We read Olight's description of the Arkfeld Pro on 9 October 2026. Olight's own page did not show its full specification table to us, so the mode and runtime figures below come from retailer listings that reproduce Olight's data sheet. We say which is which. We have not handled this light.

Research-based score out of 10. The overall score is the average of the four parts below.
- White light, 365 nm UV and green laser in one flat body
- Glass lens
- 1,500 mAh battery, 43% larger than the earlier Arkfeld
- Five-level battery indicator
- Top brightness lasts minutes
- Built-in battery cannot be swapped
- Charges through a magnetic cable, not plain USB-C
- Laser is marketed as a pet toy
The short answer
Consider it if
- You want one pocket tool for a torch, a UV inspection light and a pointer.
- You like a flat light that sits in a shirt or jeans pocket.
- You are fine charging it with its own cable.
Skip it if
- You need sustained high output for search or cycling.
- You want replaceable batteries for long trips.
- Children will have access to it.
How long do 1,300 lumens last?
Olight leads with 1,300 lumens. Retailer spec sheets for this model list that turbo output as lasting about 4 minutes before the light steps down to protect itself from heat, with the 420-lumen level running for around 126 minutes.
| Level | Output | What it is for |
|---|---|---|
| Turbo | 1,300 lm, about 4 minutes | A quick look across a yard |
| High | 420 lm, about 2 hours | The realistic maximum |
| Medium | 100 lm | Walking, working |
| Low | 15 lm | Indoors at night |
| Moonlight | 1 lm | Reading a map, not waking anyone |
This is normal for a light this small, and 420 lumens is plenty for everyday use. Just know that the number on the box describes a burst. The beam reaches about 102 metres with 2,608 candela, which makes it a wide flood light, not a spotlight.
"Up to 11 days" versus 55 hours
Olight's description promises a "max runtime of 11 days". Retailer spec sheets list runtimes from 2.1 to 55 hours. Eleven days is 264 hours, so the two figures do not match.
The larger number will be the 1-lumen moonlight mode at best. Whichever is right, neither describes how you will use it. Plan on about two hours at the 420-lumen level and you will not be caught out. The battery is sealed in, so when it runs down on a trip you need its magnetic charging cable and a power bank.
Treat the laser as a laser
The green laser is Class 3R, the class just above ordinary presentation pointers, at about 5 mW. Olight's description suggests it as a "pets toy". We disagree. A Class 3R beam can injure an eye on direct exposure, and a cat chasing a dot will look straight at the source sooner or later. Use it for pointing at things and never at people, animals, vehicles or aircraft.
The UV light is 365 nm at up to 900 mW, strong enough to make stains and security marks fluoresce. Do not look into it or shine it on skin for long.

FAQ
How bright is the Olight Arkfeld Pro?
Up to 1,300 lumens in turbo, which lasts about four minutes. The level you can hold for a couple of hours is 420 lumens.
Can you replace the battery?
No. The 1,500 mAh battery is built in and charges through Olight's magnetic cable.
Is the laser safe for playing with cats?
We would not use it that way. It is a Class 3R laser, which can injure eyes on direct exposure.
Did you test it?
No. This review uses Olight's description and retailer spec sheets, and says which figures come from where.
Verdict
The Arkfeld Pro packs three useful lights into something the size of a pack of gum, and $90 is fair for that. Read the 1,300 lumens as a burst and the 11 days as a moonlight figure, keep the laser away from eyes and pets, and it is an easy tool to like.
