10 Best 18650 Flashlights 2026 in the United States

The OLIGHT Odin Mini is a compact tactical flashlight designed for outdoor and hunting use, offering a strong brightness of up to 1,250 lumens and a beam that reaches 240 meters, which is great for spotting targets at a distance. It uses a custom rechargeable lithium-ion polymer battery, providing about 5 hours of runtime. Its size is fairly compact and weighs around 6.2 ounces, making it portable but a bit heavier than some smaller flashlights.

Durability is solid thanks to stainless steel construction and a waterproof design, so it can handle tough environments. The flashlight comes with a versatile Mlok rail mount compatible with other mounting systems, plus a remote pressure switch, making it easy to control when attached to weapons or gear. Charging is convenient with a magnetic USB cable that supports fast charging, reducing downtime for recharging.

It also features multiple light modes for different lighting needs. While the battery life may not last all night for extended use, and its weight might be noticeable if carried for long periods off a weapon, the OLIGHT Odin Mini is an excellent choice if you want a bright, sturdy tactical flashlight with flexible mounting and quick recharge options, especially suited for hunting or security tasks.

The OLIGHT Arkfeld Ultra is a compact, pocket-friendly flashlight that combines three types of light in one device: a very bright white light (1400 lumens), a UV light, and a green beam. This makes it versatile for many situations like camping, emergency use, or checking things that need UV light. The brightness is strong for an everyday carry, and the focused beam angle (about 10 degrees) means it can reach a good distance.

It’s made from tough aluminum with a scratch-resistant glass lens, so it’s built to last and handle rough use. At just over 4.7 inches and weighing about a quarter pound, it’s small and light enough to carry comfortably all day. It runs on a rechargeable lithium polymer battery and can last over 5 hours, which is decent for this brightness level. The flashlight offers multiple modes to switch between white, UV, and green lights, adding to its functionality.

One downside is that the runtime under the brightest setting is relatively limited compared to some larger flashlights, and the narrow beam angle might not be ideal if you want wide flood lighting. Charging is convenient since the battery is included and rechargeable. This flashlight is well suited for users who want a durable, multi-purpose light they can carry daily, especially if they value the unique UV and green light features alongside strong white illumination.

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.
