Performance & carry

The stainless steel two-way pocket clip allows for convenient deep pocket carry and quick access. The slim rectangular shape of the EDC (Everyday Carry) makes it comfortable to carry, as it lays flat and feels less bulky than a cylindrical flashlight of similar size.

Additionally, the shape provides a stable and comfortable grip, eliminating the need for knurling or other grip textures. The on/off switch button is easily accessible, consistently located in the expected position, so there is no need to rotate the flashlight in search of the switch.


The Arkfeld UV Flashlight boasts an aluminum body that is not only lightweight, but also rugged and durable. It can withstand rigorous use without compromising the flashlight’s performance. Additionally, the flashlight features a resilient anodized finish that proudly displays any scuffs and scrapes. With an IPX7 waterproof rating, the Arkfeld can even be submerged in water up to 1 meter for 30 minutes.

Light modes

The Arkfeld flashlight offers five light modes, including a strobe function, providing a wide range of lighting options. These models include:

Moon mode: One lumen

Low mode: Fifteen lumens

Medium mode: Sixty lumens

High mode: Three-hundred lumens

Turbo mode: One-thousand lumens

Strobe mode: One-thousand lumens

To extend battery life, the output of High and Turbo modes is automatically reduced after a certain period of time. Turbo mode decreases from 1,000 to 300 lumens after 4 minutes, while High mode decreases from 300 to 60 lumens after 140 minutes.

Switching between modes is simple. Press and hold the button to turn on the flashlight in Moon mode. Press and hold again to switch to Low, Medium, and High modes. Double-click to activate Turbo mode and triple-click to engage Strobe mode.

The Arkfeld flashlight features a white LED that produces a well-balanced, uniform beam with a distance of up to 85 meters. Additionally, a thumb button located near the front of the flashlight controls the on/off function and toggles between the white LED and UV modes for added versatility.

Power button and modes
