10 Best Streamlight Flashlights 2025 in the United States

The Streamlight 66134 Stylus Pro USB is a compact and durable penlight, made from aircraft-grade aluminum, making it tough enough for everyday use in activities like hiking, cycling, or medical tasks. It offers a bright 350 lumens output, which is quite powerful for its small size, and can illuminate up to 109 meters, suitable for seeing clearly at a distance. The rechargeable lithium-ion battery is a handy feature, allowing you to recharge via USB without needing to constantly replace batteries, although the runtime is relatively short—about 1.5 hours on high mode, so it may need frequent charging during extended use.

Its lightweight design (just 1.76 ounces) and included nylon holster make it easy to carry around or clip on your belt. The sliding metal sleeve protects the USB port from dust and damage, enhancing the durability. It’s water-resistant (rated IPX4), so it can handle some rain or splashes but isn’t fully waterproof.

This flashlight is an excellent choice if you want a reliable, portable light source with good brightness and easy USB recharging, especially if you value durability and compactness over very long battery life.

The Streamlight 69456 TLR-7 X USB is a compact tactical weapon light designed for secure and versatile weapon mounting. With a brightness of 500 lumens and a beam distance of 140 meters, it provides strong illumination suitable for tactical situations. The light's runtime varies between 1 to 1.5 hours depending on the battery type you choose, allowing for some flexibility depending on your usage. The multi-fuel technology is a significant advantage, allowing you to use either the included USB rechargeable Lithium-Ion battery or standard CR123A batteries, which can be very convenient in different circumstances.

The rail clamp system ensures that the light can be quickly and safely attached or detached without the need for tools, which is a practical feature for rapid deployment. It’s also very lightweight, only 2.72 ounces, making it easy to handle without adding significant weight to your weapon. The light is made from durable aluminum and glass and is waterproof up to 1 meter for 30 minutes (IPX7 rating), giving it good durability in various conditions.

However, the runtime might be a bit limited for extended operations, and you might need to carry extra batteries. Additionally, while it fits a broad range of weapons using the key kit, you’ll need to ensure compatibility with your specific firearm as per Streamlight's fit guide. It’s an excellent choice for tactical, hunting, law enforcement, and everyday carry purposes, given its blend of power, durability, and versatility.

The Streamlight 66604 MicroStream is a compact and powerful flashlight, ideal for everyday carry and a variety of activities such as hiking, camping, and professional use. With its 250-lumen output on high and 50 lumens on low, it offers good brightness and versatility. The beam distance is 68 meters on high and 31 meters on low, which is quite impressive for such a small device. It runs on a rechargeable Lithium-Ion battery, providing 1.5 hours of runtime on high and 3.5 hours on low, and includes a USB cable for easy recharging.

The flashlight's durability is enhanced by its metal construction and impact resistance, making it reliable for tough conditions. The IPX4 water resistance rating ensures it can withstand splashes of water, but it may not hold up to full submersion. Weighing just 2.08 ounces and measuring 3.87 inches in length, it is lightweight and easy to carry, with a removable pocket clip and lanyard for added convenience.

However, the limited runtime on high may be a drawback for some users, and the 68-meter beam distance, while decent, might not be sufficient for those needing long-range illumination. The flashlight's compact size and the built-in charging port protection are notable advantages, and it comes with a limited lifetime warranty. The Streamlight 66604 MicroStream is a solid choice for those in need of a reliable, portable flashlight.
