10 Best Waterproof Flashlights 2025 in the United States

The OLIGHT Arkfeld Pro is a versatile and compact flashlight designed for outdoor use, emergencies, and everyday carry. It offers a strong 1300-lumen white light, combined with specialized green and UV beams, making it useful for various situations like inspection, hunting, or detecting substances invisible to normal light. Its rechargeable lithium polymer battery and included charging cable add convenience, along with a battery level indicator that helps you monitor power.

Constructed from durable aluminum, the flashlight provides a solid feel without being too heavy, weighing just over 6 ounces and fitting easily in a pocket. It features waterproof capabilities, allowing it to handle wet conditions. The high UV output at 365nm is a notable advantage, delivering a more professional-grade UV light compared to many competitors.

This flashlight is ideal for users seeking a multi-purpose, durable, and high-brightness waterproof light that is easy to carry, especially outdoor enthusiasts or professionals who require white, green, and UV light options all in one device.

The OLIGHT I3T 2 EOS is a compact and lightweight flashlight designed for everyday carry and outdoor activities like camping and hiking. It offers a solid brightness of 200 lumens with a beam distance of up to 62 meters, which is good for close to medium range visibility. One neat feature is its dual-output tail switch, letting you start on low or high brightness depending on your need. It runs on a standard AAA alkaline battery, which is easy to find and replace, but you can also use rechargeable batteries to push the brightness up to 300 lumens if desired. The IPX8 waterproof rating means this flashlight can handle being submerged up to 3 meters underwater, making it reliable for wet or rainy conditions.

It’s made from durable aluminum and weighs just 1.76 ounces, so it’s sturdy without being bulky. A handy dual-way pocket clip allows you to attach it securely to belts or pockets in different positions, which adds to its convenience. The runtime on high brightness is relatively short at around 19 minutes, which could be limiting if you need longer use without changing batteries. While 200 lumens is bright enough for general use, it may fall short if you require very powerful illumination for more intense outdoor tasks. The OLIGHT I3T 2 EOS is well suited for users looking for a small, waterproof flashlight that’s easy to carry and performs well in everyday and outdoor settings, especially when portability and waterproofing are key priorities.

The OLIGHT Seeker 4 Pro Rechargeable Flashlight stands out with its impressive brightness, boasting 4600 lumens, making it suitable for emergencies, camping, and searching. It has a solid waterproof rating of IPX8, ensuring reliable performance even in wet conditions. The beam distance is notable at 260 meters, which makes it handy for long-range visibility.

Durability is ensured by its aluminum construction, although it might be slightly heavy at 1.3 pounds, which could be a drawback for some users seeking a lighter flashlight for portability. The flashlight operates on a rechargeable lithium-ion battery, which is included, adding convenience and long-term cost savings. The dual charging options (USB-C and magnetic) enhance its usability, and the enlarged switch is practical for use with gloves.

The size (1.1 x 1.1 x 5.2 inches) is compact but might be slightly bulky for everyday carry. The multi-functional holster is a nice addition, providing storage and charging convenience. The OLIGHT Seeker 4 Pro is a robust, high-powered flashlight ideal for users needing strong illumination and durability, though its weight might be a minor concern for some.
