Olight Arkfeld
The Arkfeld is Olight's flat-body EDC platform — a rectangular form factor that pockets like a phone and runs multi-source output through a single rotary selector. The lineup spans eight models, each built on the same slim chassis but scaled for different carry requirements and output tiers.
Every model in the series shares magnetic charging, a two-way pocket clip, and the flat aluminum profile that defines the platform. LED temperature varies by SKU — cool white and neutral white options are available depending on the model. What changes as you move up the line is source count, output ceiling, and build construction.
Olight Arkfeld
The Arkfeld is the foundation of the series. It pairs a cool white LED with a green laser, both controlled through the rotary selector on the head. The rectangular aluminum housing sits flat in a pocket, and the green laser provides a visible aiming point for presentations, signaling, or low-light identification. This is the baseline the rest of the lineup builds on.
Olight Arkfeld UV
The Arkfeld UV swaps the green laser for a UV emitter, turning the platform into a dual-source detection tool. The UV source runs at 365nm — the standard wavelength for currency authentication, document verification, fluid detection, and field identification of scorpions and certain minerals. If your use case leans toward inspection over laser utility, this is the purpose-built option.
Olight Arkfeld Pro
The Pro is where the platform hits its full feature set. It combines cool white output, a UV emitter, and a green laser in a single flat housing — three sources managed through one rotary selector. White light for general use, UV for authentication and detection, and a green laser for signaling or aiming, all without carrying multiple tools. Several colorways and limited editions rotate through the lineup.
Olight Arkfeld Pro Flat
The Pro Flat takes the triple-source setup and moves it into a unibody aluminum construction. Fewer seams, tighter tolerances, and a cleaner feel in hand and in pocket. LED temperature options vary by SKU — cool white and neutral white variants are both available, which is worth checking against your preference for color rendering versus raw output. If the standard Pro appeals but you want tighter build quality, this is the upgrade path.
Olight Arkfeld Ultra
The Ultra is the output ceiling of the original Arkfeld chassis. It pushes the white LED into the 1,300-lumen range while maintaining the 3-in-1 configuration — white light, UV, and green laser through the rotary selector. That is a meaningful jump over the base and Pro models without changing the flat pocket profile.
Olight ArkPro Lite
The ArkPro Lite is the entry point in Olight's next-generation ArkPro line. It carries the flat-body DNA of the Arkfeld platform into a streamlined package built for minimal pocket commitment. The Lite trims feature density in favor of lighter, more compact carry — a strong option if you want the form factor without the full multi-source stack.
Olight ArkPro Flat
The ArkPro Flat is the unibody workhorse of the ArkPro series. It runs multi-source output through a seamless aluminum body with no visible seam breaks. LED temperature is selectable at the SKU level, with cool white and neutral white variants available. The widest selection of colorways in the lineup lives here, including limited-edition finishes.
Olight ArkPro Ultra
The ArkPro Ultra sits at the top of the flat-body EDC lineup. It pushes the ArkPro platform to its highest output tier while maintaining full multi-source capability and the pocket profile that defines the series. If you want the most Olight currently puts into this form factor, this is the ceiling.
