The Olight Seeker Ultra (Olive Green) is a powerful, intuitive tactical and search flashlight delivering up to 4,800 lumens of adjustable output and a beam throw of up to 265 meters. Equipped with four high-performance P9 LEDs (Cool White) and precision TIR optics, it offers exceptional illumination, while its Moon mode (5 lumens) provides up to 17 days of continuous runtime.
OAL Alloy Body: Crafted from innovative O-Aluminium (OAL) with hard anodizing, offering 1.73x greater hardness than standard 6061-T6 aluminum. Profiled silicone grip panels ensure a secure hold in wet conditions or while wearing gloves.
IPX8 Waterproof & Rugged: Fully submersible and drop-resistant up to 1.5 meters.
Rotary Switch & Smart Electronics: The smooth side rotary knob allows easy mode selection and displays battery status. Advanced temperature and power regulation stabilizes output until full battery depletion.
Multifunctional Holster: Can be mounted horizontally on a belt, vertically on a backpack, or secured to a wall/vehicle dashboard to act as a docking station. Inserting the flashlight into the holster automatically limits output to 600 lumens for safety.
