10 Best 18650 Flashlights 2025 in the United States

The OLIGHT Arkfeld Pro is a versatile and compact flashlight that combines three light sources: a bright white LED with up to 1300 lumens, a strong UV light, and a green beam, making it useful for a variety of tasks such as outdoor activities, cleaning, and inspection work. Its brightness level is impressive for a flashlight of this size, providing clear illumination, while the 55-hour runtime ensures it will last through extended use. The flashlight is built from durable aluminum and meets IPX7 waterproof standards, so it can handle rough conditions and light rain without issue.

It weighs just under 6 ounces and measures about 4.7 inches long, fitting easily in a pocket for everyday carry without feeling bulky. Switching between the white, UV, and green beams is simple thanks to the circular selector, and a five-level battery indicator helps you keep track of power remaining. The rechargeable lithium-ion battery is convenient and included, eliminating the need for constant replacements.

The Arkfeld Pro is a solid choice for anyone looking for a handy, multi-functional flashlight with strong brightness, good battery life, and outdoor-ready durability.

The Streamlight 89000 ProTac 2.0 is a robust tactical flashlight that delivers an impressive 2,000 lumens of brightness, making it suitable for law enforcement, security, and inspection services. It has a solid aluminum build, ensuring durability and a lightweight feel at 8.2 ounces, making it easy to carry. The flashlight features a tactical tail cap switch for easy one-handed operation, including momentary and constant on modes, as well as a strobe function.

It is IP64-rated for dust-tight and water-resistant performance, enhancing its reliability in tough conditions. The included SL-B50 battery pack can be recharged using a USB-C cable, which is convenient and ensures you don't run out of power quickly. However, the high brightness mode drains the battery in just 2.25 hours, which might be limiting for extended use.

The TEN-TAP programmable feature adds versatility by allowing users to customize the light settings to their preferences. Although the beam distance is impressive at 262 meters, the runtime could be a drawback for prolonged operations. Given its high power, compact size, and various tactical features, the Streamlight 89000 ProTac 2.0 is a great fit for professionals in demanding fields who need a reliable and powerful light source.

The Fenix E35R EDC flashlight is a powerful option within the 18650 flashlight category, offering an impressive brightness of 3100 lumens and a beam distance of 284 yards. This makes it suitable for various outdoor activities, emergency situations, and everyday carry. Its compact size (under 4.7 inches long and weighing just 5.22 ounces) makes it easy to carry in pockets or bags, appealing to those who prioritize portability.

Ease of use is another highlight of the E35R. The simple side switch allows for straightforward operation, including a strobe feature for emergencies. A unique lockout feature prevents accidental activation, which is a thoughtful addition for those who frequently carry a flashlight.

Being USB-C rechargeable is a significant advantage, as it allows for fast charging. The flashlight can run for an impressive 69 hours on eco mode, although it lasts only an hour on the turbo setting. The battery monitoring feature is very handy, ensuring users won't be caught off guard with a dead battery.

Durability is a strong point as well. The aluminum body is designed to withstand impacts up to 1.5 meters and has an IP68 rating, making it waterproof up to 2 meters for 30 minutes. This robustness is ideal for outdoor enthusiasts or anyone needing a reliable tool in harsh conditions.

While the brightness is exceptional, the short runtime on the highest setting may not be ideal for prolonged use. Additionally, while being lightweight is a strength, some users might find it feels a bit less substantial than heavier, more rugged models. The Fenix E35R EDC flashlight is excellent for users looking for high brightness, portability, and durability, making it a reliable companion for outdoor adventures and everyday tasks.
