Overview
The Olight Arkfield Pro is a rather unique torch. The first thing you notice is its mostly flat design. But it also has three emitters: a 1300 lumens white LED, a green laser pointer and a UV LED.
Olight do have non-pro versions of this torch, but you’ll need to choose between either the green laser or UV LED together with the white light. The Pro gives you all three and a bigger 1500mAh battery, but is a tiny bit thicker and heavier than the dual mode torches.
The torch feels well made, built almost entirely from aluminium. But it only comes with an IPX7 rating so it’s not as waterproof as most other torches in Olight’s range with an IPX8 rating. It’s drop proof to 1 metre according to Olght.
It’s very slim at just 16mm (0.63″) thick, which is around the same thickness as my RovyVon A8 keychain torch that I carry with me everywhere. It’s 120mm (4.72″) long and 27mm (1.06) wide and weighs 111g (3.92oz) but with its slim design and comfortable pocket clip I would still consider this an EDC torch.
It fits nicely even in a jeans pocket and despite its weight I barely notice it. It’s a two way pocket clip, but you’ll most likely use it bezel down, mostly hidden, with the base of the torch almost flush with your pocket entrance – commonly known as deep carry.
I have the black version but Olight also offers it in Orange and Zombie Green.
In the box you get the torch itself, a magnetic charging cable and an instruction manual.
This magnetic charging cable, used with most Olight torches is proprietary, but it does make the torch very easy to charge. The torch has a magnetic base which snaps positively to the magnetic charging cable.
The magnetic base also makes it a convenient work light if there’s anything metal around to attach it to. A full charge takes around 2.5 hours which is on the slow side. The charging LED changes from red to green when it’s fully charged. As much as I like the magnetic charging cable I do wish Olight could introduce an additional USB-C charging port. You’re completely stuck if you forget the cable or it fails.
Despite its multiple modes, like most Olight torches it’s easy to use. The selector dial switches between the UV LED, the laser pointer and the white light. This dial lines up with the emitters which is a nice touch.
The white light user interface is almost identical to every other Olight torch. A single press turns the torch on and off. A double press with the torch on or off activates the 1300 turbo mode. The turbo mode runs for 4 minutes before dropping to 416 lumens for 126 minutes. I’ll test this shortly. A triple press with the torch on or off activates the strobe mode.
With the torch on, holding down the power button cycles between the 15 lumens 55 hour low mode, 100 lumens 9 hours 45 minute medium mode and 420 lumens 135 minute high mode that then drops to 100 lumens for a further 12 minutes. The four level battery level indicators light up briefly when you turn the torch on.
A 2 second press of the power button with the torch off will lock the torch. A 1 second press will unlock the torch if it’s locked and enter the 1 lumen moonlight mode whether it’s locked or not. The lock and moonlight mode is a little confusing since it only works with the dial in white light mode, and if you hold the button too long you lock the torch rather than entering the intended moonlight mode. In moonlight or turbo mode, holding down the power button then cycles between the low, medium and high modes.
There’s also the usual Olight timer modes. Choose your brightness mode and double press and hold the power button to activate the timer. The torch blinks once for the 3 minute timer and twice for the 9 minute timer. This is a great feature for camping or if you’re using the torch as a bedside light.
In laser mode a single press turns the laser on and off. A double press with the torch on or off turns on the white light with the laser in high mode. You can then cycle the brightness between low, medium and high holding down the power button. Being able to use both the laser and white light together is a great feature. Turbo mode isn’t available with the laser though.
Olight has two variants of this torch, one with a Class 1 0.39mW laser that I have, and a more powerful 5mW Class 3R laser that is only available in certain countries like the US. I found the Class 1 laser powerful enough for its intended use in an educational environment and personally wouldn’t want a more powerful laser with children around.
The UV mode has no hidden features – a single press turns it on and off. It’ll run for 5 minutes at its maximum 900mW output before dropping to 560mW for 310 minutes.
Performance
As usual Olight don’t specify the exact LED used, but most likely the white LED is an OSRAM P9 and in the UK at least there’s only a cool white version available. I measured the colour temperature in turbo mode with my colour spectrometer. It came in at 6240K with a very slight green tint which I measured at 0.0017 Duv.
I measured the colour accuracy at 72, very slightly better than its spec’d 70 but I’d really like Olight to offer some higher CRI torches.
Next I measured runtime in turbo mode with a fully charged battery in my calibrated DIY lumen chamber. I measured an impressive 1459 lumens at turn on which dropped to 1444 lumens at 30 seconds and only dropped to its spec’d 1300 lumens after around 3 minutes. At around 4 minutes it’d dropped to 450 lumens which is held for around an hour so way off its spec’d 126 minutes, but still quite acceptable. The torch remains remarkably cool in turbo mode – I measured just over 40°C. Using it in the real world with a cool breeze you should get slightly longer runtimes.
The white LED has a 2608cd or 102m (335ft) range and feels about right for an EDC torch but a little floody for my tastes. You can see above how its beam compares to Olight’s Baton 3, Seeker 4 Mini and Warrior Mini.
I don’t have a lot of use for the UV light, but it appears to work just fine and it is useful for checking bank notes.
The laser pointer is more useful, to me at least, and it’s bright enough to work in broad daylight – even with its comparatively low power compared to the version available in the US. I’d say its range is around 30m (100ft) depending on ambient light.
Conclusions
The Arkfield Pro is not going to be for everyone, but I liked it more than I thought I would. I didn’t have it for my pocket torch round-up, but I reckon it would have done pretty well. If you’re doing a lot of presentations the laser is genuinely useful and I do like having the option to use it together with the white LED. I have less use for the UV light but it’s still nice to have.
I’ve not tested a flat torch like this but I can see why a lot of people like them. It is very comfortable in your pocket and it does make a great EDC torch. The 1300 lumen turbo mode is plenty for a torch like this and you get a decent amount of time before it drops to its high mode which is very well regulated. My only real complaint is the lower than spec’d runtime in high mode, and the current lack of a neutral white version, in the UK at least.
If you don’t need the extra LEDs and prefer a more traditional torch, the Baton 3 Pro is comparable to the Arkfield Pro and still one of my favourite torches in Olight’s range. It’s brighter with more throw and it’s a bit cheaper too. But it is noticeably fatter in your pocket. If you like the idea of a slim flat torch, the non-Pro Arkfields are still available and at a lower price. You just need to choose whether you prefer a laser or a UV light.
