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 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.

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.
