10 Best 18650 Flashlights 2025 in the United States

The OLIGHT Baton4 Rechargeable EDC Flashlight is an impressive choice for anyone in need of a compact, reliable flashlight for everyday use, camping, or emergencies. With a brightness of 1,300 lumens and a beam distance of 170 meters, it delivers powerful illumination, making it suitable for a variety of tasks, from outdoor adventures to home repairs. Its lightweight design at just 1.85 ounces and small size (2.48 inches) makes it easy to carry in your pocket or bag, ensuring you have light whenever you need it.

One of the standout features is the solid metal switch, which adds a sense of durability and tactile feedback with every use. The flashlight also includes upgraded indicators that display battery power and brightness levels, helping you stay informed about its performance. The flat magnetic tail cap is another handy feature, allowing for hands-free lighting by attaching it to metal surfaces.

The flashlight does have some limitations. The runtime of approximately 1 hour and 13 minutes on high mode may not be sufficient for extended use, and while it's IPX8 rated for water resistance, it may not withstand extreme conditions like some rugged flashlights. Additionally, the rechargeable feature, while convenient, means you need to ensure that you have access to charging, which might be a concern in remote areas. The OLIGHT Baton4 is a well-designed flashlight that excels in brightness and portability, making it great for everyday carry. It's best suited for casual outdoor enthusiasts or those who need reliable lighting for chores around the house, but those seeking a very long-lasting battery life or extreme durability might want to consider other options.

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.

With a maximum brightness of 1600 lumens, it effectively illuminates large areas and offers an impressive beam distance of up to 181 meters. This makes it suitable for activities like dog walking, home security, and camping. The flashlight's dual-mode functionality allows for easy switching between everyday use and tactical purposes, providing flexibility based on your needs. The tail button features a memory function in EDC mode and a one-click turbo in Tactical mode, enhancing user convenience.

One of its notable advantages is its charging method. The TAC 2AA comes with a rechargeable battery, which is sustainable and can be reused. Additionally, it is compatible with any AA battery type, offering an alternative when recharging isn’t possible. Battery life is solid with a runtime of up to 177 hours, and the battery indicator helps you monitor usage. Durability is a strong suit, as the flashlight is made from sturdy aluminum and rated IP68 for water resistance, making it submersible up to 2 meters and impact resistant up to 1.5 meters. This reliability ensures it can withstand harsh weather conditions.

Though relatively lightweight and compact at 4.1 inches long and 2.6 ounces, some users might find the size slightly larger than other EDC flashlights. However, its portability is enhanced by a double-sided clip, allowing it to be easily attached to a hat or pocket. The flashlight's tail-standing function is another convenient feature for hands-free use. While the ACEBEAM TAC 2AA is highly functional and durable, its advanced features and slightly larger size might not be necessary for casual users who need a simple flashlight for occasional use. But for those who need a reliable, bright, and versatile flashlight for regular or tactical use, it’s an excellent choice.
