Olight is packing some heavy tech into their pocket lights with their new ArkPro series—a flat, pocketable trio of lights that mix utilitarian EDC lighting with pro-grade features. The slim aluminum body is size matched across the ArkPro Lite, ArkPro, and ArkPro Ultra but split by power, price, and material to hit a variety of every day carry (EDC) and work site requirements.
Three models with 4‑in‑1 lighting
It’s covering the basics with a white emitter, red LED for preserving your night vision, and 365nm UV LED for those inspection tasks.
Leading the charge, the ArkPro and ArkPro Ultra introduce the industry’s first true 4‑in‑1 system: a broad, even floodlight; a focused spotlight for distance; a 365nm UV; and a dedicated green laser that embed in one device.
On demo, the flood beam was smooth and uniform, lacking bothersome hotspots, and the spot mode reached out to an estimated 200 meters, good performance for a compact using the ANSI/PLATO FL 1 beam‑distance technique. The UV wavelength is optimized for excellent inspection results even in a low-dimishing state, making stains, resin cure trace, and couterfied detection noticeable – better than popular 395nm LED lights in budget range.
The laser outputs ≤5mW, and it falls into Class 3R according to IEC and FDA standards. Tellingly, it can be used in parallel with flood, spot, or even UV— great for highlighting hazards while illuminating at the same time.
ArkPro Ultra: fresh LED, more output, harder shell
The flagship ArkPro Ultra introduces Olight’s self‑developed EIP 1 LED, which guarantees a neutral and stable tint, even at varying brightness levels. Olight refers to a Duv of below 0.006, suggesting very little green shift in the blackbody locus in the CIE 1931 colour space—good news for directioners who prefer clean, neutral‑looking light.
Now I come to efficiency – that’s a headline spec: 134 lm/W is really high for a compact trade-off light – 90-100lm/W is about what you’ll see when you take into account optics and thermal constraints. The Ultra also increases max output to 1,700 lumens from the standard ArkPro’s 1,500 lumens.
Durability receives a boost with the use of OAL (optimum alloy light/impact resistant) aluminum, which is intended to be better protected against impacts and scrapes. The Ultra also features ArkBeat, a dim 15‑second pulse effect that grows in intensity with use over time as a “way to see how much you’re using your light.”
Pocket‑friendly, too — despite the upgrades. The Ultra is about 115g, and the standard ArkPro is about 120g, so the flat profile still works for front‑pocket carry, or clip‑in bag sections.
Controls, safety and build details
ArkPro models universally switch modes with a recessed rotary dial, a logical design for changing modes with gloves or in rainy environments. A dedicated side switch conveniently changes lighting modes and the green laser by a separate button to maintain your settings when you only need a pointer.
The lights are built to survive immersion in up to 1 meter of water for 30 minutes—they have an IPX7 rating, a standard benchmark for the kind of serious EDC gear that can handle itself in less-than-ideal conditions. That degree of sealing, along with an aluminum chassis and protected controls, places the ArkPro family in the hands of field techs, first responders, and DIYers that can’t leave their stuff alone.”
From a safety perspective, Class 3R lasers are capped at ≤5mW and should not be directed at or allow to re flect into the eyes. The advantage is that green wavelengths are seen more easily by the eye of a human observer, which makes the pointer more effective than red ones for use during day‑light alignment, and are less likely to cause time‑averaged retinal damage according to laser safety literature as IEC 60825‑1 laser safety Standard and FDA CDRH guidance.
Applications and competitive context
The ArkPro range bridges the gap between worklight and everyday carry. flood mode for close‑quarters tasks such as wiring or engine bays; spot mode for outdoor navigation; UV for inspection; and laser for instruction and alignment. That’s a much more all‑in‑one approach; the main competition cropping up from the likes of Fenix and Nitecore are mostly dedicated to raw lumens or throw, not to mention they generally don’t include 365nm UV or a pointer without a full and bulky attachment.
From a color‑quality point of view, it is important to keep D u v tightly controlled to ensure the accuracy of material assessment. I’d like to see CRI stated, which Olight doesn’t quote, but the claimed steadiness of the tint across output levels indicates some quite careful LED and driver tuning, an area into which many pocket lights with high maximum outputs still don’t put that much effort.
Pricing and availability
The ArkPro Lite costs $79.99, the regular ArkPro $99.99 (color editions: $109.99) and the ArkPro Ultra $129.99. And there are plans for a global rollout, which will place the lineup as a premium, but attainable, next-best thing for users who want more than a single‑mode torch in their pocket.
Bottom line: The ArkPro family from Olight steps beyond “just bright” with nuanced beam control, safety-focused laser integration, and a flagship tint-focused LED.
For Multi-taskers – who change inspection, navigation, and task lighting, this is an engineered one‑tool solution.
