Olight is putting serious tech into pocket lights with the new ArkPro series, a flat-bodied trio that blends utility lighting with pro-minded features. The ArkPro Lite, ArkPro, and ArkPro Ultra share a sleek aluminum form factor but diverge in capability, price, and materials to hit different everyday carry and worksite needs.
A three-model lineup with 4‑in‑1 lighting
The ArkPro Lite covers the essentials with a white emitter, a red LED for night vision preservation, and a 365nm UV LED for inspection tasks. Stepping up, the ArkPro and ArkPro Ultra add a true 4‑in‑1 system: a wide, uniform floodlight; a tighter spotlight for reach; a 365nm UV; and a built‑in green laser.

In demonstrations, the flood beam was notably smooth and free of distracting hotspots, while the spot mode pushed out to an estimated 200 meters—solid performance in the compact class when measured by the ANSI/PLATO FL 1 beam‑distance method. The UV wavelength is tuned for practical inspection work, helping reveal stains, resin cure trace, or counterfeit detection better than the more common 395nm LEDs found in budget lights.
The laser is rated at ≤5mW, falling into Class 3R territory under IEC and FDA guidelines. Notably, it can run concurrently with flood, spot, or UV—useful for pointing out hazards while simultaneously lighting the area.
ArkPro Ultra: new LED, higher output, tougher shell
The flagship ArkPro Ultra debuts Olight’s self‑developed EIP 1 LED, engineered for a neutral, consistent tint across brightness levels. Olight cites a Duv below 0.006, which indicates minimal green shift from the blackbody locus in the CIE 1931 color space—welcome news to users who care about clean, natural‑looking light.
Efficiency is a headline spec: 134 lm/W is unusually high for a compact multipurpose light, where 90–110 lm/W is more typical once optics and thermal constraints enter the equation. The Ultra also bumps max output to 1,700 lumens, compared with 1,500 lumens on the standard ArkPro.
Durability gets a lift via an OAL enhanced aluminum alloy designed to better resist impacts and abrasion. The Ultra also introduces ArkBeat, a subtle 15‑second pulse effect that evolves in color with cumulative use—a quirky but clever way to visualize how much you rely on your light.
Despite the upgrades, the form stays pocket‑friendly. The Ultra comes in at around 115g, while the standard ArkPro is roughly 120g, keeping the flat profile viable for front‑pocket carry or clip‑in bag compartments.
Controls, safety, and build details
All ArkPro models use a recessed rotary dial to switch modes—a practical choice when operating with gloves or in wet conditions. A separate side switch independently toggles the green laser, preventing accidental mode changes when you only need a pointer.
With an IPX7 rating, the lights are designed to survive immersion in up to 1 meter of water for 30 minutes, a standard benchmark for serious EDC gear. That level of sealing, combined with an aluminum chassis and protected controls, positions the ArkPro family for field techs, first responders, and DIYers who abuse their tools.
On the safety front, Class 3R lasers are limited to ≤5mW and should never be directed near eyes. The benefit is visibility—green wavelengths are perceived more brightly by the human eye, making the pointer more effective in daylight alignment or long‑distance signaling than red equivalents, according to laser safety literature from IEC 60825‑1 and FDA CDRH guidance.
Use cases and competitive context
The ArkPro series straddles worklight and EDC roles. Flood mode covers close‑quarters tasks like wiring or engine bays; the spot mode handles outdoor navigation; UV supports inspection; and the laser aids instruction and alignment. It’s a rare all‑in‑one approach—most compact rivals from brands like Fenix and Nitecore focus on raw lumens or throw, but seldom integrate 365nm UV and a pointer without bulky attachments.
From a color‑quality standpoint, keeping Duv tightly controlled matters for accurate material assessment. While Olight doesn’t quote CRI, the claimed tint stability across output steps suggests careful LED and driver tuning—an area where many high‑output pocket lights still compromise.
Pricing and availability
The ArkPro Lite is listed at $79.99, the standard ArkPro at $99.99 (with special color editions at $109.99), and the ArkPro Ultra at $129.99. A worldwide rollout is planned, positioning the lineup as a premium but attainable option for users who want more than a single‑mode torch in their pocket.
Bottom line: Olight’s ArkPro family pushes beyond “just bright” by combining nuanced beam control, safety‑minded laser integration, and a tint‑focused flagship LED. For users who juggle inspection, navigation, and task lighting, this is a thoughtfully engineered, one‑tool solution.
