Surefire X300 vs Streamlight TLR-1: Which one is better?

When it comes to high-quality tactical flashlights, Surefire and Streamlight are two of the top brands that come to mind. In this article, we’ll take a closer look at the Surefire X300 and the Streamlight TLR-1, two popular models often compared by gun enthusiasts and professionals in the field.

The Basics

  • The Surefire X300 weighs 4.0 ounces and measures 3.6 inches. It boasts an impressive 600 lumens and uses two CR123A batteries with a runtime of 1.5 hours at the highest output.
  • The Streamlight TLR-1, on the other hand, weighs 4.18 ounces and measures 3.39 inches. It has a slightly lower output of 300 lumens and also uses two CR123A batteries with a longer runtime of up to 2.5 hours at the highest output.

Comparing the X300 and TLR-1

Both the Surefire X300 and Streamlight TLR-1 are made of high-quality materials and designed for rugged use. The X300, however, features a more durable aluminum body with a hard anodized finish that can withstand harsh conditions and impact. This makes it an ideal choice for military and law enforcement personnel who demand reliable and long-lasting equipment.

In comparison, the Streamlight TLR-1 is composed of a high-impact polymer body that is lightweight but may not be as durable. It is still a solid option for civilians who want a good flashlight for everyday use or for the occasional hunting trip.

Another important feature to compare is the beam. The Surefire X300 produces a brighter beam with longer range, making it better suited for long-distance targeting and identification. Meanwhile, the Streamlight TLR-1 produces a slightly wider and less intense beam that may work better for illuminating larger areas, such as a room or backyard.


Ultimately, both the Surefire X300 and Streamlight TLR-1 are high-performing flashlights that offer great value for their price. The decision on which one to choose largely depends on your specific needs and usage. If you need a durable, high-output flashlight with a longer range, the Surefire X300 is the better option. If you prefer a slightly lighter flashlight with a wider beam, the Streamlight TLR-1 may suit your needs best.
