Olight ArkPro Ultra Onyx Black – 1700 Lumens – 3+1=7 – OAL Aluminum

The Olight ArkPro Ultra is a technical masterpiece that takes multifunctional lighting to a new level within a slim, pocket-friendly design. Based on the innovative 3+1=7 concept, this flashlight integrates a floodlight, a spotlight, UV light, and a Class 1 green laser pointer. Crafted from the exclusive OAL alloy, the ArkPro Ultra offers unparalleled structural integrity and a wide range of professional and recreational applications.

The ArkPro Ultra introduces groundbreaking technologies for a superior light pattern:

- EIP1 LED Technology: The floodlight incorporates the EIP1 LED developed by Olight. With an efficiency of 134 lumens per watt and an extremely low DUV value of 0.006, it produces a natural white light without color distortion.
- Output & Range: The flashlight generates up to 1,700 lumens (wide beam) and reaches a distance of 205 meters with the spot beam.
- UV & Laser: The powerful UV light (365 nm) is optimized for forensic investigation and leak detection, while the green laser pointer (<0.39 mW) serves as an accurate tool for signaling and presentation.
- Housing: Constructed from a single piece of OAL aluminum, an alloy that is nearly twice as strong as standard 6061 aluminum. The deep black Onyx finish is achieved through a specific pigment anodizing process for increased wear resistance.
- Water resistance: Certified to the IPX7 standard, providing protection against temporary submersion.

This model stands out for its personalization and operational flexibility:

- ArkBeat Color Indicator: A unique indicator on top of the housing cycles through a 254-hour color sequence. Users can lock in their favorite shade, adding a subtle touch of personalization to the interface.
- Seven Light Modes: By using the various light sources (individually or in combination), seven unique modes are created, ranging from Moonlight mode (1 lumen) for 14 days of light, to powerful search and inspection beams.
- Dual-Charging System: The integrated 2000 mAh Li-ion battery offers maximum versatility. Charging is possible via both the side USB-C port and the familiar magnetic MCC connector on the bottom.
- Ergonomic Profile: Thanks to its flat design and robust pocket clip, the flashlight fits extremely comfortably and securely in a pants pocket or on gear.

For long-term reliability of your Olight ArkPro Ultra, we recommend the following:

- Thermal Management: In Turbo mode, the flashlight reduces its output after a short period of time to prevent overheating. This is a safety feature designed to protect the internal electronics and the battery.
- Charging: Keep both the USB-C port and the magnetic charging points on the bottom free of dirt and metal filings to ensure optimal power transfer.
- Lens Maintenance: The optical lenses can be easily cleaned with a soft microfiber cloth. Do not use harsh chemicals to preserve the coatings on the TIR lenses.
- Laser Safety: Although this is a Class 1 laser, direct contact with the eyes must be avoided at all times.

The Olight ArkPro Ultra Onyx Black is a technically robust all-in-one solution for the modern user. The combination of the extremely durable OAL housing, the color-accurate EIP1 LED, and the versatile 3+1=7 functionality makes this a superior tool in the EDC market. The objective assessment is that the ArkPro Ultra, with its dual charging options and innovative ArkBeat indicator, offers an unmatched blend of power, durability, and ease of use.
