10 Best Pen Flashlights 2025 in the United States

The OLIGHT Arkfeld Ultra is a compact and versatile pen-flashlight designed for everyday carry and outdoor use. It delivers a strong 1400 lumens of white light, which is bright enough for most tasks like working, camping, or emergency needs. In addition to the white beam, it offers a UV light and a green beam, expanding its usefulness for checking items, detecting stains, or special signaling.

The flashlight uses a rechargeable lithium polymer battery, which is convenient and eco-friendly, and it includes a magnetic charging cable for easy recharging. Its size is slim and lightweight (just over 4 ounces), making it comfortable to carry in a pocket without feeling bulky. Made from O-aluminum, the Arkfeld Ultra feels sturdy and durable, with a high-quality glass lens that resists scratches and maintains clear light output over time. The matte olive-green finish gives it a sleek, modern look, and it is also waterproof, which helps in various weather conditions.

While it has multiple beams, the green and UV lights are relatively low power (green ≤5mW), so they are best suited for specific tasks rather than illumination. Also, the compact size means its battery life might be shorter under high brightness use compared to bigger flashlights. This pen-flashlight is ideal for those looking for a reliable, multi-purpose light that can handle daily tasks, outdoor adventures, and specialized needs without taking up much space.

The Streamlight 88811 Wedge is a compact pen-flashlight that's great for everyday carry and various outdoor activities. With a maximum brightness of 500 lumens and a beam distance of up to 28 meters on low mode, it delivers impressive lighting options for tasks like cycling, jogging, or camping. The design is ergonomic and lightweight at just 3.2 ounces, making it easy to carry in your pocket or attach to your gear with the included lanyard and deep carry pocket clip.

One of its standout features is the USB-C rechargeable battery, which offers convenience and sustainability. The flashlight recharges in about 3 hours and the charge indicator helps you stay updated on the battery status. The TEN-TAP programming allows users to switch between modes easily, and the five-tap lockout feature prevents accidental activation, which is a thoughtful touch for those who want to avoid draining the battery.

Durability is another strong point, with its anodized aluminum construction and IPX7 waterproof rating, meaning it can withstand being submerged in water up to 1 meter. It’s also impact resistant up to 1 meter, making it suitable for tough environments. The brightness options may be a bit confusing, as the high is rated at 500 lumens but advertised specifications mention lower lumens (300) for battery life purposes. Additionally, considering its price point, some users might find similar flashlights with comparable features at lower prices. The Streamlight 88811 Wedge is an efficient and versatile pen-flashlight well-suited for anyone needing reliable illumination during outdoor activities or everyday tasks, though potential buyers should weigh the brightness options and price against their specific needs.
