10 Best Pen Flashlights 2025 in the United States

The OLIGHT IMINI 2 EDC Rechargeable Keychain Flashlight is a compact and lightweight flashlight that fits well in the pen-flashlight category, making it a great choice for everyday carry or emergency situations. With a brightness of 50 lumens, it offers adequate illumination for close-range tasks, although it may not light up larger areas due to its limited beam distance of 1.5 meters. The built-in rechargeable battery is a significant plus, allowing for convenient charging through a USB plug, which takes just 60 minutes for a full charge.

One of the standout features is its instant activation; you can turn it on simply by detaching it from the magnetic cap, which is user-friendly. The flashlight also has a magnetic base, enabling a hands-free experience when attached to metal surfaces—ideal for tasks that require both hands.

While the 50-lumen output is sufficient for many everyday uses, it may not be bright enough for tasks that require more powerful lighting. Additionally, the flashlight is designed primarily for close-range visibility, which might limit its effectiveness in certain outdoor scenarios. The small size and lightweight design (only 19.5 grams) are perfect for carrying around, but users should be cautious with its durability despite being made of aluminum and rated for a 1.5-meter drop resistance.

The GearLight S100 LED Pocket Pen Light is designed for those who need a reliable and compact flashlight for close-up tasks. Its standout feature is its compact size, measuring just 5.25 inches in length and weighing 1 ounce, which makes it ideal for carrying in a pocket or clipping onto a belt or bag. This portability is enhanced by the included removable clip, making it a convenient choice for professionals like nurses and mechanics, as well as for everyday use in inspections or repairs.

The flashlight offers a brightness level of 100 lumens, which is suitable for lighting up concentrated areas. Powered by two AAA batteries, it provides adequate illumination for various tasks, although the batteries are not included with the purchase. The light source is LED, known for its energy efficiency and longevity, further adding to the product's appeal.

In terms of durability, the GearLight S100 is made from military-grade aluminum, making it tough enough to withstand drops and temporary water exposure. This durability makes it a reliable choice for rough handling situations, such as outdoor activities or emergencies. The flashlight's design also features an easy-to-use switch, enhancing its practicality in urgent scenarios. Potential buyers should consider the need for frequent battery replacements, given the reliance on AAA batteries, which may be a downside for some. This pen-flashlight is best suited for those prioritizing portability and durability over high lumens or extensive beam distance.

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.
