, and that laser? Great for presentations, entertaining your pets, or entertaining your kids that don’t mind pretending to be cats while you play with a laser.

As I mentioned earlier, there is no knurling on the Arkfeld. It’s very smooth all the way around. And the finish? Like any Olight I’ve handled, the build quality feels great. It’s bold, it’s solid, it’s unique… I like it. Most flashlights are pretty boring cylinders with lights at one end. The Arkfeld is a nice change in pace for flashlight design, and I appreciated it when companies think outside the box a bit.

This one, however is built with a titanium housing instead of the aluminum, Gabriel, reviewed.

Warranty:

• The Arkfeld is covered by Olight’s 2 year warranty.
• Within 30 days, contact the original seller for repair or replacement
• Within 2 years of purchase, contact Olight for repair or replacement
• The charging cable is covered for 1 year

Earlier this year, Olight made a pledge to the community to listen to customer feedback. And I think offering CCT options is one of the key ways that Olight is proving this out. The aluminum Arkfeld is offered in both Cool White (5700-6700K) and Neutral White (4000K-5000K) options. But this Olight Winter 3 (titanium) and the Eternal 3 version (copper) are only available in 5700-6700K. The LED version is clearly labeled on the underside of the flashlight. 

It’s a bit tough for me to tell what is all stacked at the front of the Olight Arkfeld. There’s certainly a rounded rectangle of something, but I can’t tell if it’s glass over top of optics, or if it’s just a custom optic. Either way, it’s held in place by a black bezel. As you’re holding it, there is the laser on the left and the right side is occupied by a small TIR optic above a white LED.

I measured with my Opple Light Master at 4 meters on the Turbo setting and at 30 centimeters on Moon setting, and got the following results:

LED measurements Turbo:

• CCT: 6214K
• CRI Ra: 72.0
• DUV:+0.0013

LED measurements Moon:

• CCT: 5892K
• CRI Ra: 69.9
• DUV:+ 0.0042

Both modes have a slightly positive DUV, but it’s hard to see any grean.

Speaking of green… in addition to the white LED, Olight has outfitted the Arkfeld with a green laser. I don’t have any fancy measurement equipment for lasers, so I’ll just mention the specs. This is a Class 1 laser with a maximum output of 0.39 mW.  The wavelength is 510-530 nm. Max runtime is 122 hours.

The UI is pretty standard stuff and easy to get the hang of if you’ve spent any amount of time with an e-switch light:

Available modes: Moon, Low, Med, High, Turbo

Available blinky modes: Strobe

User interface:

From OFF:

• Press and Hold 1 second: Moon
• Press and Hold 2+ seconds: Lockout
• Single click:  turn On
• Double click:  Turbo
• 3 clicks: Strobe

From ON:

• Press and Hold: change modes (Low > Med > High)
• 1 click:  turn Off
• Double click: Turbo
• Double click + hold (press & release, press & hold): activate timer
• 3 clicks: Strobe

Mode memory:

• If you turn the light back on within 1 minute of turning it off in Turbo or High, it will come back on in the High
• After 1 minute of being off, Turbo and High modes revert down to Medium mode
• Moon and Low modes will be completely memorized
• Strobe mode cannot be memorized

Shortcuts:

• To Low: press and hold 1 second from Off
• To Turbo: double click (from Off or On)
• To Strobe: triple click (from Off or On)

Low voltage warning:

• There are four LED spots below the selector ring that display the battery level:
  • 4 green LEDs lit: >75%
  • 3 green LEDs lit: 50-75%
  • 2 green LEDs lit: 25-50%
  • 1 green LED lit: 10-25%
  • 1 red LED lit: <10%
• When turning the Arkfeld on, the indicator lights do a nice sequential ramp up
• After being on for a few seconds, the indicator LEDs turn off (again, in a nice sequential pattern)
• When turning the Arkfeld off, the indicator LEDs turn on again for a few seconds, then turn back off

Strobe/blinkies

• There is a strobe mode that can be activated with a triple click from Off or On

Lock-out mode: 

• Electronic lockout mode is enabled by holding the button down for 2+ seconds while the light is off

PWM

• There is no PWM present

Additional info on the UI: 

• With the selector ring in the laser position, the only UI options are single click Off & On, plus lockout

Olight Time mode

• There is also a neat Timer mode, as seen on other Olights.
  • With the light on and in your desired mode, do a double click + hold (press & release, press & hold) until you see a blink.  
  • One blink means that you activated a 3 minute timer.  
  • Two blinks means that you activated a 9 minute timer.
  • To switch between the 3 minute and 9-minute timers, after you’ve activated the timer, do another double click + hold.
  • Your timer preference (3 minutes versus 9 minutes) will be memorized for next time.

The Olight Arkfeld uses a built-in battery. I don’t see where Olight mentioned the capacity of the battery, but some charging tests showed that about 914 mAh was transferred during charging at 5V. Olight says the charge rate using the supplied MCC (magnetic charging cable) is 1 amp and a charge cycle should take around 2 hours. I tested only about 1 hour and 15 minutes the 2 times I tested this. The charge current is about 0.9A max.

Lux was measured by a Hgner E4-X at 5 meters. Lumens were measured in a homemade integrating sphere with an Extech SDL400 lux meter, and calibrated with a Maukka calibration light. 

Lumen measurements

Note: Olight mentions in the manual that Turbo can only be activated if the battery is over 75%

Aluminum Arkfeld *Cool White version) tested by Gabriel:

Mode	Specs	Lumens @turn on	@ 30 sec	@ 10 minutes
Moon	1 lm	0.8	0.8	–
Low	15 lm	13	13	–
Med	60 lm	54	53	53
High	300 lm > 60 lm	272	271	269
Turbo	1000 lm > 300 lm	877	858 lumens	269

Titanium Arkfeld (Cool White version) tested by me.

Mode	Specs	Lumens @ turn on	@ 30 seconds	@ 10 minutes
Moon	1 lm	1	1	–
Low	15 lm	14	14	14
Med	60 lm	56	56	55
High	300 lm	284	284	282
Turbo	1000 lm	907	875 lumens	279

My measurements were a bit higher than Gabriel, but still a bit lower than Olights specs. This is a little unusual. Olight tends to be pretty conservative with their numbers.

High	126 min + 34 min	2 hr 12 min	2 hr 12 min
Turbo	4 min + 110 min	1 hr 44 min	1 hr 56 min

Mine were a bit shorter than specified.

ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

Peak beam intensity and beam distance measurements

Throw was measured at 5 meters after 30 seconds from turn-on.

Mode	Specified	Candela	Meters	Yards
Moon	–	0	0	0
Low	–	50	14	15
Med	–	175	26	29
High	–	850	58	64
Turbo	2,560 cd	2,725 cd	104 m	114 yd

Lumens were a bit below spec, but throw just a bit above.

Olight Arkfeld Aluminum vs Olight Arkfeld Titanium

Comparing these measurements, both perform pretty close. The titanium version I measured a little higher in output, but shorter in runtimes.

Based on these findings, it’s more of a choice whether you prefer aluminum or titanium. I think the copper version might perform close as well. The Titanium version is also a bit heavier than the aluminum counterpart.

Extra info: Peak beam distance according to ANSI FL1 standards: The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object).

Shot with Canon EOS 5D mk2 with 50mm lens at F4, 1/4 sec, ISO1600. The distance to the shed is approximately 65 meters. The distance to the reflective fence is about 200 meters.

Beamshots compared to the following flashlights:

• Olight Arkfeld, Titanium, Winter 3
• Olight Baton 3
• Olight S2R Baton II
