10 Best Pen Flashlights 2026 in the United States

The OLIGHT Oclip Pro EDC Flashlight is a compact and versatile pen-flashlight that shines with a maximum brightness of 500 lumens. This level of brightness makes it suitable for a variety of uses, from cycling to outdoor adventures and indoor tasks. The flashlight features three lighting options: a powerful floodlight, a spotlight with a 120-meter range, and a low-intensity red light, catering to different lighting needs. The user-friendly design allows for easy switching between modes, and the battery indicator keeps you informed about its charge level.

One of the Oclip Pro's highlights is its lightweight build, weighing only 1.87 oz (53 g) and measuring just 2.24 inches (57 mm) long. This portability makes it an excellent choice for everyday carry. Additionally, the flashlight is designed with multiple fixing methods, including a magnetic base and a lanyard hole, allowing for convenient attachment and use in various situations. The Type-C rechargeable feature adds to its practicality, and being IPX6 waterproof ensures it can withstand splashes and rain.

There are a few drawbacks to consider. While the flashlight is highly portable, its small size may compromise the functionality of larger flashlights, particularly in terms of battery life under heavy use. The initial moonlight mode can be a bit confusing for first-time users, requiring a long press to switch modes. Furthermore, while the durability is good for everyday use, those seeking a rugged flashlight for extreme conditions might want to explore options with tougher construction.

The OLIGHT O'Pen 3 is a versatile pen-flashlight combining practical lighting and writing tools in one compact design. It offers a bright white LED light with 120 lumens, suitable for everyday tasks like office work, presentations, or quick outdoor use. One unique feature is its four light modes, including a safe green beam for presentations, a red light to preserve night vision, and a soft pen-tip light for close-up writing. This multifunctionality makes it a handy tool for professionals who need both illumination and a quality pen.

It uses a rechargeable lithium-ion battery charged via a convenient USB-C port, which fully charges in about an hour and provides up to 25 hours of runtime. This reduces the need for frequent battery replacements, making it great for regular carry. The pen itself is built from durable 6061-T6 aluminum alloy, keeping it lightweight at just 33.5 grams, and it features a secure spring-loaded clip for easy pocket attachment.

The switching mechanism is a smooth, bolt-action toggle that allows quick one-handed changes between light modes, ideal for meetings or fieldwork. The pen’s grip is textured for comfort during extended writing, and it includes extra refills, emphasizing its dual purpose as a professional writing instrument. While the maximum beam distance is not emphasized, the lumen output and pen size suggest it is best suited for close to medium range lighting rather than long-distance use. Additionally, the integrated rechargeable battery means it cannot be swapped out quickly in the field.

The OLIGHT O'Pen 3 pen-flashlight presents a practical, multifunctional everyday carry tool that balances good brightness, durability, and premium writing performance, making it suitable for office workers, technicians, and outdoor enthusiasts seeking a compact light and pen combination.

The OLIGHT Arkfeld Pro is a compact and versatile pen-flashlight designed for everyday carry and outdoor use. It packs a strong 1300-lumen white LED, delivering bright and clear illumination suitable for most tasks. What sets it apart is the inclusion of three light sources: white, green beam, and a powerful UV light at 365nm, which is stronger and more professional than typical UV flashlights. This makes it useful not just for general lighting but also for specialized needs like detecting fluorescent materials or working in dark environments.

The flashlight is rechargeable with a built-in lithium polymer battery, and it features a helpful battery level indicator that shows you how much power remains, so you’re not caught off guard. Its sturdy aluminum build offers good durability and water resistance, making it reliable in various conditions. The size is compact, fitting comfortably in your pocket at just under 5 inches long and weighing about 6 ounces, so it’s easy to carry around all day.

Switching between the three light modes is done via a circular selector, which is intuitive but might take a little getting used to if you prefer simpler on/off buttons. The green beam output is low-powered (class 3R), which is safe but less bright compared to the white light, mainly serving specialized purposes rather than wide illumination. For those seeking a pocket-friendly flashlight that covers general bright lighting and also offers UV and green light options for outdoor, emergency, or work use, the Arkfeld Pro represents a solid choice. However, if you only need a basic white light or prefer simpler controls, this might feel a bit more complex than necessary.
