10 Best Pen Flashlights 2026 in the United States

The Streamlight 66134 Stylus Pro USB is a slim, lightweight pen flashlight designed for professionals like medical staff, law enforcement, and technicians who need a reliable light for close-up or low-light work. It delivers a bright 350 lumens output with a beam reaching about 109 meters, which is impressive for its compact size and ideal for inspecting small or confined spaces. Its rechargeable lithium-ion battery offers up to 1.5 hours on high brightness and charges quickly via USB in roughly 2.5 hours, removing the need for disposable batteries.

Durability is a strong point here—the aluminum body is water-resistant (IPX4) and can withstand drops from up to 1 meter, making it tough enough for everyday professional use. The light’s ultra-slim design and light weight (just 1.76 ounces) make it easy to carry in pockets or clips. The sliding metal sleeve protects the USB charging port, adding to its ruggedness.

This pen light is a solid choice if you want a dependable, bright, and rechargeable flashlight that's durable and portable for professional or everyday low-light tasks. It may not be the best fit for those needing long-lasting battery life or a very long beam, but for most inspector or medical uses, it covers the essentials well.

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.

The Streamlight 66601 MicroStream is a compact, pen-sized flashlight designed for everyday carry. It delivers a bright output of 250 lumens on high mode, lighting up to 68 meters, which is impressive for its small size. There’s also a low mode with 50 lumens for longer battery life, lasting about 3.5 hours, while the high mode runs for around 1.5 hours. It uses a rechargeable lithium-ion battery, eliminating the need for disposable batteries, and charges conveniently with a USB cable. The flashlight is made from durable aluminum, offering good resistance to wear and water, making it reliable for outdoor and emergency use.

Weighing just 1.2 ounces and measuring under 4 inches, it’s easy to carry without feeling bulky. The switch is a user-friendly push-button on the tail, which also shows charging status through red and green lights. A metal sleeve protects the charging port from dust and damage. It includes a removable pocket clip and a strong lanyard for different carry options. The runtime on high is relatively short, so frequent charging might be needed if used heavily. Also, the beam distance is decent but not exceptional compared to larger flashlights.

This flashlight is ideal for those who want a reliable, lightweight, and rechargeable pen-flashlight for everyday tasks, quick inspections, or outdoor adventures where portability and brightness matter most.
