Three separate light sources are what give the Olight ArkPro Lite its versatility. The main white light reaches 1200 lumens with a balanced spot-and-spill beam for general illumination, while the dedicated 365nm UV light provides two output levels for inspecting fluorescent details, stains, residue, leaks, and documents. A separate red light offers 5-lumen and 40-lumen settings for low-light tasks where preserving natural night vision is useful, along with a 40-lumen SOS signalling mode.

The controls keep those lighting systems straightforward to manage. A rotary selector changes between white, UV, and red light, while the central button controls the selected output. White light has five brightness levels plus strobe, and the torch also includes lockout mode to help prevent unintended activation during storage.

The flat 6061 aluminium body is CNC-machined as a unibody construction and measures 111mm x 27mm x 16mm (4.37 x 1.06 x 0.63 inch). At 105g (3.70oz) including the battery, it keeps the profile slim while retaining a solid aluminium build. IPX7 water resistance, a magnetic tail, dual-way clip, USB-C charging, and the supplied magnetic charging cable complete a practical lighting setup for home, outdoor, inspection, and general utility tasks.

Key Features

• Three Light Sources In One Torch: Switch between a 1200-lumen white light, 365nm UV light, and red light without needing separate lighting tools for different tasks.
• Balanced White Beam: The white light combines spot and spill illumination with a maximum beam distance of 94m (308ft), giving useful coverage for general lighting and outdoor tasks.
• Two-Level 365nm UV Light: Select 360mW output for closer inspection or up to 1000mW for stronger fluorescent response when checking stains, residue, leaks, documents, and other UV-reactive details.
• Red Light For Low-Light Tasks: Separate 5-lumen and 40-lumen red-light modes provide softer illumination that helps preserve natural night vision, with a 40-lumen SOS mode also available.
• Flexible Charging Options: Recharge through USB-C or Olight's supplied magnetic charging cable, giving you two charging methods from the same torch.
• Slim Unibody Construction: The CNC-machined 6061 aluminium body measures 16mm (0.63 inch) thick and weighs 105g (3.70oz) including the battery, keeping the flat-profile design compact without sacrificing a solid one-piece build.
• IPX7 Water Resistance: The IPX7 rating provides protection against water exposure for use around changing outdoor conditions.
• Clear Status Indicators: Laser-microperforated indicators separate brightness and battery information using different indicator colours and matching icons.
• Lockout Function: Lockout mode helps prevent unintended activation while the torch is stored with other gear.
