SureFire X300: A Comprehensive Guide for Firearm Owners
If you’re in the market for a high-quality weapon-mounted light, the SureFire X300 is one of the top choices for tactical use, whether you’re in law enforcement, the military, or an enthusiast looking for the best. Powered by two CR123A lithium batteries, the X300 delivers long-lasting, reliable performance in even the most demanding conditions. This guide will cover everything you need to know about the SureFire X300, including the differences between X300U-A and X300U-B, the X300 Turbo, how long these models last, and their compatibility with Glock firearms.
SureFire stopped making the standard X300 (with a 500-lumen output) in 2013, when they introduced the X300 Ultra models. The Ultra (X300U) line became the new standard, offering significantly brighter performance. Since then, SureFire has focused exclusively on producing the Ultra models, which provide 1,000 lumens of brightness, making the older 500-lumen X300 models obsolete.
1. What Is the Difference Between X300U-A and X300U-B?
The SureFire X300U comes in two versions—Version A and Version B—both offering the same 1,000 lumens of powerful illumination. The primary difference lies in how they attach to your firearm:
- X300U-A: Features the Rail-Lock mounting system, allowing quick attachment or detachment without tools. It works with both Universal and Picatinny rails, making it user-friendly for tactical situations where speed is crucial.
- X300U-B: Uses a T-Slot mounting system, which secures the light more tightly with a screw. While it takes longer to attach or remove compared to Version A, it offers a more secure fit, making it ideal for firearms with heavy recoil, ensuring the light stays firmly in place.
Both versions provide the same 1,000-lumen output, but X300U-A is designed for quick attachment and detachment, while X300U-B is more focused on a tighter, more secure connection.
2. What Is the X300 Turbo Edition?
The X300 Turbo (often referred to as X300T) is a high-candela version of the X300 series, designed for users who need more beam intensity and distance rather than just brightness. The Turbo edition focuses on delivering higher candela, making it ideal for long-range target identification and cutting through environmental challenges like smoke or fog.
While the X300U focuses on producing 1,000 lumens, the X300T Turbo sacrifices some lumen output in exchange for more focused, intense light, resulting in a beam that reaches further distances. Like the X300U, the Turbo version comes in both X300U-A (Rail-Lock system) and X300U-B (T-Slot system).
The X300 Turbo is ideal for users in need of high-intensity light for tactical situations requiring long-range visibility.
3. How Long Does a SureFire X300 Last?
The SureFire X300 is known for its durability and long lifespan. On a set of fresh CR123A batteries, the X300 can run for up to 1.25 hours of continuous use at full brightness. However, the overall lifespan of the light itself can extend for years with proper care and maintenance, thanks to SureFire's high-quality, military-grade materials. SureFire’s strong warranty also supports the longevity of their products.
4. SureFire X300 Glock Compatibility
The SureFire X300 is compatible with many full-size and compact Glock models, including the following:
- Glock 19
- Glock 17
- Glock 22
- Glock 23
- Glock 34
- Glock 20
- Glock 21
The X300 is designed to fit both Universal and Picatinny rails, ensuring compatibility with a wide range of firearms. Both Version A and Version B will fit the Glock 19, with Version A offering a quick-detach system for users who frequently switch lights between firearms.
Conclusion
The SureFire X300 is a top-tier weapon-mounted light, perfect for tactical and professional use. Whether you choose Version A for its quick-attach convenience or Version B for its secure fit, both provide the same powerful 1,000-lumen output. The addition of the X300 Turbo model offers a higher candela option for those who need more beam intensity and long-range performance. Additionally, the X300 fits a wide range of firearms, including the Glock 19, making it a versatile option for anyone looking for a reliable, high-quality weapon light.
If you’re looking to enhance your firearm with a durable, high-performance tactical light, the SureFire X300 Ultra or the X300 Turbo is an excellent choice.
